The invention discloses an early warning method and early warning device based on driving distraction state, comprising the following steps: 1) acquiring traffic conditions and road conditions around the vehicle and identifying the driver's driving behavior; If not, go to step 3); if yes, go to step 4); 3) judge whether to deviate from the lane based on the traffic conditions and road conditions around the vehicle, if not, do not issue an early warning, and end the current round of early warning; if For deviation, the driver will be prompted by voice, and the current round of early warning will end after the prompt is over; 4) Predict the type of collision and lane departure that will occur, and perform a corresponding level of early warning based on the predicted situation. The early warning device and early warning method based on the driving distraction state of the present invention judge the risk level of the current driving behavior based on the driver's driving state, driving environment and vehicle attitude information, and can perform early warning according to the driver's reaction state to avoid traffic accidents .
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 ...
