Kia Optima Hybrid: Auto Head Lamp Leveling Device / 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 2° 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.
Components
1.
Auto head lamp leveling unit
1. Leveling unit & sensor
2. Sensor mounting bracket
3. Sensor linkage

Using a Micro-processor, percept the operation lever''s mechanical angle change or speed signal.
As an actuator control device of inner control program, mounting on the rear center arm.
2.
Actuator
Change the head lamp lighting direction up or down since automatic head lamp leveling unit sensing the input signal following the vehicle''s statically changes.
