For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0018] Example 1

[0019] like Figure 1 As shown, the present invention discloses a remote writing system for vehicle identification numbers of new energy heavy trucks, comprising: The MES system is used to record the information of the vehicle and its binding with each component when scanning the QR code of the vehicle identification number and the QR code related to each controller information; The TSP platform is used to scan the vehicle identification number, bind the vehicle corresponding to the vehicle identification number, store the vehicle-related data uploaded by the on-board real-time monitoring device, and provide vehicle information query and vehicle control related services; The on-board real-time monitoring device is connected to the TSP platform and is used to receive the configuration data and related instructions including the vehicle identification number transmitted by the TSP platform. It is also used to detect the vehicle identification number issued by the vehicle controller and compare it with the vehicle identification number issued by the TSP platform. If the two are the same, the on-board real-time monitoring device will stop sending the vehicle identification number to the bus and report the flashing status of the vehicle identification code to the TSP platform; The gateway controller is used to forward the vehicle identification number message sent by the on-board real-time monitoring device to the CAN bus where the vehicle controller is located, so that data can be transmitted between the internal controllers of the vehicle; The vehicle controller is used to receive and store the vehicle identification number message sent by the on-board real-time monitoring device, then read the vehicle identification number, and send the vehicle identification number to the bus in a loop to complete the flashing.

[0020] The on-board real-time monitoring device TBOX has a networking function. After the vehicle identification number is bound to the on-board real-time monitoring device TBOX, the vehicle identification number and other related data will be uploaded to the MES system. Then, the relevant vehicle data in the MES system will be uploaded to the TSP platform by scanning the barcode with a barcode scanner. When the on-board real-time monitoring device TBOX is connected to the vehicle and logs into the TSP platform, the TSP platform sends the vehicle identification number to the on-board real-time monitoring device TBOX. The on-board real-time monitoring device TBOX sends the vehicle identification number to the CAN bus for the vehicle controller to read according to the set logic. The on-board real-time monitoring device TBOX sends the flashing status back to the TSP platform to facilitate checking whether the flashing is successful or not. Specifically, it includes the following technical solutions: When the staff uses a barcode scanner to scan the vehicle identification number QR code and the QR codes related to each controller information, the MES system records the vehicle and its information bound to each component into the MES system to ensure product traceability and quality safety; After the staff uses a barcode scanner to scan the vehicle identification number, the TSP platform will push the relevant vehicle information of the MES system to the TPS platform, and the TSP platform will record the relevant information.

[0021] When the on-board real-time monitoring device TBOX establishes a connection with the TSP platform for the first time, the configuration data including the vehicle identification number is transmitted to the on-board real-time monitoring device TBOX. After the on-board real-time monitoring device TBOX logs in, the TSP platform receives the national standard data uploaded by it and other relevant data on vehicle operation, and can also send relevant instructions to the on-board real-time monitoring device TBOX to achieve the purpose of remotely controlling the vehicle; After the on-board real-time monitoring device is powered on in the car, when it requests to log into the TSP platform for the first time, it receives the configuration data and stores the data in the internal storage space. After storing the data, the on-board real-time monitoring device TBOX will restart, and after startup, it will request to log into the TSP platform and try to establish a data transmission channel with the TSP platform. The on-board real-time monitoring device TBOX will send the vehicle identification number data in the form of a message to the CAN bus for other controllers to read and store, and receive the vehicle identification number issued by the vehicle controller and compare it with the vehicle identification number issued by the TSP platform. If the comparison is successful, it will stop sending the message to the bus. If the comparison is unsuccessful, it will continue to send the message; The gateway controller is responsible for forwarding relevant messages according to the communication protocol, and acts as a bridge between different CAN buses to enable data transmission between the internal controllers of the vehicle. In this system, it is responsible for forwarding messages such as the vehicle identification number sent by the on-board real-time monitoring device TBOX to the CAN bus where the vehicle controller is located; The vehicle controller is responsible for the normal driving of the vehicle, braking energy feedback, energy management of the vehicle engine and power battery, fault diagnosis and processing, vehicle status monitoring, etc. In this system, the vehicle identification number forwarded by the gateway is received, recorded and sent out, and the vehicle identification number is stored in the internal storage space after the vehicle is powered off, and is cyclically sent to the CAN bus after the vehicle is powered on.

[0022] In the specific implementation of this embodiment, if the on-board real-time monitoring device and the vehicle controller are on the same CAN bus, the gateway controller does not need to forward the vehicle identification number sent by the on-board real-time monitoring device.

[0023] In the system of this embodiment, the vehicle controller also serves as a storage and outbound controller for the vehicle identification number, and other controllers can be selected to replace its function.

[0024] In this system, the on-board real-time monitoring device TBOX stops sending the vehicle identification number to the bus after receiving the vehicle identification number sent by the vehicle controller and successfully comparing it. You can also choose to have the on-board real-time monitoring device TBOX detect the vehicle identification number sent by the vehicle controller in real time, and send the vehicle identification number sent by TSP to the bus when the vehicle is powered on and cannot receive it or the comparison fails.

[0025] Example 2

[0026] Figure 1 and Figure 2 In the specification, VIN (tsp) indicates the vehicle identification number sent by the TSP platform to the on-board real-time monitoring device TBOX, and VIN (vcu) indicates the vehicle identification number sent by the vehicle controller. Specifically, a method for remotely flashing the vehicle identification number of a new energy heavy truck is disclosed, and the method includes: The vehicle VIN code data is pushed to the TSP platform. When the vehicle is powered on, the on-board real-time monitoring device establishes a connection with the TSP platform and receives the vehicle identification number VIN sent by the TSP platform. tsp The vehicle real-time monitoring device will send the vehicle identification number VIN tsp Send to CAN bus; In response to the vehicle real-time monitoring device and the vehicle controller being on the same line, the vehicle controller receives the vehicle identification number VIN sent by the vehicle real-time monitoring device. tsp After that, read and store the vehicle identification number as VIN vcu , and send it to the CAN bus in a loop; The gateway controller sends the vehicle identification number VIN issued by the vehicle controller vcu Forwarded to the on-board real-time monitoring device, the on-board real-time monitoring device receives the vehicle identification number VIN sent by the vehicle controller vcu Then the vehicle identification number VIN issued by the TSP platform tsp Make a comparison; Response to the vehicle identification number VIN vcu Vehicle Identification Number VIN tsp If the vehicle identification number VIN is the same, the vehicle real-time monitoring device stops sending tsp , the VIN code flashing is completed.

[0027] In a specific implementation process, the method further includes: If the vehicle real-time monitoring device and the vehicle controller are not on the same line, the gateway controller will tsp Forward to the vehicle controller; The vehicle controller receives the vehicle identification number VIN tsp , record the information, and issue the vehicle identification number VIN vcu Loops are sent to the bus.

[0028] If the vehicle identification number VIN vcu Vehicle Identification Number VIN tsp If they are not the same, when the vehicle is powered on, the on-board real-time monitoring device will tsp cyclically sent to the CAN bus.

[0029] In the specific implementation process, when the vehicle cuts off the key power, the vehicle controller will receive the vehicle identification number VIN tsp Stored in the internal storage space, the vehicle controller will store the vehicle identification number VIN after the vehicle is powered on vcu The vehicle identification code VIN is read by the on-board real-time monitoring device. vcuIf the vehicle controller fails to store the vehicle identification number, the VIN code of the TSP platform needs to be used to issue a command to rewrite the vehicle identification number.

[0030] The present invention optimizes the vehicle identification number flashing process, and realizes the flashing and updating of the vehicle identification number information of the vehicle controller when the vehicle identification number is not manually flashed. When the vehicle identification number stored in the vehicle controller is lost, the vehicle identification number data can also be remotely sent through the platform to realize the remote active flashing of the vehicle identification number and improve the flashing efficiency. When the vehicle identification number stored in the vehicle controller is lost, the vehicle identification number is sent through the TSP platform. If the on-board real-time monitoring device TBOX will send the vehicle identification number to the bus, the vehicle controller can re-record the vehicle identification number after reading it, avoiding the time waste caused by the staff going to the site to flash the vehicle identification number.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
