COMPONENT PARTS
LANE DEPARTURE PREVENTION (LDP) SYSTEM : Component Description
INFOID:0000000006223703
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 combina-
tion 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 communi-
cation
• 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
