A method of using a vehicle rear screen display system for prompting road conditions ahead

Abstract

The invention relates to a vehicle back screen display system for prompting road conditions in front and a use method thereof and belongs to the field of the automobile electronic technology. The system comprises a camera shooting mechanism in the front of a vehicle and a display mechanism on the rear portion of the vehicle. The camera shooting mechanism comprises three cameras arranged on the left side, the middle and the right side of the upper end of a cab respectively. The camera in the middle faces the front, and the left camera and the right camera face the left side and the right side respectively. The display mechanism comprises a left display screen, a middle display screen and a right display screen. The left camera, the middle camera and the right camera are connected with the left display screen, the middle display screen and the right display screen respectively. The cameras are provided with rotary seats and can vertically rotate along with the rotary seats. The back screen display system is provided with a master controller connected with a vehicle speed sensor of the vehicle, the master controller judges vehicle speed conditions to control the rotary seats to rotate or not, the cameras adjust camera shooting angles along with the rotary seats, the display angle of the system is larger, angle adjustment can be conducted according to different vehicle speeds, better visual directions are provided for vehicles behind, and the safety during lane change overtaking is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a vehicle rear screen display system for prompting road conditions ahead and a method for using the same. Background technique [0002] Cars often involve changing lanes and overtaking when driving on the road, but in the early stage of changing lanes and overtaking, the sight of the rear vehicles is blocked by the front vehicles, and it is especially easy to collide with vehicles in the opposite lane, and the probability of accidents is very high , and when there is a vehicle parked in the outer lane, the vehicle changing lanes behind and overtaking the vehicle is likely to collide vertically with the moving object in front of the stationary vehicle, which directly leads to the occurrence of accidents, and the incidence of fatal accidents is very high. Therefore, in order to reduce the occurrence of accidents To protect the life safety of individuals i...
