The embodiment of the invention discloses a torque distribution method and device for a parallel hybrid power vehicle. The torque distribution method comprises the steps that the current working condition of the vehicle is determined based on the current state parameter of the vehicle; the current SOC state of a power battery in the vehicle is obtained; and torque distribution is carried out between an engine and a driving motor based on the current working condition and the current SOC state. According to the embodiment of the invention, the torque distribution is performed on the engine and the motor under different working conditions from the two aspects of the driving working condition and the battery energy management of the hybrid power vehicle, so that the requirements of a driver and the requirements of energy management are better met, and the dual requirements of the dynamic property and the economical efficiency of the whole vehicle are met.

    本公开实施例公开了一种用于并联式混合动力车辆的扭矩分配方法和分配装置,所述扭矩分配方法包括:基于车辆的当前状态参数确定所述车辆的当前工况;获取所述车辆中动力电池的当前SOC状态;基于所述当前工况以及所述当前SOC状态在发动机和驱动电机之间进行扭矩分配。本公开实施例从混合动力车辆的行驶工况和电池能量管理两个角度入手,对不同工况下发动机和电机进行扭矩分配,更符合驾驶员需求和能量管理需求,满足了整车动力性和经济性的双重要求。
