A car headlight adjuster is a device used to adjust the direction of the car headlight beam, mainly used to ensure the lighting effect and safety of the headlights during driving. The principle mainly includes the following aspects:
1.Sensor detection of vehicle posture: The car headlight adjuster uses the vehicle posture sensor to detect the vehicle's tilt angle and acceleration, and understand the vehicle's driving status. For example, when the rear of the vehicle experiences sinking due to excessive load, the regulator can detect this change through sensors.
2. Calculation and control of lighting direction: Based on the vehicle attitude information obtained from sensors, the adjuster determines the adjustment of lighting direction by calculating the control unit to maintain appropriate lighting effects. For example, based on the forward tilt angle of the vehicle body, the adjuster can adjust the headlight beam downwards in a timely manner to avoid discomfort and interference from other vehicle drivers caused by excessive lighting.
3. Adjusting the headlight beam: The adjuster adjusts the direction of the headlight beam through an electric drive mechanism to achieve appropriate lighting effects under different driving conditions. For example, when the vehicle is going downhill, the adjuster can automatically adjust the beam downwards, making it more focused on illuminating the road ahead, improving the lighting effect and visibility.
4. Driver manual control: In addition to automatic adjustment, some car headlight adjusters also have a manual adjustment function, allowing the driver to adjust the direction of the lights according to their own needs. This includes adjusting the tilt angle of the lights under different road conditions, weather conditions, or driving environments.
In summary, the car headlight adjuster detects the vehicle's tilt angle and acceleration through the body posture sensor, and adjusts the lighting direction through the calculation control unit to ensure appropriate lighting effects and safety. This provides drivers with a good driving view and reduces the risk of driving at night and in adverse weather conditions.
