Component Description
Lane camera unit
  • Detects the lane marker by the built-in camera.
  • Judges the lane departure depending on the lane detection result and each signal.
  • Transmits the detected lane conditions to ABS actuator and electric unit (control unit) via CAN communication.
  • Controls the lane departure warning buzzer, lane departure warning lamp, warning systems ON indicator and LDP ON indicator lamp.
ABS actuator and electric unit (control unit)
  • Transmits vehicle speed signal to lane camera unit via CAN communication.
  • Judges necessary yaw moment depending on each signal.
  • Controls the brake pressure of each wheel individually to generate the intended movement.
Lane departure warning buzzer Gives a warning according to the direction from lane camera unit.
Dynamic driver assistance switch
(On the ICC steering switch)
Inputs the switch signal to ECM.
Combination meter Turns the lane departure warning lamp and LDP ON indicator lamp ON/OFF according to the signals from the lane camera unit via CAN communication (through unified meter and A/C amp.).
LDP ON indicator lamp (Green) Indicates LDP system status.
Lane departure warning lamp (Yellow)
  • Blinks when LDP is functioning to alert the driver.
  • Stays ON when LDW/LDP system is malfunctioning.
BCM
  • Transmits turn indicator signal to lane camera unit via CAN communication.
  • Transmits vehicle conditions to ABS actuator and electric unit (control unit) via CAN communication.
ECM Transmits vehicle conditions and ICC steering switch signal (dynamic driver assistance switch signal) to ICC sensor integrated unit via CAN communication.
Unified meter and A/C amp. Transmits ambient temperature signal to lane camera unit via CAN communication.
Steering angle sensor Transmits steering angle sensor signal to ABS actuator and electric unit (control unit) via CAN communication.
TCM Transmits vehicle conditions to ABS actuator and electric unit (control unit) via CAN communication.
ICC sensor integrated unit
  • Transmits ICC system conditions to ABS actuator and electric unit (control unit) via CAN communication.
  • Transmits LDP ON signal to ABS actuator and electric unit (control unit) via CAN communication.
Yaw rate/side G sensor Inputs detected yaw rate signal to ABS actuator and electric unit (control unit).
AV control unit Transmits system selection signal to ICC sensor integrated unit via CAN communication.
