Description

Technical Field

[0001] The present invention relates to the technical field of vehicle management, and in particular to a vehicle light control method and system. Background Art

[0002] The lighting control of existing vehicles is generally based on the sensing signal of the light sensor. The light sensor is arranged on the top of the front windshield of the whole vehicle. When entering a tunnel, the light sensor does not sense the light change and the headlights are not turned on. This will cause the driver to experience a brief visual darkness at the moment of entering the tunnel. If there are vehicles or people in the tunnel at this time, the driver will not be able to visually discover them, which may lead to safety accidents or hidden dangers.

[0003] There are also methods in the prior art that do not use light sensors. For example, Chinese invention patent CN108621913A discloses a control system for turning on the headlights of a vehicle before entering a tunnel. The front camera collects images of road conditions in front, and then the signal processor processes the image. When it senses that there is a tunnel ahead, the headlights can be turned on in advance before the vehicle enters the tunnel. The above solution is based on the image information of the front camera and is only used to control the headlights. It cannot serve as a reminder to the vehicle behind during the process of entering and exiting the tunnel, and may cause problems such as rear-end collisions. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a vehicle light control method and system, which utilizes the photosensitive elements inside the front and rear cameras to control the turning on and off of the vehicle lights, replacing the light sensor, thereby ensuring driving safety and reducing costs.

[0015] As a further implementation, the acquisition of the rear ambient light information is configured as follows:

[0016] Acquire the ambient light information at the rear of the vehicle when the vehicle exits the tunnel.

[0017] As a further implementation manner, rear ambient light information is acquired, and in response to the rear ambient light information indicating that the light is dimming, the taillights are kept turned on.

[0018] In a second aspect, an embodiment of the present invention further provides a vehicle light control system, comprising:

[0019] The first photosensitive element is built into the front camera and is used to sense the ambient light at the front of the vehicle;

[0020] The second photosensitive element is built into the rear camera and is used to sense the ambient light at the rear of the vehicle;

[0021] The logic controller is used to receive the front ambient light information sent by the first photosensitive element and the rear ambient light information sent by the second photosensitive element, and control the opening and closing of the headlights and taillights according to the information.

[0022] As a further implementation, the logic controller is configured as:

[0023] Control the headlights and taillights to turn on when the ambient light information at the front of the vehicle indicates that the light is dimming;

[0024] When the ambient light information at the front of the vehicle indicates that the light is getting brighter, the headlights are controlled to be turned off;

[0025] Control the taillights to turn off when the ambient light information at the rear of the vehicle indicates that the light becomes brighter.

[0026] In a third aspect, an embodiment of the present invention further provides an electronic device, comprising a memory and a processor, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the vehicle light control method is implemented.

[0027] In a fourth aspect, an embodiment of the present invention further provides a computer-readable storage medium, which implements the vehicle light control method when the computer program is executed by one or more processors.

[0028] The beneficial effects of the present invention are as follows:

Through the above-mentioned control of the headlights and taillights, the vehicle lights can be turned on and off quickly, and at the same time serve as a reminder to the following vehicles to ensure driving safety.

[0030] The present invention utilizes the photosensitive element inside the camera of the whole vehicle. When the front end of the vehicle enters the tunnel, the front camera senses that there is insufficient light inside, and simultaneously activates the fill light function of the camera and turns on light signals to the headlights and taillights, thereby turning on the lights. There is no need to install additional light sensors, which reduces the demand for photosensitive elements in the vehicle and can control costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 is a flow chart of a control method according to one or more embodiments of the present invention;

[0033] Figure 2 is a block diagram of a control system according to one or more embodiments of the present invention. DETAILED DESCRIPTION

[0034] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0035] Embodiment 1:

[0036] This embodiment provides a vehicle light control method, such as Figure 1 As shown, including:

[0037] Acquiring front ambient light information, and in response to the front ambient light information indicating that the light is dimming, turning on the headlights and taillights;

[0038] Acquire the front ambient light information, and in response to the front ambient light information indicating that the light becomes brighter, turn off the headlights; and simultaneously acquire the rear ambient light information, and in response to the rear ambient light information indicating that the light becomes brighter, turn off the taillights.

[0039] The vehicle light control method of this embodiment is suitable for scenarios where a vehicle enters or exits a tunnel. The ambient light at the front of the vehicle is sensed by the photosensitive element of the front camera, and the ambient light at the rear of the vehicle is sensed by the photosensitive element of the rear camera. By using the photosensitive element inside the vehicle camera instead of the light sensor, the vehicle's demand for photosensitive elements can be reduced and costs can be controlled.

[0040] The specific control methods are:

[0041] When the vehicle enters a tunnel, the built-in photosensitive element of the front camera recognizes that the light is getting darker and transmits the light change signal to the logic controller. The logic controller receives the signal and powers the headlights and taillights according to the preset light-on method, turning on the headlights and taillights. Compared with traditional light sensors, it can turn on the lights 1 to 3 seconds earlier, increasing the speed of turning on the lights when the vehicle enters a tunnel.

[0042] When the vehicle exits the tunnel, the built-in photosensitive element of the front camera recognizes that the light is getting brighter, and transmits the light brightening signal to the logic controller. The logic controller receives the signal and turns off the headlights according to the preset light-off method. At the same time, the logic controller identifies the light signal recognized by the built-in photosensitive element of the rear camera. If the light becomes dim, the logic controller controls the taillights to remain on; if the light becomes brighter, the logic controller controls the taillights to be turned off.

[0043] This embodiment recognizes light changes through the photosensitive element of the camera, and controls the headlights and taillights according to the recognition conditions of the front and rear photosensitive elements, which can ensure that the lights are turned on and off in time; and this embodiment turns on the taillights when entering a tunnel and turns them off when exiting a tunnel, which can serve as a reminder to the following vehicles and ensure driving safety.

[0044] Of course, the vehicle light control method of this embodiment can also be applied to other scenarios:

[0045] When the vehicle is driving in the sunset, the built-in photosensitive element of the front camera recognizes that the light is getting darker and transmits the light change signal to the logic controller. The logic controller receives the signal and powers the headlights and taillights according to the preset light-on method, so that the headlights and taillights are turned on. The logic controller will identify the light signal recognized by the built-in sensor element of the rear camera. If the signal light provided is also getting darker, the taillights will not be intervened.

[0046] When the vehicle passes street lights and oncoming running lights, the built-in photosensitive elements of the front camera and the rear camera recognize the light changes and transmit the light change signals to the logic controller. The logic controller receives the signals and, according to the preset judgment logic, compares the light source with the camera, recognizes that the light is lit at intervals or the light is dotted in the opposite direction, etc., and continues to send power-on signals for the headlights and taillights to achieve the purpose of only turning on the headlights and taillights.

[0047] Embodiment 2:

[0048] This embodiment provides a vehicle light control system, such as Figure 2 As shown, it includes a first photosensitive element, a second photosensitive element and a logic controller, wherein the first photosensitive element is built into the front camera to sense the ambient light at the front of the vehicle; the second photosensitive element is built into the rear camera to sense the ambient light at the rear of the vehicle. The logic controller is used to control the on and off of the headlights and taillights according to the ambient light information obtained by the first photosensitive element and the second photosensitive element.

[0049] For tunnel scenarios, when the vehicle enters the tunnel, the first photosensitive element recognizes that the light at the front of the vehicle becomes dim, and the logic controller controls the headlights and taillights to turn on; when the vehicle exits the tunnel, the first photosensitive element recognizes that the light at the front of the vehicle becomes brighter, and the logic controller controls the headlights to turn off; at this time, the logic controller will judge the light at the rear of the vehicle recognized by the second photosensitive element. If the light is still dimmed, it means that the vehicle has not completely exited the tunnel and the taillights are not turned off; if the light becomes brighter, it means that the vehicle has exited the tunnel and the taillights are turned off.

[0050] This embodiment realizes the control of turning on and off the vehicle lights through the cooperation of the first photosensitive element, the second photosensitive element and the logic controller, thereby improving the extended use scope of the camera function.

[0051] Embodiment 3:

[0052] This embodiment provides an electronic device, which includes a memory and a processor. The memory stores a computer program. When the computer program is executed by the processor, the vehicle light control method described in Embodiment 1 is implemented.

[0053] The memory mentioned in this embodiment may be a volatile memory or a non-volatile memory, wherein the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory; the volatile memory may be a random access memory (RAM).

[0054] The processor may be implemented in at least one hardware form of DSP (Digital Signal Processing), FPGA (Field-Programmable Gate Array), or PLA (Programmable Logic Array).

[0055] Embodiment 4:

[0056] This embodiment provides a computer-readable storage medium, and when the computer program is executed by one or more processors, the vehicle light control method described in Embodiment 1 is implemented.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
