Description and Operation

Description

• Blind-Spot Detection (BSD): detects other vehicles in the BSD zone and displays the BSD warning light on the outside rearview mirror for the driver. The warning light flashes when the driver turns on the turn signal to enter the lane where the other vehicle is located.
• Lane Change Assist (LCA): recognizes other high-speed approaching vehicles in the LCA zone and displays the BSD warning light on the side mirror for the driver. The warning light flashes when the driver turns on the turn signal without recognizing a suddenly approaching vehicle from that direction.
• Rear Cross-Traffic Collision Warning (RCTA): generates a warning signal for vehicles approaching from the rear and sides while the vehicle is reversing.

1. 1
   When the engine is started with the switch in the OFF position, the OFF mode is activated.
2. 2
   When the ON switch is pressed in OFF mode, the passive mode is activated.
3. 3
   If the engine is started with the switch on, the passive mode is activated. ? When the ignition is on, the switch is in its initial state: the last position is retained.

   A.	If IGN OFF > ON with the switch on, the switch is on.

   B.	If IGN OFF > ON with the switch off, the switch is off.

4. 4
   If the engine is started with the BSD switch on, or if BSD is turned on when BSD is off, the outside rearview mirror warning light flashes for 2-3 seconds. This informs the driver that the BSD system is ready. (If the system is in Fail mode, there is no flashing.)
5. 5
   If the activation conditions (speed and radius of curvature) are met during driving, the active mode is activated (warning is issued).
6. 6
   If the activation conditions (speed and radius of curvature) are not met during driving, the passive mode is activated (warning is canceled).
7. 7
   If the BSD and LCA operation fails in any mode, Fail mode is activated.
8. 8
   If the BSD and LCA operations work normally in Fail mode, OFF mode is activated.
9. 9
   When the OFF switch is pressed while the BSD and LCA functions are operating (active/passive), OFF mode is activated.

    Warning Zone

    

11. 11
    BSD Warning Activation ConditionsThe entire body of the target vehicle is behind line A.Any part of the target vehicle crosses line B.Any part of the target vehicle crosses line D and hysteresis In.The entire part of the target vehicle passes line D and hysteresis In.

    

12. 12
    BSD Warning Deactivation ConditionsThe entire body of the target vehicle moves ahead of line A.The entire body of the target vehicle moves behind line B.The entire body of the target vehicle passes line D and hysteresis Out.The entire part of the target vehicle passes line E and hysteresis Out.

    

13. 13
    LCA Warning Activation ConditionsThe entire body of the target vehicle is behind line B.Any part of the target vehicle crosses line C.Any part of the target vehicle crosses line D and hysteresis In.The entire part of the target vehicle passes line E and hysteresis In.Under all of the above conditions, TTC (time to collision) is 4.5 s or more.

    

14. 14
    LCA Warning Deactivation ConditionsThe entire body of the target vehicle is in front of line B.The entire body of the target vehicle crosses line C.The entire body of the target vehicle passes line D and hysteresis Out.The entire body of the target vehicle passes line E and hysteresis Out.Under all of the above conditions, TTC (time to collision) does not exceed 4.5 s.

    

15. 15
    Sensor Activation ConditionsBSD and LCA switch (indicated by the switch LED) is ON.Vehicle speed: 30 km/h or higherRadius of curvature: 125 m or moreRelative vehicle speed: -10 to 250 km/h ("-" means the vehicle ahead is being overtaken)
16. 16
    Sensor Deactivation ConditionsBSD and LCA switch (indicated by the switch LED) is OFF.Vehicle speed: 28 km/h or lowerRadius of curvature: 125 m or lessRelative vehicle speed: All except -10 ~ 250 km/h ("-" means the vehicle ahead is being overtaken)
17. 17
    System Control ProhibitionRadar blocked by debris: System status - Blockage message is displayed.

    If the sensor on the rear bumper is covered with snow, dirt, or stickers, its detection performance may be reduced.

    Radar installation damaged by external impact: Output the DTC.BSD and LCA system malfunction: Output the DTC.Radar overheated: System status - Overheating message is displayed.

    Rear Cross Traffic Alert (RCTA)

    Item	Specification	Notes
    Vehicle Speed	0 to -10 km/h	R position
    Time to collision	4 ~ 36 km/h	+: closing
    Operating Zone	0.5 to 20 m	Vehicle: 20 m Bicycle: 15 m

    
    This function helps to detect vehicles approaching from the rear and sides when reversing out of a parking space in a busy parking lot.The warning is issued for a vehicle within 2 seconds based on time to collision (TTC), and a person is excluded from warning (warning may not be issued).

    Time to collision (TTC): The warning is issued when the calculated time to collision is 2 to 3.5 seconds, calculated from relative distance / relative speed. (Varies depending on relative approach speed.)
