Abstract

The invention discloses a vehicle-mounted OBD terminal remote upgrading method. A vehicle and a background management system are included; a vehicle-mounted OBD terminal is arranged on the vehicle; the vehicle-mounted OBD terminal is electrically connected to a vehicle internal circuit; a communication module is arranged in the vehicle-mounted OBD terminal; and the vehicle-mounted OBD terminal is in communication connection with the background management system through the communication module. To overcome the defects of offline system upgrading, system upgrading and network transmission are combined, a mobile phone system online upgrading thought is introduced, a system version of the vehicle-mounted OBD terminal is managed through a platform, version verification and software package downloading can be performed by network transmission, and finally, system ROM online automatic upgrading can be achieved through an ROM upgrading strategy of the vehicle-mounted OBD terminal.

Description

Technical field [0001] The invention relates to the field of automotive electronics, and in particular to a remote upgrade method for a vehicle-mounted OBD terminal. Background technique [0002] On the Internet of Vehicles platform, car owners can understand vehicle status information (fuel consumption, mileage, speed, etc.) and other car-related services (maintenance, gas station, 4S shop, parking lot, etc.). Traditional vehicle terminal upgrades generally involve offline upgrades at special upgrade locations or 4S shops, which brings a lot of inconvenience to car owners. Summary of the invention [0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a remote upgrade method for a vehicle-mounted OBD terminal. This method aims at the drawbacks of offline system upgrades, combines system upgrades with network transmission, and introduces mobile phone system online upgrades. The idea is to manage the system version of the vehicle ...
