Abstract




This study evaluates the effects of the vehicle body
inclination changes on the cut-off (the transition between the lighter and
darker portions of the beam) vertical position of dipped beam which is one of
the main functions of the headlamp. The functionality of headlamp vertical
aiming system and its importance for the driving safety are examined. In case
of any change on the vehicle, which effects to the vehicle inclination values, a
control method is defined in order to check suitability of cut-off vertical
position for every loading conditions defined by regulations. In addition, the calculations
are formulated to find required vertical aiming values in order to keep the
cut-off position in the range of minimum to maximum values defined by the
regulations are formulated.




It is concluded that after heavy accessory/configuration
changes, major modifications, or new version of model aplications on the vehicle
make necessary to be checked availability of actual cut-off vertical positions
and output values of the headlamp aiming software. In case of aiming software
update necessities, new values based on regulated loading conditions can be
defined by following formulations.
