The invention discloses a parallel type two-gear hybrid power gearbox gear shifting control method which comprises the following steps that a vehicle runs to a gear shifting point, a hybrid controller controls an engine and an ISG motor to reduce the torque, and the controller controls a TM motor to increase the torque; the hybrid controller controls the clutch to be disengaged through the gearbox controller, the gearbox controller controls the shifting fork to be disengaged from the first-gear gear set, and the gear enters a neutral gear; the ISG motor adjusts the rotating speed and controls the rotating speed of the shifting fork through the input shaft, and the gearbox controller controls the shifting fork to be coupled with the second-gear gear set. And the hybrid controller controls the clutch to be combined through the gearbox controller, and the engine and the ISG motor enter a torque control mode. The vehicle wheel end torque control system has the advantages that the TM motor, the ISG motor and the engine are matched with one another to meet the vehicle wheel end torque requirement, the power of the driving motors can be reduced, the driving motors with smaller specifications can be selected, and therefore the cost is reduced, and the layout is more reasonable.

    本发明揭示了一种并联式两挡混动动力变速箱换挡控制方法,包括如下步骤:车辆运行到换挡点,混动控制器控制发动机和ISG电机进行降扭,控制器控制TM电机进行升扭;混动控制器通过变速箱控制器控制离合器脱开,变速箱控制器控制拨叉脱离一挡齿轮组,挡位进入空挡;ISG电机调整转速,并通过输入轴控制拨叉的转速,变速箱控制器控制拨叉与二挡齿轮组耦合;混动控制器通过变速箱控制器控制离合器结合,发动机和ISG电机进入扭矩控模式。本发明的有益效果主要体现在:TM电机、ISG电机以及发动机三者相互配合满足车辆轮端扭矩需求,可降低驱动电机的功率,选择更小规格的驱动电机,从而降低成本,也使得布局更加合理。
