Kia Sorento: Description
BSD is a system that uses two magnetic wave radar sensors attached on
the rear bumper to measure the distance from the following vehicles and provides
the sensing and (visual and auditory) alarm of any vehicle coming into the blind
spot.
| - |
Blind Spot Detection (BSD) : Senses other high-speed access vehicles
in the blind spot and then displays a BSD warning lamp on the side mirror
for the driver.
Warning lamp and alarm is ON when driver turns on the turn signal
lamp to enter the lane where another vehicle is.
|
| - |
Lane Change Assist (LCA) : Senses other vehicles in the blind
spot and then displays a BSD warning lamp on the side mirror for the
driver.
Warning lamp and alarm is ON when driver turns on the turn signal
lamp without recognizing any sudden approaching vehicle from that direction.
|
System Operating Mode
| 1. |
When starting the engine with the switch off, OFF mode is on.
|
| 2. |
When pressing ON switch in OFF mode, Passive mode is on.
|
| 3. |
If starting the engine with the switch ON, Passive mode is on.
※ When IGN is ON, the switch is in the initial state : The last
position is kept.
|
| 4. |
If you start the engine with BSD switch ON, or if you turn on
BSD with BSD switch OFF, the warning lamp of the door mirror flickers
for 2 to 3 seconds.
This is to inform the driver that the BSD system is ready. (provided
that if the system is in Fail mode, there is no flickering.)
|
| 5. |
If the activation conditions (speed and curvature radius) are
met while driving, Active mode is on (warning issued).
|
| 6. |
If the activation conditions (speed and curvature radius) are
not met while driving, Passive mode is on (warning removed).
|
| 7. |
If BSD & LCA operation fails in any mode, Fail mode is on.
|
| 8. |
If BSD & LCA operation operates normally in Fail mode, OFF mode
is on.
|
| 9. |
If pressing OFF switch while BSD & LCA function is operating (Active/Passive),
OFF mode is on.

Warning Condition
| 1. |
Warning zone
|
| 2. |
Conditions for BSD warning ON
 The entire body of the target vehicle
is located behind the line A. Any part of the target vehicle pass the
line B. Any part of the target vehicle passes
the line D and Hysteresis In. The entire part of the target vehicle
passes the line D and Hysteresis In.
|
| 3. |
Conditions for BSD warning OFF
The entire body of the target vehicle
moves before the line A. The entire body of the target vehicle
moves behind the line B. The entire body of the target vehicle
passes the line D and Hysteresis Out. The entire part of the target vehicle
passes the line E and Hysteresis Out.
|
| 4. |
Conditions for LCA warning ON
The entire body of the target vehicle
is located behind the line B. Any part of the target vehicle pass the
line C. Any part of the target vehicle passes
the line D and Hysteresis In. The entire part of the target vehicle
passes the line E and Hysteresis In. In the all above condition, TTC(Time
to Collision) is not less than 4.5 sec.
|
| 5. |
Conditions for LCA warning OFF
The entire body of the target vehicle
is located before the line B. The entire body of the target vehicle
pass the line C. The entire body of the target vehicle
passes the line D and Hysteresis Out. The entire body of the target vehicle
passes the line E and Hysteresis Out. In the all above condition, TTC(Time
to Collision) is not more than 4.5 sec.
|
| 6. |
Sensor activation conditions
BSD & LCA switch (indicated by the switch
LED) is on. Vehicle Speed: 30 km/h or faster Curvature radius: 170m or more Relative car speed: -10 ~ 250㎞/h
("-" means overtaking the preceding vehicle)
|
| 7. |
Sensor deactivation conditions
BSD & LCA switch (indicated by the switch
LED) is off. Vehicle Speed: 28 km/h or slower Curvature radius: 150m or less Relative car speed: All except -10 ~
250㎞/h
("-" means overtaking the preceding vehicle)
|
| 8. |
System control prohibition
The radar is covered by debris: System
conditions - Blockage message is outputted
The radar installation is damaged by
an outside shock: Send the error code BSD & LCA system fails: Send the error
code The radar is overheated: System conditions
- Over Temperature message is outputted. |

Diagnosis With GDS
1.
BSD system defects can be quickly diagnosed with the GDS. GDS
operates actuator quickly to monitor, input/output value and self diagnosis.
