The embodiment of the invention discloses a starting control method of a hybrid electric vehicle and a starting control device for the hybrid electric vehicle. The starting control method of the hybrid electric vehicle comprises the steps that the torque of a P3 motor is controlled to enable a battery to provide driving power for the P3 motor, and meanwhile the torque of a P1 motor is controlled to enable the P1 motor to reach the target rotating speed within the shortest time; and after the P1 motor reaches the target rotating speed, the rotating speed of the P1 motor is kept unchanged, the positive torque of the P1 motor is driven by the engine to reach the peak value and then is gradually reduced to be negative torque, then the P1 motor charges the battery, and the battery discharges the P3 motor. According to the invention, the time of the P1 motor from positive torsion to negative torsion is advanced, so that the P1 motor generates power earlier to charge the battery, and the continuous power of the battery and the generated power of the P1 motor are used for driving together, so that the torque smoothness of the P3 motor is improved, and the acceleration time per hundred kilometers is shortened within 9 seconds.

    本申请实施例公开了一种混合动力汽车的起步控制方法及用于混合动力汽车的起步控制装置。所述混合动力汽车的起步控制方法包括控制所述P3电机扭矩使得所述电池向所述P3电机提供驱动功率,同时控制所述P1电机的扭矩以使所述P1电机在最短时间内达到目标转速;当所述P1电机达到目标转速后,保持所述P1电机的转速不变,所述P1电机在所述发动机的驱动下使其正扭矩达到峰值后逐步下降变为负扭矩,此后所述P1电机给所述电池充电,所述电池向所述P3电机放电。本申请将P1电机由正扭转为负扭的时间提前,以便P1电机更早的发电来为电池充电,使用电池持续功率加上P1电机的发电功率一起驱动,从而改善P3电机扭矩平顺性,并缩短百公里加速时间在9秒内。
