混合动力汽车在低附着系数路面上制动时，电机再生转矩被切断，以保证ABS的正常功能，当ABS控制终止时，电机再生制动被重新接纳，避免了液压防抱死制动到电机再生制动的永久循环，设计了一种基于模糊逻辑的新型机电混合式防抱死制动系统，该系统采用两层递阶结构，第一层负责再生系统与防抱死制动系统之间的协调调节或相互作用，第二层负责制动力矩的分配与调节，第三层负责制动力矩的分配与调节。建立了再生制动与防抱死制动协调控制的回路仿真模型，研究了再生制动与防抱死制动协调控制策略和方法，采用模糊逻辑控制在低附着系数路面上进行了模拟制动，并进行了真实的实车制动现场试验。仿真分析和试验结果表明，该车辆制动性能良好，再生制动与防抱死制动功能协调一致，可以回收大量的制动能量，并且所提出的控制策略和方法是有效的。
Braking on low adhesion-coefficient roads, hybrid electric vehicle's motor regenerative torque is switched off to safeguard the normal anti-lock braking system(ABS) function.When the ABS control is terminated, the motor regenerative braking is readmitted.Aiming at avoiding permanent cycles from hydraulic anti-lock braking to motor regenerative braking, a novel electro-mechanical hybrid anti-lock braking system using fuzzy logic is designed.Different from the traditional single control structure, this system has a two-layered hierarchical structure.The first layer is responsible for harmonious adjustment or interaction between regenerative system and anti-lock braking system.The second layer is responsible for braking torque distribution and adjustment.The closed-loop simulation model is built.Control strategy and method for coordination between regenerative and anti-lock braking are developed.Simulation braking on low adhesion-coefficient roads with fuzzy logic control and real vehicle braking field test are presented.The results from simulating analysis and experiment show braking performance of the vehicle is perfect, harmonious coordination between regenerative and anti-lock braking function, significant amount of braking energy can be recovered and the proposed control strategy and method are effective.
