Abstract

The invention provides a lane keeping aiding method and system based on car networking and vehicle-mounted road recognition. The method includes the steps that a road image is collected; a lane mark is extracted according to the road image; whether or not the lane mark is complete and effective is judged, and if yes, a lane model is established according to the lane mark; if not, communication with a network-side car networking road information service system is established; vehicle position information is collected, and lane information of the position of the vehicle is acquired from the network-side car networking road information service system according to the vehicle position information; a lane model is established according to the lane information; the lane offset is calculated according to the lane model, and a lane keeping aiding control signal is generated according to the lane offset. The method can improve the reliability of the lane keeping aiding system.

Description

technical field [0001] The present invention relates to the technical field of automotive electronics, in particular to a lane keeping assistance method and system based on Internet of Vehicles and vehicle road recognition. Background technique [0002] With the development of the automobile industry, more and more attention has been paid to the safety of vehicle driving. Vehicles are generally equipped with a variety of systems for safe driving, one of which is the Lane Keeping Assist System (LKAS). When the vehicle deviates from the lane due to the driver's inattention and the driver does not correct the vehicle in time, the lane keeping assist system prevents the vehicle from deviating from its lane and controls the vehicle to stay in the original lane. [0003] Generally, the lane keeping assist system extracts lane information by analyzing images collected by cameras. However, if no lane markings are extracted from the image captured by the camera or the extracted lane...
