If the vehicle facility is a vehicle headlight, the vehicle facility control device 21 controls the optical axis direction of the headlight based on the second set value.

<A-2. Operation>
FIG. 2 is a flowchart showing the operation of the set value determining apparatus 101. Hereinafter, the operation of the set value determination apparatus 101 will be described with reference to FIG. First, the passenger information acquisition unit 11 acquires passenger information (step S11). The passenger information includes identification information for specifying the passenger of the vehicle and seat information for specifying the seat on which the passenger is seated.

Next, the set value determining unit 12 acquires the passenger information from the passenger information acquiring unit 11, and determines the first set value based on the combination of passengers that distinguish the seats obtained from the passenger information (step S12). ).

Next, the factor information acquisition unit 13 acquires factor information (step S13). Here, it is described that the factor information acquisition unit 13 acquires the factor information after the setting value determination unit 12 determines the first setting value. However, the timing at which the factor information acquisition unit 13 acquires the factor information may be before the set value determination unit 12 determines the first set value, or before the passenger information acquisition unit 11 acquires the passenger information. .

Next, the setting value correction unit 14 acquires the first setting value from the setting value determination unit 12 and the factor information from the factor information acquisition unit 13, and corrects the first setting value to the second setting value based on the factor information. (Step S14).

The set value determination device 101 according to the first embodiment determines a set value for the vehicle facility control device 21 to control the vehicle facility. The set value determination device 101 includes a passenger information acquisition unit 11, a factor information acquisition unit 13, a set value determination unit 12, and a set value correction unit 14. The passenger information acquisition unit 11 acquires passenger information. The passenger information includes identification information that identifies the passenger of the vehicle and seat information that identifies the seat on which the passenger is seated. The set value determination unit 12 determines the set value as the first set value based on the combination of the passengers that distinguish the seats obtained from the passenger information.

The factor information is information related to factors that affect the traveling of the vehicle other than the passenger information. The set value correction unit 14 corrects the first set value to the second set value based on the factor information. The vehicle equipment control device 21 controls the vehicle equipment with the second set value. The first set value is determined based on a combination of passengers with different seats. Therefore, the set value for the combination of passengers can be determined according to the passenger's preference. Further, since the first set value is corrected to the second set value based on the factor information, it can be corrected to the second set value from the viewpoint of passenger safety, for example. Therefore, the second set value is a value that takes into account both the passenger's preference and safety.

<B. Second Embodiment>
<B-1. Configuration>
FIG. 3 is a block diagram illustrating a configuration of the set value determining apparatus 102 according to the second embodiment. Compared with the configuration of the setting value determination device 101 according to the first embodiment, the setting value determination device 102 includes a setting value determination unit 12A instead of the setting value determination unit 12, and sets a setting value instead of the setting value correction unit 14. The difference is that a correction unit 14A is provided. The set value determination unit 12A includes a set value storage unit 121, and the set value correction unit 14A includes a correction value storage unit 141.

The set value storage unit 121 and the correction value storage unit 141 are configured by a storage medium such as a memory. The set value storage unit 121 stores set value information in which a combination of a passenger who distinguishes a seat and a set value are associated with each other. The correction value storage unit 141 stores correction value information in which the factor information and the correction value of the set value are associated with each other.

The set value determining device 102 is connected to the receiving device 23, the camera 24, the weather information receiving device 25, the navigation device 26, the pupil tracking device 27, the seat control device 211, the headlight control device 212, and the audio volume control device 213. These are configured to be usable.

In the present embodiment, the set value determining device 102 will be described as an in-vehicle device mounted on the vehicle 41. A receiving device 23, a camera 24, a weather information receiving device 25, a navigation device 26, a pupil tracking device 27, a seat control device 211, a headlight control device 212, and an audio volume control device 213 are also mounted on the vehicle 41.

The receiving device 23 is a device that communicates with the mobile terminal 22 carried by the passenger and receives the unique information from the mobile terminal 22. The unique information of the mobile terminal 22 is, for example, a MAC (Media Access Control) address. The receiving device 23 is, for example, an RFID (Radio Frequency Identification) reader that receives a MAC address from the portable terminal 22 by short-range wireless communication.

The RFID reader is installed in each seat of the vehicle 41, for example. When the reception range of the RFID reader is set to several tens of centimeters, each RFID reader can communicate with the mobile terminal 22 carried by the passenger who is mainly seated on the seat where the RFID reader is installed. The MAC address of the portable terminal 22 received by each RFID reader is sent to the passenger information acquisition unit 11 as passenger information.

The MAC address of the mobile terminal 22 received by each RFID reader is information for specifying the mobile terminal 22. And the information which specifies the portable terminal 22 is identification information which specifies a passenger on the assumption that the portable terminal 22 and a passenger correspond one-to-one. That is, the unique information of the mobile terminal 22 carried by the passenger is identification information for specifying the passenger.

For example, when the RFID reader installed in the driver's seat receives the MAC address of the portable terminal A, it becomes clear that the owner of the portable terminal A is seated in the driver's seat. Thus, the information indicating which RFID reader receives which MAC address identifies the seat on which the passenger is seated. Therefore, the MAC address of the portable terminal 22 received by each RFID reader is also seat information for specifying the seat on which the passenger is seated. That is, the unique information of the mobile terminal 22 that the receiving device 23 receives from the mobile terminal 22 is identification information that identifies the passenger. And the information of the seat in which the receiver 23 which received the specific information of the portable terminal 22 is installed becomes seat information for specifying the seat on which the passenger is seated.

The camera 24 images the interior of the vehicle 41. The occupant information acquisition unit 11 may acquire the occupant information by analyzing an image captured by the camera 24. In this case, for example, the passenger information acquisition unit 11 registers the passenger's face image in advance, and compares the registered face image with the photographed image of the camera 24, so that the passenger sitting in each seat is determined. Identify.

As a method for the passenger information acquisition unit 11 to acquire the passenger information, the method of receiving the unique information of the mobile terminal 22 by the receiving device 23 and the method of analyzing the captured image of the camera 24 have been described. The passenger information acquisition unit 11 may use one of these methods or both methods. When both methods are used, the passenger information acquisition unit 11 may supplement the measurement accuracy in one method by the other method. Further, according to the method of analyzing the captured image of the camera 24, it is possible to identify a passenger who does not carry the mobile terminal 22.

When the setting value determination unit 12A acquires the passenger information from the passenger information acquisition unit 11, the setting value determination unit 12A refers to the setting value information in the setting value storage unit 121 and sets the setting value corresponding to the combination of the passengers described in the passenger information. Is the first set value.

The captured image of the camera 24 is used not only for the passenger information acquisition unit 11 but also for the pupil tracking device 27. The pupil tracking device 27 is a device that provides factor information to the factor information acquisition unit 13 together with the weather information receiving device 25 and the navigation device 26.

The pupil tracking device 27 analyzes the image captured by the camera 24 and measures the movement of the driver's pupil. Here, the pupil tracking device 27 measures the movement of the pupil using the image captured by the camera 24, but may measure the movement of the pupil using the image captured by another camera such as an infrared camera. The measurement information of the pupil tracking device 27 is sent to the factor information acquisition unit 13. The factor information acquisition unit 13 acquires the physical condition information of the driver from the measurement information of the pupil tracking device 27. The physical condition information of the driver is information such as “large pupil blur” or “small pupil blur”. For example, the factor information acquisition unit 13 determines that “pupil blurring is large” if the number of times the direction of the pupil changes within a predetermined time is greater than the predetermined number of times, and “pupil blurring is small” if it is less than the predetermined number of times.

The weather information receiving device 25 receives current weather information of the travel region of the vehicle 41 from a server or the like outside the vehicle 41. The weather information received by the weather information receiver 25 is sent to the factor information acquisition unit 13.

The navigation device 26 is a device that provides route guidance for the vehicle 41. For example, when the destination of the vehicle 41 is set, the navigation device 26 searches for a travel route from the current location of the vehicle 41 to the destination. As described above, when the travel route of the vehicle 41 is set in the navigation device 26, the factor information acquisition unit 13 acquires the travel route information from the navigation device 26. The travel route information includes, for example, information such as the type of route such as whether the travel route is an expressway or a normal road, the speed limit of the road, or the number of lanes on the road.

The factor information acquisition unit 13 determines the physical condition information from the measurement information of the pupil tracking device 27, the weather information of the travel region of the vehicle 41 from the weather information reception device 25, and the travel route information of the vehicle 41 from the navigation device 26, respectively. Obtain as information. The factor information acquisition unit 13 does not need to acquire all of these, and may acquire at least one piece of information as factor information. The physical condition information, weather information, and travel route information are merely examples of factor information. The factor information may be information regarding any factor that affects the travel of the vehicle 41 other than the passenger information.

The set value correction unit 14A acquires the factor information from the factor information acquisition unit 13, and acquires the first set value from the set value determination unit 12A. Then, the set value correction unit 14A refers to the correction value information in the correction value storage unit 141, extracts the correction value of the set value corresponding to the factor information, and uses the correction value as the first set value as the second set value. To correct.

The second set value is output from the set value correction unit 14A to the seat control device 211, the headlight control device 212, or the audio volume control device 213, and the vehicle equipment is controlled by the second set value by these devices. The seat control device 211 performs position control in the front-rear direction of the driver seat or the passenger seat based on the second set value. The headlight control device 212 controls the direction of the optical axis of the headlight of the vehicle 41 based on the second set value. The audio volume control device 213 controls the playback volume of the audio device mounted on the vehicle 41 based on the second set value.

<B-2. Operation>
FIG. 4 is a flowchart showing the operation of the set value determination apparatus 102. Hereinafter, the operation of the set value determination apparatus 102 will be described along the flow of FIG. The flow in FIG. 4 starts when the vehicle 41 travels for the first time after closing the door, for example.

First, the passenger information acquisition unit 11 acquires passenger information (step S21). Specifically, the occupant information acquisition unit 11 acquires the occupant information by acquiring the unique information of the mobile terminal 22 from the receiving device 23, or acquires the occupant information by analyzing the captured image of the camera 24. To do.

Next, the set value determination unit 12A acquires passenger information from the passenger information acquisition unit 11. Then, the set value determination unit 12A refers to the set value information in the set value storage unit 121, extracts the set value corresponding to the combination of the passengers that distinguishes the seats obtained from the passenger information, and uses this as the first set value. Is determined (step S22).

FIG. 5 to FIG. 7 exemplify passenger combinations with different seats (hereinafter simply referred to as “passenger combinations”). Each cell in the tables shown in FIGS. 5 to 7 corresponds to the arrangement of each seat when the vehicle 41 is viewed from above. For example, the upper right cell represents the passenger in the driver seat, the upper left cell represents the passenger in the passenger seat, the lower right cell represents the passenger in the seat directly behind the driver seat, and the lower left cell represents the passenger in the passenger seat. . The above description is based on the vehicle 41 having a right steering wheel.

FIG. 5 shows a passenger combination 1 in which the driver's seat is “portable terminal A”, the passenger seat is “portable terminal B”, the seat directly behind the driver's seat is “portable terminal D”, and the passenger seat. The seat directly behind is “portable terminal C”. In the combination examples of FIG. 5 to FIG. 7, the mobile terminal is specified instead of the passenger, but the mobile terminal is specified on the assumption that the passenger and the mobile terminal have a one-to-one correspondence. It is synonymous with identifying the passenger.

FIG. 6 shows passenger combination 2. In combination 2, the passengers in the driver seat and the passenger seat are the same as in combination 1, but there are no passengers in the rear seats.

FIG. 7 shows passenger combination 3. In combination 3, the driver's seat is “portable terminal B”, the passenger seat is “portable terminal A”, the seat directly behind the driver seat is “portable terminal F”, and the seat just behind the passenger seat is “portable terminal E”.

8 and 9 show an example of setting value information stored in the setting value storage unit 121. FIG. As the setting values of the vehicle equipment, the setting value information in FIG. 8 shows the driver seat position setting value and the passenger seat position setting value, and FIG. 9 shows the audio volume setting value and the headlight height setting value. The driver seat position setting value is a setting value for the seat control device 211 to adjust the position in the front-rear direction of the driver seat, and the passenger seat position setting value is the seat control device 211 that adjusts the position in the front-rear direction of the passenger seat. It is a set value for The audio volume setting value is a setting value for the audio volume control device 213 to adjust the playback volume of the audio device, and the headlight height setting value is the headlight control device 212 of the optical axis of the headlight of the vehicle 41. This is a setting value for adjusting the height.

In the set value information in FIG. 8, for the combination 1, the driver seat position set value is “+3” and the passenger seat position set value is “+2”. For combination 2, the driver's seat position setting value is “+7” and the passenger seat position setting value is “+6”. The greater the driver seat position setting value is in the positive direction, the more the seat control device 211 adjusts the position of the driver's seat backward, and the greater the driver seat position setting value is in the negative direction, the more the seat control device 211 Adjust the driver's seat position forward. Similarly, as the passenger seat position setting value is larger in the positive direction, the seat control device 211 adjusts the position of the passenger seat backward, and as the passenger seat position setting value is larger in the negative direction, seat control is performed. The device 211 adjusts the position of the passenger seat forward.

That is, in the setting value information of FIG. 8, in the combination 2 from the combination 1, the setting value is determined so that both the driver's seat and the passenger seat are located further rearward. This is because in combination 1, there are passengers in the rear seat, whereas in combination 2, there are no passengers in the rear seats.

In the setting value information in FIG. 8, for the combination 3, the driver seat position setting value is “+2” and the passenger seat position setting value is “+1”. The passenger seat position setting value for combination 3 is smaller than the driver seat position setting value for combination 1. This is because the passenger carrying “portable terminal E” sitting in the seat immediately behind the passenger seat in combination 3 is larger than the passenger carrying “portable terminal D” sitting in the back of the driver seat in combination 1 It reflects that he is a good person.

In the setting value information of FIG. 9, for the combination 1, the audio volume setting value is “+50” and the headlight height setting value is “0”. For the combination 2, the audio volume setting value is “+60” and the headlight height setting value is “+10”. For the combination 3, the audio volume setting value is “+70” and the headlight height setting value is “−10”. As the audio volume setting value increases in the positive direction, the audio volume control device 213 adjusts the playback volume of the audio device to be larger. As the audio volume setting value increases in the negative direction, the audio volume control device 213 increases. Adjust the audio device playback volume to be low. Further, as the headlight height setting value is larger in the positive direction, the headlight control device 212 adjusts the position of the optical axis of the headlight higher and the headlight height setting value is larger in the negative direction. The headlight control device 212 adjusts the position of the optical axis of the headlight to be lower.

In the set value information of FIG. 9, among the

combinations

1, 2, and 3, the audio volume setting value for the combination 1 is the smallest, and the audio volume setting value for the combination 3 is the largest. Thus, the audio volume setting value is determined by the combination of the passengers. For example, the audio volume setting value can be reduced for a combination when boarding the vehicle 41 with a family, and the audio volume setting value can be increased for a combination when boarding the vehicle 41 with friends.

In the setting value information of FIG. 9, the headlight height setting value for the combination 2 is set larger than the headlight height setting value for the combination 1. This is because in the combination 2 in which no passenger is seated in the rear seat, the front of the vehicle 41 sinks slightly, so that the deviation of the optical axis of the headlight caused thereby is corrected. Further, the headlight height setting value for the combination 3 is set smaller than the headlight height setting value for the combination 1. This is because the passenger seated in the rear seat in combination 3 is heavier than the passenger seated in the rear seat in combination 1 and the rear of the vehicle 41 sinks more, thereby causing the deviation of the optical axis of the headlight. This is to correct the above.

The setting value information shown in FIGS. 8 and 9 defines setting values for controlling vehicle equipment for a combination of passengers with different seats. The set value information is input to the set value determining device 102 by a user such as a driver of the vehicle 41 using an input device (not illustrated in FIG. 3) and stored in the set value storage unit 121. Alternatively, the set value determination unit 12A may be a learning system that stores the set value and the combination of the passenger each time the equipment of the vehicle 41 is used, and updates the set value information based on these. . In any case, since the setting value information is determined according to the user's preference, the first setting value determined by the setting value determining unit 12A is in accordance with the user's preference.

4, after step S22, the set value determination device 102 determines whether or not the door of the vehicle 41 has been opened and closed (step S23). Here, opening and closing of the door means closing after the door is opened. When the set value determination device 102 detects opening / closing of the door, the process returns to step S21 and the passenger information acquisition unit 11 acquires the passenger information. If the set value determination device 102 does not detect the opening / closing of the door in step S23, the factor information acquisition unit 13 acquires factor information (step S24).

Next, the set value correction unit 14A acquires factor information from the factor information acquisition unit 13. Then, with reference to the correction value information in the correction value storage unit 141, it is determined whether or not the first set value needs to be corrected (step S25). Specifically, the set value correction unit 14A determines that correction is necessary when the factor information acquired from the factor information acquisition unit 13 is associated with the correction value in the correction value information. Is deemed unnecessary.

FIG. 10 exemplifies correction value information stored in the correction value storage unit 141. In the correction value information of FIG. 10, for the weather information of “thunderstorm”, the correction value of the driver seat position setting value is “−2”, the correction value of the audio volume setting value is “−10”, and the headlight height setting The correction value is “+5”. Here, the correction value of the driver's seat position setting value is determined with the aim of widening the driver's field of view by moving the driver's seat forward. The correction value for the audio volume setting value is determined with the aim of increasing the driver's concentration on driving by reducing the playback volume of the audio device. The correction value of the headlight height setting value is determined with the aim of widening the driver's field of view by increasing the optical axis of the headlight and irradiating the light of the headlight over a wide range.

In the correction information in FIG. 10, the audio volume setting value correction value is “−10” and the driver seat position setting value and the headlight height setting value correction are both “0” with respect to the route information of “highway entry”. It is. Here, the correction value of the audio volume setting value is determined with the aim of increasing the driver's concentration on driving by reducing the playback volume of the audio device.

In the correction information of FIG. 10, the driver seat position setting value correction value is “−3”, the audio volume setting value correction value is “+10”, and the headlight height setting with respect to the physical condition information of “large pupil blurring”. The correction value is “0”. Here, the correction value of the driver's seat position setting value is determined with the aim of moving the driver's seat forward and widening the driver's field of view. Further, the correction value of the audio volume setting value is determined with the aim of increasing the playback volume of the audio device to increase the driver's arousal level.

If the correction is not necessary in step S25, the process of the set value determination device 102 returns to step S23. At this time, the first set value determined by the set value determining apparatus 102, that is, the uncorrected set value is output to the sheet control apparatus 211 or the like. On the other hand, if correction is necessary in step S25, the set value correction unit 14A corrects the first set value to the second set value with the correction value corresponding to the factor information (step S26). For example, in the example shown in FIGS. 5 to 10, when the combination of the passengers is combination 1 and the route information is “highway entry”, the set value correction unit 14A sets the audio volume setting value “+50”. Is added with the correction value “−10” to obtain the audio volume setting value “+40”. The setting value thus corrected, that is, the second setting value is output to the audio volume control device 213 and the like. Thereafter, the flow returns to step S23.

FIG. 10 shows a plurality of factors that should correct the set value. If these factors occur simultaneously, the set value correcting unit 14A determines the correction value by taking the average of the correction values for each factor. May be.

<C. Embodiment 3>
<C-1. Configuration>
FIG. 11 is a block diagram showing a configuration of the set value determining apparatus 103 according to the third embodiment. Compared with the configuration of the setting value determination device 102 of the second embodiment, the setting value determination device 103 further includes an attribute information acquisition unit 15 and includes a setting value determination unit 12B instead of the setting value determination unit 12A. . The set value determination unit 12B includes an attribute information storage unit 122 in addition to the configuration of the set value determination unit 12A. In addition to the configuration described in the second embodiment, the set value determination device 103 is connected to the weight measurement device 28 and is configured to be usable.

The attribute information acquisition unit 15 acquires the attribute information of the indefinite passenger. An indefinite passenger is a passenger who cannot acquire identification information by the passenger information acquisition unit 11 and a passenger whose combination is not described in the setting value information stored in the setting value storage unit 121. The attribute information is information indicating attributes that are characteristics of the passenger. For example, the height or weight of the passenger corresponds to the attribute.

The weight measuring device 28 is installed in each seat of the vehicle 41 and measures the weight of the passenger seated in each seat. The weight information of the passenger measured by the weight measuring device 28 is sent to the attribute information acquisition unit 15 as attribute information.

Further, the attribute information acquisition unit 15 acquires a captured image of the camera 24. The attribute information acquisition unit 15 analyzes the captured image of the camera 24 and measures the height of the passenger. That is, the attribute information acquisition unit 15 acquires the passenger's height information as attribute information by analyzing a captured image of the camera 24.

The attribute information storage unit 122 is configured by a storage medium such as a memory. The attribute information storage unit 122 stores registered passenger attribute information. The registered passenger is a passenger whose combination is described in the setting value information stored in the setting value storage unit 121.

In the second embodiment, the description will be made on the assumption that all the passengers of the vehicle 41 are specified by the passenger information and the setting values for the specified combinations of the passengers are stored in the setting value storage unit 121. went. Therefore, the set value determining unit 12A can uniquely set the first set value for the identified passenger combination. The setting value determination unit 12B according to the present embodiment also determines the first setting value in the same manner as the setting value determination unit 12A according to the second embodiment under such circumstances.

However, when there is an indefinite passenger among the passengers of the vehicle 41, that is, when the passenger information acquisition unit 11 cannot acquire the identification information of at least some passengers, or the setting value for the combination of passengers is the setting value. If not stored in the storage unit 121, the set value determination unit 12B replaces the indefinite passenger with the registered passenger and determines the first set value.

<C-2. Operation>
Hereinafter, the operations of the passenger information acquisition unit 11 and the set value determination unit 12B according to the third embodiment will be described with reference to the flowchart of FIG.

First, the passenger information acquisition unit 11 acquires a captured image of the camera 24, analyzes the captured image, and acquires seat information (step S31).

Next, the passenger information acquisition unit 11 acquires the unique information of the mobile terminal 22 from the receiving device 23 (step S32). Here, the unique information itself becomes the identification information of the passenger, and the information of the seat where the receiving device 23 that received the unique information is installed becomes the seat information.

Next, the set value determination unit 12B determines whether there is an indefinite passenger (step S33). Here, for example, when it is determined that the passenger is seated in the passenger seat based on the analysis of the captured image of the camera 24, the setting value determination unit 12B causes the receiving device 23 installed in the passenger seat to the portable terminal 22 If the specific information is not received, the passenger seated in the passenger seat is determined as an indefinite passenger. As described above, when there is a discrepancy between the seat information acquired from the captured image of the camera 24 and the reception status of the receiving device 23, the passenger who has not received the identification information by the receiving device 23 is determined as an indefinite passenger. .

In addition, for all seats that are determined to be seated based on the analysis of the captured image of the camera 24, even if the receiving device 23 installed in each seat receives the unique information of the mobile terminal 22, When the set value for the combination of passengers specified by the unique information of the terminal 22 is not described in the set value information, the set value determination unit 12B determines that all the passengers related to the combination are undefined passengers.

If there is no indefinite passenger in step S33, the setting value corresponding to the combination of the passengers is determined as the first setting value (step S37). Here, similarly to the setting value determination unit 12A of the second embodiment, the setting value determination unit 12B sets the setting value associated with the passenger's combination that distinguishes the seat in the setting value information as the first setting value. And

On the other hand, when there is an indefinite passenger in step S33, the processing of the set value determination device 103 proceeds to step S34. Hereinafter, description will be given by taking the passenger combination 4 shown in FIG. 13 as an example. In the combination 4, the passenger specified by the portable terminal A in the driver's seat, the portable terminal B in the passenger seat, and the portable terminal C in the seat directly behind the passenger seat is seated, and the undefined passenger is seated in the seat immediately behind the driver seat. To do.

The attribute information acquisition unit 15 acquires the attribute information of the indefinite passenger (step S34). Specifically, the attribute information acquisition unit 15 acquires the indefinite passenger's height information from the photographed image of the camera 24 as attribute information, and acquires the indefinite passenger's weight information as the attribute information from the measurement information of the weight measurement device 28. To do.

Next, the set value determination unit 12B acquires the attribute information of the indefinite passenger from the attribute information acquisition unit 15. Then, the set value determination unit 12B determines whether there is a registered passenger whose attribute information is similar to that of the indefinite passenger (step S35). Specifically, the set value determination unit 12B refers to the attribute information stored in the attribute information storage unit 122 and searches for registered passengers having attribute information similar to the attribute information of the indefinite passenger. When the attribute information is weight information and height information, for example, a registered passenger whose weight falls within the range of ± 5 kg and height of ± 5 cm with respect to the indefinite passenger is referred to as a registered passenger whose attribute information is similar to the indefinite passenger. To do. If there are a plurality of similar registered passengers, the registered passenger with the closest attribute information is selected.

If there is no registered passenger whose attribute information is similar to that of the indefinite passenger, the set value determination unit 12B sets the default value as the first set value (step S38). 14 and 15 show setting value information stored in the setting value storage unit 121 of the setting value determination unit 12B. This set value information is similar to that shown in FIGS. 8 and 9, except that default set values are described. In the example of FIGS. 14 and 15, the setting value determination unit 12B sets the driver seat position setting value “+5”, the passenger seat position setting value “+2”, and the audio volume setting value for the combination 4 in FIG. “+60” and the headlight height setting value are set to “+5”. This completes the processing of the set value determination unit 12B. In the examples of FIGS. 14 and 15, there is only one default setting value, but there may be a plurality of types. For example, the set value determination unit 12B may use different default values as the first set value when the indefinite passenger is 165 cm-175 cm in height and 50 kg-55 kg in weight, and in the case where the height is 165 cm-175 cm and 55 kg-60 kg in weight. good.

On the other hand, when there is a registered passenger whose attribute information is similar to that of the indefinite passenger, the set value determination unit 12B replaces the indefinite passenger with a registered passenger whose attribute information is similar (step S36). For example, when the attribute information of the owner of “portable terminal D” is similar to the attribute information of the indefinite passenger, the indefinite passenger is replaced with the owner of “portable terminal D” in the combination 4 shown in FIG.

Next, the set value determining unit 12B refers to the set value information and determines a set value corresponding to the passenger combination as the first set value (step S37). Since the indefinite passenger is replaced with the registered passenger in step S36, the set value determining unit 12B determines the set value corresponding to the replaced passenger combination. In the combination 4 shown in FIG. 13, the combination 1 is obtained by replacing the indefinite passenger with the holder of the “portable terminal D”. Accordingly, the set value determining unit 12B determines the set value corresponding to the combination 1 in the set value information as the first set value. As shown in FIGS. 14 and 15, the driver seat position setting value is “+3”, the passenger seat position setting value is “+2”, the audio volume setting value is “+50”, and the headlight height setting value is “0”. . This completes the processing of the set value determination unit 12B.

As described above, the set value determination apparatus 103 according to the third embodiment includes the attribute information acquisition unit 15 that acquires the attribute information of the indefinite passenger in addition to the configuration of the first embodiment. An indefinite passenger is a passenger for whom the passenger information acquisition part 11 cannot acquire identification information, or a passenger whose combination is not described in the set value information. The set value determination unit 12B refers to the attribute information of the registered passenger whose combination is described in the set value information, replaces the indefinite passenger with the registered passenger with similar attribute information, and the combination of the passengers after the replacement The first set value is determined based on the above. With the above configuration, the set value determination device 103 can appropriately set the first set value for a combination of passengers including indefinite passengers.
