AFLS(Adaptive Front-lighting System）is a headlamp orientation control system that takes into account both steering angle and vehicle speed to orient the headlamps to an angle that provides better nighttime visibility.
Variable conditions make beam pattern of running vehicle kaleidoscope.
Input part : It is provided that information of speed sensor, height sensor and so on related to condition of vehicle.
Control part (AFLS Unit) : It controls Output part by analyzing/judging Input signal.
Output part : It drive Low beam of H/Lamp to upper/lower and left/right side optimum beam pattern according to output control signal of AFLS Unit.
Content | Description | |
1 | Dynamic Bending (Swivelling) | ● Providing optimum beam pattern in the curve road 1. Enhanced visibility in the curve road 2. Drive Low beam to left / right side |
2 | Automatic Leveling (Leveling) | ● Compensating Low beam according to inclination of vehicle 1. Compensation according to static condition (Load) 2. Compensation according to dynamic condtion (Quick start, Sudden stop ) |
3 | Fail-safe | ● Fail-safe reaction while detecting system failure and malfunction 1. Detecting signal / communication error for Swivelling 2. Detecting signal /communication error for Leveling 3. Detecting system failure |
Content | Description | |
1 | Enhanced stability | ● Visibility Guarantee In case of curve road ● According to vehicle Speed/Steering angle, speed/angle of Swivel actuator is automatically controlled to provide optimum beam pattern ● Fail-safe reaction application for Driver on opposite side road →In case error communication,automatically return initial position of Swivel actuator |
2 | Enhanced convenience | ● AFLS operating application by driver's selection(AFLS Off switch) ● Providing Diagnostic function for detecting system failure and malfunction and check up data information (by using Diagnostic equipment ) ● Reduced wiring-harness by Applying CAN/LIN communication in vehicle ● Fun Drving Function : Swivelling of Low beam → Increasing driver's pride |
General specification
AFLS System (AFLS ECU, Levelling /Swivelling motor) is initialized when the ignition signal is ON.
AFLS operates normally when the lighting switch is at the automatic position.
In case of system failure signal, ‘AFLS’ indicator is blinking on the cluster.
Main function
Operation and control for AFLS operation (leveling, swivelling)
Receiving the sensor signal.
Processing the sensor signal of height sensor.
Control the shield drum to change the beam pattern
Control the static bending light
Drive the head lamp low beam to left and right side to upgrade the visibility at the cornering road.
General specification
Swiveling motor is communicated with AFLS unit with LIN (Local Interconnect Network) communication.
Doesn't work out of rated voltage range.
Main function
Drive the head lamp low beam to left and right side.
Fail-safe function : In case of detecting the malfunction or system failure , the head lamp low beam move within the secure position.
Drive the head lamp low beam to up and down side to upgrade the visibility according to vehicle inclination.
General specification
Swiveling motor is communicated with AFLS unit with LIN (Local Interconnect Network) communication.
Doesn't work out of rated voltage range.
Main function
Drive the head lamp low beam to up and right down.
Fail-safe function : In case of detecting the malfunction or system failure , the head lamp low beam move within the secure position.
General specification
Height sensor is mounted between vehicle body and chassis and this sensors measure inclination information from load condition.
Vehicle with steel-suspension system transmits the inclination signal to AFLS unit by using Hard-wire.
Rating
Rated Voltage : 5V ± 5%
Change the beam pattern with rotating the shield drum (B).
Shield drum have 3 different patterns that are changed according to the driving conditions.
