The invention relates to the technical field of automobile control, in particular to a brake redundancy self-checking method and system, a vehicle and a storage medium, and the method comprises the following steps: when a brake master controller is responded to enter a post-operation stage, the brake master controller sends a self-checking instruction to a brake redundancy controller; after the braking redundancy controller receives the self-checking instruction in response to the braking redundancy controller, the braking redundancy controller executes a self-checking process to verify whether the braking redundancy controller has the braking active voltage buildup capacity or not; in response to verification that the brake redundancy controller does not have the brake active voltage buildup capability, prompting that the brake redundancy capability fails when the vehicle is powered on next time; wherein the post-operation stage refers to that wake-up power supplies of the brake master controller and the brake redundant controller are in an OFF state, but the brake master controller and the brake redundant controller are not completely dormant. Whether the brake redundancy capacity is normal or not can be judged in advance.

    本发明涉及汽车控制技术领域,具体涉及一种制动冗余自检方法、系统、车辆及存储介质,包括以下步骤:响应于制动主控制器进入后运行阶段时,所述制动主控制器向制动冗余控制器发送自检指令;响应于所述制动冗余控制器接收到所述自检指令后,所述制动冗余控制器执行自检流程,以验证所述制动冗余控制器是否具备制动主动建压能力;响应于验证出所述制动冗余控制器不具备制动主动建压能力时,在车辆下次上电时提示制动冗余能力失效;其中,所述后运行阶段是指所述制动主控制器和所述制动冗余控制器的唤醒电源处于OFF状态但所述制动主控制器和所述制动冗余控制器未完全休眠。本发明能够提前判定制动冗余能力是否正常。
