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, in particular to a method for remotely upgrading a vehicle-mounted OBD terminal. Background technique [0002] With the Internet of Vehicles platform, car owners can learn about vehicle status information (fuel consumption, mileage, speed, etc.) and other car-related services (maintenance, gas stations, 4S stores, parking lots, etc.). Traditional vehicle terminal upgrades usually go to special upgrade locations or 4S stores for offline upgrades, which brings a lot of inconvenience to car owners. Contents of the invention [0003] Aiming at the deficiencies in 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 disadvantages of offline system upgrades, combines system upgrades with network transmission, and introduces the online upgrade method of mobile phone systems. The idea is to manage the...
