When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and aspects of the disclosure that are consistent with certain aspects as detailed in the claims that follow.

Before introducing the embodiments of the present invention, the terms and background of the present invention are explained first:

electronic shift controller EGSM has different gears including: forward gear (Drive, D), Neutral (Neutral, N), Reverse (R), etc., specifically:

1. the gear D is the most frequently used gear, and can be completed by controlling an accelerator when the gear needs to be lifted (speed is increased);

2. the N gear is used for temporarily stopping the vehicle, the gear is engaged, the motion of the vehicle is stopped, the power is not interrupted, for example, when a traffic light is waited, a hand brake is pulled up at the same time, and the gear is forbidden when going downhill;
