Hyundai Genesis: Blind Spot Detection system / Description and Operation

Description

-	Blind Spot Detection (BSD) : Senses other vehicles in the BSD zone and turns on the BSD warning lamp for the driver. Warning lamp starts blinking when the driver turns on the turn signal lamp to enter the lane where another vehicle is driving

-	Lane Change Assist (LCA) : Senses other vehicles approaching at high speed in the BSD zone and turns on the BSD warning lamp for the driver. Warning lamp starts blinking when the driver turns on the turn signal lamp without recognizing any sudden approaching vehicle from that direction.

-	Rear Cross Traffic Alert (RCTA) : When the vehicle is on the reverse, the RCTA generates alarm to alert another vehicle approaching from the rear and side.

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. 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.	If you start the engine with BSD switch ON, orif you turn on the BSD with IGN OFF, the warning lamp of the door mirror keeps blinking 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 blinking)

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.

1.	Warning zone

2.	Conditions for BSD warning ON The entire body of the target vehicle is located behind the line A. Some part of the target vehicle passes the line B. Some 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.

3.

Conditions for BSD warning OFF The entire body of the target vehicle moves behind the line B. The entire body of the target vehicle moves before the line A. 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 before 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 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: -15 ~ 255?/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: 125m or less Relative car speed: All except -15 ~ 255?/h ("-" means overtaking the preceding vehicle)

8.

System control prohibition The radar is covered with debris : System conditions - Blockage message is outputted If snow, mud or stickers interfere with the sensor on the rear bumper, its detecting performance may deteriorate. The radar installation is damaged by an outside shock : the error code is sent BSD & LCA system fails : the error code is sent The radar is overheated: System conditions - Over Temperature message is outputted.

9.

Rear Cross Traffic Alert (RCTA) Item Specification Remarks Vehicle speed 0 ~ -10 kph R' position Time To Collision 4 ~ 36 kph  + : closing  Operating area 0.5 ~ 20 m Vehicle : 20m Bike : 15m It is a function to help the driver check other vehicles approaching from the rear or side when the driver reverses the vehicle which was parked front-in. The alarming is made for the vehicle within 2 seconds based on the Time To Collision (TTC) and a person is excluded for alarming (The alarming may not be made.) Time To Collision (TTC) : It means to issue an alarm in case that the estimated time before collision is 2 to 3.5 sec based on the calculation of the relative distance/relative speed (subject to change depending on the relative speed of the approaching vehicle). The warning zone is as follows.
