An ABS (anti-lock brake system) electromagnetic valve is connected with a relay valve to form a valve control unit, a rear brake air cylinder is connected with three pipelines, one pipeline is connected with a brake pedal, one pipeline is connected with a proportional electromagnetic valve, one pipeline is connected with the valve control unit, the brake pedal is connected with a two-way one-way valve, and the other pipeline is connected with a proportional electromagnetic valve. The two-way one-way valve is connected with the proportional electromagnetic valve, the valve control unit is connected with the two-way one-way valve, the ABS electromagnetic valve is connected with the dynamic air chamber, and the brake pedal, the proportional electromagnetic valve, the ABS electromagnetic valve and the relay valve are connected with the whole vehicle controller through lines. According to the method, the possible risk of no braking condition when the pure electric vehicle runs on the low-attachment road surface can be effectively solved, the running safety of the pure electric vehicle is improved, and the vehicle AUTO HOLD function and the braking mistaken stepping prevention function can be expanded based on the function.

    本发明公开了一种低附路面制动安全系统及方法,ABS电磁阀与继动阀相连并形成阀控单元,在后刹储气筒上连接三路管路,一路管路与制动踏板相连,一路管路与比例电磁阀相连,一路管路与所述阀控单元相连,制动踏板与双向单通阀相连,双向单通阀与比例电磁阀相连,阀控单元与双向单通阀相连,ABS电磁阀与动气室相连,制动踏板、比例电磁阀、ABS电磁阀和继动阀通过线路与整车控制器相连。本发明可以有效的解决纯电动车辆行驶在低附路面时可能出现的无制动情况风险,提高了纯电动车的行驶安全,并且基于该功能可以拓展出车辆AUTO HOLD功能,及制动防误踩功能。
