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 0.3° 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. |
Components
1. |
