Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0026] Such as figure 1 As shown, the process flow of a vehicle active steering control method in this scheme is as follows:

[0027] Judging the validity of the lane line, the validity of the high-precision map and positioning information, and the validity of the historical path information of the target vehicle;

[0028] When the valid judgment result of the lane markings is that the lane markings on both sides are valid;

[0029] If the high-precision map and positioning information and the historical path information of the target vehicle are invalid, the centerline path of the double-sided lane line is used for active steering control;

[0030] If one or all of the high-precision map and positioning information and the hist...

Abstract

The invention relates to the technical field of automobile control, and particularly relates to a vehicle active steering control method. The method comprises the steps of judging the lane line validity, the high-precision map and positioning information validity and the target vehicle historical path information validity; when the lane line validity judgment result is that the lane lines on the two sides are effective, if the high-precision map and positioning information and the target vehicle historical path information are invalid, performing active steering control by utilizing a centralline path of the lane lines on the two sides; when the lane line validity judgment result is that the single-side lane line is valid, if the high-precision map and positioning information and the target vehicle historical path information are invalid, performing active steering control by using the path after the single lane line deviates by half of the historical lane width; and when the lane line validity judgment result is that no lane line exists, carrying out active steering control according to any one piece of the validity information or carrying out active steering control after the multiple pieces of validity information are fused. The invention relates to the technical field of automobile control, and particularly relates to a vehicle active steering control method.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a vehicle active steering control method. Background technique [0002] The existing vehicle active steering control function can only work normally when the lane lines on both sides are detected, and keep the vehicle driving in the center of the lane according to the lane lines. However, due to traffic jams, snow, and mud, the lane lines on the road cannot be continuously detected. Therefore, the traditional active steering control function frequently exits and cannot work normally, which brings a bad driving experience to users. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle active steering control method that can still achieve active steering control in the case of lane line occlusion, aiming at the defects of the prior art. [0004] The technical solution of the present invention is: judging the validity of the la...
