Abstract

The invention provides a vehicle and a lane centering control method and system applied to the vehicle. The method includes the steps that the deviation value of a center axis of the traveling vehicleand the median of a lane is obtained; the difference value between the deviation value and a preset deviation value serves as a lane control error value; the course angle value is calculated throughthe lane control error value and a first preset algorithm; the difference value between the course angle value and a current course angle value of the vehicle serves as a course control error value; and the steering wheel angle value is calculated through the course control error value and a second preset algorithm, so that a steering wheel of the vehicle rotates according to the steering wheel angle value, and automatic centering control over the vehicle is achieved. Few parameters need to be adjusted, the requirement for hardware of data processing is low, vehicle body transverse swinging can be effectively avoided, and user experience is improved.

Description

technical field [0001] The invention relates to the field of vehicle automatic control, in particular to a lane centering control method and system, and a vehicle applying the method or system. Background technique [0002] At present, automatic lane centering has become one of the important functions in the field of assisted driving / unmanned driving. Especially on expressways, automatic lane centering can effectively prevent traffic accidents caused by driver negligence and misoperation. The existing lane centering control methods / systems have problems such as large amount of calculation and difficult maintenance of the system, and some methods also have problems such as lateral shimmy of the vehicle body. It can be seen that the existing automatic centering control in the lane still needs to be continuously optimized. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a novel ...
