Blind Spot Detection Radar System
24GHz radar blind spot detection system (hereinafter referred
to as BSD system) is a set of auxiliary system which uses
radar sensor to detect road traffic conditions and visual blind
spot area. It is to provide alert information for driver when
changing lanes. This blind spot monitoring system set range
includes both sides and the rear of the vehicle. The system will
provide different warning level to remind drivers based on the
message of indicator for changing lane once target enter the
blind spot zone.
Notice:
Blind spot detection system is not able to detect all the cars
in all cases. There is still the risk of accidents.
Blind spot detection system can not be used to replace the
judgment of driving on the road, do not place undue
reliance on detection results. For changing lanes or similar
operations, driver still needs to concentrate and observe
the surrounding environment.
If the rear car driving fast, blind spot detection system may
not react.
Blind spot detection system will start detection
mechanisms with car speed 10 km / h or more.
If the radar sensor system detects error, a warning light will
be turned on and maintained, this system will point out the
problem comes from left or right side of the sensor.
Radar and Warning System location
Blind spot detection system consists of two radar sensors and
a warning system

Radar sensors are installed in the rear bumper of the left and
right sides (such as schematic in Figure 1). The radars on the
two sides help drivers detect vehicles.
(Figure 1)
If the radar sensor is obscured, it may not detect obstacles and
reduce system performance. To avoid radar sensor function is
affected, please pay special attention to the following points:
Do not shield radar sensor foreign body parts (such as
stickers, bike rack, trailer).
Avoid bumper was hit or damaged, if the above situations,
such as shock or damage, please contact the service
center as soon as possible and repair.
Ensure that the soil/ snow or ice on the site of the radar
sensor has been cleared..
Warning system will be installed in the driver's seat and front
passenger side A-pillar (as shown in Figure 2).

Blind spot detection system startup and shutdown
Start up
After pressing the button, the button's indicator light is and the
system is turned on.
Shut down
Pressing the button again, the indicator on the button goes off
button and the system is shut down. When you turn off the
system, you will not receive alerts.
Blind spot detection system switch will remain in the
position you set.
Warning level
Blind spot detection system provides the driver lance change
assistance according to if driver uses indicator light when
changing lane.
Warning display is divided into two levels:
Level One Warning:
If you are on a normal driving lane and do not intend to use
light indicates to change lanes, blind spot detection system
only detects whether both sides would become a danger for
the car to change lanes. If the relative speed and relative
distance are considered to be hazardous for changing lane,
warning system on A pillar will provide light alert.
Level Two warning:
If you use indicator to change lane and the blind spot detection
system detects the danger from both sides, the warning
system will provide light and audio alert.

Level One and Level Two warning is to remind the driving
situation. Driver still needs to concentrate and observe the
driving conditions.
Detection range and warning systems
When you start the engine / ACC (TBD), the blind spot
detection system indicator will appear briefly lit and warning
beep sound to confirm that the system is functioning properly.
For automatic transaxle car, this system only works when
the S, D gear.
Blind Spot Detection System provides alert for driver
assistance (As shown in Figure A). when another vehicle from
behind goes into the blind spot area, referred to here as the
blind spot area extending from the sides of the vehicle around
the rearview mirror to a position about 3 meters away from the
bumper .
Blind spot detection system will active when the vehicle speed
exceeds 10km/h. Level one warning will be triggered when you
overtake or another vehicle comes from the front into the blind
spot area with relative speed equal or less 10km/h.
When the vehicle pass rapidly through the blind spot
region (The relative speed is greater than 60km/h, or
less than 2 seconds Time to Collision) will not trigger the
alarm.
Blind spot detection system does not have the ability to
measure the width of the lane. The system is based on a fixed
lane width to detect. The main detection range is the normal
driving lane which cover two adjacent lanes. It does not

consider driver is driving whether in the center of the lane or in
the edge of the lane.
If the driver rides in the narrow lane or does not in the center of
the road, the system may not provide alert for the vehicle
driving in adjacent lane (as shown in Figure B) based on Level
One and Two Warning.
When driving on a relatively wide lane, the blind spot detection
system may not detect the vehicle on the adjacent lane
because they are out of the observation range.
(Figure A)
Driving on normal lane width within the range of observation,
(Figure B)
When driving on narrow lanes, blind spot detection system
may react to the vehicle driving in adjacent lane.

Please note that the design of the blind spot detection
system is not used to avoid collisions with other vehicles
or objects. blind spot detection system cannot be sole
basis for for hanging lanes. Please keep driving carefully. This
system provides a warning only as a assistant tool to help you
to find the vehicle in blind spot area.
Radar detection limitation
In some cases, when the vehicle enters or leaves the blind
area it may cause improper detection.
The conditions are below:
Abnormal driving conditions
Mud, snow or ice deposits in the rear bumper which is on
radar sensor radiation area.
Vehicle pass through the blind spot area with high speed..
(Less than two seconds)
Radar detection sensitivity may be reduced suddenly
because of the rain, snow and splashes in a blind spot
detection system. The Blind Spot Detection System may
not detect timely or even miss detection to the car. Driver
needs to continue to maintain driving direction and carefully
observe the surrounding environment.
When multiple vehicles pass through the blind spot area
closely, it may not get alert for the following vehicle.
In narrow curve lane, the blind spot detection system can
not detect the car. When driving into the corners, it may get
Level One Warning for the oncoming vehicles in adjacent
lane.
If there is a short error, such as a car battery power is too
low, it may be temporarily unable to start the blind spot
detection system.
In the heavy rain or condition which may affect detection,
the radar sensor may not detect obstacles.

False alarms
In some cases, an warning occurs but there is no vehicles in
the blind spot area. In this case, the alarm is usually a
temporary error and the system will correct itself.
Conditions may cause false alarms are as follows:
Bush
Construction fence
highway concrete walls
Narrow road curve or arch
Sharp turn around the building
Guide barricade placed in high or misplaced
Road barricade
Equip with non-recognized trailer hitch: The system should
be close to avoid false alert if the trailer is used. For the
trailer hitch that is installed at the factory, as you plug
power to the trailer socket, blind spot detection system will
automatically open.
