MATRIX SEGMENT
Intelligent beam can also include added beam
projection to low beam and high beam ones.
MATRIX SEGMENT is a function to be activated
through specific scan tool through EOBD.
Usually all car manufacturer/EOM clearly
determines values to be respected in such a
projection position: check is linked to the position
in the horizontal deviation

7. UNDERSTANDING OF MEASURED VALUES.

The following Sections explain the most important
measurement quantities required for headlamp
adjustment.
Pitch angle
The definition of the pitch angle is illustrated in the
following.
Fig. 10.1 Pitch angle
- "H": Height of centre of headlamp measured
from the ground
- "H": Height of image projected by headlamp
at a distance of 10 m, measured from the
ground
- "ɛ": Pitch angle, calculated with the following
formula:
ɛ = [(H-h) / 1000] x 100

8.1 Ece European Standards

8.1.1 Low beam pattern

"A": bright-dim border, made up of two
sections:
Horizontal section, rising straight line, also
referred to as "shoulder". The bright-dim
border must be within the tolerance range
stipulated in the guideline.
"B": break point with asymmetrical light;
center point with symmetrical light.
"C": deviation of the break point in
vertical direction (also known as pitch
angle). The value is always shown as an
absolute value. Possible units:
%, cm / 10 m, degrees
"D": deviation of the break point in
horizontal direction. The value is always
shown as an absolute value. Possible
units:
%, cm / 10 m, degrees
"α": angle between the "shoulder" and
the horizontal section of the bright-dim
border (also referred to as yaw angle with
asymmetrical low beam).
- "β": angle between the left portion of the
bright-dim border and the horizontal (also
referred to as roll angle, usually 0°).
