According to the gear shifting control method, when a specified gear shifting switching signal is received, a dual-motor vehicle switches the mode that an engine provides wheel end torque through an input shaft into the mode that a second motor provides wheel end torque. The dual-motor vehicle control brake is combined with the sun gear. And the dual-motor vehicle adjusts the rotating speed of the engine to the target rotating speed of the engine corresponding to the target gear through the first motor. And the dual-motor vehicle controls the clutch to be in a combined state. The dual-motor vehicle switches the mode that the wheel end torque is provided by the second motor to the mode that the wheel end torque is provided by the engine through the input shaft. The second motor is adopted to maintain the torque needed by the wheel end of the vehicle during gear shifting switching, the engine is adopted to provide the torque needed by the wheel end of the vehicle after switching is completed, smooth transition of the torque of the wheel end is achieved, good smoothness is achieved, and the invention further provides a gear shifting control system and a double-motor vehicle.

    本发明提供一种换挡控制方法,在接收到指定换档切换信号时,双电机车辆将由发动机通过输入轴提供轮端转矩切换为由第二电机提供轮端转矩。双电机车辆控制制动器与太阳轮相结合。双电机车辆利用第一电机将发动机的转速调整至在目标档位对应的发动机目标转速。双电机车辆控制离合器处于结合状态。双电机车辆将由第二电机提供轮端转矩切换为由发动机通过输入轴提供轮端转矩。通过在换挡切换时采用第二电机维持车辆轮端所需的转矩,并在切换完成后采用发动机提供车辆轮端所需的转矩,实现了轮端转矩的平滑过渡,具有良好的平顺性,本发明还提供了一种换挡控制系统以及双电机车辆。
