The invention discloses a hybrid power equal-duration gear shifting control method. The method comprises the following steps: a gear shifting instruction is received, and a clutch is controlled to bedisengaged; a front-end motor is controlled to linearly and additionally output a reverse torque; the clutch is controlled to be completely disengaged, and a synchronizer in a gear shifting system iscontrolled to be disengaged from a current gear to make the current gear be disengaged and enter a neutral gear; a front-end motor is controlled to provide reverse torque for size control; whether a releasing gear and a target engaging gear are on the same shifting fork shaft or not is judged; the clutch and the synchronizer are controlled to act according to the result to make a transmission system enter the target gear; and the clutch is controlled to be combined and enter a transmission torque recovery stage to finish gear shifting. It is ensured that all the gear shifting process durationsare approximately the same, a driver has good driving experience, and the driver cannot obtain the feeling of inconsistent gear shifting waiting durations.
本发明揭示了一种混合动力等时长换挡控制方法,包括如下步骤:接收换挡指令,控制离合器开始脱开;同时控制前端电机线性增加地输出一个反向扭矩;控制离合器完全脱开,同时控制换挡系统中的同步器从当前齿轮挡位脱开,使当前齿轮挡位解除进入空挡;同时控制前端电机提供大小控制的反向扭矩;判断解除挡位与目标挂入挡位是否在同一根拨叉轴上;根据结果分别控制离合器和同步器动作,使变速器系统进入目标齿轮挡位;控制离合器结合并且进入传递扭矩恢复阶段,完成换挡。本发明确保所有换挡过程时长大致相同,使驾驶员具有良好的驾驶体验,使其不会获得到换挡等待时长不一致的感受。
