摘要
针对并联式混合动力汽车(Hybrid electric vehicle,HEV)能量回收过程会影响整车稳定性控制的问题,分析了带有半主动悬架系统(Semi-active suspension,SAS)和防抱死制动系统(Anti-lock braking system,ABS)车型的能量回收系统结构,提出了一种协调分配电-液制动力矩,协调SAS和ABS系统集成控制策略,最大限度地兼容并联HEV能量回收效率和整车稳定性。通过利用CarSim与Simulink平台联合搭建了并联式HEV能量回收系统仿真模型,对集成控制策略进行模拟分析,并与单独控制策略进行对比。结果表明:集成控制策略能够更好地维持行驶稳定性,并合理地分配能量回收比例,提高了车辆燃油经济性。
Aiming at the influence on the vehicle stability control during the parallel hybrid electric vehicle(HEV)energy recovery process,this paper analyzes the energy recovery system structure with the semi-active suspension system(SAS)and anti-lock braking system(ABS),and proposes an integrated control strategy to distribute the electromotor-hydraulic braking torque and coordinate the SAS and ABS system,in order to maximum compatible with parallel HEV energy recovery efficiency and vehicle stability.A model of the parallel HEV energy recovery system was built on the CarSim-Simulink software platform,and simulation analysis was carried out on the integrated control strategy,and compared with the independent control strategy,the results show that the integrated control strategy is better able to maintain stability,allocate energy recovery ratio more reasonable,and improve fuel economy of vehicles.
