According to the technical scheme, the vehicle multi-controller flashing device comprises a first controller and a second controller; the first controller is used for communicating with the cloud server and a plurality of vehicle controllers in the same vehicle, downloading a to-be-updated program of the vehicle controller from the cloud server, and acquiring a vehicle VIN code and information of each controller of the vehicle by the first controller through the vehicle controller to complete priority numbering and address allocation and diagnosis of each vehicle controller; the second controller is used for communicating with the first controller and a plurality of vehicle controllers in the same vehicle; and the second controller receives and stores the to-be-updated program downloaded by the first controller, and writes each vehicle controller according to the priority number and address of each vehicle controller and the diagnosis result. The controller flashing time is greatly shortened, and the whole vehicle development cost is reduced.

    本发明采用的技术方案是:一种车辆多控制器刷写设备,包括第一控制器和第二控制器;其中第一控制器用于与云端服务器与同一车辆内的若干个车辆控制器通信,第一控制器从云端服务器下载车辆控制器的待更新的程序,第一控制器通过车辆控制器获取车辆VIN码以及车辆各控制器信息,并完成对各车辆控制器优先级编号及地址分配和诊断;第二控制器用于与第一控制器与同一车辆内的若干个车辆控制器通信;第二控制器接收第一控制器下载的待更新的程序并进行存储,并根据各车辆控制器优先级编号和地址以及诊断结果对各车辆控制器进行刷写。本发明大大缩短控制器刷写时间,减少整车开发成本。
