Document Type and Number:
WIPO Patent Application WO/2022/257370
Kind Code:
A1
Abstract:
A reverse control method for a steering wheel, and an automatic parking system and a vehicle. The reverse control method for a steering wheel comprises: calculating a remaining distance; calculating the minimum obstacle distance; calculating a positional offset and an angular offset during vehicle tracking; according to the remaining distance, the minimum obstacle distance, the positional offset and the angular offset, determining whether an activation condition for rotating a steering wheel in a reverse direction in advance is satisfied; if the activation condition is satisfied, calculating a rotation angle at which the steering wheel is rotated in the reverse direction; when the actual longitudinal position of a vehicle is controlled not to go beyond a buffer area, calculating a desired vehicle speed; and according to the rotation angle and the desired vehicle speed, controlling the transverse movement and the longitudinal movement of the vehicle.
