Device and method for improving vehicle meeting safety performance

Abstract

The invention belongs to the technical field of vehicle meeting safety, and discloses a device and method for improving the vehicle meeting safety performance. The device for improving the vehicle meeting safety performance comprises a vehicle-mounted CAN bus, a single-chip microcomputer, a data processing unit, a rearview mirror, a vehicle speed sensor, a steering wheel angle sensor, a brake pedal stroke sensor, a laser scanning radar, a camera and a rotation motor, wherein the laser scanning radar is fixedly installed in the right middle of a front bumper of a vehicle, the camera is used for collecting images of the head of a driver, and the rotation motor is used for rotating the rearview mirror. The laser scanning radar faces the position in front of the vehicle, the output end of the vehicle speed sensor is electrically connected with the vehicle-mounted CAN bus, the signal input end of the data processing unit is respectively and electrically connected with the vehicle-mounted CAN bus, the laser scanning radar, an I / O interface of the single-chip microcomputer, the output end of the steering wheel angle sensor and the brake pedal stroke sensor, the signal output end of the data processing unit is electrically connected with the control end of the rotation motor, and the single-chip microcomputer is electrically connected with a video line of the camera through a USB interface.

Description

technical field [0001] The invention belongs to the technical field of vehicle meeting safety, and in particular relates to a device and method for improving the vehicle meeting safety. Background technique [0002] When a car suddenly encounters an oncoming car on a narrow road, the driver usually brakes to slow down and turns right to give way and meet cars safely. At this time, the driver usually judges the position of the vehicle and estimates the space on the right side of the road by observing the right rearview mirror and the front view, so as to determine whether the direction to the right is appropriate, and constantly adjust in the process . However, since the right side rearview mirror is mainly used to help the driver observe the lane conditions on the right rear side of the vehicle during normal driving, it is not possible to obtain the road boundary information corresponding to the vehicle body. At this time, because of the narrow road and the need for passin...

AI Technical Summary

Problems solved by technology

Therefore, at this time, the driver often misjudges and misoperates because the driver cannot obtain the information on the distance between the right side of the vehicle body and the right boundary of the lane. , unable to achieve safe car meeting; second, the vehicle leans too far to the right, causing the vehicle to cross the right boundary of the road, ride on the right curb of the road, or even rush out of the road

This makes meeting in this situation dangerous and inefficient
