[0016] The content expressed by each figure of the present application specification and the marks in the figure are briefly described as follows:

[0017] Figure 1 It is the principle diagram of the supervision control system of the utility model. DETAILED DESCRIPTION

[0018] The specific embodiment of the present application is further explained in detail by comparing the drawings and describing the optimal embodiment.

[0019] Lease vehicle after replacing TBOX or VCU, generally VIN code is written in its interior, but due to work fault or other reasons lead to not writing VIN code or not correctly writing VIN code, then all lead to unable monitoring vehicle, for example, VIN code is written in error in TBOX, then cloud server background monitoring data cannot correspond with vehicle, vehicle data cannot correspond with vehicle, then also belong to the category of unable monitoring vehicle operation.

[0020] Specific scheme is as follows:

[0021] As shown in Figure 1 A kind of new energy vehicle supervision control system, system includes TBOX, whole vehicle controller VCU;Vehicle VIN code is configured in advance in the memory of TBOX, VCU internal control unit.

[0022] For TBOX, it includes control unit, vehicle state monitoring unit, memory;Vehicle VIN code is configured in advance in the memory;Control unit is connected to vehicle state monitoring unit, memory respectively.

[0023] The vehicle state detection unit is used for detecting the starting state of the vehicle, and the output end thereof is connected to the control unit; the vehicle state detection unit is used for detecting the KL15 ON signal of the vehicle to determine whether the vehicle is started. When the KL15 ON state is detected, it is determined that the vehicle is started at this time, otherwise it is determined that the vehicle is in an off state.

[0024] The control unit of the TBOX is connected to the VCU through the CAN network, and the output end of the VCU is connected to the speed limiting unit. The speed limiting unit is used to execute the speed limiting instruction of the VCU to limit the vehicle speed, and the speed limiting unit is the power system of the whole vehicle.

[0025] The control unit reads the vehicle VIN code in itself and the vehicle controller VCU according to the starting state of the vehicle and verifies it, and the control unit outputs a speed limiting instruction signal to the vehicle controller VCU according to the verification result; the output end of the vehicle controller VCU is connected to the speed limiting unit, which is used to limit the vehicle speed through the speed limiting unit.

[0026] The working principle is as follows: when the control unit of the TBOX detects that the vehicle is in a starting state, that is, after the KL15 ON power-on signal, the control unit reads the VIN code stored in the memory and reads the VIN code stored in the VCU through the reading instruction, and compares and verifies the two, if the two VIN codes are the same, the verification is passed, otherwise the verification fails. If the verification is passed, it means that the TBOX VCU is matched and can be effectively monitored, at this time the control unit of the TBOX does not output any speed limiting instruction to the VCU; when the two are inconsistent, the control unit of the TBOX sends a speed limiting instruction to the vehicle VCU, and the VCU receives the speed limiting instruction and limits the vehicle speed to below 20KM / h through the speed limiting unit, which can reduce the running of the vehicle that cannot be monitored. This way will make the vehicle run very low, so that the user can handle it in time.

[0027] In order to remind the driver to handle after the verification fails, the output end of the vehicle controller VCU is connected to the vehicle alarm, which is used to send the corresponding speed limiting reminder through the vehicle alarm. When the VCU sends the speed limiting instruction to the speed limiting unit, the corresponding VIN code verification failure reminder is sent through the vehicle alarm, and the reminder can be sent through the vehicle instrument or the vehicle display screen.

[0028] Since the vehicle belongs to the lease nature, the alarm information needs to be told to the driver and monitored by the background, so the communication unit of the TBOX itself can be used to send an alarm signal to the background monitoring server. The control unit is connected to the cloud server through the communication unit, and the control unit sends an alarm information to the cloud server through the communication unit after the VIN code verification fails, which is convenient for the background monitoring server to monitor it. At the same time, in order to better monitor and control the vehicle that fails to verify, the position of the vehicle can also be uploaded to the cloud server as an alarm information. In order to obtain the position information, the control unit is connected to the vehicle positioning unit through the CAN network, and the control unit reads the vehicle positioning information and uploads it to the cloud server as an alarm information. The vehicle positioning unit includes but is not limited to GPS, Beidou and other positioning.

[0029] In another preferred embodiment, speed limit operation can effectively avoid the operation of the vehicle without monitoring, but in order to repair or overcome this problem, the driver needs to drive the vehicle to the repair point, so the speed limit will cause the car to be unable to go to the repair point. In order to let the user go to the repair point, a speed limit removal scheme is set:

[0030] The control unit is connected with the identity recognition unit, and the identity recognition unit is used to collect the identity signal of the current vehicle driver and upload it to the cloud server through the TBOX. The cloud server is connected with the background monitoring device; the background monitoring personnel control the vehicle speed limit removal instruction to be input into the control unit through the cloud server through the background monitoring device, and the control unit controls the vehicle controller VCU to remove the speed limit according to the received removal instruction. Under this scheme, the background monitoring personnel judges whether to remove the speed limit by themselves, and the face and other identity information recognized by the identity recognition unit is uploaded to the cloud server. The background monitoring personnel can see it by accessing the background cloud server through the mobile phone, computer and other background monitoring devices, and then can input the speed limit removal instruction through the mobile phone, computer and other background monitoring devices. When the speed limit removal instruction is input, the speed limit removal instruction will be transmitted to the control unit of the TBOX and then to the VCU, and the VCU will control the speed limit unit to remove the speed limit. At this time, the removal of the speed limit is only effective in this power-on process, and the next time the power is turned on, the TBOX will be compared again. In this way, the removal of the speed limit can facilitate the driver to go to the repair point for inspection and repair during the vehicle startup period.

[0031] Further, the speed limit release can also be set in an automatic release mode. Some identity information can be pre-set in the database. The cloud server is connected with the database, and the identity information data is pre-set in the database. The cloud server verifies the identity information in the database and the uploaded identity information, and outputs a corresponding speed limit release instruction according to the verification result. When the uploaded identity is successfully matched with the identity in the database at this time, the identity is recorded and the speed limit is released, because the identity information of the user is known at this time, who is driving the vehicle, so the user and the vehicle can be matched, which also belongs to a kind of monitoring. Therefore, the speed limit can be automatically released by this method, and the driver user can drive the vehicle in this power-on period, and the vehicle can be driven to the maintenance point in this power-on period.

[0032] The identity recognition unit includes a vehicle-mounted recognition unit, and the control unit is connected to the vehicle-mounted recognition unit through the whole vehicle CAN network, and is used for acquiring the collected identity information. The vehicle-mounted recognition unit includes but is not limited to a camera in the vehicle for face recognition and / or fingerprint recognition.

[0033] The above scheme can limit the speed of the TBOX and VCU of the rental vehicle when the TBOX and VCU are abnormally installed or replaced, meet the monitoring requirements, and can also release the limit to meet the maintenance requirements. The existing TBOX and VCU are not bound to the vehicle VIN, and a speed limiting method is implemented to ensure that the TBOX and VCU are correctly bound to the vehicle VIN during the process of updating the vehicle TBOX or VCU, so as to meet the normal monitoring of the platform to the vehicle and meet the management of the rental company to the vehicle.

[0034] When the whole vehicle switches from KL15 OFF state to KL15 ON state each time, the TBOX can correctly send the UDS (Unified Diagnostic Service) read VIN code instruction to the VCU. The TBOX needs to monitor the state of KL15 (ignition switch) in real time. KL15 OFF indicates that the ignition switch is off and the vehicle power is disconnected; KL15 ON indicates that the ignition switch is on and the vehicle power is connected. When the TBOX detects that the KL15 state changes from OFF to ON, it should immediately send the UDS read VIN code instruction to the VCU. This instruction should follow the standard diagnostic communication protocol of the automotive industry, such as ISO 14229 or ISO 15765. After receiving the UDS read VIN code instruction sent by the TBOX, the VCU should access its stored VIN code information and return the VIN code to the TBOX. After receiving the VIN code returned by the VCU, the TBOX matches it with the VIN code saved in itself, and verifies it to ensure its correctness and validity. Once the VIN code verification is passed, the TBOX should store it in the local memory for subsequent use. And send the matching result to the VCU through the CAN signal, and the vehicle drives normally.

[0035] If the TBOX fails to receive a valid VIN code from the VCU after sending the UDS read VIN code instruction, or the received VIN code fails to match, the TBOX starts counting as "1"; at the same time, the TBOX sends the UDS read VIN code instruction to the VCU again, and when the TBOX fails to receive a valid VIN code from the VCU for 3 consecutive times, or the received VIN code fails to match the stored VIN code for 3 times, the TBOX should send an alarm information to the background platform, and multiple failures can reduce error interference and other problems. After receiving the alarm, the background platform can notify the service station staff or the relevant personnel of the leasing company to handle it; at the same time, the matching result is sent to the VCU through the CAN signal, and after the VCU receives the matching failure information, the turtle on the vehicle instrument is lit up, and at the same time, the vehicle control vehicle speed is 20km / h after 30S.

[0036] To ensure the reliability and stability of communication, a retry mechanism can be implemented. For example, if the TBOX does not receive a response after sending an instruction, it can retry sending the instruction within a certain time. For the case of communication exception or instruction execution failure, there should be a corresponding exception handling process, including recording error logs, triggering alarms, etc.

[0037] By implementing the above scheme, it can be ensured that every time the vehicle is switched from KL15 OFF to KL15 ON, the TBOX can send the UDS read VIN code instruction to the VCU, so as to ensure that the TBOX and the VCU correctly bind the vehicle VIN, and meet the normal monitoring of the platform to the vehicle and the management needs of the leasing company to the vehicle.

[0038] Obviously, the specific implementation of the present application is not limited by the above-mentioned manner, and various non-essential improvements using the method concept and technical scheme of the present application are within the protection scope of the present application.
