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.

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.

The working principle of the invention is as follows:

the 360 ° safety surround view system: the method comprises the steps that 4 to 8 wide-angle cameras capable of covering all view field ranges around a vehicle are erected around the vehicle, multiple paths of video images collected at the same time are processed into a 360-degree vehicle body top view around the vehicle, the top view is displayed on a screen of a central console, real-time real-scene information around the vehicle body is collected by combining an ultrasonic sensor, the 360-degree all-around view around the vehicle is obtained, effective distance monitoring is carried out on obstacles in a sight blind area formed by the real-time real-scene information in the vehicle body in the processes of driving, backing and turning of the vehicle, and when a dangerous distance is monitored, image and sound alarm is carried out;

the vehicle body attitude sensor: when the vehicle body inclines, the information of the inclination angle of the vehicle body can be output as an electric signal;

the ECU controller: the electric signals input by the 360-degree safety panoramic system 1 and the vehicle body attitude sensor 2 can be converted into control over the rotation range of a motor for controlling the lamp;

the rotating electric machine is characterized in that: receiving a signal from the ECU controller 3, reacting to drive the lamp, and changing the irradiation angle of the lamp in the horizontal direction;

the stepping motor is characterized in that: receiving the pulse signal from the ECU controller 3, reacting to drive the lamp, and changing the irradiation angle of the lamp in the vertical direction;

FIG. 2 shows: the camera range of the safety system is looked around by 360 degrees, a plurality of paths of video images collected by the camera at the same time are processed into a vehicle body top view of 360 degrees around the vehicle through a system controller, and finally, a panoramic image is displayed on a central screen;

FIG. 3 shows: the irradiation angle of the headlamp when the vehicle is in normal running; the irradiation angle of the headlight of the vehicle under normal conditions is shown in FIG. 3, and the irradiation range of the headlight is observed when the vehicle ascends and descends as contrast;

FIGS. 4(a) to (b) show: when the vehicle goes up a slope, the irradiation angle of the headlamp and the irradiation angle of the vehicle posture sensor are adjusted according to the inclination angle of the vehicle body; from the figure, it can be seen that if the vehicle is not provided with the lighting follow-up system, a large light irradiation blind area exists when the vehicle goes up a slope; after the follow-up lighting system is arranged, the vehicle can obtain a good lighting range when going uphill. Thereby guaranteeing the driving safety and reducing the occurrence of safety accidents.

FIGS. 5(a) to (b) show: the irradiation angle of the headlamp and the irradiation angle of the vehicle posture sensor after being adjusted according to the vehicle body inclination angle when the vehicle is in a downhill state; from the figure, it can be seen that if the vehicle is not provided with the lighting follow-up system, a certain light irradiation blind area exists when the vehicle descends a slope; after the follow-up lighting system is arranged, the vehicle can obtain a good lighting range when going downhill.

FIGS. 6(a) to (b) show: when the vehicle turns, the ECU controller controls the headlamps to change the irradiation angle; it can be seen from the figure that when the vehicle is not equipped with the lighting follow-up system, the lighting angle of the light is consistent with the vehicle body when the vehicle turns, so that the road surface and the driving information in the curve cannot be obtained in advance, and when the vehicle is equipped with the follow-up lighting system, the road surface and the driving information in the curve can be obtained in advance when the vehicle turns, so that the speed of the vehicle is determined, and the countermeasures are taken in advance. Therefore, the driving safety can be better ensured, and the occurrence of safety accidents is reduced.

FIGS. 7(a) to (b) show: the irradiation angle is adjusted when the vehicle backs up. When a vehicle without the lighting follow-up system backs, the lighting angle of a reversing lamp is not comprehensive enough, and the vehicle is easy to scratch; if the follow-up device is also arranged in the reversing lamp, the illumination range can be greatly enlarged when reversing and turning, and the reversing is more convenient and safer.
