摘要
提出了基于动态协调控制的混合动力汽车牵引力分层控制体系。上层采用基于动态滑模的整车期望总驱动转矩制定策略;中层采用基于低通滤波的发动机目标转矩计算法和基于模型匹配2自由度控制的动态协调控制策略,准确实现期望的总驱动转矩;底层采用基于动态补偿的混合动力汽车牵引力控制退出策略。仿真结果表明,所提出的混合动力汽车牵引力控制系统能在无制动能耗情况下,快速、准确和平滑地实现对滑转车轮的控制。
A hierarchical traction control system for hybrid electric vehicle（HEVTCS） is proposed based on dynamic coordinated control.In upper layer a strategy for determining the desired total driving torque of vehicle based on dynamic sliding mode is adopted;in middle layer the desired total driving torque is accurately achieved by using calculating method of engine objective torque based on low-pass filtering and dynamic coordinated control strategy based on model matching 2 DOF control;while in bottom layer an exit strategy for HEVTCS based on dynamic compensation is adopted.The results of simulation show that the HEVTCS system proposed can speedily,accurately and smoothly realize the control of wheel spinning.
