Adaptive Front Lighting System: Other Hyundai Genesis I рестайлинг

Adaptive Front-lighting System (AFLS)

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.

Component of AFLS

1. Input part: It is provided that information of speed sensor, height sensor and so on related to condition of vehicle.
2. Control part (AFLS Unit): It controls Output part by analyzing/judging Input signal.
3. 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.

Main function of AFLS

Advantage of AFLS

Scheme 17

1. General System initialization, In case of input Engine signal (AFLS ECU, Levelling/Swivelling motor) Adaptation of AFLS OFF switch AFLS operate normally, only under turning low beam switch on. Providing Tell-tale function of AFLS (display 'AFLS OFF' on dashboard) In case of system failure, display blinking 'AFLS OFF' on dashboard.
2. Main function Swivelling function Levelling function Processing signal of Height sensor (Air suspension)

Scheme 18

1. General communicate AFLS Unit through LIN protocol Robust control to Disturbance Doesn't work out of rated voltage range.
2. Main function & Rating Drive Low beam to left/right side Fail-safe function: In case of detecting malfunction or system failure, drive to secure position gear ratio (150: 1) Operating voltage: 10V ~ 16V Operating current: 100mA

Scheme 19

1. Main spec communicate AFLS Unit through LIN protocol Robust control to Disturbance Doesn't work out of rated voltage range.
2. Main function & Rating Drive Low beam to upper/lower Fail-safe function: In case of detecting malfunction or system failure, drive to secure position Drive type: Micro step mode (1/16) Operating voltage: 10V ~ 16V Operating current: 100mA

Scheme 20

1. General Height Sensor connecting body & suspension measures inclination information from load condition. Vehicle having the Air-suspension system transmits inclination signal to AFLS ECU by using CAN protocol. Vehicle having the Steel-suspension system transmits inclination signal to AFLS ECU by using Hard-wire.
2. Rating Rated Voltage: 5V ± 5%

AFLS Fail-safe function

If the error condition of AFLS occurred during system operation, the system have to fail-safe reaction for prevent dazzling of opposite side driver

AFLS Fail-safe Index

AFLS Setting Procedure

When it replace AFLS ECU, H/Lamp Unit, Height sensor, it operates in setting procedure by using Diagnostic equipment following belows.

Parameter is composed of three state (Air-suspension, Steel-suspension, Delivery state)

When AFLS setting procedure operate, necessarily confirm suspension type and then download parameter.

Scheme 21

DTC: Diagnostic Trouble Code

DBL: Dynamic bending Light

HLL: Head Lamp Leveling

Vehicle condition while AFLS setting

1. Vehicle on an even surface
2. No vehicle movement
3. Gear position in P & N
4. Ignition switched on & Engine RPM >500RPM
5. Diagnostic equipment connected
6. ALL ECUs on CAN mounted and activated
7. Battery voltage > 10.5 V (ECU supply to be ensured)
8. Light switched
9. AFLS on (Don't push AFLS OFF switch)

Action in case of download wrong parameter

1. In case Steel suspension vehicle downloaded Air-suspension parameter B1638 (Air-Sus. CAN Signal Timeout) occurred
2. In case Air-suspension car downloaded Steel suspension parameter B1907 (FRT Sensor signal Fault), B1909 (Rear Sensor signal Fault) occurred
3. Solution Download Delivery Parameter check up B1661 (Parameter missing) Ignition OFF Ignition ON & Engine RPM > 500RPM Download matching Paratmer (Steel & Air suspension) In case download steel suspension parameter, Calibration have to operate up to setting procedure

AFLS Unit (ECU)

AFLS located in Cockpit Module is provided information of vehicle (steering wheel signal, vehicle speed, inclination of vehicle). Based on provided information, it calculates algorithm and adjust Low beam of H/Lamp.

It transmits driving information by using LIN protocol, it is operated in Fail-safe reaction mode In case system failure occurred.

Swivelling Actuator

Swivelling actuator inside H/Lamp is provided driving information of left/right side by using LIN protocol from AFLS Unit (ECU). It dirve to control position by using step motor.

In case of system failure, it provides function to back to initial position (center).

Levelling Actuator

Levelling actuator inside H/Lamp is provided driving information of upper/lower by using LIN protocol from AFLS Unit (ECU) It dirve to control position by using step motor.

In case of system failure, it provides function to lower to -2.8% or -1.5% position.
