BYD SEAL 2023 - Blind Spot Assist (BSA); Blind Spot Detection System

●
Situa
tions that may result in detection
failure of mmWave radars or late
alarms include, but are not limited to:
●
MmWave radar(s) come o󽗈, are
loosely installed, or are blocked.
●
The vehicle is running under extreme
weather, such as rain, snow, or smog.
●
The vehicle encounters certain metal
guardrails or similar road conditions.
WARNING
●
ELK
A serves as a driving
assistance function only, so the
driver is fully responsible for
driving safety.
●
In󽗊uence of weather, road
conditions, and other factors may
cause ELKA to fail.
●
Use ELKA based on your needs,
tra󽗋c, and road conditions.
Blind Spot Assist (BSA)
●
The blind spo
t assist (BSA) system
includes blind spot detection (BSD),
rear cross tra󽗋c alert (RCTA), rear cross
tra󽗋c braking (RCTB), rear collision
warning (RCW), and door open
warning (DOW). It detects environment
behind the vehicle through radars
installed on both sides of the rear
bumper so as to remind the driver of
safe driving.
Blind Spot Detection (BSD)
At vehicle speeds between 15-150 km/h,
if a rear corner mmWave radar detects
a vehicle in blind spots on an adjacent
lane or a vehicle approaching quickly on
the adjacent lane, the indicator on the
corresponding side mirror lights up. If the
turn signal for the same side is turned on
at this moment, the alarm indicator on
the side mirror 󽗊ashes t
o alert the driver
of a risky lane change.
Rear Cross T
ra󽗋c Alert (RCTA)
When the vehicle is reversing at a speed
no more than 15 km/h, the RCTA system
detects the vehicles traveling in the blind
spot at the back through rear corner
mmWave radars. If the system judges that
a vehicle approaching from behind poses
a risk of collision, the side mirror warning
indicators 󽗊ash and an audible alarm is
given to alert the driver, reducing the
possibility of collision.
Rear Cross Tra󽗋c Braking (RCTB)
When the vehicle is reversing at a speed
no more than 9 km/h, the RCTB system
detects the vehicles traveling in the blind
spot at the back through rear corner
mmWave radars. If the system determines
that a vehicle approaching from behind
poses a risk of collision, it performs
emergency braking automatically.
Rear Collisions Warning (RCW)
At vehicle speeds between 5 km/h and
146 km/h, if the rear corner mmWave
radar detects a risk of collision with a
vehicle approaching quickly from behind
on the current lane, the hazard warning
light turns on to warn the driver in that
vehicle against a possible collision.
Door Open Warning (DOW)
DOW is realized with rear corner mmWave
radars installed on both sides of the rear
bumper. When the vehicle is stationary
