Auto Headlamp Leveling Device - Hev: Other Kia Optima III

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.

1. Auto head lamp leveling unit Leveling unit & sensor Sensor mounting bracket 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.
