Predictive Emergency
Braking System
The predictive emergency braking
system has two features: Predictive
Collision Warning (PCW) and Autonomous
Emergency Braking (AEB). This system
uses radar and multifunctional video
controller to detect with vehicles ahead
or pedestrians. When a risk of collision
is detected, the system will give a sound
alarm and light warning to alert the driver,
and improve the potential braking pressure
for better response timing. If the system
detects increased risk of collision, it will
automatically apply braking pressure to
assist in collision avoidance or reduce
impact.
To enable or disable the PCW function, tap
on → DiPilot → Active Safety. When the
vehicle is started, the system is switched on
by default.
PCW
PCW
• Safety distance warning
• If the vehicle is too close to the vehicle
ahead at speeds above 65 km/h for
too long, the system will give a safety
distance warning, and the indicator
on the cluster will light up.
• Pre-warning
• If the system identifies collision risk
at speeds between 30 and 150 km/h,
there will be a sound alarm and the
indicator will light up on the cluster.
• Emergency warning
• If the driver fails to respond to the
pre-warning, the system will give an
emergency alert. The indicator will
flash and there will be a short braking
warning.
AEB AEB
• If the driver fails to respond to the
emergency warning and the risk level
increases, the system will enable the
AEB function. The system will engage
braking force as much as possible to
avoid collision or reduce crash impact.
• If the driver applies insufficient braking
force in an emergency, the braking
system will provide additional braking
force to reach the optimal level required
to avoid collision or reduce crash impact.
System Limitations
• In some environments, detection may be
affected or delayed. If the target's radar
reflection area is too small (e.g. bicycle),
the system may not be able to establish
its distance, which results in either late
response or no response.
• In the following cases, the predictive
emergency braking system may be
affected or give no response:
• In rainy, snowy or foggy days, large
water splashes, or exposure to direct
sunlight or glaring lights.
• The sensor is dirty, hazy, damaged or
blocked.
• The radar fails under interference
from other radar sources, such as
strong radar reflection in multi-layered
parking areas.
• In complex traffic, the system may not be
able to properly respond to the following
circumstances:
• Pedestrians or vehicles moving too
quickly within the sensor's detection
range.
• Pedestrians obscured by other objects.
• Pedestrian outlines are
indistinguishable from the
background.
