Description
Technical Field
The invention belongs to the technical field of automobile engineering, and particularly relates to a follow-up lighting system based on a 360-degree all-round view safety system.
Background
When the automobile runs in a turn, particularly runs on an urban road without street lamps at night, the judgment of pedestrians or other obstacles on the curve by a driver is influenced due to the irradiation range of the headlamp, so that traffic accidents are caused, and life and property losses are caused.
Therefore, in order to enable a driver to accurately and timely obtain lighting information of a road ahead in a severe environment or during driving at night, a headlamp lighting System is required to continuously adjust the light irradiation angle along with the change of road condition information, and the headlamp lighting System is an automobile headlamp follow-up steering System (AFS for short).
However, the headlamps may still have a blind field of view if they are only turned horizontally. Such as: when the vehicle goes up a slope, when only the front wheels enter the slope and the included angle between the vehicle body and the ground is smaller than the angle of the slope, the headlamp can only irradiate a short distance ahead, and the headlamp irradiation distance is shorter when the angle of the slope is larger. When the vehicle runs downhill, when only the front wheel enters a ramp, the light is higher than the sight plane, so that the detailed condition of the road surface cannot be judged due to short distance and failure of light irradiation on the road surface. The following steps are repeated: when a vehicle turns, the body of the vehicle can incline to a certain degree, and the phenomenon is particularly obvious on a slope, so that certain deviation occurs in the illumination ranges of the left and right headlights of the vehicle; particularly, in a large truck, the inclination angle of the truck body during turning is larger, which causes much trouble to a driver and is very easy to cause accidents.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a follow-up lighting system based on a 360-degree all-round vision safety system, which has the characteristics of simple structure, elimination of a light irradiation blind area and guarantee of driving safety.

The vehicle all around be equipped with 4 wide angle cameras respectively, the camera with 360 all around look systems link to each other.
The front camera is fixed at the radiating fin below the vehicle head license plate; the rear camera is arranged at the radiating fin below the license plate of the vehicle tail; the left and right cameras are respectively arranged below the left and right rearview mirrors.
The invention has the beneficial effects that:
compared with the prior art, the invention adopts a 360-degree all-round-looking safety system, also called as a blind zone monitoring system (BSD), wherein the BSD is that a plurality of paths of video images collected at the same time are processed into a 360-degree top view of the vehicle periphery by erecting 4 to 8 wide-angle cameras capable of covering all the view field ranges around the vehicle, and finally the top view is displayed on a screen of a central control console, and real-time real-scene information around the vehicle body is collected by combining ultrasonic sensors (used for measuring the distance between the vehicle and surrounding obstacles) in the 360-degree all-round looking system, so that the 360-degree all-round looking field around the vehicle is obtained, and the obstacles in the blind zone formed by the real-time real-scene information are effectively monitored during the driving, backing and turning processes of the vehicle, and when the dangerous distance is monitored, image and sound alarm is carried out.
The image information collected by the camera is integrated in the display screen and processed into a 360-degree all-dimensional surrounding visual field, and the position of the lamp is adjusted by controlling the stepping motor and the rotating motor through the ECU controller in the area with insufficient light in the range of the blind area of the visual field in the processes of vehicle driving, backing and turning, so that the blind area of light irradiation is eliminated, and the driving safety is ensured.
