Early warning method and early warning device based on driving distraction state

Abstract

The invention discloses an early warning method and early warning device based on a driving distraction state. The early warning method comprises the following steps: step one, acquiring traffic conditions and road conditions around a vehicle and identifying a driving behavior of a driver; step two, judging whether a distracted driving behavior exists or not according to the driver behavior, and if not, entering step three; if so, entering step 4; step three, judging whether the vehicle deviates from the lane or not based on the traffic conditions around the vehicle and the road conditions, ifnot, not sending out early warning and ending the early warning; if so, prompting the driver by voices, and ending the early warning after the prompt is finished; and step four, predicting an impending collision type and a lane deviation situation, and carrying out early warning of a corresponding level based on the predicted situation. According to the early warning device and the early warningmethod based on the driving distraction state, the risk level of the current driving behavior is judged based on the driving state of the driver, the driving environment and the vehicle attitude information and early warning can be performed according to the response state of the driver, so that traffic accidents are avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, in particular to an early warning method and early warning device based on driving distraction state. Background technique [0002] Distracted driving is a common unsafe driving behavior that can easily lead to traffic accidents. According to statistics, fatal accidents caused by distracted driving account for about 10% of the total number of fatal accidents. During driving, drivers use mobile phones, navigation or other electronic products, or eat, drink, talk, listen to music broadcasts and other behaviors, which can easily distract the driver and cause driving distraction and induce traffic accidents. In the state of distracted driving, the driver's awareness of potential conflicts in the vertical and horizontal directions decreases, which affects the driver's safe operation of the vehicle. For example, the reaction time of mobile phone calls and text messages to the driver's response ...
