Hyundai Santa Fe: Auto Head Lamp Leveling
Unit. Description and Operation
Description
According to driving environment and loading state of vehicle,
head lamp lighting direction is changed to keep the driver's visibility range
and to protect the driver's vision from glare, aiming at safety driving.
Sensor integrated ECU mounting on the rear center arm drives
the actuator mounting on the head lamp since sensing the input signal following
the vehicle's statically changes.
Head lamp beam is automatically operated by chassis tilt.
Operation
Operating Procedure
| 1. |
Suspension angle change resulted from vehicle's load
change.
|
| 2. |
Sensor angle change.
|
| 3. |
Microprocessor calculates necessary head lamp angle
change amount.
|
| 4. |
Sending a proper signal to head lamp leveling device
and driving actuator.

Operating Condition
| 1. |
Ignition on
|
| 2. |
Low beam on

| 3. |
On stop : If sensor lever change is 0.3° and above,
head lamp is operated after max. 1.5 sec.
|
| 4. |
On driving : If vehicle velocity is over 4km/h(2.48mile/h),
velocity change is not over 0.8-1.6km/h(0.5 ~ 1.0mile/h) per second,
and loading condition is changed, then head lamp is operated.
