[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0051] Furthermore, in this document, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0052] As can be seen from the background technology, in order to monitor the vehicle data and transmit the data to the cloud platform, a vehicle terminal needs to be installed on the vehicle, and the user can also issue relevant instructions such as locking the vehicle to the vehicle terminal through the cloud platform. However, if the vehicle terminal is illegally removed, the vehicle will not be able to be remotely controlled, which brings certain safety hazards.

[0053] In view of this, the present application provides a vehicle control method, device, electronic device and storage medium to solve the above problems.

[0054] The present application embodiment provides a vehicle control method, such as Figure 1 As shown, specifically including:

[0055] S101. When a vehicle controller is powered on, determine a vehicle lock state; wherein the vehicle lock state includes a vehicle lock activated state and a vehicle lock inactivated state.

[0056] It should be noted that when the vehicle controller is powered on, it first determines whether the vehicle lock state is activated. If the vehicle lock is activated, the subsequent terminal anti-disassembly verification is performed. If the vehicle lock is not activated, the terminal anti-disassembly verification is not performed. The terminal refers to the vehicle-mounted Internet of Vehicles terminal, which is a vehicle-mounted device installed on the vehicle to monitor data and transmit data to the platform.

[0057] Optionally, in another embodiment of the present application, an implementation of the above step S101 may include:

[0058] Obtain the vehicle's locking parameters; wherein the locking parameters are generated by the main processor according to user instructions; the main processor is used to communicate with the cloud platform.

[0059] The vehicle locking state is determined according to the vehicle locking parameters.

[0060] It should be noted that the vehicle's locking parameters are first obtained, where the locking parameters are generated by the main processor according to user instructions, including the locking activation status, CAN bus communication baud rate, anti-dismantling handshake message ID, etc. The locking function is activated by the user, and the main processor establishes a connection with the management platform (cloud platform). When the user issues a locking instruction through the management platform, the main processor can receive the locking instruction from the management platform, execute the locking operation and generate the locking parameters. The main processor then sends the locking parameters to the coprocessor, and the coprocessor updates the locking parameters and stores them. The main processor and the coprocessor are processors of the vehicle terminal, and a communication connection is established in advance between the main processor and the coprocessor.

[0061] After the vehicle locking parameters are obtained, it is determined whether the vehicle locking state is activated according to the vehicle locking activation state information in the vehicle locking parameters.

[0062] S102: If the vehicle is in a locked state, a terminal anti-disassembly verification is performed on the vehicle through a coprocessor; wherein the coprocessor is used to execute a terminal anti-disassembly verification algorithm.

[0063] It should be noted that if it is determined that the vehicle is in the locked state, the terminal anti-disassembly verification is performed by sending verification information to the coprocessor to determine whether there is an abnormality in the vehicle terminal. Among them, since the current vehicle terminal adopts an operating system-based development architecture to expand functions and improve performance, the startup time is long and it is difficult to quickly respond to the anti-disassembly verification. Therefore, a coprocessor is used to execute the terminal anti-disassembly verification algorithm. There is no need to wait for the vehicle terminal to start the system. The locking function is split by using the fast startup characteristics of the coprocessor, which can quickly complete the terminal anti-disassembly verification and coordinate with the main processor to achieve vehicle control.

[0064] Optionally, in another embodiment of the present application, an implementation of the above step S102 is as follows: Figure 2 As shown, this may include:

[0065] S201, sending a message carrying an anti-tampering handshake code to a coprocessor via a communication bus to trigger the coprocessor to calculate an anti-tampering response code according to the anti-tampering handshake code.

[0066] It should be noted that the vehicle controller sends a message carrying the anti-tamper handshake code to the coprocessor via the CAN (Controller Area Network) communication bus. After receiving the message, the coprocessor calculates the anti-tamper response code based on the anti-tamper handshake code and sends it to the vehicle controller.

[0067] S202: If the anti-tampering response code sent by the coprocessor is not received within the preset time, the terminal anti-tampering verification fails.

[0068] It should be noted that if the anti-disassembly response code sent by the coprocessor is not received within the preset time, it is likely that the vehicle terminal has been disassembled, resulting in the coprocessor being unresponsive and unable to send the anti-disassembly response code, so the terminal anti-disassembly verification fails. The preset time can be set according to actual conditions, for example, 1 minute.

[0069] S203: If the anti-tampering response code sent by the coprocessor is received within a preset time, the correctness of the anti-tampering response code is verified.

[0070] It should be noted that if the anti-tampering response code sent by the coprocessor is received within the preset time, the correctness of the anti-tampering response code is verified, wherein the anti-tampering response code is verified by checking whether the serial number carried in the anti-tampering response code is consistent with the expected one. If they are consistent, the anti-tampering response code is correct; if they are inconsistent, the anti-tampering response code is incorrect.

[0071] S204: If the anti-tamper response code is correct, the terminal anti-tamper verification passes.

[0072] S205: If the anti-tamper response code is incorrect, the terminal anti-tamper verification fails.

[0073] S103: If the terminal anti-disassembly verification fails, the vehicle is restricted according to a preset restriction strategy.

[0074] It should be noted that if the anti-disassembly check of the vehicle terminal fails, it means that there is an abnormality in the vehicle terminal and it may have been illegally disassembled. Therefore, the vehicle is restricted according to the preset restriction strategy to prevent the vehicle from being maliciously disassembled and then stolen. The restriction strategy can be set according to actual needs, such as limiting power.

[0075] Optionally, in another embodiment of the present application, an implementation of step S103 may include:

[0076] When the reason why the terminal anti-tampering check fails is that the anti-tampering response code sent by the coprocessor is not received within the preset time, the engine start is restricted.

[0077] When the reason why the terminal anti-tampering verification fails is that the anti-tampering response code is incorrect, the engine speed and torque are limited according to the preset limit values.

[0078] It should be noted that if the reason why the terminal anti-dismantling check fails is that the anti-dismantling response code sent by the coprocessor is not received within the preset time, the coprocessor can no longer respond at this time, and it is very likely that the vehicle-mounted terminal has been dismantled. Therefore, the engine start-up is restricted to prevent the vehicle from continuing to drive, causing losses to the owner.

[0079] If the reason why the terminal anti-tampering verification fails is that the anti-tampering response code is incorrect, and the coprocessor is responsive at this time, it is possible that the coprocessor or the entire vehicle terminal is abnormal due to some reasons, causing the calculated anti-tampering response code to be incorrect. Therefore, the engine speed and torque are limited only according to the preset limit values, such as the engine speed is limited to 1500 rpm and the engine torque is limited to 100Nm. If the verification is normal later, the limit will be lifted.

[0080] In a vehicle control method provided by an embodiment of the present application, when the controller is powered on, the vehicle lock state is determined; wherein, the vehicle lock state includes a vehicle lock activated state and a vehicle lock inactivated state. If the vehicle is in the vehicle lock activated state, the terminal anti-dismantling check is performed on the vehicle through the coprocessor; wherein, the coprocessor is used to execute the terminal anti-dismantling check algorithm. If the terminal anti-dismantling check fails, the vehicle is restricted according to the preset restriction policy. It can be seen that, using the method of the present application, after each power-on of the controller, if the vehicle is in the vehicle lock activated state, the terminal anti-dismantling check is performed on the vehicle through the coprocessor. The coprocessor is specifically used to execute the terminal anti-dismantling check algorithm, has a fast startup, and can quickly complete the terminal anti-dismantling check. If the anti-dismantling check fails, the vehicle is restricted according to the preset restriction policy to prevent the vehicle from being out of control after the terminal is illegally disassembled, causing losses to the user.

[0081] Another embodiment of the present application also discloses a vehicle control device, such as Figure 3 As shown, specifically including:

[0082] The determination unit 301 is used to determine the vehicle lock state when the vehicle controller is powered on; wherein the vehicle lock state includes a vehicle lock activated state and a vehicle lock inactivated state.

[0083] The verification unit 302 is used to perform terminal anti-disassembly verification on the vehicle through a coprocessor if the vehicle is in a locked state; wherein the coprocessor is used to execute a terminal anti-disassembly verification algorithm.

[0084] The restriction unit 303 is used to restrict the vehicle according to a preset restriction strategy if the terminal anti-disassembly verification fails.

[0085] In this embodiment, the specific execution process of the determination unit 301, the verification unit 302 and the restriction unit 303 can be found in the corresponding Figure 1 The content of the method embodiment will not be repeated here.

[0086] In a vehicle control device provided by an embodiment of the present application, when the controller is powered on, the determination unit 301 determines the vehicle lock state; wherein the vehicle lock state includes the vehicle lock activated state and the vehicle lock inactivated state. If the vehicle is in the vehicle lock activated state, the verification unit 302 performs terminal anti-disassembly verification on the vehicle through the coprocessor; wherein the coprocessor is used to execute the terminal anti-disassembly verification algorithm. If the terminal anti-disassembly verification fails, the restriction unit 303 restricts the vehicle according to the preset restriction strategy. It can be seen that, using the method of the present application, after each power-on of the controller, if the vehicle is in the vehicle lock activated state, the terminal anti-disassembly verification is performed on the vehicle through the coprocessor. The coprocessor is specifically used to execute the terminal anti-disassembly verification algorithm, which starts quickly and can quickly complete the terminal anti-disassembly verification. If the anti-disassembly verification fails, the vehicle is restricted according to the preset restriction strategy to prevent the vehicle from being out of control after the terminal is illegally disassembled, causing losses to the user.
