摘　　要：提出了一种基于速度预估的电动汽车驱动系统动态测试方法。将真实的电驱动置于前向仿真结构中,整个测试系统中控制信号与能量的传递与实车相同。以在相同转矩作用下机械惯量系统和电惯量系统的加速效果一致为控制目标,提出了速度预估控制法。汽车动力模型与台架系统实时通信,保证了测试系统的动态性。通过试验研究了驱动系统时变输入下测试系统的动态模拟效果,结果表明采用速度预估控制可以快速准确地实现电动汽车的惯量模拟,为电动汽车设计开发阶段动力性能测试提供了一种有效手段。A dynamic test method of electric vehicle drive system based on the speed prediction was presented. Real electrical drive was placed in facing-forward simulation structure, and the control signal and energy transmission of the entire test system was the same as the actual vehicle. In order to guarantee the action of mechanical inertia system and electric in- ertia system acceleration affects the same under the same torque, speed prediction control method was put forward. Real- time communication between vehicle model and bench system ensures the dynamism of test system. Time varying inputs to the drive system were studied with the test system. The results show that using the speed prediction control can quickly and accurately achieve electric inertia simulation of electric vehicle, thus provides an effective means for the design and devel- opment stage of the electric vehicle power performance testing.
