Abstract
Provided is an Adaptive Front Lighting System and a control method thereof, which includes a motor driver which controls a beam irradiation direction of a headlamp by operating a motor coupled to the headlamp according to a motor control signal, and generates a motor fault signal when fail occurs in the motor, a power supply unit which controls a magnitude of electric power supplied to the headlamp according to a power control signal, and a controller which selectively outputs the power control signal to the power supply unit according to the motor fault signal of the motor driver.
Claims14
An adaptive front lighting system, comprising:
- a motor driver which controls a beam irradiation direction of a headlamp which includes a plurality of LED lamps, by operating a motor coupled to the headlamp according to a motor control signal, and generates a motor fault signal when fail occurs in the motor;
- a controller which selectively outputs a power control signal to turn off at least an LED lamp irradiating beam to a direction according to the motor fault signal of the motor driver;
- and
- a power supply unit which blocks an electric power supplied to the at least an LED lamp according to the power control signal.
A method of controlling an adaptive front lighting, the method comprising:
- a) sensing a motor fault signal of a motor coupled to a headlamp which includes a plurality of LED lamps in a dynamic bending mode of controlling a beam irradiation direction of the headlamp;
- and
- b) selectively controlling turn-off of at least an LED lamp according to a power control signal.
