Description

Technical Field

[0001] The present invention belongs to the field of automobile anti-theft, and specifically relates to a new energy automobile anti-theft control method and system. Background Art

[0002] National regulations for new energy vehicles require the installation of TBOX, which needs to upload vehicle location information, vehicle driving information, and vehicle fault alarm information to the platform, so that the state and vehicle manufacturers can monitor vehicle location and vehicle operation status. Most new energy logistics vehicles are mainly engaged in vehicle leasing business. Leasing companies only charge rent, and the assets of the whole vehicle are relatively high. Leasing companies need to track the location of leased vehicles to avoid forcible confiscation of vehicles or remote restriction of vehicle driving when vehicles are not returned or rent is not paid on time.

[0003] In order to avoid the leasing company's vehicle positioning and speed limit, some leasing customers will privately unplug the vehicle's GPS antenna, unplug the TBOX, or replace the new TBOX without rebinding the vehicle's VIN number, resulting in the platform being unable to monitor the vehicle and unable to remotely restrict the vehicle's operation. In serious cases, the leased vehicle cannot be retrieved, resulting in asset loss.

[0004] In order to avoid the situation where the customer replaces the TBOX without binding the VIN code or unplugs the GPS antenna or TBOX harness, resulting in the platform being unable to query the vehicle location and being unable to retrieve the vehicle, causing asset losses, this application proposes a new energy vehicle anti-theft control method and system to prevent the vehicle from losing its location function due to human factors. Summary of the invention

[0005] The present invention aims to overcome the deficiencies of the prior art and proposes a new energy vehicle anti-theft control method and system to achieve the following purposes: to realize remote monitoring of the vehicle and to ensure that the operation of the vehicle can be remotely restricted when the vehicle is abnormal, so as to facilitate the recovery of the rental vehicle.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: a new energy vehicle anti-theft control method, the method comprising the following steps:

[0007] Step S1, establishing communication connections between the new energy vehicle management platform and TBOX, and between TBOX and the vehicle controller in sequence;

[0008] Step S2, binding the same vehicle VIN number to the new energy vehicle management platform, TBOX, and vehicle controller respectively;

[0009] Step S3: Determine whether to actively turn on the vehicle anti-theft control according to the vehicle status, the communication status between TBOX and the vehicle controller, and the VIN number comparison result between TBOX and the vehicle controller; the vehicle status includes the vehicle GPS signal, vehicle driving information, and vehicle fault alarm information.

[0010] Preferably, in step S1, the new energy vehicle management platform is configured in a remote server and wirelessly connected to the TBOX, the TBOX and the vehicle controller are configured in the vehicle, and the TBOX is connected to the vehicle controller via a CAN bus.

[0011] Preferably, in step S2, the TBOX and the vehicle controller write the same vehicle VIN number when the vehicle is offline for electrical inspection. At the same time, after the vehicle is offline for electrical inspection, the TBOX sends its own VIN number to the new energy vehicle management platform for binding.

[0012] Preferably, in step S3, judging whether to actively turn on the vehicle anti-theft control according to the status of the whole vehicle includes: obtaining the status of the whole vehicle uploaded by TBOX according to the corresponding VIN number, and when it is found that the vehicle position exceeds the preset operating area, the vehicle is driving in violation of traffic rules, or the whole vehicle breaks down, the new energy vehicle management platform issues a command to turn on the vehicle anti-theft control according to the corresponding VIN number and forwards it to the whole vehicle controller through TBOX; the whole vehicle controller executes the vehicle anti-theft control command accordingly, and at the same time feeds back the execution result to the new energy vehicle management platform through TBOX.

[0013] Preferably, in step S3, judging whether to actively turn on the vehicle anti-theft control according to the status of the whole vehicle includes: TBOX acquires the vehicle GPS signal in real time and sends it to the new energy vehicle management platform; when TBOX loses the vehicle GPS signal, TBOX starts timing; when the timing exceeds a preset time threshold, TBOX actively sends a command to turn on the vehicle anti-theft control to the whole vehicle controller, and the whole vehicle controller executes the vehicle anti-theft control command accordingly.

[0014] Preferably, in step S3, judging whether to actively turn on the vehicle anti-theft control is based on the communication status between TBOX and the vehicle controller, including: the vehicle controller periodically sends an online verification message to TBOX, and waits for feedback from TBOX. If TBOX does not feedback within a preset time, it is considered that TBOX is offline. At this time, the vehicle controller actively executes the vehicle anti-theft control command.

[0015] Preferably, in step S3, based on the comparison result of the VIN number between TBOX and the vehicle controller, it is determined whether to actively turn on the vehicle anti-theft control, including: when TBOX is online, the vehicle controller actively sends a message to read the VIN number stored in TBOX, and after receiving the VIN number, the vehicle controller compares it with the VIN number stored in itself, and if they are inconsistent, the vehicle controller actively executes the vehicle anti-theft control command.

[0016] Preferably, the vehicle anti-theft control includes: limiting the speed of the vehicle through a vehicle controller. Preferably, the speed limit is 20 km / h.

[0017] At the same time, this application also proposes a new energy vehicle anti-theft control system based on the above method, the system includes a new energy vehicle management platform, TBOX, and a vehicle controller, wherein the new energy vehicle management platform is connected to the TBOX, and the TBOX is connected to the vehicle controller.

[0018] The technical effect of the present invention is that the new energy vehicle management platform, vehicle controller, and TBOX all realize the binding of the same VIN number. When the VIN numbers inside the vehicle controller and TBOX are inconsistent, the GPS signal monitored by TBOX is lost for a certain period of time, the vehicle controller cannot monitor TBOX, and TBOX is replaced without binding the VIN number, the vehicle controller will execute the vehicle anti-theft control command, that is, limit the speed of the vehicle, avoiding customers to privately replace TBOX without binding the VIN code or unplug the GPS antenna and TBOX harness, ensuring that the platform can query the vehicle location and retrieve the vehicle to avoid asset losses caused by vehicle loss. At the same time, due to the needs of vehicle rental business, the leasing company can also send a speed limit instruction or release the speed limit instruction to TBOX through the new energy vehicle management platform, and the vehicle will respond to the speed limit or release the speed limit after powering on and off again.

[0022] The following is a further detailed description of the specific implementation of the present invention by describing the embodiments with reference to the accompanying drawings, with the purpose of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate its implementation. In order to make the technical solution of the present invention clearer, the present invention is explained by the following embodiments.

[0023] This embodiment proposes a new energy vehicle anti-theft control method, such as Figure 1 As shown, the method comprises the following steps:

[0024] Step S1, establishing communication connections between the new energy vehicle management platform and TBOX, and between TBOX and the vehicle control unit (VCU) in sequence;

[0025] Step S2, binding the same vehicle VIN number to the new energy vehicle management platform, TBOX, and vehicle controller respectively;

[0026] Step S3: Determine whether to actively turn on the vehicle anti-theft control according to the vehicle status, the communication status between TBOX and the vehicle controller, and the VIN number comparison result between TBOX and the vehicle controller; the vehicle status includes the vehicle GPS signal, vehicle driving information, and vehicle fault alarm information.

[0027] Specifically, in step S1 of this embodiment, Figure 2 As shown, the new energy vehicle management platform 1 is configured in the remote server and is wirelessly connected to TBOX 2. In this embodiment, advanced 4G / 5G communication technology is used to realize the communication between the new energy vehicle management platform 1 and TBOX 2, ensuring the high speed, stability and security of data transmission, and ensuring that the data information such as the vehicle status detected by TBOX 2 can be fed back to the new energy vehicle management platform 1 in a timely manner, thereby realizing remote monitoring of the vehicle.

[0028] TBOX2 and the vehicle controller 3 are configured in the vehicle, and TBOX2 is connected to the vehicle controller 3 via the CAN bus. As a high-speed communication network in the vehicle, the CAN bus follows the strict CAN bus protocol, which can not only meet the real-time requirements of data transmission, but also ensure data accuracy, so that the vehicle controller 3 can timely feedback the execution results of the vehicle anti-theft control command. At the same time, the CAN bus also has the advantages of low power consumption and simple layout, which reduces the cost of this embodiment. The vehicle controller 3 is also connected to other vehicle control systems in the vehicle, for example, it is connected to the vehicle power system to obtain vehicle driving information in real time; it is connected to the cockpit domain control system to call the audio, screen and other equipment in the cockpit domain.

[0029] In step S2 of this embodiment, TBOX2 and the vehicle controller 3 write the same vehicle VIN number when the vehicle is offline for electrical inspection. Offline electrical inspection is the last link of the vehicle production line. In order to ensure that the vehicle VIN number written by TBOX2 and the vehicle controller 3 is consistent, this embodiment adopts a CRC (cyclic redundancy check) algorithm to perform multiple checks on the written VIN number to ensure data integrity. Once an error is found in the check, an alarm is immediately issued and the data is rewritten until the check passes.

[0030] At the same time, after the vehicle offline electrical inspection is completed, TBOX2 sends its own VIN number to the new energy vehicle management platform 1 for binding when the vehicle is powered on for the first time. In order to ensure that the VIN numbers bound to the new energy vehicle management platform 1, TBOX2, and the vehicle controller 3 are consistent, before TBOX2 uploads the VIN number, TBOX2 actively sends a diagnostic message to read the VIN number stored in the vehicle controller 3, and verifies it with its own VIN number. Only after the verification is passed will the VIN number be sent to the new energy vehicle management platform 1. At the same time, after receiving the VIN number, the new energy vehicle management platform 1 can also call the vehicle production line database for verification to ensure that each vehicle has a VIN code.

[0031] In the actual use of leased vehicles, there may be phenomena such as failure to return the vehicle when it is due, failure to pay the rent overdue, malicious theft, and dangerous use of the vehicle. Obviously, these phenomena will not only cause asset losses to the leasing company, but also bring safety hazards to the vehicle users. In order to solve the above problems, the leasing company needs to remotely monitor the leased vehicles and can also actively issue remote commands to restrict the vehicles. Therefore, in step S3 of this embodiment, the leasing company can determine whether to actively turn on the vehicle anti-theft control according to the status of the whole vehicle due to the needs of the vehicle leasing business, specifically including: the new energy vehicle management platform 1 obtains the vehicle status uploaded by the corresponding TBOX2 according to the corresponding VIN number. When it is found that the vehicle position exceeds the preset operating area, the vehicle is driving in violation of traffic rules, or the whole vehicle fails, the new energy vehicle management platform 1 issues a vehicle anti-theft control command according to the corresponding VIN number and forwards it to the whole vehicle controller 3 through TBOX2; the whole vehicle controller 3 executes the vehicle anti-theft control command accordingly, and then feeds back the execution result to the new energy vehicle management platform 1 through TBOX2. Only when the vehicle is in the operating area, the vehicle is driving safely, and the vehicle has no faults, can the new energy vehicle management platform 1 send a command to release the vehicle anti-theft control and forward it to the vehicle controller 3 through TBOX2; the vehicle controller 3 responds to the command to release the vehicle anti-theft control.

[0032] In this embodiment, the vehicle anti-theft control includes: limiting the speed of the vehicle through the vehicle controller 3, and the specific speed limit value can be 20km / h. Such a speed limit ensures that the rental company can recover the rental vehicle in time, and at the same time, reduces the possibility of accidents involving rental vehicles. In actual implementation, the specific speed limit value can be flexibly changed according to actual conditions. Further, the vehicle anti-theft control can also include controlling the in-vehicle equipment, such as the vehicle audio, the vehicle screen, etc., through the vehicle controller 3 to provide sound and light warnings. There can be many specific means of vehicle anti-theft control, and in actual implementation, they can be flexibly selected according to actual conditions.

[0033] In order to avoid the leasing company's positioning and speed limit on the vehicle, some leasing customers will privately unplug the vehicle's GPS antenna. In order to solve the above problem, in step S3 of this embodiment, the vehicle GPS signal is used as a vehicle status, and whether to actively turn on the vehicle anti-theft control can be directly determined based on the vehicle GPS signal. Specifically, it includes: Under normal vehicle use, TBOX2 can obtain the vehicle GPS signal through the GPS antenna in real time and send it to the new energy vehicle management platform 1 to achieve real-time positioning of the vehicle, but when TBOX2 loses the vehicle GPS signal, TBOX2 immediately starts timing. When the timing exceeds the preset time threshold (set to 2 hours in this embodiment, it can be flexibly selected according to actual conditions during specific implementation), it is considered that the vehicle is abnormal and the vehicle is at risk of being stolen. At this time, TBOX2 actively sends a command to turn on the vehicle anti-theft control to the vehicle controller 3, and the vehicle controller 3 executes the vehicle anti-theft control command accordingly. This method ensures that the GPS antenna will not be unplugged to prevent the vehicle from being stolen.

[0034] Compared with TBOX which is often directly exposed in the cockpit, the vehicle controller needs to be built into the vehicle cockpit equipment due to its integration. Therefore, in order to evade the leasing company to locate and limit the speed of the vehicle, the first choice for criminals is to destroy TBOX to evade the leasing company to locate and limit the speed of the vehicle. For example, the relevant wiring harness of TBOX is unplugged. At this time, TBOX cannot exchange information with the new energy vehicle management platform 1 and the vehicle controller, and naturally cannot track the vehicle. In order to overcome the above problems, in step S3 of this embodiment, it can be determined whether to actively turn on the vehicle anti-theft control according to the communication status between TBOX2 and the vehicle controller 3, specifically including: the vehicle controller 3 periodically sends an online verification message to TBOX2, and waits for TBOX2 to feedback. If TBOX2 does not feedback within a preset time (set to 3s in this embodiment, it can be flexibly selected according to actual conditions during specific implementation), it is considered that TBOX2 is offline. At this time, the vehicle controller 3 actively executes the vehicle anti-theft control command, thereby ensuring that the relevant wiring harness of TBOX will not be unplugged to prevent the vehicle from being stolen.

[0035] Furthermore, in order to prevent the TBOX from being replaced to bypass the online detection of the vehicle controller, in step S3 of this embodiment, the VIN number between TBOX2 and the vehicle controller 3 is also compared, and according to the comparison result, it is determined whether to actively turn on the vehicle anti-theft control, which specifically includes: when TBOX2 is online, the vehicle controller 3 actively sends a message to read the VIN number stored in TBOX2, and the vehicle controller 3 compares the VIN number with the VIN number stored in itself after receiving the VIN number. If they are inconsistent, it is considered that the TBOX has been replaced. At this time, the vehicle controller 3 actively executes the vehicle anti-theft control command to prevent the vehicle from being stolen. At the same time, this also requires users to bind the VIN code in time when replacing TBOX to improve their safety awareness.

[0036] At the same time, this embodiment also proposes a new energy vehicle anti-theft control system based on the above-mentioned new energy vehicle anti-theft control method, such as Figure 2 As shown, the system includes a new energy vehicle management platform 1, TBOX2, and a vehicle controller 3, wherein the new energy vehicle management platform 1 is connected to TBOX2, and TBOX2 is connected to the vehicle controller 3.

[0037] In summary, the new energy vehicle management platform, vehicle controller, and TBOX of this embodiment all implement the binding of the same VIN number, realize one vehicle and one code, and facilitate the traceability and monitoring management of the vehicle. At the same time, in this embodiment, when the VIN numbers inside the vehicle controller and TBOX are inconsistent, the GPS signal monitored by TBOX has been lost for a certain period of time, the vehicle controller cannot monitor TBOX, and TBOX is replaced without binding the VIN number, the vehicle controller will automatically execute the vehicle anti-theft control command, that is, limit the speed of the vehicle, avoiding customers from privately replacing TBOX without binding the VIN code or unplugging the GPS antenna and TBOX harness, ensuring that the platform can query the vehicle location and retrieve the vehicle to avoid asset losses caused by vehicle loss. At the same time, due to the needs of vehicle rental business, the leasing company can also actively send a speed limit instruction or release the speed limit instruction to TBOX through the new energy vehicle management platform, and the vehicle will respond to the speed limit or release the speed limit after powering on and off again, thereby avoiding the risk of car theft in advance.

[0038] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
