BSI System Operation Description

• ADAS control unit enables BSI system.
• Turn ON the dynamic driver assistance switch, and BSI system setting on the navigation screen. Then BSI ON indicator comes on.
• Combination meter turns BSI ON indicator lamp ON/OFF according to the signals from ADAS control unit via CAN communication.
• Side radar detects a vehicle in the adjacent lane, and transmits the vehicle detection signal to ADAS control unit via ITS communication.
• Side radar receives vehicle speed signal from ADAS control unit and changes its detecting function.
• Lane camera unit monitors lane markers of the traveling lane and transmits the detected lane condition signal to ADAS control unit via ITS communication.
• ADAS control unit starts the control as follows, based on a vehicle detection signal, lane condition signal, turn signal and dimmer signal transmitted from BCM via CAN communication:
  • BSW/BSI indicator signal and BSW/BSI indicator dimmer signal transmission to side radar.
  • Buzzer signal transmission to warning buzzer.
  • 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/BSI indicator according to BSW/BSI indicator operation signal and BSW/BSI 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 of BSI System

ADAS control unit performs the control when the following conditions are satisfied.

• BSI ON indicator: ON
• When the vehicle drives at 60 km/h (37 MPH) or more to the forward direction.
  NOTE:

  • When the BSI system setting on the navigation screen is ON.
  • The BSI system may not function properly, depending on the situation. Refer to "PRECAUTIONS FOR BLIND SPOT WARNING/BLIND SPOT INTERVENTION ".
  • BSI 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 ICC, DCA, FCW or IBA warnings sound.
  • When the hazard warning flashers are operated.
  • When driving on a curve at a high speed.
• Under the following conditions, the BSI system will be turned off automatically, a beep will sound and the BSI ON indicator will blink. The BSW system is still available, but the BSI system will not be available until the conditions no longer exist.
  • When the VDC system (except TCS function) or ABS operates.
  • When the VDC system is turned OFF.
  • When the drive mode select switch is turned to the SNOW mode.
