The invention discloses an inspection device and an inspection method for a check valve of a brake system. A check valve inspection apparatus of a brake system according to an embodiment of the present invention comprises: a check valve provided on a vacuum hose for unidirectionally supplying vacuum from an engine of a vehicle to a main booster side; a vacuum sensor outputting a signal corresponding to the vacuum of the main booster; a manifold pressure sensor which is provided on the vacuum hose on the engine side compared to the check valve and outputs a signal corresponding to the vacuum of the vacuum hose; an atmospheric pressure sensor that outputs a signal corresponding to atmospheric pressure according to the position of the vehicle; a brake pedal sensor that outputs a signal corresponding to an operation amount of a brake pedal; and a control unit that detects whether or not the check valve is abnormal on the basis of signals received from the vacuum sensor, the manifold pressure sensor, the atmospheric pressure sensor, and the brake pedal sensor, respectively.

    本发明公开一种制动系统的止回阀检查装置及检查方法。根据本实施例的制动系统的止回阀检查装置包括:止回阀,设置在用于从车辆的发动机向主助力器侧单向供应真空的真空软管上;真空传感器,输出与所述主助力器的真空相对应的信号;歧管压力传感器,相比所述止回阀设置在所述发动机侧的所述真空软管上,并输出与真空软管的真空相对应的信号;大气压传感器,输出与根据所述车辆的位置的大气压相对应的信号;制动踏板传感器,输出与制动踏板的操作量相对应的信号;以及控制部,基于从所述真空传感器、所述歧管压力传感器、所述大气压传感器和所述制动踏板传感器分别接收的信号,检测所述止回阀是否异常。
