Abstract
本发明属于车辆制动控制技术领域，具体为一种商用车机电一体化复合防抱死制动协调控制策略。该策略采用分层控制架构：在控制决策层，通过模糊权重路面识别算法实时辨识当前路面峰值附着系数与最优滑移率，并基于改进的滑模控制算法计算防抱死制动所需总制动力矩；在扭矩分配层，以气压制动力矩为基础、电机制动力矩为补偿，依据电机外特性与车辆状态动态分配制动扭矩；在执行层，通过气动预制动间隙补偿策略，消除制动间隙并基于系统响应特性进行前馈补偿，以提高气动制动响应速度并抑制运动冲击。本发明能够解决气动制动非线性时变特性导致的控制精度不足问题，有效协调机电复合制动系统，在保证制动安全性的同时，显著增强能量回收性能。

The invention belongs to the technical field of vehicle brake control, and particularly relates to a mechanical-electrical integrated composite anti-lock brake coordination control strategy of a commercial vehicle. The strategy adopts a layered control architecture, namely, a current road peak attachment coefficient and an optimal slip rate are identified in real time through a fuzzy weight road surface identification algorithm at a control decision layer, and the total braking moment required by anti-lock braking is calculated based on an improved sliding mode control algorithm. The invention can solve the problem of insufficient control precision caused by nonlinear time-varying characteristics of pneumatic braking, effectively coordinates the electromechanical composite braking system, ensures braking safety and obviously enhances energy recovery performance.
