Problems solved by technology

Among them, the calibration process of the camera is not only complicated but also easily affected by factors such as the installation angle. If the vehicle vibrates during driving, it will affect the calibration results, which in turn will affect the accuracy of the vehicle deviation recognition results.
In addition, the existing EPS (Electric Power St

Abstract

The invention provides a lane departure detection method and system for a vehicle, and the vehicle. The method comprises the following steps: acquiring position and posture information of the vehiclein a current lane; obtaining lateral distances between front wheels of the vehicle and lane lines according to the position and posture information of the vehicle; and if the lateral distances are less than the preset value, determining that the vehicle departs from the current lane. The lane departure detection method can accurately detect whether the vehicle departs from the lane or not in realtime, so that an alarm message can be sent to the user when the lane departure occurs, and the driving safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle lane departure detection method, system and vehicle. Background technique [0002] According to statistics, a large part of the traffic accidents on the expressway is due to the driver's negligence causing the vehicle to deviate from the driving route but not correcting the steering wheel angle in time to cause a collision. There are many reasons for the vehicle to deviate from the driving route, such as tire blowout, vehicle four-wheel alignment deviation, high-speed crosswind or uneven road surface, and these reasons are difficult to completely avoid. [0003] At present, for the formulation of lane departure recognition, the strategies of major foreign ADAS (Advanced Driver Assistant System, advanced driver assistance system) developers vary widely. The current lane departure recognition strategies all need to calibrate the camera first, then construct the geome...
