Automatic High Beam
Control (AHBC)
The Automatic High Beam Control (AHBC)
system can automatically switch between
the high beam and the low beams at night.
The system uses the front camera to detect
the light source information, and
automatically switches between the high
beam and the low beam according to the
situation of the oncoming vehicle, the
vehicle ahead and the ambient light source.
Generally, this system automatically
switches the high beam to low beam when
the system detects the headlamps beam of
the oncoming vehicle, the taillights of the
vehicle ahead or other light sources are
detected, in order to avoid the glare of the
high beam from affecting other traffic users.
When the vehicle done meeting, overtaking
or there is no ambient light source around it,
the low beam of the vehicle will
automatically switch to the high beam.
Enabling and Activation of AHBC
At night, when the external light is set to
automatic in the multimedia display, move
the light control combination switch in A
direction for the first time to turn on the high
beam. Move the light control combination
switch in A direction for the second time to
activate the Automatic High Beam Control
(AHBC) system.
At night, after the front combination lamps
automatically turn on, the Automatic High
Beam Control (AHBC) system will activate
automatically.
After the Automatic High Beam Control
(AHBC) system is activated, the Automatic
High Beam Control (AHBC) system will turn
on the high beam automatically, if all
following conditions are met:
1. Vehicle speed ≥ 40 km/h;
2. No relevant traffic users or other light
sources are detected.
If any following conditions is met, the
Automatic High Beam Control (AHBC)
system will turn on the low beam
automatically:
1. Vehicle speed ≤ 20 km/h;
2. Relevant traffic users or other light
sources are detected.
When the Automatic High Beam
Control (AHBC) system has turned on
the high beam, and the vehicle speed
maintains at 20 ~ 40 km/h, the Automatic
High Beam Control (AHBC) system keep
the high beam on until a light source is
detected and the Automatic High Beam
Control (AHBC) will turn on the low beam
automatically.
