提出了基于深度混合动力电动汽车的牵引力分层控制方法。上层控制中提出了基于动态滑模的驱动轮目标驱动力矩制定策略;下层控制中提出了电机转矩单独控制策略、基于转矩动态协调的发动机电机协调控制策略以及工况识别逻辑。最后开发了仿真和硬件在环试验平台,结果表明,本文方法能够快速、准确、平稳地实现对打滑车轮的控制,改善了深度混合动力汽车的起步性能、加速性能以及稳定性能。

Traction control method for full hybrid electric vehicle

Hierarchical traction control method for full hybrid electric vehicle was proposed.In the top layer,target driven torque generate strategy based on dynamical sliding mode control was proposed;In the bottom layer,several strategies were proposed such as motor torque individual control strategy,coordinate control strategy of engine and motor based on torque dynamic coordinate control,and pattern recognition logic.At last,simulation and hardware-in-loop test platforms were built.Test results show that the proposed method can control slipped wheels quickly,accurately and smoothly to improve starting performance,accelerating performance,and driving stability of hybrid electric vehicle.
