摘　　要：通过研究混合动力汽车操纵稳定性控制对电机回馈制动系统的要求及对相关工作状态进行分析,针对混合动力汽车设计了一种新颖的电机回馈制动与液压制动复合混合动力汽车操纵稳定性模糊控制系统,并讨论了前馈补偿控制器、模糊控制器、电机回馈制动协同控制器的设计与协同控制策略。以变道工况、高速转向工况及紧急制动工况为例,进行了混合动力汽车操纵稳定性控制试验研究,结果表明该操纵稳定性控制系统使车辆在以上工况运行时能够迅速、准确、安全地按照驾驶员的意图行驶,制动性能良好,而且在道路条件和行驶条件改变时具有较强的适应性和鲁棒性。Through research on the demand of motor regenerative braking related to the hybrid electric vehicle handing and stability control system and the analysis of its working state, a novel electro-hydraulic hybrid handing and stability fuzzy logic control system using a motor regenerative braking system and a hydraulic braking system was proposed. And, the feedforward compensation controller, fuzzy controller, motor regenerative braking collaboration controller design and its control strategies were developed. Taking the J-turn, single lane change and emergency braking at the vehicle high speed as examples, hybrid electric vehicle handing and stability simulation testing were implemented. All the simulation results show that the proposed controller and strategies are effective and robust in keeping the vehicle tracing the desired response quickly, and the vehicle braking performance is achieved even under some parameters changes in the system, such as steering angle input and road friction.
