Problems solved by technology

[0002] With the advancement of technology and affluent life, the penetration rate of vehicles in households has increased significantly. However, with the frequent use of vehicles, traffic accidents have also increased. Among them, traffic accidents caused by poor mental state of the driver accounted for more Most of them, such as fatigue driving or drunk driving, etc., when the mental state is not good, the driver cannot turn the steering wheel in real time when turning, and even straight roads may cause the vehicle to deviate due to the loosening

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The present invention is a method for warning of vehicle deviation and estimating the state of the driver. It extracts body signals to determine whether the vehicle is deviation and the amount of deviation, and analyzes the vehicle movement path and vehicle speed, etc., from the established driver state model. The most suitable condition is compared among the default conditions, and scores are given according to the situation to estimate the driver's men...

Abstract

The invention provides a method for warning vehicle deviation and estimating driver state. The method includes: establishing a drive state model including a relation among driver mental state, a vehicle movement path and vehicle speed, capturing the speed of a vehicle, vehicle body signals of a direction light and the like and a lane center deviation; utilizing a processor to judge whether the speed of the vehicle exceeds a preset speed or not, whether the direction light is turned on or not, whether the vehicle is on a lane line or not and the like, and if so, recapturing the vehicle body signals and the lane center deviation; otherwise, comparing with a driver state model in a database by the processor according to the lane center deviation and at least one deviation speed, and estimating the mental state of a driver.

Description

technical field [0001] The invention relates to a technology for judging the state of the driver, in particular to a method for warning the vehicle to deviate and estimating the state of the driver. Background technique [0002] With the advancement of technology and affluent life, the penetration rate of vehicles in households has increased significantly. However, with the frequent use of vehicles, traffic accidents have also increased. Among them, traffic accidents caused by poor mental state of the driver accounted for more Most of them, such as fatigue driving or drunk driving, etc., when the mental state is not good, the driver cannot turn the steering wheel in real time when turning, and even straight roads may cause the vehicle to deviate due to the loose steering wheel. [0003] There is a lane departure warning system in the current technology, which can detect whether the vehicle is driving in the middle of the lane, and if the vehicle deviates from the middle of t...
