The invention relates to the technical field of automobile control, and particularly discloses a redundant brake control method and device based on a hub motor, a vehicle and a storage medium. The method comprises the steps that a wheel edge controller is arranged on each wheel, each wheel edge controller can independently control brake calipers of each wheel, under the normal condition, a hub motor is directly controlled through a brake pedal and an accelerator pedal, and the acceleration, deceleration and brake functions of the vehicle are achieved. The method comprises the following steps: continuously acquiring a yaw angle signal of a target vehicle and a hub motor rotating speed signal corresponding to each wheel, and judging whether the target vehicle has brake control failure or not; if brake control of the target vehicle fails, hydraulic redundant braking is achieved through the wheel edge controller, and when a part device related to drive-by-wire breaks down during information transmission or a hub motor breaks down in control, the wheel edge controller starts a data processing function according to control information; therefore, a wheel hub motor is temporarily replaced to realize a brake control function on the wheel.
本申请涉及汽车控制技术领域,具体公开了一种一种基于轮毂电机冗余制动控制方法、装置、车辆及存储介质。方法包括通过在每一车轮设置轮边控制器,每一轮边控制器可单独控制每一车轮制动卡钳,通常情况下,通过制动踏板及油门踏板对轮毂电机进行直接控制,实现对车辆的加减速及刹车功能,通过持续性获取目标车辆的横摆角信号、每一车轮对应轮毂电机转速信号,判断目标车辆是否出现制动控制失效;若目标车辆出现制动控制失效,通过轮边控制器实现液压冗余制动,当线控相关的零件装置在传输信息时出现故障,或者轮毂电机出现控制故障时,轮边控制器根据控制信息启动数据处理功能,以实现暂时替代轮毂电机对车轮实现制动控制功能。
