AI Technical Summary

Technical Problem

During gear shifting in an electric vehicle, a large speed difference caused by rapid acceleration or deceleration can lead to gear engagement failure, affecting the success rate of gear shifting.

Method used

By acquiring the current speed difference between the two ends of the coupling sleeve component and the vehicle acceleration, the duration required for the motor speed to reach the target speed is determined. After the timing is completed within this duration, the shifting mechanism is controlled to engage gears, and the shifting time is adjusted to adapt to rapid acceleration or deceleration.

Benefits of technology

It improves the success rate of gear engagement in electric vehicles during gear shifting and reduces gear engagement failures caused by excessive speed differences.
