The invention relates to the technical field of vehicle-mounted equipment, in particular to a miniature electric vehicle part configuration information transmission system and method.The method comprises the steps that when a vehicle part needs to be replaced, whether the replaced vehicle part is an original standard part or not is judged, and if yes, a VCU does not update information of the vehicle part; if not, whether the replaced automobile part is an electric control unit or not is judged, if not, a control unit used for forwarding the configuration information of the automobile part is obtained, a flashing module of the control unit is upgraded through an upper computer or a remote OTA module, and after the configuration information of the automobile part is updated, the configuration information is transmitted to a VCU through a CAN bus, and the updated configuration information of the automobile part is updated. And identifying the configuration information of the automobile part through the VCU, and updating the changed flag bit information of the automobile part and the configuration information of the automobile part to complete the updating and recording process of the automobile part.
本发明涉及车载设备技术领域,具体而言,涉及一种微型电动汽车零部件配置信息的传输系统及方法,该方法的步骤包括:当汽车零部件需要更换时,判断更换的汽车零部件是否为原厂标配零部件,若是,则VCU不更新该汽车零部件的信息;若否,则判断更换的汽车零部件是否为电控单元,若否,则获取用于转发该汽车零部件配置信息的控制单元,通过上位机或远程OTA模块对控制单元的刷写模块进行升级,在更新该汽车零部件的配置信息后,通过CAN总线传输至VCU处,并通过VCU识别该汽车零部件的配置信息,并对该汽车零部件变更的标志位信息以及汽车零部件的配置信息进行更新,完成汽车零部件更新记录流程。
