Vehicle configuration method of vehicle diagnostic device

Abstract

The present invention relates to a vehicle configuration method of automobile diagnosis instruments and comprises the following steps: firstly, a configuration database is provided; after automobile final assembly is finished, a characteristic key is generated according to the configuration demands of an automobile controller; the characteristic key corresponds to configuration information of the automobile controller; the controller corresponding to the automobile is configured through the characteristic key; secondly, when the configuration information of the automobile controller needing to be configured is updated, the configuration information of the corresponding controller is updated in the configuration database; thirdly, when the automobile is maintained, the characteristic key is read, and the configuration database is inquired through the characteristic key; if the configuration information of the controller is updated, the updated configuration information of the controller is written into the corresponding controller of the automobile. Compared with the prior art, the present invention can perform unified efficient management to the configuration information of controllers of vehicles in all types, which improves the flexibility, integrity, tightness and diagnosis efficiency of controller configuration.
