Abstract

One object of the present invention is to provide a headlight control system. The headlight control system is configured to be used with a headlight of a vehicle. The headlight control system includes a first light sensor, a microcontroller, a first driving motor and an optical lens module. The optical lens module is disposed in front of the headlight to receive illumination of the headlight. The microcontroller is electrically connected to the first light source sensor and configured to receive a signal transmitted by the first light sensor. The first driving motor is electrically connected to the microcontroller. The first driving motor is configured to follow an instruction from the microcontroller to drive a first driving mechanism. The first driving mechanism is configured to adjust the optical lens module upon being driven by the first driving motor.

Claims

1. A headlight control system, comprising:

a first light sensor;

an optical lens module disposed in front of a headlight of a vehicle in order to receive illumination of the headlight;

a microcontroller configured to receive a signal of indicating an increased luminous flux detected by the first light sensor;

a first driving motor electrically connected to the microcontroller and following an instruction from the microcontroller to drive a first driving mechanism to adjust the optical lens module;

a power module electrically connected to the microcontroller and the headlight; and

a second light sensor electrically connected to the microcontroller;

wherein when a value of a luminous flux received by the second light sensor is less than a first luminous flux value, the power module powers the headlight;

wherein the first driving motor is instructed to drive the first driving mechanism to adjust an angle of the optical lens module to turn an irradiation angle of the headlight into a low beam mode when the microcontroller receives the signal.

2. The headlight control system of claim 1, wherein the microcontroller is further configured to receive a speed value detected by a velocity sensor of the vehicle, and the first driving motor is instructed to drive the first driving mechanism to adjust an angle of the optical lens module to turn an irradiation angle of the headlight into a high beam mode when the detected speed value is higher than a first speed value.

3. The headlight control system of claim 1, wherein the first driving mechanism is configured to use a multi-stage approach for adjusting the optical lens module.

4. The headlight control system of claim 1, wherein the first driving motor is a stepper motor.
