[0008] Step S2: After the vehicle is connected to the Internet of Vehicles platform, the Internet of Vehicles platform collects the mileage value and VIN information of the vehicle remote terminal, the mileage value and VIN information of the combination instrument, and the mileage value and VIN information of the engine ECU;

[0009] When the VIN information of the vehicle remote terminal collected for the first time is consistent with the VIN information of the instrument cluster and the engine VIN information, the vehicle networking platform stores and records the current VIN information and uses it as the initial VIN information, otherwise the instrument cluster displays an error;

[0010] When the mileage value of the vehicle remote terminal collected for the first time is consistent with the mileage value of the combination meter and the mileage value of the engine ECU, the vehicle networking platform stores and records the current mileage value as the initial value of the mileage value, otherwise the combination meter displays an error;

[0080] Embodiment 2:

[0081] Step S1: After the vehicle is offline, the vehicle parameters and VIN code are written into the vehicle remote terminal, instrument cluster and engine ECU through a dedicated diagnostic instrument.

[0082] Step S2: After the vehicle is connected to the Internet of Vehicles platform, the Internet of Vehicles platform collects the mileage value and VIN information of the vehicle remote terminal, the instrument cluster and the engine ECU. When the data is consistent for the first time, the Internet of Vehicles platform stores and records the current value as the initial value, otherwise the instrument cluster displays an error until the data is consistent.

[0083] like Figure 3 As shown, when the VIN information of the vehicle remote terminal collected for the first time is consistent with the VIN information of the instrument cluster and the engine VIN information, the vehicle networking platform stores and records the current VIN information and uses it as the initial VIN information, otherwise the instrument cluster reports an error display;

The vehicle networking platform stores and records the current mileage value as the initial value of the mileage value, otherwise the instrument cluster displays an error.

[0085] Step S3: The Internet of Vehicles platform periodically collects the mileage and VIN information of the vehicle remote terminal, the instrument cluster and the engine ECU. When the data are consistent, the Internet of Vehicles platform updates and stores the current mileage in real time; when the data are inconsistent, the Internet of Vehicles platform compares the mileage values ​​of the instrument cluster and the engine ECU with the difference between the mileage values ​​of the vehicle remote terminal GPS positioning, and the data with the smallest difference and no more than 10km is assumed to be accurate data by default, and is updated and stored in the Internet of Vehicles platform in real time;

[0086] like Figure 4 As shown, when the mileage value collected by the vehicle remote terminal is consistent with the mileage value of the combination instrument and the mileage value of the engine ECU, the vehicle networking platform stores and records the current mileage value;

[0090] When the smallest difference among the differences is greater than 10 km, the instrument cluster displays an error message.

[0091] The vehicle networking platform periodically collects the mileage value and VIN information of the vehicle remote terminal, the mileage value and VIN information of the combination instrument, and the mileage value and VIN information of the engine ECU;

[0092] When the collected VIN information of the vehicle remote terminal, the VIN information of the instrument cluster and the engine VIN information are consistent with the initial VIN information recorded by the Internet of Vehicles platform, the mileage value of the vehicle remote terminal, the mileage value of the instrument cluster and the mileage value of the engine ECU will continue to be collected; otherwise, the instrument cluster will display an error.

[0093] Step S4: The Internet of Vehicles platform periodically collects the mileage value and VIN information of the vehicle remote terminal, the instrument cluster and the engine ECU, compares the VIN code information and mileage data in turn, and makes a comprehensive decision to determine whether the vehicle instrument cluster needs to perform mileage and VIN code rewriting. The process is as follows: Figure 5 shown.

[0094] like Figure 5 As shown, in step S411, the vehicle networking platform periodically collects the VIN information of the instrument cluster and compares it with the VIN information stored in the vehicle networking platform. If the comparison result is consistent, no flashing is required; if the comparison result is inconsistent, the vehicle networking platform issues a diagnostic instruction to write the VIN information stored in the vehicle networking platform into the instrument cluster;

[0095] Step S412, the Internet of Vehicles platform periodically collects the mileage value of the combination meter and compares it with the mileage value stored in the Internet of Vehicles platform; if the difference is less than or equal to 10 km, no flashing is required; if the difference is greater than 10 km, the Internet of Vehicles platform issues a diagnostic instruction to write the mileage value stored in the Internet of Vehicles platform into the combination meter;

[0096] Step S421, the Internet of Vehicles platform periodically collects the VIN information of the engine ECU and compares it with the VIN information stored in the Internet of Vehicles platform. If the comparison results are consistent, no flashing is required; if the comparison results are inconsistent, the Internet of Vehicles platform issues a diagnostic instruction to write the VIN information stored in the Internet of Vehicles platform into the engine ECU;

[0097] Step S412, the Internet of Vehicles platform periodically collects the mileage value of the engine ECU and compares it with the mileage value stored in the Internet of Vehicles platform; if the difference in comparison is less than or equal to 10Km, no flashing is required; if the difference in comparison is greater than 10Km, the Internet of Vehicles platform issues a diagnostic instruction to write the mileage value stored in the Internet of Vehicles platform into the engine ECU.
