The invention discloses an automobile composite braking control method based on braking intention recognition, and relates to the technical field of electric automobile braking. The invention aims to solve the problem that the traditional braking intention only considers the brake pedal and the vehicle state and cannot effectively consider the road condition. The current road adhesion coefficient is measured in real time through the road state sensor, and the road adhesion coefficient and a brake pedal signal are included in brake intention recognition; the braking force of the front axle and the braking force of the rear axle are adjusted on the premise of following rules; motor braking and hydraulic braking are preferentially used as supplementation; and the adjusted braking force is transmitted to a hydraulic controller and a motor controller. The braking intention recognition is improved, the safety and the braking efficiency of the automobile during braking can be ensured, and meanwhile energy is recycled to the maximum extent.

    本发明公开了一种基于制动意图识别的汽车复合制动控制方法,涉及电动汽车制动技术领域。该发明为解决传统制动意图仅考虑制动踏板和车辆状态,无法有效考虑路面情况的问题。本发明通过路面状态传感器实时测量当前路面附着系数,将路面附着系数和制动踏板信号纳入制动意图识别中;在遵循规则的前提下对前、后轴制动力进行调整;优先使用电机制动,液压制动作为补充;将调整好的制动力传输至液压控制器和电机控制器。本发明在制动意图识别方面进行改进,可确保汽车在制动时的安全性和制动效能,同时最大程度地回收能量。
