摘要

以某典型纯电动车为研究对象，对其瞬态抖动问题进行分析与控制。首先，结合驱动系统常啮合的特点，建立考虑电机转子-齿轮传动系统的整车模型，对抖动现象进行机理推导和传递路径分析。然后从动力传动系统入手，建立其简化模型并进行前馈-后馈主动控制仿真和部分试验。在此基础上，从被动控制的角度进行动力总成悬置系统的优化。最后，对主被动综合控制的效果进行了基于整车仿真平台的验证。结果表明，所建整车模型适用于电动车抖动问题的仿真与控制；所用主被动相结合的控制方法，可以改善车身抖动情况、减小悬置点动反力，提高电动车的驾乘舒适性。

Abstract

Take a typical pure electric vehicle as object, analyzes its transient surge problem and control methods. Firstly, according to the constant mesh characteristics of the drive system, whole vehicle model was established considering motor rotor- gear transmission system, mechanism of surge phenomenon and transfer path analysis was derived. Then, from the perspective of the power transmission system, feed forward- feedback active control simulation based on the simplified model and parts of experiment were conducted. On this basis, optimization of the power train mount system was carried out from the facet of passive control. Finally, the simulation effect of the active- passive integrated control was validated based on whole vehicle platform. Results show that the whole vehicle model is suitable for the simulation and control of the electric vehicle’s surge problem; the active and passive combined control method can improve body surge situation, reduce the dynamic reaction force of mounting point and improve the ride comfort of vehicle.
