Distraction monitoring triggering type vehicle collision early warning system and control method

Abstract

The invention discloses a distraction monitoring triggering type vehicle collision early warning system and a control method. The distraction monitoring triggering type vehicle collision early warningsystem comprises a vehicle operation information detection unit, a data processing unit, a control execution unit and an attention signal monitoring unit. The attention signal monitoring unit and thevehicle operation information detection unit transmit measured data to the data processing unit, the data processing unit sends an instruction to the control execution unit, and the control executionunit executes alarming and braking. The attention signal monitoring unit carries out real-time video monitoring on the body of a driver and transmits information to the data processing unit. According to the invention, the driving state is monitored in real time; active early warning is carried out on driving safety in advance, negative effects caused by misjudgment of a driving assistance function can be avoided, collision risk calculation and secondary early warning or emergency braking are carried out by collecting vehicle operation data, the accuracy of collision early warning can be further improved, driving safety is guaranteed, and the traffic accident rate is reduced.

Description

technical field [0001] The invention relates to a vehicle early warning system and a control method, in particular to a vehicle collision early warning system and a control method triggered by distraction monitoring, and belongs to the field of automobile control. Background technique [0002] Distracted driving has adverse effects on traffic safety. According to the definition of the International Organization for Standardization (ISO), driving distraction refers to a phenomenon in which attention is directed to activities that are not related to normal driving, resulting in a decrease in driving performance. Inattention caused by the driver's deviated vision or distraction is a common and important cause of traffic accidents, especially in rear-end collisions. Although with the development of the current intelligent vehicle driving assistance system, it can provide early warning of vehicle collision, but the current anti-collision early warning system is based on the anal...

Problems solved by technology

The existing collision warning system is passive to carry out collision warning. When a collision risk actually occurs, it will produce obvious frustration, affect the handling comfort of the vehicle, and even cause the collision to be unavoidable because the collision crisis occurs too suddenly, resulting in The collision loss of the vehicle even endangers personal safety
