Abstract

A vehicle automatic lighting device is assembled on the vehicle and turns on the vehicle lights when the brightness outside the vehicle is insufficient. The automatic lighting device includes: an image capturer assembled on the vehicle and focusing upward on the sky, and an image recognizer receiving and analyzing the image captured and output by the image capturer. When the brightness in the image is insufficient, the image recognizer outputs an activation signal to drive the vehicle lights to be bright. The image recognizer is used to identify the grayscale value of the image of the sky captured by the image capturer to determine the brightness of the driving environment and automatically turns on the vehicle lights to prevent the driver from operating the vehicle light switch without paying attention to the road conditions and affecting driving safety.

Description

Vehicle automatic lighting device

technical field

The utility model relates to an automatic light-on device, in particular to an automatic light-on device assembled on a vehicle to automatically turn on the vehicle light when the brightness is insufficient.

Background technique

Generally, when the vehicle is moving, if the sky is getting dark or entering a tunnel, the driver can control the light switch to turn on the headlights in front of the vehicle to illuminate the road ahead and ensure driving safety. However, the setting position of the light switch is different for vehicles produced by different manufacturers. For example, when the vehicle is driving and does not know the vehicle conditions well, manipulating the light switch to turn on the headlights may cause the driver to be distracted and not pay attention to the vehicle. The current situation may affect driving safety.

Utility model content

The purpose of the utility model is to provide an automatic light-on device for a vehicle that can automatically turn on the lights of the vehicle when the brightness of the driving environment is insufficient.

The automatic light-on device of the vehicle of the utility model is assembled on a car, and the car has lights, and it is characterized in that the automatic light-on device includes: an image picker assembled on the car, and the image picker and the The vehicle light is electrically connected to the image recognizer, and the image recognizer receives and analyzes the image captured by the image capture device to control the vehicle light.

The beneficial effect of the utility model lies in: using the image recognizer to identify the gray scale value of the sky image captured by the image capture device, to determine the brightness of the driving environment, and to automatically turn on or turn off the car lights, so as to avoid the driver from manipulating the car Switching lights without paying attention to road conditions affects driving safety.

Description of drawings

Fig. 1 is the structural representation of the preferred embodiment of the automatic light-on device of the utility model vehicle assembled on the vehicle; and

Figure 2 is a block diagram of the preferred embodiment.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:

As shown in Fig. 1 and Fig. 2, the preferred embodiment of the automatic light-on device of the vehicle of the present invention is assembled on the vehicle 2, and activates the vehicle light 22 of the vehicle 2 when the brightness of the driving environment is insufficient when the vehicle 2 is moving. The vehicle lamp 22 in this embodiment is illustrated by taking the headlight at the front end of the vehicle 2 as an example, but the implementation is not limited to the type of the vehicle lamp 22 .

The automatic light turning device includes: an image capture device 3 assembled on the windshield 21, an image recognizer 4 assembled in the vehicle 2, and a light switch 5 for controlling power supply to the light 22 .

In this embodiment, the image capture device 3 is a camera, which is assembled on the inner surface of the windshield 21 of the vehicle 2 and focuses upwards on the sky to capture images of the sky. However, during actual implementation, the image capture device 3 only needs to be assembled in the vehicle 2, and focus upwards on Above the sky, the purpose of capturing images can be achieved, so the scope of implementation is not limited to the location where the image capture device 3 is assembled.

The image recognizer 4 receives and analyzes the image captured by the image capture device 3, and recognizes the grayscale value of the image. When the grayscale value in the captured image is lower than a predetermined value, it means that the brightness of the captured image is too low , the vehicle 2 may enter a tunnel or basement, or it is getting late and the driving environment is not bright enough, the image recognizer 4 immediately outputs an activation signal to the light switch 5 . After the light switch 5 receives the activation signal output by the image recognition device 4, it is turned on immediately to lead the power supply to the light 22, so that the light 22 is turned on to illuminate the road conditions ahead.

Relatively, when the vehicle 2 comes out of the tunnel or the basement, or when the sky is getting brighter in the early morning, the image recognizer 4 analyzes and recognizes that the grayscale value in the captured image is higher than the predetermined value, and the image recognizer 4 also outputs a stop signal to light switch 5. The car light switch 5 is just disconnected immediately and the car light is extinguished.

That is to say, when the vehicle 2 is running and the brightness of the driving environment is insufficient, the image capture device 3 will automatically drive the light switch 5 immediately, and the light 22 will be turned on to illuminate the road ahead without the need for the driver to control or search for the vehicle. Light switch 5, the driver can concentrate on the road conditions ahead, improve the safety of driving. When the brightness of the driving environment is sufficient, the image capture device 3 automatically turns off the vehicle lights 22 immediately.

In view of the above, the automatic light-on device of the vehicle of the present invention uses the image capture device 3 to capture the image of the sky, so that the image recognizer 4 can distinguish the gray scale value of the image to determine the brightness of the driving environment, and automatically turn on or turn off the vehicle. Light 22, in order to avoid the driver because of manipulating the car light switch 5 and not paying attention to road conditions and affecting driving safety, so the purpose of the utility model can indeed be achieved.
