摘要:
分布式驱动汽车由于其左右轮转矩独立可控等优点,近年来受到广泛关注;而两挡变速器的使用可有效提高此类电动汽车的动力性与经济性。本文针对分布式驱动汽车提出了一种轮毂电机两挡变速器构型,并针对该构型设计了基于前馈加反馈的无动力中断换挡控制策略,以解决两挡变速器换挡过程动力中断的问题。接着,针对左右轮毂电机两挡变速器协同换挡问题,提出基于逻辑门限的左右协同换挡控制策略,以避免车辆在换挡过程中产生的较大横纵向加速度突变。最后基于搭建的Simulink-Simscape模型进行了无动力中断换挡与左右协同换挡控制策略的仿真验证。仿真结果表明,本文所提控制策略可有效避免轮毂电机两挡变速器换挡过程的动力中断,并可有效减少左右不协同换挡所带来的整车横纵向加速度突变。
