Component Description
ADAS control unit
  • Being connected with side radar (LH and RH) via ITS communication, receives vehicle detection signal and transmits BSW/BSI indicator signal and BSW/BSI indicator dimmer signal to side radar
  • Being connected with lane camera unit via ITS communication, receives detected lane condition signal
  • Receives steering angle sensor signal from steering angle sensor via CAN communication
  • Judges a BSW/BSI indicator ON/OFF state and an approach state to the lane marker, based on each signal and calculates yaw moment to help return the vehicle back to the center of the lane.
  • Transmits target yaw moment signal to ABS actuator and electric unit (control unit)
  • Activates the warning buzzer and warning systems ON indicator
  • Transmits BSI ON indicator signal and BSW/BSI warning lamp signal to combination meter via CAN communication
Side radar LH/RH
  • Being connected with ADAS control unit via ITS communication, transmits vehicle detection signal
  • Receives BSW/BSI indicator signal and BSW/BSI indicator dimmer signal from ADAS control unit and transmits an indicator operation signal to BSW/BSI indicator LH/RH
  • RH side radar equips right/left switching signal circuit for identifying LH or RH because the parts of side radar are common for right and left
BSW/BSI indicator LH/RH Receives BSW/BSI indicator operation signal from side radar LH/RH and turns OFF, turns ON or blinks
Lane camera unit
  • Detects the lane marker by the built-in camera
  • Transmits detected lane condition signal to ADAS control unit
ABS actuator and electric unit (control unit)
  • Transmits vehicle speed signal to ADAS control unit via CAN communication
  • Transmits yaw rate signal/side G sensor signal to ADAS control unit via CAN communication
  • Receives a target yaw moment signal from the ADAS control unit via CAN communication and controls brake pressure of four wheels, respectively
Warning systems switch Inputs the switch signal to ADAS control unit
Dynamic driver assistance switch Inputs the switch signal to ECM
Warning systems ON indicator (On the warning systems switch) Indicates BSW system status
Warning buzzer Receives buzzer signal from ADAS control unit and sounds buzzer.
Combination meter
  • Turns the BSW/BSI warning lamp and BSI ON indicator ON/OFF according to the signals from the ADAS control unit via CAN communication
  • Receives BSI ON indicator signal, and BSW/BSI warning lamp signal via CAN communication.
Steering angle sensor Transmits steering angle sensor signal to ADAS control unit via CAN communication
BCM
  • Transmits turn indicator signal to ADAS control unit via CAN communication
  • Transmits dimmer signal to ADAS control unit via CAN communication
ECM Transmits the accelerator pedal position signal, engine speed signal and ICC steering switch signal (dynamic driver assistance switch signal) to ADAS control unit via CAN communication
TCM Transmits the output shaft speed signal, input speed signal, current gear position signal and shift position signal to ADAS control unit via CAN communication
A/C auto amp. Transmits the mode selection state of the drive mode select switch to ADAS control unit via CAN communication
AV control unit Transmits the system selection signal to ADAS control unit via CAN communication
