A method and system for determining a fault in a vehicle braking system is provided. An electronic information processor obtains a brake pedal signal from a brake pedal indicating a driver's braking intent and obtains a vehicle brake response status signal from a brake system feedback sensor. The electronic information processor determines a fault condition when (1) the brake pedal signal indicates no brake pedal motion and the vehicle brake response signal indicates the occurrence of a vehicle brake response, or when (2) the brake pedal signal indicates brake pedal motion and the vehicle brake response status signal indicates no occurrence of a vehicle brake response. The electronic information processor controls output of an audio or visual indication of the fault condition and/or controls braking operation of the vehicle in response to the fault condition.
本发明提供了一种用于确定车辆制动系统中的故障的方法和系统。电子信息处理器从指示驾驶员制动意图的制动踏板获取制动踏板信号,并从制动系统反馈传感器获取车辆制动响应状态信号。当(1)制动踏板信号指示无制动踏板运动并且车辆制动响应信号指示发生车辆制动响应时,或者当(2)制动踏板信号指示制动踏板运动并且车辆制动响应状态信号指示未发生车辆制动响应时,电子信息处理器确定故障状态。电子信息处理器控制故障状态的音频或视觉指示的输出和/或响应于故障状态控制车辆的制动操作。
