Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, 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, responsible for communicating with the backend system and mobile phone APP to display and control vehicle information. CAN bus By interacting with the ECU, T-BOX can realize various functions such as remote vehicle control, information monitoring, safety monitoring, and remote diagnosis. The existence of T-BOX has greatly enriched the level of automobile intelligence.

[0003] ECUs, as one of the core components of modern automotive electronics, ensure the normal operation of the vehicle. ECUs receive and execute control commands from the T-BOX and may also send vehicle status information to the T-BOX so that users or OEMs can obtain vehicle information.

[0004] To meet regulatory requirements (such as environmental and safety requirements), T-BOX and ECU models must not be replaced with models not registered with the manufacturer, and internal program modifications are prohibited. However, after vehicles are released to the market, there are cases of consumers tampering with vehicle data. For example, while regulations require that engine emissions standards for China IV vehicles meet certain environmental requirements, some customers, motivated by factors such as reducing maintenance costs and lowering fuel consumption, have tampered with the engine programs of some vehicles. This has left OEMs in a difficult position.

[0005] To prevent this, OEMs typically lock vehicles if they've privately replaced the T-BOX and ECU with unregistered features, or if they've modified internal programs. Specifically, the vehicle lock management system sends a lock command to the ECU via the T-BOX, enabling remote locking. However, if the replaced ECU doesn't have 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 OEM is unable to lock the vehicle.

[0008] In one aspect, the present invention provides a vehicle locking method, which is implemented by a 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:

[0009] S10: The vehicle locking management module sends a vehicle locking instruction to the ECU via the TBOX;

[0010] S20: The power distribution management module monitors the instruction interaction process between the TBOX and the ECU;

[0012] S40: The power distribution management module controls the electrical equipment of the entire vehicle to be powered off.

[0013] As a preferred technical solution of the vehicle locking method, S30 further includes: if there is no abnormality in the instruction interaction process between the TBOX and the ECU, executing S50;

[0014] S50: Determine whether the vehicle is in a locked state. If yes, execute S60; if not, execute S40;

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

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

[0017] S301: Has the TBOX issued a vehicle lock command? If yes, execute S302; if not, execute S40;

[0018] S302: Does the ECU feed back the execution result of the vehicle locking instruction to the TBOX? If yes, execute S50; otherwise, 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 , otherwise, executing S60 .

[0021] As a preferred technical solution of the vehicle locking method, before executing S10, the method further 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 modified. If yes, execute S10; otherwise, 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; otherwise, 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; otherwise, execute S10.

[0026] On the other hand, the present invention provides a vehicle locking system, which is implemented by the vehicle locking method of 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. The power distribution management module can actively control the power supply of the entire vehicle electrical equipment.

[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. The method is implemented by the vehicle locking system, which 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, and if so, executing S40; S40: the power distribution management module controls the power off of the entire vehicle electrical equipment. When a vehicle's TBOX and / or ECU is illegally altered or an unregistered program is illegally written, the vehicle lock management module sends a lock command to the ECU via the TBOX, thereby commanding the entire vehicle to enter the locked state. However, when the TBOX and / or ECU that has been illegally altered or written with an unregistered program does not have the lock function, an anomaly occurs in the command interaction process between the TBOX and ECU. Therefore, when the power distribution management module detects an anomaly in the command interaction process between the TBOX and ECU, it can directly control the power supply to the entire vehicle's electrical equipment, causing the vehicle to be unable to operate normally and enter the locked state. This vehicle locking method solves the problem of the OEM being unable to lock the vehicle when the replaced ECU and / or TBOX itself does not have the lock and unlock functions.

[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed 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 power distribution management module 4 are interconnected via a CAN network. The locking management module 3 communicates with TBOX1 via the CAN network, and the power distribution management module 4 can actively control the power supply to the vehicle's electrical devices 5. In this embodiment, command transmission and feedback can be achieved between TBOX1 and ECU2 via the CAN network. The power distribution management module 4 can detect any anomalies in the command exchange process between TBOX1 and ECU2 and actively control the power supply to the vehicle's electrical devices 5. The locking management module 3 can issue a locking command to ECU2 via TBOX1.

[0041] Optionally, the vehicle locking system further includes an offline detection module configured to monitor whether TBOX1 and / or ECU2 are offline. In this embodiment, when TBOX1 and / or ECU2 are replaced or reprogrammed, they need to be powered off. At this point, 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 not, execute S60.

[0044] In this step, when TBOX1 and / or ECU2 are replaced or reprogrammed, they need to be powered off. At this point, the offline detection module can detect whether TBOX1 and / or ECU2 are offline. If they are, it indicates that TBOX1 and / or ECU2 may have been replaced or reprogrammed.

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

[0046] In this step, it is determined whether the version and internal program information of TBOX1 and / or ECU2 have been illegally modified, and then S10 is executed to lock the vehicle. If it is determined that the version and internal program information of TBOX1 and / or ECU2 have not been illegally modified, the vehicle locking method ends, and the vehicle remains in its 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; otherwise, execute S10.

[0049] In this step, the version numbers of TBOX1 and / or ECU2 are registered on the IoV platform. If the version numbers of TBOX1 and / or ECU2 are inconsistent with the version numbers registered on the IoV platform, it indicates that the vehicle has been replaced with an illegal TBOX1 and / or ECU2, and S10 is then executed to lock the vehicle. If the version numbers of TBOX1 and / or ECU2 are consistent with the version numbers registered on the IoV 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; otherwise, execute S10.

[0051] In this step, the internal program information of TBOX1 and / or ECU2 is registered on the IoV platform. If the internal program information of TBOX1 and / or ECU2 is inconsistent with the registered internal program information on the IoV platform, it indicates that the vehicle's TBOX1 and / or ECU2 has been hacked or illegally written to, and S10 is then executed to lock the vehicle. When the internal program information of TBOX1 and / or ECU2 is consistent with the registered internal program information on the IoV platform, the vehicle locking method ends, and the vehicle remains in its current state.

[0052] S10: The vehicle locking management module 3 sends a vehicle locking instruction to the ECU 2 via the TBOX 1.

[0053] In this step, the vehicle locking management module 3 is connected to the TBOX1 via the CAN network communication. The vehicle locking management module 3 can send a vehicle locking instruction to the ECU2 through the TBOX1, thereby allowing the 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 connected to the TBOX1 and the ECU2 through the CAN network, thereby being able 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 any abnormality in the instruction interaction process between TBOX1 and ECU2. If yes, execute S40; otherwise, execute S50.

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

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

[0061] S302: Does ECU2 feed back the execution result of the vehicle locking instruction to TBOX1? If yes, execute S50; otherwise, execute S40.

[0062] In this step, if TBOX1 does not receive the execution result of the vehicle locking command fed back by ECU2, it means that ECU2 has not issued the instruction to lock the entire vehicle, so S40 is executed to lock the vehicle. If TBOX1 receives the execution result of the vehicle locking command fed back by ECU2, it means that ECU2 has issued the instruction to control the entire 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 power, thereby locking 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 lock command is for ECU2 to control the vehicle engine to remain in a stopped state. S50 specifically determines whether the vehicle engine is operational. If so, S40 is executed; if not, S60 is executed. If the engine is still operational, this indicates that the vehicle lock command issued by ECU2 has not been executed (possibly due to a program error or a malfunction in the actuator that performs the locking operation). In this case, S40 is executed to ensure that the vehicle is locked.

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

[0068] When a vehicle's TBOX1 and / or ECU2 are illegally altered or an unregistered program is illegally written, the vehicle lock management module 3 issues a lock command to ECU2 via TBOX1, thereby commanding the entire vehicle to enter the locked state. However, if the TBOX1 and / or ECU2 to which the unregistered program is illegally altered or written does not have the lock function, an anomaly occurs in the command exchange process between TBOX1 and ECU2. Therefore, if the power distribution management module 4 detects an anomaly in the command exchange process between TBOX1 and ECU2, it can directly control the power supply to the vehicle's electrical equipment 5, causing the vehicle to be unable to operate normally and enter the locked state. This vehicle locking method solves the problem of the OEM being unable to lock the vehicle when the replaced ECU2 and / or TBOX1 itself does not have the lock and unlock functions.

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