For the understanding of the present embodiment, the following detailed description will be given of the embodiment of the present invention.
The first embodiment is as follows:

when the riding mode (D gear) is converted into the parking mode (P gear), the vehicle is temporarily stopped, or a P gear button is manually pressed;
when the parking mode (P gear) is converted into the power-assisted pushing mode (T gear), the condition of the power-assisted pushing mode is met;
when the power-assisted push mode (T gear) is converted into the parking mode (P gear), the condition of the power-assisted push mode is not met any more, or the vehicle is stopped;
when the riding mode (D gear) is converted into the power-assisted pushing mode (T gear), the condition of the power-assisted pushing mode is met;
when the assist push mode (T-range) is converted into the riding mode (D-range), the condition of the assist push mode is no longer satisfied, or the vehicle rides.
