Embodiment Construction

[0034] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment in various embodiments of the present invention. The technical idea of ​​the present invention is not limited or limited thereto, and can be variously deformed and implemented by those skilled in the art .

[0035] The technical problem to be solved in this embodiment is to realize lane keeping of vehicles on the basis of lane line detection.

[0036] Specifically, such as figure 1 As shown, the solution of the embodiment of the present invention mainly includes: lane line detection; converting the lane line in the two-dimensional image to the vehicle body coordinates to obtain the real lane line; combining the information of the real lane line to obtain the position information of the virtual lane line ; Combining real lane line position information and virtual lane line position information to calculate the angle and degree of deviation of t...

Abstract

The invention provides a lane-keeping control method for a vehicle. The lane-keeping control method for the vehicle comprises the steps of first, using an image captured by a vehicle-mounted camera todetect a lane line and then converting the detected lane line from an image coordinate system into a vehicle body coordinate system. According to the lane-keeping control method for the vehicle, twoconcepts of a virtual lane line and a real lane line are presented; and the deviation angle and deviation degree of the vehicle relative to the lane are calculated according to position information ofthe real lane line and position information of the virtual lane line. Finally, steering control amount is calculated according to the deviation amount to realize lane keeping.

Description

technical field [0001] The invention relates to the field of vehicle automatic control, in particular to a vehicle lane keeping control method. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of human living standards, automobiles are increasingly playing an indispensable role in human life. In recent years, the safety of automobile driving has become the focus of most countries in the world today. According to statistics, among all motor vehicle accidents, traffic accidents caused by vehicle deviation from the lane account for up to 20 percent of all traffic accidents. It can be seen that the accidents caused by vehicle deviation from the lane have seriously affected people's life and property safety. [0003] In recent years, unmanned driving technology and advanced assisted driving have developed rapidly, and lane keeping is one of the indispensable technologies. Nowadays, many research institutions...
