摘　　要：针对混合动力汽车实现上层控制求得的驱动轮目标驱动力矩,部分工况下需要协调控制电机系统和液压制动系统,为此提出基于多目标动态协调的电液复合控制策略。基于多目标动态协调的电液复合控制策略数学算法,仿真分析采取此种算法与否的两种情况下的仿真结果。对比结果可知:混合动力汽车采取这种控制方法时,防止了车轮打滑,提高了车辆加速性能,保证车辆的行驶稳定性。搭建试验平台,对比分析两种情况下控制实验结果,实验结果表明,电机系统和液压制动系统,快速、准确、平滑地实现了对打滑车轮的控制,提高了混合动力汽车的起步性能和加速性能,从而验证了仿真结果的正确性和算法的有效性。To control of the goal-driven moment of the driving wheel of hybrid electric vehicle, under some working conditions need to coordinate control motor system and hydraulic brake system, so a coordinated control system of the motor and the hydraulic brake system based on multi objective dynamic coordination is built. The hybrid control strategy of multi object dynamic coordination is designed, and mathematical model is established to analyze the performance of the vehicle. The result comparison shows that the control strategy prevent the wheel skid, improve the vehicle acceleration performance, and guarantee the stability of the vehicle. Test platform is set up, and the experimental results are compared and analyzed in two cases. The experimental results show that： compound control system for motor system and the hydraulic braking system, rapidly, accurately and smoothly realizes kumises pulley wheel control, improves the performance of the hybrid electric vehicle starting and accelerating performance, and verifies the effectiveness of the algorithm and correctness of the simulation results.
