When the blind spot assist system
●
is on standby, if vehicle conditions,
such as speed or gear status, do not
meet the requirements of any function,
is displayed on the instrument
cluster and blind spot assist will not be
activated.
If the blind spot assist system
●
malfunctions, is displayed on the
instrument cluster.
When the blind spot assist system is
●
active, is displayed, meaning that
the function has been activated and
can trigger alarms at any time.
Precautions
While the BSD system provides
●
assistance in monitoring blind spots of
rearview mirrors, it cannot replace the
driver's observation and judgement.
The driver must keep control of the
vehicle at all times and drive properly
and is fully responsible for the vehicle.
The BSD system may be unable to
●
provide adequate warning on target
vehicles approaching from behind at a
high speed.
The driver must ensure the normal
●
operation of the BSD system, keeping
its rear corner mmWave radars in good
condition. For example, dirt, snow, or
other obstructions need to be cleared
right away.
The BSD system gives a warning if
●
unrelated targets at the rear side or in
the rear (such as work zone barriers,
large roadside billboards, reflectors in
tunnels, or other objects with a large
radar cross section) are mistakenly
selected as target vehicles.
Detection may be affected or delayed
●
in some environments. If the radar
cross section of the target vehicle is
too small (a bicycle, electric moped or
pedestrian, for example), the system
may fail to identify targets, leading
to false alarms. In addition, detection
may also be affected or delayed by
noise or electromagnetic interference.
RCTB activation scenario:
●
A pedestrian is crossing behind the
●
vehicle when it is reversing at a low
speed.
System Limitations
The activation of the RCTB system
●
depends on various factors such as the
environment, the state of the vehicle
and the target. There is no guarantee
that the emergency braking can always
be activated in every scenario.
Under some circumstances, it is
●
difficult for the system to assist the
driver, and detection may be affected
or delayed. Possible circumstances
include, but are not limited to:
The vehicle coming from behind
●
changes the lane suddenly.
Vehicles coming from behind are
●
detected too late at sharp turns,
slopes, or other settings.
The target vehicle is obscured.
●
Vehicle coming from behind at a
●
relative speed above 49 mph (80
km/h).
The vehicle is on a curve which is
●
too sharp, or is entering or exiting a
curve.
The vehicle is running under severe
●
weather, such as rain or snow.
Rear corner mmWave radar(s) come
●
off, are loosely installed, or are
blocked.
The vehicle encounters certain metal
●
guardrails or similar road conditions.
