Kia Carens: Auto Head Lamp Leveling Device / Auto Head Lamp Leveling Unit Description and operation
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.
Operating Procedure
1. |
Suspension angle change resulted from vehicle's load 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
3. |
On stop : If sensor lever change is 0.7° 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.

Description
Automatic transaxle control system relies on various measurement data to determine
the current control status and determine the necessary compensation values.
These values are used to control the actuators and achieve the desired control
output.
