Step 301: and the remote intelligent terminal to be bound on the vehicle is provided with a VIN code reading and writing zone bit and a VIN code instruction sending zone bit.
Step 302: the remote intelligent terminal judges whether VIN (vehicle identification number) condition is met or not; if yes, go to step 303; otherwise, step 310 is performed.
Specifically, the obtaining the VIN code condition includes:
1) and the VIN code reading-writing flag bit is not set.

Specifically, the remote intelligent terminal detects whether a VIN code sent by the vehicle control unit is received within a set time, and the steps include A) to D):
A) the remote intelligent terminal detects whether the VIN code of a first set digit sent by the vehicle controller is received within a first set time; if not, return to execute step 311.
B) If the remote intelligent terminal receives the VIN code of the first set digit transmitted by the vehicle controller within the first set time, detecting whether the VIN code of the second set digit transmitted by the vehicle controller is received within the second set time; if not, return to execute step 311.
C) If the remote intelligent terminal receives the VIN code of the second set digit transmitted by the vehicle control unit within the second set time, whether the VIN code of the third set digit transmitted by the vehicle control unit is received within the third set time is detected; if not, return to execute step 311.
D) If the remote intelligent terminal receives the VIN code of the third set digit sent by the vehicle control unit within the third set time, combining the obtained VIN code of the first set digit, the obtained VIN code of the second set digit and the obtained VIN code of the third set digit to obtain the VIN code.
The set time, the first set time, the second set time, and the third set time are determined by a hardware system of the entire vehicle, for example, the set time is 35s, the first set time is 10s, the second set time is 10s, and the third set time is 10 s.
It should be noted that, the embodiment of the present invention is a set of safe and reliable protocols for reading VIN codes, which are established on the basis of complying with the ISO14229 diagnostic protocol. Specifically, the VIN code with the first set number of bits is the first 3 bits of the VIN code, the VIN code with the second set number of bits is the 4 th bit to the 10 th bit of the VIN code, and the VIN code with the third set number of bits is the 11 th bit to the 17 th bit of the VIN code.
Step 306: checking whether the VIN code meets the coding requirement; if yes, go to step 307; otherwise, return to execute step 311.
Specifically, the checking whether the VIN code meets the encoding requirement includes:
and checking whether each bit of the VIN code is a number between 48 and 57 or 65 and 90.
It should be noted that the VIN code is represented by ASCII code, and whether the VIN code is formed by combining digits and capital letters can be determined through the checking method.
Step 307: and the remote intelligent terminal stores the VIN code.
Step 308: and the remote intelligent terminal sets the VIN code read-write zone bit.
Step 309: the remote intelligent terminal reports the ID and the VIN code of the remote intelligent terminal to the Internet of vehicles service platform together, so that the Internet of vehicles service platform stores and binds the ID and the VIN code.
Step 310: and (6) ending.
