The invention discloses a hybrid electric vehicle start-stop control method which comprises the steps that in the process of starting and/or shutting down an engine, the longitudinal output torque of a planet row is calculated, the compensation torque needing to be output by a driving motor is calculated according to the longitudinal output torque, and then the driving motor is controlled to output the compensation torque so that the compensation torque can be transmitted to a wheel end; therefore, the longitudinal output torque is counteracted. In this way, longitudinal shaking of the series-parallel connection type planet row hybrid power vehicle during starting and/or stopping can be effectively restrained, starting and/or stopping of the hybrid power vehicle are more coordinated and stable, and the quiet quality of the planet row hybrid power vehicle is improved.
本申请公开了一种混动车起停控制方法,可在起动和/或关停发动机的过程中,通过计算行星排的纵向传出扭矩,根据纵向传出扭矩来计算驱动电机应输出的补偿扭矩,再控制驱动电机输出补偿扭矩,以使补偿扭矩传递至轮端,从而抵消纵向传出扭矩。如此可有效抑制串并联式的行星排混动车在起动和/或停机时的纵向抖动,使混动车的起动和/或停机更协调平稳,提高了行星排混动车的静谧品质。
