Embodiments of the present invention provide a lane departure warning method, device, electronic equipment, and storage medium, wherein the method includes: determining the current road image, and based on the relative position between the vehicle and the lane line indicated by the current road image, determining The estimated cross-road time of the vehicle; based on the estimated cross-road time of the vehicle and the deviation threshold of the corresponding driver of the vehicle, determine the deviation estimation result of the vehicle; wherein, the deviation threshold is based on the The driver's historical driving behavior data and / or historical violation data; if the estimated departure is about to depart, a lane departure warning is performed. The lane departure warning method, device, electronic device and storage medium provided by the embodiments of the present invention improve the flexibility and accuracy of the lane departure warning, and optimize the driver's experience while ensuring safe driving.
Description
technical field [0001] The invention relates to the technical field of vehicle intelligent control, in particular to a lane departure warning method, device, electronic equipment and storage medium. Background technique [0002] Unconscious lane departure is the main cause of vehicle traffic accidents, mainly due to factors such as driver fatigue and distraction. Therefore, a driving assistance system with a lane departure warning function is of great significance in the field of driving safety assurance. [0003] However, the existing lane departure warning and assisted driving systems all use a uniform departure threshold when judging whether the vehicle deviates from the lane, which is not flexible enough. Contents of the invention [0004] Embodiments of the present invention provide a lane departure warning method, device, electronic equipment, and storage medium, which are used to solve the defect of poor flexibility due to uniform departure thresholds in the prior ...
