FUNCTION DESCRIPTION
  • The Active Blind Spot Assist [ABSA] can help alert the driver of other vehicles in adjacent lanes when changing lanes. Active Blind Spot Assist [ABSA] always operates together with Blind Spot Warning.
  • The Active Blind Spot Assist [ABSA] operates above approximately 60 km/h (37 MPH).
  • The Active Blind Spot Assist [ABSA] uses side radar installed near the rear bumper to detect other vehicles beside vehicle in an adjacent lane.
  • The side radar can detect vehicles on either side of vehicle within the detection zone shown as illustrated.
  • This detection zone starts from the outside mirror of vehicle and extends approximately 10 ft (3.0 m) behind the rear bumper, and approximately 10 ft (3.0 m) sideways.
  • If the BSW indicator is illuminated while vehicle is approaching a lane marker, the BSW indicator blinks and an audible warning will sound three times. Then the system applies the brakes on one side of the vehicle for a short period of time to help return the vehicle back to the center of the lane.
  • Active Blind Spot Assist [ABSA] operates regardless of turn signal usage.
  • The brightness of BSW indicator lights is adjusted automatically depending on the brightness of the ambient light.
note
  • Active Blind Spot Assist [ABSA] is typically activated earlier than LDP when getting closer to the lane marker.
  • Warning and brake control will only be activated if the BSW indicator is already illuminated when vehicle approaches a lane marker.
  • If another vehicle comes into the detection zone after vehicle has crossed a lane marker, no warning or brake control will be activated.
 
 
OPERATION DESCRIPTION
  • ADAS control unit 2 enables Active Blind Spot Assist [ABSA].
  • Turn ON the dynamic driver assistance switch, and Active Blind Spot Assist [ABSA] setting on the information display.
  • Combination meter turns Active Blind Spot Assist [ABSA] display ON/OFF according to the signals from ADAS control unit 2 via CAN communication.
  • Side radar detects a vehicle in the adjacent lane, and transmits the vehicle detection signal to ADAS control unit 2 via CAN communication.
  • Side radar receives vehicle speed signal from ADAS control unit 2 and changes its detecting function.
  • Front camera unit monitors lane markers of the traveling lane and transmits the detected lane condition signal to ADAS control unit 2 via CAN communication.
  • ADAS control unit 2 starts the control as follows, based on a vehicle detection signal, lane condition signal, turn signal and position light request signal transmitted from BCM via CAN communication:
    • BSW indicator signal and BSW indicator dimmer signal transmission to side radar.
    • Calculation of necessary yaw moment and transmission of the target yaw moment signal to ABS actuator and electric unit (control unit).
  • Side radar transmits an indicator operation signal to the BSW indicator according to BSW indicator operation signal and BSW indicator dimmer signal.
  • ABS actuator and electric unit (control unit) controls brake pressure of four wheels respectively according to the target yaw moment signal.
 
 
OPERATION CONDITION
  • Active Blind Spot Assist [ABSA]: ON
  • Vehicle speed: Approximately 60 km/h (37 MPH) or more
note
  • Active Blind Spot Assist [ABSA] ON/OFF can be set on the information display.
  • The Active Blind Spot Assist [ABSA] may not function properly, depending on the situation. Refer to Handling Precaution.
  • Active Blind Spot Assist [ABSA] braking will not operate or will stop operating and only a warning chime will sound under the following conditions.
    • When the brake pedal is depressed.
    • When the accelerator pedal is depressed while brake control assist is provided.
    • When steering quickly.
    • When the MI-PILOT Assist or AEB warnings sound.
    • When the hazard warning flashers are operated.
    • When driving on a curve at a high speed.
  • Under the following conditions, the Active Blind Spot Assist [ABSA] will be turned off automatically, a beep will sound and the Active Blind Spot Assist [ABSA] display will change color to yellow. The BSW system is still available, but the Active Blind Spot Assist [ABSA] will not be available until the conditions no longer exist.
    • When the ASC system (except TCS function) or ABS operates.
    • When the ASC system is turned OFF.
 
 
CANCEL CONDITION
The ADAS control unit 2 cancels the operation when the system is under any conditions of the operation cancellation condition.
  • When the system malfunction occurs.
  • When the front camera unit becomes high temperature [over approximately 40 °C (104 °F)].
  • When the area around the side radar is dirty.
  • When the ASC or ABS (Including the TCS) operates.
  • When the ASC is turned OFF
  • When the SNOW mode, GRAVEL mode or MUD mode is selected (AWD models).
