Lane departure early warning-based car outer airbag pre-starting system

Abstract

The invention discloses a lane departure warning-based car outer airbag pre-starting system which comprises an outer airbag device and a pre-warning system, wherein the pre-warning system comprises a video analysis unit which is arranged in the front of the car, a processing unit and a running state acquisition unit which is connected with a car bus in a communication manner; the video analysis unit is used for collecting the running line of the current lane; the running state acquisition unit is used for acquiring the angle and running speed of the guide wheels of the current car; the processing unit is used for judging the lane departure time of the current car according to the running line, the angles and the running speed, and controlling the outer airbag device to open when the lane departure time achieves a certain threshold. The lane departure warning-based car outer airbag pre-starting system is mature in technology, simple in structure and suitable for large-scale popularization and application, and has very important meaning for the safety of the car.

Description

technical field [0001] The invention relates to a vehicle exterior air bag pre-activation system based on lane departure warning. Background technique [0002] With the continuous development of the automobile industry, road traffic safety has received more and more attention. Now automobile airbags have become the standard configuration of most vehicles, effectively protecting the safety of drivers and members in various traffic accidents, and are in the process of continuous improvement. [0003] However, in the collision process of vehicles, the damage of vehicles, pedestrians and other vehicles is always inevitable. For example, in order to reduce the damage to pedestrians, the current vehicles have begun to talk about bumpers, fenders, engine covers and The trunk lid is made as soft as possible. Although it can achieve the purpose of protecting pedestrians very well, it also causes a decrease in the strength of the vehicle itself, causing heavy losses in collisions be...

AI Technical Summary

Problems solved by technology

Although it can achieve the purpose of protecting pedestrians very well, it also causes a decrease in the strength of the vehicle itself, causing heavy losses in collisions between the vehicle and other vehicles, such as heavy vehicles, passenger cars and trains, and due to the collapse of the vehicle structure, extremely Large squeezed the space of the members in the car, which led to the tragedy
