Embodiment Construction
[0033] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.
[0034] In a preferred embodiment, intelligent vehicle lane keeping control decision strategy design is a key technology of intelligent driving. The decision-making strategy based on machine learning is that the system learns the lane-keeping strategy autonomously from the lessons of success and failure by interacting with the environment in real time. The enhanced signal is the evaluation of the system control decision-making behavior, and its value directly reflects the "good" and "bad" of each decision-making behavior. The setting of the enhanced signal determines the judgment of the control decision-making behavior, which directly affects the quality of the entire intelligent vehicle lane keeping system.

Abstract
The invention relates to a lane keeping control method, comprising the following steps: using a camera to detect lane lines; measuring the distance between a vehicle and a lane line; normalizing the detection distance; designing an optimized enhanced signal on the basis of a Sigmoid function; The corresponding control decision-making behavior will be made according to the value of the enhanced signal and the normalized processing value of the offset. On the one hand, the machine learning method is used to set the continuous enhanced signal, which improves the reliability, comfort and stability of the vehicle lane keeping function compared with supervised learning; The center line repeatedly swings, which is closer to human driving.
Description
technical field [0001] The invention relates to automobile active safety, in particular to a lane keeping control method. Background technique [0002] With the development of science and technology and the improvement of human living standards, automobiles have become an indispensable means of transportation for human travel. In recent years, people's focus on cars has gradually shifted from usability to safety, comfort and intelligence. Among them, the safety of automobile driving is the focus of most countries in the world. In 2011, the number of traffic accident deaths in the top six countries with the world's car ownership was: the United States, 32,310, China, 62,000, Japan, 4,612, Germany, 4,009, Italy, 3,800, and Russia, 27,900. In 2012, there were 204,196 traffic accidents in China, 59,997 people were killed, 224,327 people were injured, and the direct property loss was 1,174,896,000 yuan. [0003] According to statistics, among traffic accidents, traffic acciden...
