Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a vehicle locking method, a vehicle locking system and a vehicle. Background Art

[0002] T-BOX is a key component in the Internet of Vehicles system. It is mainly responsible for communicating with the backend system and mobile phone APP to display and control vehicle information. CAN bus It interacts with ECU to realize various functions such as remote control, information monitoring, safety monitoring, remote diagnosis, etc. The existence of T-BOX has greatly enriched the intelligent level of automobiles.

[0003] ECU, as one of the core components of modern automotive electronics, ensures the normal operation of the car. ECU receives and executes control instructions from T-BOX, and may also send vehicle status information to T-BOX so that users or OEMs can obtain vehicle information.

[0004] In order to meet the requirements of regulations (such as environmental protection requirements and safety requirements, etc.), T-BOX and ECU are prohibited from privately changing models that are not registered with the manufacturer, and are prohibited from modifying internal programs. However, after the vehicle is sold to the market, there are consumers who privately tamper with the vehicle data. For example, the regulations require that the engine emission standards of National IV vehicles meet certain environmental protection requirements, but some customers have tampered with the engine programs of some vehicles in order to reduce maintenance costs and reduce fuel consumption and other related factors. This has caused the OEM to be in a relatively passive situation.

[0005] To avoid this phenomenon, OEMs usually lock vehicles that have been replaced with unregistered T-BOX and ECUs or have modified internal programs without permission. The specific operation is that the vehicle lock management system sends a lock command to the ECU through the T-BOX to achieve remote vehicle lock. However, if the replaced ECU itself does not have the lock and unlock functions, the OEM cannot lock the vehicle.

[0006] Therefore, a vehicle locking method is urgently needed to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a vehicle locking method, a vehicle locking system and a vehicle, so as to solve the problem in the related art that when the replaced ECU itself does not have the locking and unlocking functions, the main engine manufacturer cannot lock the vehicle.

[0008] On the one hand, the present invention provides a vehicle locking method, which is implemented by a vehicle locking system, wherein the vehicle locking system includes a TBOX, an ECU, a vehicle locking management module, and a power distribution management module. The vehicle locking method includes:

[0014] S50: Determine whether the vehicle is in a locked state, if yes, execute S60, if no, execute S40;

[0015] S60: Maintaining the current state of the entire vehicle.

[0016] As a preferred technical solution for the vehicle locking method, S30 specifically includes:

[0017] S301: whether the TBOX has issued a vehicle locking instruction, if yes, execute S302, if no, execute S40;

[0018] S302: Whether the ECU feeds back the execution result of the vehicle locking instruction to the TBOX, if yes, then execute S50, if no, then execute S40.

[0019] As a preferred technical solution of the vehicle locking method, the vehicle locking instruction is that the ECU controls the vehicle engine to remain in a stopped state.

[0020] As a preferred technical solution of the vehicle locking method, S50 specifically includes determining whether the vehicle engine can run, and if so, executing S40, and if not, executing S60.

[0021] As a preferred technical solution of the vehicle locking method, before executing S10, it also includes: S01: determining whether the TBOX and / or the ECU are offline; if yes, executing S02, if not, executing S60;

[0022] S02: Determine whether the version and internal program information of the TBOX and / or the ECU are illegally changed. If yes, execute S10; if not, execute S60.

[0023] As a preferred technical solution for the vehicle locking method, S02 specifically includes:

[0024] S021: Determine whether the version information of the TBOX and / or the ECU is consistent with the version information filed on the Internet of Vehicles platform. If yes, execute S022; if not, execute S10;

[0025] S022: Determine whether the internal program information of the TBOX and / or the ECU is consistent with the program information filed on the Internet of Vehicles platform. If yes, execute S60; if not, execute S10.

[0026] On the other hand, the present invention provides a vehicle locking system, which is implemented by the vehicle locking method in any of the above-mentioned schemes, including the TBOX, the ECU, the vehicle locking management module and the power distribution management module, the TBOX, the ECU and the power distribution management module are communicatively connected in pairs via a CAN network, the vehicle locking management module is communicatively connected to the TBOX via the CAN network, and the power distribution management module can actively control the power supply of the entire vehicle electrical equipment.

[0027] As a preferred technical solution of the vehicle locking system, the vehicle locking system further includes an offline detection module, and the offline detection module is used to monitor whether the TBOX and / or the ECU is offline.

[0028] In yet another aspect, the present invention provides a vehicle, comprising the vehicle locking system in any of the above schemes.

[0029] The beneficial effects of the present invention are:

[0030] The present invention provides a vehicle locking method, a vehicle locking system and a vehicle, which are implemented through the vehicle locking system. The vehicle locking system includes a TBOX, an ECU, a vehicle locking management module and a power distribution management module. The vehicle locking method includes: S10: the vehicle locking management module sends a vehicle locking instruction to the ECU through the TBOX; S20: the power distribution management module monitors the instruction interaction process between the TBOX and the ECU; S30: judging whether there is an abnormality in the instruction interaction process between the TBOX and the ECU, if yes, executing S40; S40: the power distribution management module controls the power-off of the electrical equipment of the whole vehicle. When the vehicle's TBOX and / or ECU are illegally changed or unregistered programs are illegally written, the vehicle lock management module sends a vehicle lock command to the ECU through the TBOX, thereby commanding the entire vehicle to enter the locked state. However, when the TBOX and / or ECU that are illegally changed or unregistered programs are illegally written do not have the vehicle lock function, at this time, the instruction interaction process between the TBOX and the ECU is abnormal. Therefore, when the power distribution management module detects that the instruction interaction process between the TBOX and the ECU is abnormal, the entire vehicle's electrical equipment can be directly controlled to cut off power. At this time, the vehicle cannot work normally, and the vehicle enters the locked state. This vehicle locking method solves the problem that when the replaced ECU and / or TBOX itself does not have the locking and unlocking functions, the OEM cannot lock the vehicle.

[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a vehicle locking method, which is implemented by a vehicle locking system.

[0040] Specifically, the vehicle locking system includes TBOX1, ECU2, a locking management module 3 and a power distribution management module 4. TBOX1, ECU2 and the power distribution management module 4 are connected in pairs through the CAN network. The locking management module 3 is connected to TBOX1 through the CAN network, and the power distribution management module 4 can actively control the power supply of the vehicle electrical equipment 5. In this embodiment, the issuance and feedback of instructions can be realized between TBOX1 and ECU2 through the CAN network. The power distribution management module 4 can detect whether there is an abnormality in the instruction interaction process between TBOX1 and ECU2. At the same time, the power distribution management module 4 can actively control the power supply of the vehicle electrical equipment 5. The locking management module 3 can send a locking instruction to ECU2 through TBOX1.

[0041] Optionally, the vehicle locking system further includes an offline detection module, which is used to monitor whether TBOX1 and / or ECU2 are offline. In this embodiment, when TBOX1 and / or ECU2 are replaced or written with a program, TBOX1 and / or ECU2 need to be powered off, at which time, the offline detection module can monitor whether TBOX1 and / or ECU2 are offline.

[0042] Vehicle locking methods include:

[0043] S01: Determine whether TBOX1 and / or ECU2 are offline; if yes, execute S02; if no, execute S60.

[0044] In this step, when TBOX1 and / or ECU2 are replaced or written with a program, TBOX1 and / or ECU2 need to be powered off. At this time, the offline detection module can detect whether TBOX1 and / or ECU2 are offline. If TBOX1 and / or ECU2 are offline, it proves that TBOX1 and / or ECU2 may be replaced or written with a program.

[0045] S02: Determine whether the version and internal program information of TBOX1 and / or ECU2 are illegally changed. If yes, execute S10; if not, execute S60.

[0046] In this step, it is determined that the version and internal program information of TBOX1 and / or ECU2 are illegally changed, and then S10 is executed to lock the vehicle. When it is determined that the version and internal program information of TBOX1 and / or ECU2 are not illegally changed, the vehicle locking method ends, and the vehicle is kept in the current state.

[0047] Optionally, S02 specifically includes:

[0048] S021: Determine whether the version information of TBOX1 and / or ECU2 is consistent with the version information filed on the Internet of Vehicles platform. If yes, execute S022; if not, execute S10.

[0049] In this step, the version numbers of TBOX1 and / or ECU2 are all registered on the Internet of Vehicles platform. When the version numbers of TBOX1 and / or ECU2 are inconsistent with the version numbers registered on the Internet of Vehicles platform, it means that the vehicle has replaced an illegal TBOX1 and / or ECU2, and then S10 is executed to lock the vehicle. When the version numbers of TBOX1 and / or ECU2 are consistent with the version numbers registered on the Internet of Vehicles platform, S022 is executed.

[0050] S022: Determine whether the internal program information of TBOX1 and / or ECU2 is consistent with the program information filed on the Internet of Vehicles platform. If yes, execute S60; if not, execute S10.

[0051] In this step, the internal program information of TBOX1 and / or ECU2 is filed on the Internet of Vehicles platform. When the internal program information of TBOX1 and / or ECU2 is inconsistent with the internal program information filed on the Internet of Vehicles platform, it means that the vehicle TBOX1 and / or ECU2 has been cracked or illegally written, and then S10 is executed to lock the vehicle. When the internal program information of TBOX1 and / or ECU2 is consistent with the internal program information filed on the Internet of Vehicles platform, the vehicle locking method ends, and the vehicle is kept in the current state.

[0052] S10: The vehicle locking management module 3 sends a vehicle locking instruction to the ECU 2 via the TBOX1.

[0053] In this step, the vehicle locking management module 3 is connected to TBOX1 through CAN network communication. The vehicle locking management module 3 can send a vehicle locking instruction to ECU2 through TBOX1, thereby allowing ECU2 to control the locking of the entire vehicle.

[0054] S20: The power distribution management module 4 monitors the instruction interaction process between TBOX1 and ECU2.

[0055] In this step, the power distribution management module 4 is respectively connected to the TBOX1 and the ECU2 through the CAN network, so as to monitor the instruction interaction process between the TBOX1 and the ECU2 and determine whether the instruction interaction between the TBOX1 and the ECU2 is normal.

[0056] S30: Determine whether there is an abnormality in the instruction interaction process between TBOX1 and ECU2. If yes, execute S40; if no, execute S50;

[0057] In this step, if there is an abnormality in the instruction interaction process between TBOX1 and ECU2, it proves that the locking instruction issued by the locking management module 3 is not transmitted smoothly, resulting in the vehicle being unable to reach the locked state, so S40 needs to be executed. If there is no abnormality in the instruction interaction process between TBOX1 and ECU2, S50 is executed.

[0058] Optionally, S30 specifically includes:

[0059] S301: Has TBOX1 issued a vehicle lock command? If yes, execute S302; if no, execute S40.

[0060] In this step, it is first determined whether TBOX1 has issued a car locking command. If TBOX1 has not issued a car locking command, it indicates that TBOX1 has been illegally replaced or the internal program has been cracked, which in turn causes TBOX1 to be unable to issue a car locking command. Therefore, the car locking management module 3 cannot issue a car locking command to ECU2 through TBOX1, and can only lock the car by executing S40. When TBOX1 normally issues a car locking command, S302 is executed.

[0061] S302: Does ECU2 feed back the execution result of the vehicle locking instruction to TBOX1? If yes, execute S50; if no, execute S40.

[0062] In this step, when TBOX1 does not receive the execution result of the locking command fed back by ECU2, it means that ECU2 has not issued the command to lock the whole vehicle, so S40 is executed to lock the vehicle. When TBOX1 receives the execution result of the locking command fed back by ECU2, it means that ECU2 has issued the command to control the whole vehicle to lock the vehicle.

[0063] S40: The power distribution management module 4 controls the vehicle electrical equipment 5 to cut off power.

[0064] In this embodiment, the power distribution management module 4 controls the electrical equipment 5 of the entire vehicle to cut off the power, thereby achieving the locking of the entire vehicle.

[0065] S50: Determine whether the vehicle is in a locked state. If yes, execute S60; if not, execute S40.

[0066] In this step, the vehicle locking instruction is that ECU2 controls the vehicle engine to remain in a stopped state. S50 specifically includes determining whether the vehicle engine can run. If yes, S40 is executed, and if no, S60 is executed. If it is found that the vehicle engine can still run, it means that the instruction issued by ECU2 to control the vehicle to lock the vehicle has not been executed (the specific reason may be a program error or a failure of the actuator that performs the locking operation, etc.). At this time, S40 is executed to ensure that the vehicle is in a locked state.

[0067] S60: Maintain the current status of the vehicle.

[0068] When the vehicle's TBOX1 and / or ECU2 are illegally changed or illegally written with unregistered programs, the vehicle lock management module 3 sends a vehicle lock command to ECU2 through TBOX1, thereby commanding the entire vehicle to enter a locked state. However, when the TBOX1 and / or ECU2 that are illegally changed or illegally written with unregistered programs do not have the vehicle lock function, at this time, there is an abnormality in the instruction interaction process between TBOX1 and ECU2. Therefore, when the power distribution management module 4 detects that there is an abnormality in the instruction interaction process between TBOX1 and ECU2, the entire vehicle electrical equipment 5 can be directly controlled to cut off power. At this time, the vehicle cannot work normally, and then the vehicle enters a locked state. The vehicle locking method solves the problem that when the replaced ECU2 and / or TBOX1 itself does not have the vehicle lock and unlock functions, the main engine manufacturer cannot lock the vehicle.

[0069] This embodiment also provides a vehicle, including the vehicle locking system in the above solution.

[0070] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
