Multi-sensor detection vehicle right-turn blind area early warning system

Abstract

The invention discloses a multi-sensor detection vehicle right-turn blind area early warning system, which comprises a gyroscope installed in a vehicle and used for measuring the turning state of thevehicle in real time; an ultrasonic radar is installed in front of the right side of the vehicle and used for detecting the obstacle distance; the image sensor is mounted in front of the right side ofthe vehicle, captures and judges images of obstacles, distinguishes pedestrians, vehicles and static targets, and performs graded and strategy early warning; and the alarm is in signal connection with the gyroscope, the ultrasonic radar and the image sensor, and is used for judging data acquired by the gyroscope, the ultrasonic radar and the image sensor and sending out early warning. The systemis novel in structure, the situation of missed warning caused by the fact that a driver forgets to turn on a steering lamp is avoided, the mode of combining the ultrasonic radar and the image sensor is adopted, the obstacle target distance is monitored, graded and strategic early warning is achieved, real-time strain is achieved according to the current road condition, and the early warning accuracy of the right-turn blind area is improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a multi-sensor detection vehicle right-turn blind zone early warning system. Background technique [0002] The rapid development of automobiles has greatly facilitated people's travel and logistics transportation. In the world, automobiles are divided into two types: left-hand driving and right-hand driving. Taking side driving as an example, when the vehicle is turning right while the vehicle is running, the driver’s view of the right side of the vehicle is greatly limited, especially for large trucks, the height of the front of the vehicle affects the driver’s view of the road conditions on the right side of the vehicle. Judgment, so the right-turn blind spot warning system is extremely important. [0003] The current right-turn blind spot warning system usually judges the turning of the vehicle by collecting the vehicle turn signal signal, which is likely to cause o...

Problems solved by technology

[0003] The current blind spot right-turn warning system usually judges the turning of the vehicle by collecting the signal of the turn signal of the vehicle, which is likely to cause omission of the alarm strategy due to the driver forgetting to turn on the turn signal; at the same time, the current blind spot warning system for right turn has a single strategy, Unable to respond in real time based on current road conditions, and the accuracy of early warning is low
