The invention discloses a vehicle braking diagnosis method, device and equipment, a storage medium and a program product, relates to the technical field of automobiles, and discloses the vehicle braking diagnosis method, device and equipment, the storage medium and the program product which comprise the steps that vehicle speed information and brake switch state information are obtained; vehicle working condition time is obtained based on the vehicle speed information and the brake switch state information; and obtaining a fault count value based on the vehicle working condition time, and judging a fault state based on the fault count value. According to the method, the vehicle working condition time is obtained, the fault count value is obtained based on the vehicle working condition time to judge the fault state, diagnosis of clamping stagnation failure of each path of signals is added on the basis of synchronous failure diagnosis of the two paths of signals, and the pedal clamping stagnation failure condition in the deceleration process and the pedal failure clamping stagnation condition in the acceleration process are considered; and the method is more safely suitable for complex system vehicle models with multiple controllers, so that the signal clamping stagnation failure in the vehicle braking process can be more accurately detected.

    本申请公开了一种车辆制动诊断方法、装置、设备、存储介质及程序产品,涉及汽车技术领域,公开了车辆制动诊断方法、装置、设备、存储介质及程序产品,包括:获取车速信息与制动开关状态信息;基于所述车速信息与制动开关状态信息获得车辆工况时间;基于所述车辆工况时间获得故障计数值,基于所述故障计数值判断故障状态。本申请通过获取车辆工况时间,基于所述车辆工况时间获得故障计数值判断故障状态,在两路信号同步失效诊断基础上增加对每路信号卡滞失效的诊断,考虑减速过程中的踏板卡滞失效情况以及加速过程中的踏板失效卡滞情况,诊断频率增加,更加安全地适用于多控制器的复杂系统车型,从而更精确的检测车辆制动过程信号卡滞失效。
