Operation Description
- LDP system is controlled by chassis control module and ADAS control unit.
- When the system is turned ON by dynamic driver assistance switch, ADAS control unit transmits LDP ON signal to chassis control module via chassis communication.
- Lane camera unit monitors lane markers of the traveling lane and transmits the detected lane condition signal to chassis control module via chassis communication.
- When judging from a lane marker detection signal that the vehicle is approaching the lane marker, chassis control module controls the following items.
- Transmits LDP system display signal and warning buzzer signal to ADAS control unit via chassis communication.
- Calculates necessary steering angle to transmit steering angle signal to steering angle main control module via chassis communication.
- ADAS control unit controls the following items according to the signals from chassis control module.
- Transmits warning buzzer signal to warning buzzer through driver assistance buzzer control module via ITS communication.
- Transmits LDP system display signal to combination meter via CAN communication.
- Direct Adaptive Steering* controls steering angle according to the steering angle signal.
*: Direct Adaptive Steering is controlled by three control modules of steering force control module, steering angle main control module and steering angle sub control module.
- Combination meter displays LDP system display on the information display.
OPERATING CONDITION
- LDP system display (green): ON (Dynamic driver assistance icon ON "Lane" position and dynamic driver assistance switch ON)
- Vehicle speed: approximately 70 km/h (45 MPH) or more
- Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
- LDP system ON/OFF can be set on the integral switch.
- After the operating conditions are satisfied, the control continues until the vehicle speed reaches approximately 60 km/h (37 MPH).
- LDP system may not function properly, depending on the situation. Refer to Precautions for Lane Departure Warning/Lane Departure Prevention .
