Description

The invention relates to a method and a device for interacting a vehicle system of a motor vehicle with a user.

During trips with a motor vehicle, there is often a desire, in particular for longer trips, for a conversation of the motor vehicle driver and / or other vehicle occupants.

The US 6,401,033 B1 discloses z. B. a method for operating a navigation system of a motor vehicle. The method accepts input from a user indicating that the user is interested in playing a game. The method further comprises running a game program on the navigation system, the game program including game rules and using data from a geographic database. Further, the game program uses the game rules to perform the game by means of a user interface of the navigation system. Further, the method accepts inputs from a user of the navigation system to determine a route to a desired destination point of the user. The method further comprises determining a position of the navigation system and providing data containing information about the position to the game program. Further, the document discloses that a navigation system with a game option does not allow games to be played in case they distract an automobile driver. Also, the system does not allow playing under critical driving conditions.

In order not to leave a motor vehicle driver and / or other passengers in a role of purely passive consumers of a conversation, it is desirable to allow interaction between the motor vehicle driver and / or other vehicle occupants and the vehicle system implementing an entertainment program.

The technical problem arises of providing a method and a device for the interaction of a user, in particular a motor vehicle driver and / or other vehicle occupants, with a vehicle system implementing an interactive entertainment program, which can provide a multiplicity of different entertainment programs and at the same time safety requirements, for example Requirements for a distraction of a motor vehicle driver, meet.

The solution of the technical problem results from the objects with the features of claims 1 and 10. Further advantageous embodiments of the invention will become apparent from the dependent claims.

A method for interacting with a user of a vehicle system is proposed. In this case, the vehicle system preferably provides a multiplicity of entertainment programs, the course or execution of which requires interaction with a user, for example a motor vehicle driver and / or other vehicle occupants. The vehicle system may be an already known vehicle infotainment system. In particular, the vehicle system comprises at least one input device for inputting user inputs, at least one evaluation device for evaluating at least the user inputs and at least one output device for outputting information to the user. Further, the vehicle system may also include storage units for storing information necessary for the entertainment program.

An initial state, but preferably each system state, is assigned at least one state information and at least one subsequent state. In this case, the system state or initial state describes the state of the vehicle system, in particular of the (technical) devices included in front of this vehicle system, in a state of the entertainment program being run. A change between two system states, in particular a change from an initial state to a subsequent state, is carried out if, in the initial state, a follow-state-specific transition condition is fulfilled. In this case, an evaluation device evaluates at least one user input in the initial state. The at least one sequence state-specific transition condition of the initial state is fulfilled if the evaluated user input matches at least one predetermined user input of the transition condition. The evaluation of a user input in this case also includes evaluating whether a user input takes place in a predetermined, state-specific condition duration at all. If, for example, there is no user input in the status period, then a temporary transitional condition can be fulfilled and a change to a corresponding subsequent state can take place (automatic changeover). After the change to the subsequent state, at least one output device outputs the state information associated with the subsequent state.

A subsequent state of an output state may be a follow-up state or a predecessor state of the output state. In a predecessor state is changed from the initial state, for example, then, if the evaluated user input matches a predetermined user input, a return Operation is assigned. In this case, a plurality of follow-up states, in particular several follow-on states and exactly one predecessor state, can be assigned to a system state. The successor states assigned to a system state can here be understood as so-called static follow-on states, wherein a change from the initial state into exactly these predetermined static follow-up states takes place when the transition condition associated therewith is fulfilled. The predecessor state can be referred to here as a dynamic subsequent state. The predecessor state here denotes the state from which the current initial state has been changed. Of course, it is possible to change from different system states to the current initial state. The predecessor state-specific transition condition is therefore not statically always assigned the same system state, but depending on the expiration of the entertainment program a special predecessor state from a set of possible predecessor states.

Preferably, information about a predecessor state of the initial state, for example, in a memory device, stored, for example, when changing to a subsequent state. These allow advantageously a dynamic assignment of a predecessor state to a follow-state specific transition condition, the z. B. is associated with a back operation.

Also, a period of remaining in the initial state can be detected, evaluated and stored. The duration of the remaining can be compared with the previously mentioned state duration. In this case, a change to the subsequent state, for example, take place only if the time duration of remaining in the initial state has exceeded a predetermined state-specific state duration, even if further follow-state specific transition conditions are already met. As a result, too fast state changes are avoided in an advantageous manner that confuse or distract a motor vehicle driver.

A sequence condition specific transition condition may include multiple subconditions or subconditions. For example, a first sub-condition may be that a user input corresponds to a predetermined user input. Also, a sub-condition may be that a predetermined period of time (state duration) has remained in the current state. As explained in more detail below, another sub-condition may be that a driving state corresponds to a predetermined driving state. In this case, it is only then possible to switch from an initial state to a subsequent state if all or certain sub-conditions or sub-conditions of the respective sequence state-specific transition conditions are fulfilled.

Furthermore, the output of the status information can only take place after a predetermined period of time has elapsed after the change from the initial state to the subsequent state. This can be prevented in an advantageous manner for a motor vehicle driver too fast temporal presentation of information that could distract or confuse this.

Furthermore, a user input can only be evaluated in this subsequent state after the state information has been output in the subsequent state. This results in an advantageous manner that an input of information does not temporally conflict with an output of information.

The proposed method thus advantageously allows interaction between a vehicle system and a user, with the inventive method steps reducing or avoiding distraction and confusion of a motor vehicle driver. It thus advantageously enables a conversation of a motor vehicle driver and / or other vehicle occupants, without jeopardizing the safety of these users.

In a further embodiment, the at least one state information is an acoustic state information. After the change to the subsequent state, at least one acoustic output device outputs the acoustic state information associated with the subsequent state. For this purpose, existing speakers can be used in an advantageous manner in the motor vehicle. By issuing acoustic status information, an interactive radio play can thus advantageously be carried out by means of the method according to the invention in the motor vehicle. Also possible are rate or quiz games. Also possible are vocabulary or grammar trainers. The output of acoustic state information further advantageously allows a motor vehicle driver and / or other vehicle occupants can receive information without z. B. avert a view of a traffic event.

Of course, it is also possible to display visual status information on a corresponding display device. Here, the visual state information is preferably static state information, such as a static image. Further preferably, visual information does not contain any hints for resolution, as otherwise a user gets his or her view of a traffic situation for the purpose of solving or participating in the entertainment program of a traffic event could turn away. However, the visual state information advantageously results in an improved interaction between a user and the vehicle system, since additional information can thereby be displayed. Here at a visual display can be made depending on certain conditions. For example, a predetermined font size may be used.

In a further embodiment, the evaluation device additionally evaluates at least one vehicle state in the initial state. Here, in the initial state, a follow-state-specific transition condition is met if the evaluated user input matches at least one predetermined user input and the at least one evaluated vehicle state matches a predetermined vehicle state. The term vehicle state here includes states of the vehicle system according to the invention integrating motor vehicle, such. Shutdown, forward drive, reverse drive, cornering, highway driving, highway driving, city traffic driving, parking, passing, turning and other analog vehicle conditions. The term vehicle state here also includes features and / or properties of vehicle states, such as speed, acceleration, steering angle (steering angle), global position of the motor vehicle and other properties and / or features. The term vehicle condition also includes a z. B. by means of a navigation system planned route of the motor vehicle.

In a preferred embodiment, the evaluation device determines the at least one vehicle state as a function of data transmitted to the evaluation device. For this purpose, the evaluation device is connected in terms of data technology with at least one sensor arranged in the motor vehicle and / or with at least one receiving device for receiving external data. The at least one evaluation device can in this case be connected, for example, to a bus system, for example a CAN bus, of the motor vehicle. In this case, the evaluation device can receive data from subscribers likewise connected to the bus system, for example sensors. For example, the evaluation device can receive a speed of a speed sensor, a global position of a GPS sensor, information about a rain condition of a rain sensor, a steering angle of a steering angle sensor, a brake pedal position of a brake pedal sensor and other data arranged in the motor vehicle sensors. Alternatively or cumulatively, the evaluation device can receive external data, for example from a Car2X communication from other motor vehicles and / or a traffic infrastructure, for example a traffic control center, via a receiving device.

As a result, it is advantageously possible to integrate vehicle-specific data into a sequence of an entertainment program as well as as a result of the method according to the invention for interaction. For example, depending on a global position of the vehicle, it may be changed to a subsequent state that contains information and / or questions that are adapted to the geographic features corresponding to the global position. Approaches the motor vehicle, for example, a city or this motor vehicle passes the city, so z. For example, questions and / or information concerning, for example, a population of this city will be spent.

Also, z. B. in response to a current position of the motor vehicle and a planned route to a desired destination and a current fuel consumption are queried whether the desired destination can be reached with a remaining amount of fuel. Thus, information for guiding the motor vehicle can be conveyed to the motor vehicle driver in a playful manner in an advantageous manner.

It is also conceivable external data, d. H. data generated outside of the motor vehicle to integrate into a flow of the entertainment program and as a result of the method of interaction. For example, congestion information can thus be integrated into the entertainment program.

In a further embodiment, the system changes from the initial state to a time-out state if no user input is detected in the initial state during a predetermined period of time. Here, the predetermined period of time may be dependent on a vehicle state. For example, in vehicle states rated as dangerous or critical, a predetermined period of time may be longer than in non-hazardous or non-critical vehicle conditions. In this case, a dangerous or critical vehicle state can be determined by the evaluation device as a function of the internal or external data transmitted to this evaluation device. Internal data designate the data generated by sensors arranged in the motor vehicle and / or the data generated by control and / or evaluation devices arranged in the motor vehicle. For example, a critical vehicle condition can be determined as a function of internal data if a predetermined negative acceleration is undershot (strong braking operation). Also, a critical vehicle condition may be determined in response to external data if the vehicle is approaching a traffic jam.

It is also conceivable that the evaluation device does not determine a critical or dangerous vehicle state as a function of the internal or external data transmitted to the evaluation device, but rather that a signal encoding a dangerous or critical vehicle state, for example from a central control unit of the motor vehicle, is transmitted to the evaluation device ,

It should be noted that in some states, the recognition of no user input causes an (automatic) change to a subsequent state, which is not a time-out state.

In the time-out state, a state information specific to the time-out state is output here. Preferably, an output of the state information which is specific for the time-out state takes place only after a predetermined period of time has elapsed, wherein this predetermined time duration, as explained above, can once again depend on a vehicle state. A state information can, for. B. be issued as an acoustic demand for a user input. This allows a user to be reminded in an advantageous manner, taking into account dangerous or critical vehicle conditions to an entertainment program started by him. The proposed time-out handling allows this in an advantageous manner that an interactive implementation of the entertainment program is possible even in times of lack of user input, without a complete cancellation of the entertainment program.

In a further embodiment, switching from the initial state to a help state if a user input is detected that does not match any particular user input of transient conditions of the output state or a user input is detected that corresponds to a predetermined user input of a transition condition for a change in the help State matches. In the help state, state information may contain information about possible user inputs in the predecessor state of the help state. For example, the user can be audibly and optionally visually output the permissible, predetermined user inputs of the predecessor state. As previously explained, an output of state information of the Help state just in case after a predetermined period of time after a change to the Help state, wherein the predetermined time period may be dependent on a vehicle state. In this way, it is possible to react in an advantageous manner to unintelligible user inputs, which are entered by a user, for example, due to a suddenly occurring critical driving situation.

In a further embodiment, switching from the initial state to a deactivated state is made if a user input coinciding with a predetermined user input of a transition condition for a transition from the initial state to the deactivated state or if a predetermined vehicle state is detected or if during a predetermined idle period no user input is detected. A predetermined vehicle state may be, for example, pulling out the ignition key. Also, the predetermined vehicle state may be a predetermined critical vehicle state. For example, it is possible to change to a deactivated state if a collision or an impending collision with another road user has been detected. In this case, a state change is possible independently of a user input. As previously stated, the vehicle condition may be determined depending on internal or external data. To distinguish a change in a time-out state of a change in a deactivated state, z. B. only from a time-out state after the expiration of the predetermined inactive duration from the time-out state to the deactivated state is changed.

This advantageously results in an entertainment program being deactivated if a user is not interested in continuing the entertainment program and / or entering predetermined (critical) vehicle conditions. In a deactivated state, energy consumption of the vehicle system for carrying out the method according to the invention is advantageously reduced in this case. This results in an advantageous manner a reduced energy consumption of the vehicle system in the deactivated state.

In a further embodiment, the assignments of the at least one state information to each system state, the assignment of the sequence state-specific transition conditions to each system state, and at least the assignment of at least one successor state to a follow-state-specific transition condition are defined in a state model. The state model is stored in a memory device. Furthermore, data of state information, for example acoustic and / or visual data, are stored in a storage device for information. The evaluation unit is connected in terms of data technology with the storage device of the state model and with the storage device for information. In the state model, therefore, the static sequence states and their assignment are too a follow-state-specific transition condition for each system state is set and stored. Furthermore, transition conditions are also defined and stored in the state model, which, however, can lead to previously unknown subsequent states, for example the dynamic predecessor states. However, a predecessor state can then be defined and stored in the state model if a current state can only be reached from this predecessor state, ie the predecessor state is also a static subsequent state. The memory devices of the state model and for information can be embodied here combined as a common memory device. For example, the state model storage device and the information storage device may be configured as an external removable storage device, e.g. B. as a CD.

This advantageously results in a universality of the method according to the invention for various forms of entertainment programs. By exchanging the memory devices, various forms of entertainment programs, for example radio plays or vocabulary trainer, can be presented to a user by means of the method according to the invention. By exchanging the memory devices, in this case links between states, the required transmission conditions and the contents of state-specific state information can be exchanged. However, flow control of the interaction based on these links, transition conditions and contents by the evaluation device remains the same.

In a further embodiment, user input is possible by means of an acoustic input device and / or a haptic input device. For this purpose, a device for speech recognition can evaluate an acoustic user input, for example a voice command. A haptic input device can be designed, for example, as a multifunction steering wheel. In this case, user inputs are possible by means of the input elements arranged on the multifunction steering wheel, for example by means of the pushbuttons arranged on the multifunction steering wheel. Also, a haptic input device may be designed as a touchscreen or as a touchpad, wherein a touchscreen is spatially arranged on a display device, for example a display, and a touchpad is arranged spatially separated from the display device. In this case, functional subregions of the touchscreen or of the touchpad can be assigned predetermined operations, wherein a user input by means of an actuating element, for example by means of a finger and / or a pen, is effected by touching the touchscreen or the touchpad in the region of these functional subregions. As a result, virtual operator control elements for user inputs can advantageously be displayed on a display device, for example a display. Preferably, user entries are made by means of a user interface provided in the vehicle, which comprises a touchscreen and a display device, for example a display. For example, existing radionavigation systems that include a touchscreen can be used.

Further proposed is a device for interacting a vehicle system with a user in a motor vehicle, wherein the device comprises at least one input device, at least one evaluation device and at least one output device. In this case, by means of the device according to the invention advantageously one of the aforementioned methods can be carried out.

The invention will be explained in more detail with reference to an embodiment. The figures show:

Hereinafter, like reference numerals designate elements having the same or similar technical features.

In 1 is a device according to the invention 1 presented for interaction. The device 1 includes an evaluation device 2 , An institution 3 for speech recognition, a touch screen 4 , an output device 5 for the output of acoustic information as well as a first storage device 6 and a second storage device 7 , By means of the device 3 For speech recognition, user inputs are in the form of voice commands from a user of the device 1 can be received and evaluated for interaction. The user inputs evaluated in this way are taken from the unit by data technology 3 for speech recognition to the evaluation device 2 transfer. Analog are by means of the touch screen 4 haptic user input, for example by means of a control element, for. As a finger or a pen, can be evaluated, evaluated, the evaluated user input data technically to the evaluation 2 be transmitted. Next, the evaluation is in data communication with the first memory device 6 in which a z. In 3 represented state model is stored. Also stands the evaluation device 2 in data communication with the second memory device 7 in which data of status information of individual system states, for example image files or audio files, are stored. Next is the evaluation 2 in data communication with a GPS sensor 16 and a speed sensor 17 that in one the device 1 comprehensive motor vehicle are arranged. Depending on the unit 3 for speech recognition and / or the touch screen 4 transmitted, evaluated user inputs as well as those from the GPS sensor 16 and the speed sensor 17 transmitted data to the vehicle state checks the evaluation 2 Whether in a current system state transition conditions for a change to a current state associated with this state condition are met. If this is the case, the evaluation device changes 2 in the corresponding subsequent state and loads the sequence-state-specific data from the second memory unit 7 , Next is the evaluation with a unit 5 connected to the output of acoustic information data technology. These are the ones from the storage unit 7 according to the current state loaded acoustic data by means of the output device 5 acoustically output. Also stands the evaluation 2 in data communication with a display device 8th that z. B. as the Tochscreen 4 associated display can be executed. This z. B. the current state associated visual state information, eg. In the form of image files on the display 8th be displayed.

In 2 FIG. 3 is a schematic flow diagram of a change of system states. Initially, the vehicle system is in an initial state AZ. After a predetermined period of time T1 in this case by means of z. In 1 illustrated acoustic output device 5 and the display device 8th State information associated with the initial state is output in an output step S1. The acoustic state information associated with the initial state AZ here contains a question that prompts a user for a response. Subsequently, in a waiting step S2, a user input is waited for. If there is a user input N1, which coincides with a predetermined user input of a transition condition for a change from the initial state AZ to a subsequent state FZ, the evaluation device changes 2 (please refer 1 ) in the corresponding subsequent state FZ. After the predetermined period of time T1, the acoustic output device can again be used in an output step S1 5 and the display device 8th output acoustic and visual status information, which are assigned to the subsequent state FZ. In the waiting step 2 a user input N2, which does not coincide with any predetermined user input of a transition condition of the output state AZ in any further subsequent state, the evaluation device changes 2 into a help state HZ. In an output section S1 of the help state HZ, by means of the acoustic output device 5 and the display device 8th audible and visual status information output, which are associated with the help state HZ and inform a user about the possible predetermined user input in the initial state AZ, including via the user input N1. After this, after a state period T4, a return to the waiting step S2 and to the initial state AZ occurs automatically. Also, a return could be made to the output section S1 of the output state AZ, in which case the state information is output again. If there is no user input in the waiting step S2 during a further predetermined time period T2, then the evaluation device changes 2 in a time-out state TZ. After that, after the first predetermined period T1 in an output step S1, an output of acoustic and visual status information, which is assigned to the time-out state TZ, takes place. In a further waiting step S2 is then waited for a user input in the time-out state TZ. If no user input takes place within a predetermined inactive period T3, the evaluation device changes 2 in a deactivated state DZ, in which the inventive method is terminated. If there is a permissible user input N1, the time-out state TZ, the evaluation device changes 2 in the waiting step S2 of the initial state AZ. If an inadmissible user input N2 occurs, the evaluation device changes 2 into a help state HZ.

In 3 a schematic state model is shown. The state model contains information about a combination of states Z1, Z2a, Z2b, Z3a, Z3b, Z3c, Z3d, Z4a, Z4b, Z4c, Z4d, Z5a, Z5b, Z5c, Z5d, Z5e as well as end states EZ1, EZ2, EZ3, EZ4 , EZ5. By way of example, successor states Z5b, Z5c, HZ, TZ are assigned to a state Z4b. These successor states Z5b, Z5c, HZ, TZ can be referred to here as static sequence states. This means that, if the corresponding sequence state-specific transition conditions are fulfilled, from the state Z4b always into the respective following state Z5b, Z5c, HZ, TZ is changed. Furthermore, the state Z4b is assigned the predecessor states Z3a, Z3b. These predecessor states can be referred to as dynamic follow-on states. For example For example, in state Z4b, a user input corresponding to a predetermined user input of a transition condition associated with a return operation may be transitioned from state Z4b to either predecessor state Z3a or Z3b, since state Z4b consists of both states Z3a, Z3b is reachable. By contrast, the state model for state Z3b contains only static sequence states Z4a, Z4b, Z2a, HZ, TZ. In this case, the state Z3b can be reached exclusively from the predecessor state Z2a. A user input that corresponds to a predetermined user input of a transition condition to which a back operation is assigned can only cause a change to the state Z2a. State information is assigned to each of the states Z1, Z2a, Z2b, Z3a, Z3b, Z3c, Z3d, Z4a, Z4b, Z4c, Z4d, Z5a, Z5b, Z5c, Z5d, Z5e as well as end states EZ1, EZ2, EZ3, EZ4, EZ5 , The data of this state information are in this case in a storage device for information, for example, the in 1 shown second memory device 7 , saved. This in 3 illustrated state model, in particular the assignment of state information to a state Z1, Z2a, Z2b, Z3a, Z3b, Z3c, Z3d, Z4a, Z4b, Z4c, Z4d, Z5a, Z5b, Z5c, Z5d, Z5e and end states EZ1, EZ2, EZ3 , EZ4, EZ5, the assignment of sequence state-specific transition conditions to a state Z1, Z2a, Z2b, Z3a, Z3b, Z3c, Z3d, Z4a, Z4b, Z4c, Z4d, Z5a, Z5b, Z5c, Z5d, Z5e and end states EZ1, EZ2 , EZ3, EZ4, EZ5 and at least the assignment of static sequence states to a sequence state-specific transition condition, are in this case in a memory device of the state model, for example, the in 1 shown first storage unit 6 , saved.

In 4 is a schematic functional linkage shown. At a program or execution level 9 Here is the in 1 illustrated evaluation device 2 arranged. This is arranged in this case in a motor vehicle, which is the device according to the invention 1 (please refer 1 ). At a data level 10 Here are the first and second memory unit 6 . 7 arranged, wherein the first storage unit 6 the Z. In 3 illustrated state model contains and the storage unit 7 contains the data, such as image and audio data, which the state information of the individual states Z1, Z2a, Z2b, Z3a, Z3b, Z3c, Z3d, Z4a, Z4b, Z4c, Z4d, Z5a, Z5b, Z5c, Z5d, Z5e and End states EZ1, EZ2, EZ3, EZ4, EZ5 are assigned. The illustrated functional linkage can be referred to as a so-called model-view-controller link. In this case, the evaluation means 2 the controller, the first storage device 6 the model and the second storage device 7 the view part.

In 5 is an exemplary representation of a touch screen 4 shown. The touch screen 4 this includes an edge 11 , where on the edge so-called hardkeys 12 are arranged. The hardkeys 12 are tactile actuated. On a display device 8th , For example, a display, this can in an image area 13 a picture and in other areas virtual controls 14 are displayed. The virtual controls 14 in this case take a predetermined portion of the display device 8th one. In 5 are exemplary a first virtual control 14-1 , a second virtual control 14-2 , a third virtual control 14-3 , a fourth virtual control 14-4 and a fifth virtual control 14-5 shown. By means of an actuation, for example a touch, of the touchscreen 4 in the area of virtual controls 14 this can be a user input. Will the touch screen 4 for example, in the area of the first virtual control element 14-1 touched, such an operation can be evaluated and compared with predetermined user inputs. This can be done by touching the touchscreen 4 in the area of the first virtual control element 14-1 User input entered match a predetermined user input, so that a transition condition for a change from the current state is met in a subsequent state. Consequently, the system changes to the corresponding subsequent state and outputs the corresponding status information. For example, in the subsequent state, another image in the image area 13 on the display device 8th being represented.

In 6 is another schematic layout of a display device 8th a z. In 5 displayed touch screens 4 shown. This is on the display device 8th For example, a display, an image area 13 intended. In the picture area 13 Here, a visual state information can be displayed. Next are on the display device 8th virtual controls 14 arranged. One by touching a touch screen in the area of the sixth virtual control 14-6 Upon successful user input, a predetermined user input of a transient condition associated with a return operation is detected. Analog is when pressing the touch screen 4 in the range of a seventh virtual control element 14-7 a user input corresponding to a predetermined user input, the one Transition condition for a change to a help state HZ (see 2 ) Fulfills. When the touchscreen is operated 4 in the range of an eighth virtual control element 14-8 a user input corresponding to a predetermined user input satisfying a transition condition for a change to a retry state is detected, wherein in the retry state, a repetitive issuance of status information of the current state, such as a reissue of audible state information, occurs. Will the touch screen 4 in an area of one of the other virtual controls 14-9 actuated, this results in a user input, which corresponds to a predetermined user input of a transition condition for a change to further predetermined sequence states of the current state.
