The invention belongs to the technical field of vehicle braking, and relates to an automobile multi-wheel independent braking loop which comprises a controller, a hydraulic oil source, a main normally-closed valve and a plurality of braking loops, the brake loop comprises a wheel rotating speed sensor, a first electro-hydraulic proportional control valve, a first normally-open valve, a one-way valve and a brake wheel cylinder, and the main normally-closed valve, the first electro-hydraulic proportional control valve, the first normally-open valve and the wheel rotating speed sensor are all communicated with the controller. The first electro-hydraulic proportional control valve is communicated with the main normally-closed valve, the electro-hydraulic proportional pressure control valves are controlled to carry out independent and continuous proportional control on the brake cylinder pressure of each wheel in real time and improve the driving comfort, and meanwhile, a redundant loop is adopted to improve the safety and reliability of a brake system.

    本发明属于车辆制动技术领域,涉及一种汽车多轮独立制动回路,包括控制器,依次连通的液压油源、总常闭阀和多个制动回路;所述制动回路包括车轮转速传感器以及依次连通的第一电液比例控制阀、第一常开阀、单向阀和制动轮缸,所述总常闭阀、第一电液比例控制阀、第一常开阀和车轮转速传感器均与所述控制器连通,所述第一电液比例控制阀与所述总常闭阀连通,其通过控制电液比例压力控制阀实时对各车轮的制动轮缸压力进行独立的、连续比例控制以及行车舒适性,同时,采用冗余回路提高了制动系统的安全性和可靠性。
