Abstract

The embodiment of the invention discloses a steering wheel angle control method, device and equipment and a storage medium. The method comprises the steps of receiving a vehicle speed signal and a steering wheel angle signal in the driving process; and when it is detected that the current vehicle speed signal is larger than a preset vehicle speed threshold value, updating the current steering wheel left-right limit angle and the current steering wheel maximum left-right controllable angle according to a preset time threshold value and a steering wheel angle signal in the driving process. According to the embodiment of the invention, the maximum controllable angle of the steering wheel is obtained by detecting the left-right steering angle of the steering wheel in real time and continuouslylearning the maximum left-right steering angle of the steering wheel; the left limit angle and the right limit angle of the steering wheel set in an APA controller can infinitely approach to the realleft dead angle and the real right dead angle of the steering wheel, so that the controllable angle range of the steering wheel with the APA function is reasonably increased, the degree of freedom ofAPA path planning and the like is improved, and more accurate and efficient parking is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a steering wheel angle control method, device, equipment and storage medium. Background technique [0002] The Auto Parking Assist (APA) function allows the driver to complete parking without operating the brake pedal, gear shift, steering wheel, or accelerator pedal. Among them, the APA controller implements path planning, vehicle tracking, etc., and the electric power steering mechanism (Electric Power Steering, EPS) as the actuator of the APA function receives the corner signal from the APA controller, thereby realizing the lateral control of the vehicle. The APA function relies on the EPS to achieve lateral control. The APA controller sends the corner request value to the EPS. After the EPS responds to the request, it controls the steering wheel to rotate without the driver intervening in the steering wheel. Combined with other controllers and ...
