Furthermore, a secret key is generated in the compiling process of the singlechip compiler, the version to be upgraded of the vehicle equipment is encrypted, the safety of the version to be upgraded of the vehicle equipment is protected, and meanwhile, the platform can select the correct upgrade version according to the secret key.
And step S120, the platform acquires the vehicle attribute of the vehicle equipment in the configuration information of the upgraded version, calls a basic version corresponding to the vehicle attribute in the database according to the vehicle attribute, and edits the basic version according to the upgraded version to obtain a request version of the vehicle equipment.
That is to say, the platform loads the upgraded version of the car device, and can obtain the vehicle attributes of the car device in the configuration information of the upgraded version, where the vehicle attributes include a vehicle identification code, a vehicle type, an item, hardware, and the like of the vehicle, and according to the obtained vehicle type information, the vehicle type, the item, the hardware information, and the like of the basic version on the platform are edited by the automated script, and the automated script language can select a python language, and the like.
And step S130, the platform issues a request version according to the vehicle attribute.
After the vehicle attribute information is obtained in the previous step S120, the upgraded version of the vehicle equipment can be sent to the vehicle equipment to be upgraded according to the vehicle identification code, wherein the vehicle identification code is a code consisting of a 17-bit letter and a number, and has unique vehicle identification, so that each vehicle can be upgraded differentially according to the requirements of the vehicle equipment.
And step S140, the vehicle equipment receives the request version and installs the request version to realize the vehicle firmware upgrade.
