System to disconnect a vehicle and to configure

The invention discloses an end-of-line configuration system and a configuration method for a finished vehicle. The system comprises a vehicle type configuration database, end-of-line equipment which is applicable to a controller area network (CAN) platform, and one or more electric control units in the finished vehicle, wherein the vehicle type configuration database is used for storing and querying finished vehicle codes and the finished vehicle configuration information, corresponding to each finished vehicle code, of the vehicle type; the end-of-line equipment is used for acquiring the finished vehicle configuration information from the vehicle type configuration database, coding the finished vehicle configuration information and writing the finished vehicle configuration information into the electric control units; the end-of-line equipment is connected with the vehicle type configuration database and the electric control units through CAN communication; and the electric control units are used for acquiring configuration information codes from the end-of-line equipment. The invention has the advantages that: the structure of the vehicle is not changed; and the configuration ofthe finished vehicle is adjusted by flashing the configuration codes, so the quantity of the electric control units is effectively reduced, and the electric control units can be applied to vehicles of different configurations.
