Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001 .

Those skilled in the art can understand that the structure shown in FIG. 1 does not constitute a limitation to the car locking device, and may include more or less components than shown in the figure, or combine some components, or arrange different components.

As shown in FIG. 1 , the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module and a car lock program.

In the car lock device shown in Figure 1, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the car lock device of the present invention can be It is set in the car locking device, and the car locking device invokes the car locking program stored in the memory 1005 through the processor 1001, and executes the car locking method provided by the embodiment of the present invention.

An embodiment of the present invention provides a method for locking a car. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a first embodiment of the method for locking a car according to the present invention.

In this embodiment, the method for locking the car includes the following steps:

Step S10: When the vehicle lock command is received, inquire about the status of the vehicle lock terminal according to the vehicle lock command.

It should be noted that the execution subject of this embodiment is the car locking device, such as: T-BOX, server, computer, vehicle-mounted computer, etc., and it can also be other devices that can realize the same or similar functions, and this embodiment does not limit this , this embodiment takes the car locking device as an example for illustration.

In a specific implementation, the vehicle lock instruction may be a vehicle lock instruction generated by a vehicle management center or a user sending a vehicle lock request. And send the car locking instruction to the Internet of Vehicles platform. The Internet of Vehicles platform may be a commercial vehicle Internet of Vehicles platform, which is not limited in this embodiment. When the car networking platform receives the car lock command, it queries the status of the car lock terminal according to the car lock command, so as to determine whether the networking status of the car lock terminal is normal.

It should be understood that the state of the lock terminal refers to the state of the IVT. After receiving the lock command, the state of the IVT of the vehicle can be queried. The state of the IVT includes the normal network state, the offline state, and the removed state. There is no limit to this.

Step S20: Obtain the engine state when the state of the lock terminal is normal.

In this embodiment, the normal state of the locking terminal refers to the normal state of the IVT networking, including the normal networking between the Internet of Vehicles platform and the IVT, the normal networking between the IVT and the engine, and the normal connection of the CAN (Controller Area Network, controller area network) bus And the vehicle's antenna connection is normal.

It should be noted that when the lock terminal is in normal state, the vehicle can be actively locked or unlocked. The active lock of the vehicle includes the active lock of the open lock and the active lock of the concealed lock. When the engine state of the vehicle Under normal circumstances, the vehicle can be locked and actively locked, so as to complete the active locking of the vehicle. When the engine state of the vehicle is abnormal, for example, when the engine is maliciously stolen, the active lock of the open lock will fail, and the vehicle may have a safety risk. The vehicle can be locked and actively locked to ensure the safety of the vehicle, so the engine state can be obtained, thereby Determine whether the vehicle needs to be actively locked with an open lock or an active lock with a concealed lock.

Further, the state of the engine includes a normal state of the engine and an abnormal state of the engine, and the step after obtaining the state of the engine further includes: when the state of the engine is normal, generating an open lock state inquiry command to the lock terminal; receiving the lock The open lock state fed back by the car terminal; when the open lock state is activated, generate an open lock active lock command to the lock terminal, so that the lock terminal can pass the open lock active lock command based on the open lock The preset locking protocol implements open locking and active locking on the vehicle.

It can be understood that when the engine state is obtained to be normal, it means that the user's car locking requirement can be realized by only performing an open and active locking of the vehicle at this time. When the vehicle is locked with an open lock, it is necessary to query the state of the open lock. The Internet of Vehicles platform invents the query command for the lock state of the vehicle according to the received lock command and sends it to the vehicle's lock terminal. The lock terminal locks the vehicle according to the open lock. The state query command queries the activation state of the open lock function of the engine and the locked state of the vehicle. The engine electronic controller will periodically send the engine lock status to the lock terminal, so the lock terminal can directly obtain the engine lock status through the engine electronic controller.

The open lock state refers to the activated state of the open lock function of the engine and the locked state of the engine. After the vehicle network platform receives the open lock status feedback from the lock terminal, it can determine whether the open lock state is activated. When it detects that the open lock state is activated and the engine is not locked, it can generate an open lock active lock command to the lock The car terminal obtains the preset car lock agreement through the car lock terminal according to the open lock active lock command, and performs open lock active lock on the vehicle through the preset lock agreement.

The preset lock agreement refers to the vehicle's private lock agreement, which is applicable to fuel commercial vehicles installed with new national standard recorders, engine electronic controllers and engines that support private lock agreements. When the status of the vehicle's open lock function is not activated, the Internet of Vehicles platform can issue an activation command to the car lock terminal, and the car lock terminal performs a handshake verification with the engine through the activation command to establish a unique binding relationship, and the handshake verification result is a handshake When the verification is successful, the open lock car lock function is activated. After activation, the open lock active lock, the open lock offline lock and the open lock anti-tampering lock can be performed. Corresponding locking and unlocking can be performed by determining the status of the locking terminal. If the status of the lock terminal is normal, the vehicle can be locked and actively locked. It is not possible to use any form of locking function before the locking function of the open lock is activated or after it is turned off.

Step S30: When the state of the engine is abnormal, generate a built-in lock active lock command to the car lock terminal, so that the car lock terminal performs built-in lock active lock on the vehicle according to the built-in lock active lock command.

It should be noted that the abnormal state of the engine means that the engine has been maliciously stolen, and may also be other abnormal states of malicious damage to the engine.

In specific implementation, when the state of the engine is abnormal and the state of the lock terminal is normal, it means that the open lock function has failed at this time, and it is necessary to activate the concealed lock of the vehicle to actively lock the car. When it is necessary to lock the vehicle with a built-in lock, it is necessary to determine the built-in lock status of the vehicle first. Therefore, the Internet of Vehicles platform sends a built-in lock status query command to the car lock terminal. After receiving the built-in lock status query command, the car lock terminal sends a query command to the vehicle body The controller and the vehicle body controller inquire about the activation status of the built-in lock function and the car lock status to the car lock terminal. When the built-in lock function is not activated, the Internet of Vehicles platform sends a hidden lock activation command to the car lock terminal, and the car lock terminal receives the built-in lock activation. After the command, shake hands with the body controller to verify the establishment of a unique binding relationship, activate the built-in lock function, so as to actively lock the vehicle through the lock terminal, and trigger the built-in lock offline lock when other lock conditions are met. car or built-in anti-tamper lock car.

Further, after the vehicle is locked, the locked state of the vehicle can also be obtained; the locked state can be marked to trace back the locked vehicle.

It should be noted that when the Internet of Vehicles platform determines that the vehicle is about to be locked or has already occurred, it can obtain the vehicle's locked status, and can mark the vehicle's locked status through the vehicle's lock warning and lock alarm functions. Problems can also be marked according to the lock status of the vehicle, and information such as the lock status of the vehicle and the trigger and release of the lock can be recorded, so that the vehicle can be retroactively locked according to the lock status to reduce the proportion of accidental locks.

In this embodiment, when the lock command is received, the lock terminal status of the vehicle is inquired according to the lock command; when the lock terminal status is normal, the engine status is acquired; when the engine status is abnormal, a built-in lock is generated The active lock command is sent to the lock terminal, so that the lock terminal can perform concealed lock and active lock on the vehicle according to the concealed lock active lock command, and the vehicle's built-in lock can be used to actively lock the vehicle when an abnormal situation occurs in the engine , to upgrade the locking function of the vehicle and improve the safety of the vehicle.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a second embodiment of the method for locking a car according to the present invention.

Based on the above-mentioned first embodiment, the step S10 of the method for locking the car in this embodiment specifically includes:

Step S101: When a car lock command is received, query the network status, CAN bus status and antenna status of the car lock terminal according to the car lock command.

It should be noted that the state of the car locking terminal includes the networking state of the car locking terminal, the state of the CAN bus of the vehicle, and the state of the antenna of the vehicle. The networking status of the car lock terminal includes the networking status of the car locking terminal and the car networking platform and the networking status of the car locking terminal and the engine, the CAN bus status includes CAN bus connection and CAN bus removal, and the antenna status includes antenna connection and antenna removal.

Step S102: Obtain the status of the vehicle locking terminal according to the networking status of the locking terminal, the status of the CAN bus and the status of the antenna.

In a specific implementation, after acquiring the networking status, CAN bus status and antenna status of the car locking terminal, the status of the vehicle locking terminal can be determined according to the networking status, CAN bus status and antenna status of the car locking terminal. For example, if the networking status of the car lock terminal is normal, the CAN bus status is CAN bus connection, and the antenna status is antenna connection, then the car lock terminal status is normal. If the network status of the car lock terminal is abnormal, the status of the CAN bus is CAN bus connection, and the status of the antenna is that the antenna is removed, then the status of the car lock terminal is that the car lock terminal is offline. If the networking status of the car lock terminal is abnormal, the CAN bus is removed, and the antenna is removed, the state of the car lock terminal is that the car lock terminal is in a removed state. Therefore, different types of car locking can be performed according to the state of the car locking terminal.

In this embodiment, when a car lock command is received, query the network status, CAN bus status and antenna status of the car lock terminal according to the car lock command; according to the network status of the car lock terminal, the CAN bus status and the The state of the above antenna is used to obtain the state of the lock terminal of the vehicle. The vehicle can be quickly locked according to the status of the locking terminal, covering various locking scenarios of the vehicle, and further improving the safety of the vehicle and the user experience.

Referring to FIG. 4 , FIG. 4 is a schematic flow chart of a third embodiment of the vehicle locking method of the present invention.

Based on the first and second embodiments above, the method for locking the car in this embodiment, after the step S10, further includes:

Step S11: determining that the car locking terminal is in an offline state when the networking status of the car locking terminal is abnormal, the CAN bus is normal, and the antenna is removed.

It should be noted that when the network status of the car lock terminal is abnormal, the CAN bus is normal and the antenna is removed, the car lock terminal cannot be connected to the Internet of Vehicles platform, so it is determined that the car lock terminal is offline.

Step S12: Obtain the engine status and the offline time of the lock terminal.

In the specific implementation, when the car lock terminal is in the offline state, it can be further determined whether the car lock terminal is maliciously offline, then it can be determined by the offline time of the car lock terminal, and obtain the engine state to determine whether the engine is abnormal, so as to determine whether the vehicle is abnormal. Use an open lock or a concealed lock to lock the car.

Step S13: When the state of the engine is abnormal and the offline time of the lock terminal exceeds the preset offline time, generate an open lock offline lock command to the engine, so that the engine passes through the open lock offline lock command based on the open lock offline lock command. The preset lock protocol performs open lock and offline lock on the vehicle.

It should be noted that the preset offline time can be set according to user requirements or vehicle models, such as 15 days, 20 days, 30 days, etc. This embodiment does not limit this, and this embodiment uses 30 days as an example for illustration.

It should be understood that when the offline time of the car lock terminal exceeds the preset offline time, it is determined that the car lock terminal has been maliciously operated offline, and therefore the vehicle needs to be locked offline. The specific type of offline lock can be determined by determining the engine status. When the state of the engine is normal, the car lock terminal sends an instruction to the electronic controller of the vehicle engine to invent and lock the car offline, trigger the car to lock the car offline, and lock the car through a private protocol. When the car lock terminal and the Internet of Vehicles platform After the connection of the car is restored, the lock terminal can send an unlock command to Fadong to unlock it.

When the state of the engine is abnormal and the offline time of the lock terminal exceeds the preset offline time, it is necessary to carry out both the open lock offline lock and the hidden lock offline lock on the vehicle at the same time, and the hidden lock offline lock on the basis of the open lock offline lock. Generate an open lock offline lock command to the engine electronic controller, and the electronic controller controls the engine to perform open lock offline lock on the vehicle with a private lock protocol.

Step S14: Generate a built-in offline lock command to the body controller of the vehicle, so that the body controller performs a built-in offline lock on the vehicle through a torque request message based on the built-in offline lock command.

It should be noted that the torque request message refers to a message that limits the engine torque or speed, and the torque request message can be a TSC1 message, and the TSC1 message is the "SAEJ1939-71 Commercial Vehicle Control System Local Area Network (CAN Bus) Communication Protocol". General messages applicable to commercial vehicles defined in Part 5 Application Layer—Vehicles. While generating the open lock offline lock command, the lock terminal also sends a hidden lock offline lock command to the body controller. After receiving the built-in lock offline lock command, the body controller sends a torque request message to the vehicle engine to Carry out built-in lock to lock the car offline.

In this embodiment, when the networking status of the car-locking terminal is abnormal, the CAN bus is normal, and the antenna is removed, it is determined that the car-locking terminal is in an offline state; the engine state and the offline time of the car-locking terminal are acquired ; When the state of the engine is abnormal and the offline time of the lock terminal exceeds the preset offline time, generate an open lock offline lock command to the engine, so that the engine passes the preset time based on the open lock offline lock command The car locking protocol performs open locking and offline locking on the vehicle; generates a built-in lock offline lock command to the vehicle body controller, so that the body controller transmits a torque request message to the vehicle body controller based on the built-in lock offline lock command. The vehicle is locked offline with a built-in lock. When the locking terminal is abnormally connected to the network and the engine is abnormal, the vehicle can be locked offline with an open lock and an offline lock with a built-in lock at the same time. By double locking the vehicle, the safety of the vehicle is improved.

Referring to FIG. 5 , FIG. 5 is a schematic flowchart of a fourth embodiment of the method for locking a car according to the present invention.

Based on the first and second embodiments above, the method for locking the car in this embodiment, after the step S10, further includes:

Step S11 _' : When the networking state of the car-locking terminal is abnormal, the CAN bus is removed, and the antenna is removed, determine that the car-locking terminal is in a state of being removed.

It should be noted that when the networking status of the car lock terminal is abnormal, the CAN bus and the antenna are removed, it is determined that the car lock terminal is in the removed state.

Step S12': Obtain the handshake verification result and engine status between the engine and the car lock terminal.

In a specific implementation, when the car lock terminal is removed, the engine may not be able to receive the command issued by the car lock terminal, so it is necessary to obtain the handshake verification result between the engine and the car lock terminal and the state of the engine. When the handshake verification result between the engine and the car lock terminal is a successful handshake, it proves that the command issued by the car lock terminal can be received by the engine, and the car lock terminal has not been removed.

Step S13': When the result of the handshake verification is that the handshake fails and the state of the engine is abnormal, generate an open lock anti-tamper and locked car command and a hidden lock anti-tamper locked car command.

When the handshake verification result shows that the handshake fails, it means that the car lock terminal has been dismantled, so the car needs to be tamper-proof, which can include open-lock anti-tamper lock cars and concealed lock anti-tamper-lock cars, which can be selected according to the engine status. When the engine is in a normal state, only the vehicle can be unlocked and anti-tampered, so the engine itself generates an instruction for anti-tampering, and in the next power-on cycle, it will perform an anti-tampering lock through the private locking protocol, triggering The condition is that in this power-on cycle, if the lock terminal is detected to be dismantled, the lock will be triggered in the next power-on cycle to limit the speed and torque of the engine. When the engine electronic controller and the lock When the terminal handshake verification result is a successful handshake, the engine will automatically release the state of limiting torque and speed, and release the open lock anti-tampering lock.

Step S14 _′ : Limiting the rotational speed and torque of the engine according to the open-lock anti-tamper-lock vehicle command, so as to realize the open-lock anti-tamper-lock vehicle of the vehicle.

When the state of the engine is abnormal, it is necessary to trigger both the anti-tampering lock car with the lock and the car with the anti-tamper lock A power-on cycle uses a private car lock protocol to lock the car with anti-tampering.

Step S15': Obtain a torque request message according to the built-in lock anti-tamper lock command, and limit the speed and torque of the engine according to the torque request message, so as to realize the built-in lock anti-tamper lock of the vehicle .

In this embodiment, the engine obtains the torque request message through the built-in lock anti-tamper lock command, and obtains a specific limit on the number of revolutions of the engine, such as 1000 revolutions. The torque request message is used to limit the speed of the engine to 1000 revolutions, and limit the engine torque.

Specifically, the step of performing built-in lock and anti-tamper locking on the vehicle includes: obtaining a torque request message according to the command of the built-in lock and anti-tamper lock when no feedback information from the lock terminal is detected within the preset power-on period ; Limiting the rotational speed and torque of the engine according to the torque request message.

It should be understood that the preset power-on cycle can be set according to requirements, for example, 3 power-on cycles, 4 power-on cycles, etc., and this embodiment uses 3 power-on cycles as an example for illustration. The condition for triggering the built-in lock and anti-tampering locked car is that the engine electronic controller cannot obtain the feedback information from the car-locking terminal within 3 consecutive power-on cycles, then in the next power-on cycle, a torque request message is generated according to the built-in lock anti-tampering and locked car command, And send the torque request message to the engine, so as to control the speed limit and torque limit of the engine.

Specifically, after obtaining the torque request message according to the built-in lock anti-tampering and locking the car instruction, and limiting the engine speed and torque according to the torque request message, it also includes: after detecting the locked car When the feedback information is received from the terminal, an instruction to release the anti-tamper lock vehicle is generated; according to the instruction to release the anti-tamper lock vehicle, the built-in lock anti-tamper lock vehicle is released for the vehicle.

When the engine electronic controller re-monitors the feedback information from the lock terminal, it can generate an anti-tamper lock command to unlock the vehicle.

As shown in FIG. 6 , FIG. 6 is a functional framework diagram of an open-lock car lock in this embodiment. It is divided into open lock active car lock, open lock offline car lock and open lock anti-tamper lock car. When the status of the lock terminal is normal, the initiator of the lock is the Internet of Vehicles platform, and the active lock command is sent to the IVT through the Internet of Vehicles platform, and the vehicle is actively locked through the communication between the IVT and the engine. When the state of the lock terminal is offline, the initiator of the lock is IVT, and the offline lock command is sent to the engine through the IVT, so that the vehicle can be locked and locked offline. When the locked car terminal is in the dismantled state, the initiator of the locked car is the engine, which controls its own torque and speed through the transmitter to realize the open lock and anti-tamper lock of the vehicle.

As shown in FIG. 7 , FIG. 7 is a functional architecture diagram of the built-in lock and car lock in this embodiment. Built-in lock car locks are divided into built-in lock automatic lock car, built-in lock offline car lock and built-in lock anti-dismantle lock car. When the state of the lock terminal is normal and the state of the engine is abnormal, the initiator of the lock is the Internet of Vehicles platform, which sends the hidden lock active lock command to the IVT through the Internet of Vehicles platform, and transmits it to the body controller through the IVT, and then through the BCM (body controller) Control the vehicle engine, so as to realize the active locking of the vehicle. When the car lock terminal is offline and the engine status is abnormal, the car lock initiator is IVT, which sends the built-in lock offline lock command to the body controller through IVT, and controls the vehicle engine through the body controller to realize the built-in lock offline lock of the vehicle.
