The invention provides an electro-hydraulic composite brake anti-lock braking system and a control method thereof. The system comprises a hydraulic brake actuating mechanism, a motor brake actuating mechanism and an environment sensing and control decision mechanism, the control mode of the hydraulic brake actuating mechanism is a three-channel type rear axle low-selection ABS, and according to different road conditions, the motor brake actuating mechanism adopts different control modes, and is combined with the hydraulic brake actuating mechanism to perform alternate compensation to brake wheels. The motor brake actuating mechanism plays a role in rapid adjustment and accurate adjustment in the whole regulation and control process, and the hydraulic brake actuating mechanism plays a rolein providing large torque. The pavement adhesive force is utilized to the maximum extent, and the respective advantages of a motor and the hydraulic actuating mechanism are combined to meet the braking requirements under different working conditions.
本发明提供了一种电液复合制动防抱死系统及其控制方法,包括液压制动执行机构、电机制动执行机构以及环境感知与控制决策机构,液压制动执行机构的控制模式为3通道式后轴低选ABS,依据不同的路况,电机制动执行机构采用不同的控制模式,与液压制动执行机构进行组合并交替补偿,对车轮进行制动。电机制动执行机构在整个调控过程中起快速调节与精准调节的作用,液压制动执行机构起到提供大转矩的作用。本发明最大化利用路面附着力,将电机与液压两执行机构的各自优点结合起来,以满足不同工况下的制动需求。
