The invention discloses a P1 + P3 hybrid power gear shifting method and system, a readable storage medium and a vehicle. The method comprises the steps that vehicle driving information is obtained, and gear information of a hybrid power vehicle control unit and gear information of an automatic gearbox control unit are determined; performing response based on a torque clearing request of the automatic gearbox control unit, and controlling a motor to perform torque dynamic compensation on the automatic gearbox control unit; acquiring a speed regulation request of an automatic gearbox control unit, and controlling a motor to assist in speed regulation; and the control motor carries out torque dynamic compensation in the back-twisting control stage on the automatic gearbox control unit until the back-twisting torque meets a preset value, and gear shifting is completed. Through interactive confirmation of the hybrid power vehicle control unit and the automatic gearbox control unit, the gear shifting execution sequence is guaranteed, and gear shifting robustness is also guaranteed; in the gear shifting process, the defect that an engine is slow in response is overcome through auxiliary torque adjusting and speed adjusting of the P1 motor; and through dynamic torque compensation of the P3 motor, the driving quality of gear shifting is improved.

    本发明公开了一种P1+P3混动换挡方法、系统、可读存储介质及车辆,该方法包括获取车辆行驶信息,确定混合动力整车控制器和自动变速箱控制单元挡位信息;基于自动变速箱控制单元的清扭请求进行响应,控制电机对自动变速箱控制单元进行扭矩动态补偿;获取自动变速箱控制单元调速请求,控制电机辅助调速;控制电机对自动变速箱控制单元进行回扭控制阶段的扭矩动态补偿,直至回扭扭矩满足预设值,换挡完成。本发明通过混合动力整车控制器和自动变速箱控制单元的交互确认,既保证了换挡执行顺序又保证了换挡的稳健性;在换挡过程中通过P1电机的辅助调扭及调速,弥补了发动机响应慢的缺陷;P3电机的动态扭矩补偿,提高了换挡的驾驶品质。
