Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the overall operation process of the system is as follows:

[0028] Step 1: Information collection. The photosensitive sensor collects the light intensity, as well as the voltage and current signals of the left and right headlights.

[0029] Step 2: Discrimination of lamp failure. The main control module detects and analyzes the voltage and current of the left or right headlight to determine whether the left or right headlight is faulty.

[0030] Step 3: Adjust the brightness of the surviving headlamp. If the main control module judges that the left headlight is faulty, then cut off the left power supply and increase the brightness of the right headlight; if the main control module judges that the right headlight is faulty, then cut off the right power supply and increase the Brightness of side headlights.

[0031] further, such ...

Abstract

The invention discloses a control method based on an LED self-adaptive headlamp, and provides a safe lighting method for adjusting a non-fault vehicle lamp lighting area under a single-side vehicle lamp fault. According to the safety lighting system of the automobile self-adaptive headlamp, whether the self-adaptive headlamp is in a fault state or not is judged according to changes of voltage and current of a left automobile lamp and a right automobile lamp of the self-adaptive headlamp. If the vehicle lamp on the left side of the self-adaptive headlamp system breaks down, that is, the vehicle lamp on the side is abnormal in voltage and current signals, the vehicle lamp breaks down through judgment of a main control module, and a normal lighting task is difficult to complete. The system determines that the left headlamp of the automobile is damaged, cuts off the power supply of the left headlamp, expands the illumination range of the right headlamp, and improves the illumination brightness. Through the steps, the night emergency lighting task can be well completed under the condition that one headlamp is damaged, and the safety of vehicle night driving is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle lighting, in particular to an adaptive automobile headlamp. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards. Cars are increasingly developing towards safety, comfort, and environmental protection. Focusing on the lighting system, people put forward higher requirements for the safety performance of automotive lighting, that is, good headlights should be able to provide safe lighting for cars driving at night. However, driving at night for a long time puts forward very high requirements on the durability of the car headlights. It is not difficult to find that the headlights of some vehicles are damaged on the road. If the vehicle is driving at night, the headlights on one side of the vehicle cannot Complete normal lighting tasks. As a result, the driver cannot see the road conditions ahead, and even a ...
