The gateway controller judges whether the current vehicle state meets the gateway controller flashing condition, the gateway controller flashing condition comprises information of vehicle power state, rotating speed, vehicle speed, gear and the like, if the flashing condition of the gateway controller is not met, the preset flashing condition is detected again after a preset time (such as 5s) interval, and data flashing updating is carried out on the gateway controller until the preset flashing condition is met, or the data flashing updating process on the gateway controller is abandoned until the preset detection times are reached.
Specifically, the step of performing data update processing on the gateway controller according to the flush data includes: and converting the flash data into data which can be identified by the controller, and updating the data of the gateway controller according to the data which can be identified by the controller. The gateway controller converts the locally stored flash data into a diagnosis flash data form according to the flash flow, and converts the data into data which CAN be recognized by the controller through an interaction layer and a CAN driving layer to complete data downloading and updating.
