AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve a high degree of integration and free switching of multi-functional power modes with single-motor auxiliary drive and simplified mechanical structure. This results in power shock, synchronizer wear and mis-gear risk during power mode switching, affecting shifting reliability and vehicle driving comfort.

Method used

By limiting the first angle difference between adjacent power modes and the second angle difference between power modes, the switching between power modes is accurately determined, and the shift drum is controlled to rotate step by step to the target power mode. Combined with the state control of the synchronizer, smooth switching is achieved step by step, avoiding direct gear skipping.

Benefits of technology

It improves the smoothness and reliability of power mode switching, extends the life of mechanical components, reduces the matching error between the control algorithm and the actuator, and enhances the vehicle's operational stability and comfort.

Abstract

本发明提供的一种车辆动力模式切换方法、设备、车辆及存储介质,涉及车辆领域,以实现换挡毂非相邻动力模式间的逐级平顺切换,避免直接跳切导致的同步器打齿与动力冲击。该方法包括:确定目标动力模式对应的换挡毂的目标旋转角度;基于换挡毂的当前旋转角度和目标旋转角度,确定目标动力模式与当前动力模式之间的角度差值;在角度差值的绝对值大于第二角度差的情况下,该第二角度差大于相邻模式的预设角度差,控制换挡毂从当前旋转角度逐步切换至目标动力模式序列中每个动力模式对应的旋转角度,直至旋转至目标旋转角度;目标动力模式序列为从当前动力模式切换至目标动力模式的路径上所涉及的所有动力模式,按旋转方向依次排列形成的序列。
