Adaptive high beam control system based on LED light source

1 Introduction

It is often necessary to switch between far and near light when driving a car at night or when overtaking to ensure safe driving. Frequent far and near light switching requires higher driver speed and reduces driving comfort. The adaptive driving beam (ADB) control system of Hengrun Technology collects environmental variables through sensors such as cameras, and judges and controls through the algorithm controller to realize automatic control of the high beam system. The adaptive high-beam control system based on LED light source adopts more flexible LED module light source, realizes adaptive switching of multiple light types by controlling the brightness of single or multiple LEDs, and improves driving on the basis of ensuring driving safety. Comfort.

2. System composition

The adaptive high beam control system based on LED light source mainly includes:

♦ Camera unit

♦ Algorithm controller

♦ LED driver module

At the same time, the adaptive high-beam control system based on LED light source uses CAN bus technology to communicate quickly between the vehicle network-algorithm controller-LED driver module to ensure the real-time response of the system.

3. Main functions

The main functions of the adaptive high beam control system are:

• Automatic near and far light switching

When the vehicle's driving environment meets the conditions, the adaptive high beam control system will automatically turn on the high beam to enhance the ambient lighting, so that the driver can get a good driving view. According to the change of the driving environment in real time, the near and far light switching is performed.

• Anti-glare car & car

When the high beam turns on the vehicle to follow the car or the car, the adaptive high beam control system collects information through the camera for calculation, and controls the corresponding LED particles of the high beam module to be darkened or extinguished, changing the light type, and avoiding other road users. Causes dazzling while getting better road lighting.

• Pedestrian reminder

When a pedestrian is detected in front of the vehicle, the adaptive high beam control system alerts the driver and pedestrians by flashing lights to ensure driving safety.

4. Features

♦ Adaptive high beam control makes car lighting smarter and safer

♦ Flexible LED module control for improved lighting comfort

5. Summary

After years of research and development and road test, the adaptive high-beam control system based on LED light source developed by Hengrun Technology has complete solutions and stable system performance. It cooperates with North American Ford and OSRAM, and has obtained many including Great Wall and Beiqi. OEM project. Our efforts make car driving safer and more comfortable.
