AI Technical Summary

Problems solved by technology

Therefore, if the steering wheel angle is controlled based on the zero position of the steering wheel and the straight line, the vehicle will never be able to go straight, and it will be adjusted all the time, which will cause a series of safety problems, and the comfort will not be guaranteed.

Abstract

Embodiments of the present disclosure disclose a method and device for determining a steering wheel offset, a readable storage medium, and an electronic device, wherein the method includes: acquiring a current vehicle speed value in a current driving state of the vehicle; determine the current speed segment corresponding to the current vehicle speed value in the The target zero offset value corresponding to the steering wheel of the vehicle in the current speed segment; the embodiment of the present application only uses the sensor of the vehicle, does not require a vehicle dynamics model, and does not need to change the vehicle structural parameters. Wear, crosswind, uneven road surface and a series of reasons cause the steering wheel to be in zero position. The steering wheel offset value of the vehicle does not go straight; it provides the basis for precise control of automatic driving or assisted driving.

Description

technical field [0001] The present disclosure relates to vehicle control technology, in particular to a method and device for determining a steering wheel offset, a readable storage medium, and an electronic device. Background technique [0002] The adjustment of the lateral error (position and attitude) in the automatic driving or assisted driving of the car is mainly realized by controlling the steering wheel angle through the electric power steering system (EPS). Angle control is based on the assumption that the steering wheel is at zero and the vehicle is going straight. In the actual process, due to various reasons such as installation deviation, structural deviation, long-term wear, uneven road surface, side wind, etc., the steering wheel must maintain an angle in order to make the vehicle go straight, and this angle is dynamically changed. Therefore, if the steering wheel angle is controlled based on the zero position of the steering wheel going straight, the vehicle...
