The invention provides a gear shifting control method for a vehicle power system. In the rotating speed synchronization step of the gear shifting control method, the expected rotating speed difference and the rotating speed reference value are calculated through the parameters of the vehicle, and whether the rotating speed synchronization step is executed smoothly or not is judged according to the size relation between the absolute value of the expected rotating speed difference and the absolute value of the rotating speed reference value. According to the gear shifting control method in the prior art, whether the rotating speed synchronization step is executed smoothly or not is judged through the time threshold value in the rotating speed synchronization step. In this way, according to the gear shifting control method, the problems of mistaken interruption and accidental acceleration of the vehicle possibly caused by the scheme in the prior art can be solved. Furthermore, the invention further provides a gear shifting control device adopting the gear shifting control method, and the gear shifting control device also has the same effect.

    本申请提供了一种用于车辆动力系统的换挡控制方法。在本申请的换挡控制方法的转速同步步骤中,利用车辆的参数计算期望转速差和转速基准值,根据期望转速差的绝对值与转速基准值的绝对值两者之间的大小关系判断转速同步步骤是否顺利执行,来代替现有技术的换挡控制方法在转速同步步骤中利用时间阈值判断转速同步步骤是否顺利执行的方案。这样,根据本申请的换挡控制方法能够避免现有技术的方案所可能引起的误中断和车辆意外加速的问题。进一步地,本申请还提供了一种采用上述换挡控制方法的换挡控制装置,其也具有同样的效果。
