Function
The beam direction of headlights is automatically
controlled according to driving conditions as
described in the table below.
Vehicle condition Control content
When parking The headlight automatic leveling ECU calculates the vehicle pitch
angle from the height sensor values according to the change in load
resulting from getting on/off or loading/unloading to control the beam
direction.
When driving at a constant speed When a vehicle starts on curb, the traveling vehicle posture changes
from the posture during parking, so that the beam direction changes.
To control the improper beam direction caused by such vehicle posture
change, the headlight automatic leveling ECU calculates the vehicle
pitch angle based on the average of height sensor values obtained for
12 seconds after the vehicle speed becomes constant. This beam
direction control while driving at a constant speed is performed only
once between a vehicle stop and the next stop. If driving is started at
a constant speed on the gravel or rough road, to prevent unnecessary
control resulting from detection of road uneven surface, the beam
direction control is launched after the driving speed becomes constant
on pavement.
