The embodiment of the invention relates to the field of hydraulic braking, and discloses a hydraulic braking decoupling method which comprises the following steps: providing a pedal feeling for a driver through a pedal feeling module of an EHB-HD braking loop; sensing pedal operation of a driver through a displacement sensor connected with a pedal, and analyzing the pedal operation into a target pressure signal; when a brake motor of the EHB-HD brake circuit is in a normal working state, the EHB-HD brake circuit provides pedal feeling for a driver through a pedal feeling module, obtains the target pressure signal and provides brake assistance according to the target pressure signal; when a brake motor of the EHB-HD brake circuit is in a failure state, the ESC brake circuit is connected with a brake assisting function, and the ESC brake circuit provides brake assisting power by controlling the states of valves in the EHB-HD brake circuit and the ESC brake circuit. The control method can be at least used for solving the technical problem of hydraulic decoupling type electronic hydraulic brake system control.

    本申请实施例涉及液压制动领域,公开了一种液压制动解耦方法,包括通过EHB‑HD制动回路的踏板感模块为驾驶员提供踏板感;通过与踏板连接的位移传感器感知驾驶员的踏板操作,解析为目标压力信号;在EHB‑HD制动回路的制动电机处于正常工作状态时,EHB‑HD制动回路通过踏板感模块为驾驶员提供踏板感并获取所述目标压力信号,根据目标压力信号提供制动助力;在EHB‑HD制动回路的制动电机处于失效状态时,通过ESC制动回路接管制动助力功能,通过控制所述EHB‑HD制动回路和所述ESC制动回路中的阀门状态,由所述ESC制动回路提供制动助力。可以至少用以解决液压解耦式电子液压制动系统控制的技术问题。
