LANE DEPARTURE PREVENTION (LDP) SYSTEM : Component Description

WARNING: This page is about a different car, the 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
COMPONENT DESCRIPTION

Component Description
ADAS control unit
  • Judges lane departure based on each signal and calculates yaw moment necessary to generate force toward the direction to recover the vehicle from the lane departure
  • Outputs the warning buzzer signal to the warning buzzer
  • Transmits a target yaw moment signal to the ABS actuator and electric unit (control unit) via CAN communication
  • Transmits the lane departure warning lamp signal and LDP ON indicator lamp signal to combination meter via CAN communication
Lane camera unit
  • Detects the lane marker in travel lane
  • Transmits the detected lane condition signal to ADAS control unit via ITS communication
ABS actuator and electric unit (control unit)
  • Transmits the vehicle speed signal (wheel speed) to ADAS control unit via CAN communication
  • Transmits the yaw rate signal and 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 buzzer Activates the warning buzzer, according to a warning buzzer signal received from the ADAS control unit
Dynamic driver assistance switch (On the ICC steering switch) ECM receives an ICC steering switch (dynamic driver assistance switch) signal and transmits the signal to ADAS control unit via CAN communication
Combination meter Turns on the following indicator/warning lamp, according to a signal received for the ADAS control unit via CAN communication
  • LDP ON indicator lamp (Green)
  • Lane departure warning lamp (Yellow)
BCM Transmits the turn indicator 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
Steering angle sensor Transmits the steering angle sensor signal to ADAS control unit via CAN communication
TCM Transmits the output shaft revolution signal, input speed signal, current gear position signal and shift position signal to ADAS control unit via CAN communication
Transfer control unit Transmits the current 4WD mode signal to ADAS control unit via CAN communication
AV control unit Transmits the system selection signal to ADAS control unit via CAN communication
