The invention discloses a P1 + P3 hybrid power gear shifting torque control method and system and a readable storage medium. The method comprises the steps that the gear requirement is obtained according to the vehicle state, the engine torque and the P1 motor torque are distributed, and a P3 motor is controlled to conduct dynamic compensation on the wheel side requirement torque; the front end of the clutch is requested to reduce the torque, the P1 motor is controlled to assist in clearing the torque so that the torque of the front end of the clutch can be zero, and the P3 motor is controlled to dynamically compensate the torque required by the wheel edge; the P1 motor is controlled to conduct auxiliary speed regulation on the actual rotating speed of the engine, and the P3 motor is controlled to conduct dynamic compensation on the wheel side required torque; and the P1 motor is controlled to assist in back-twisting, the P3 motor is used for maintaining the wheel-side required torque, back-twisting intervention is conducted through the automatic gearbox control unit, and the clutch output torque reaches the target torque. According to the method, the request torque is commanded through interaction of the HCU and the TCU, the torque is executed through cooperation of the engine and the double motors, the gear shifting execution sequence is guaranteed, and gear shifting robustness is also guaranteed.
本发明公开一种P1+P3混动换挡扭矩控制方法、系统及可读存储介质,该方法包括根据车辆状态获取挡位需求,分配发动机扭矩及P1电机扭矩并控制P3电机对轮边需求扭矩进行动态补偿;请求离合器前端降扭,控制P1电机进行辅助清扭,以使离合器前端扭矩为零,并控制P3电机对轮边需求扭矩进行动态补偿;控制P1电机对发动机实际转速进行辅助调速,控制P3电机对轮边需求扭矩进行动态补偿;控制P1电机辅助回扭,利用P3电机维持轮边需求扭矩,通过自动变速箱控制单元进行回扭干预,使离合器输出扭矩达到目标扭矩。本发明通过HCU和TCU的交互指挥请求扭矩,发动机和双电机的配合执行扭矩,既保证了换挡执行顺序又保证了换挡的稳健性。
