FUNCTION DESCRIPTION
- Lane Departure Warning (LDW) system provides a LDW function when the vehicle is driven at speeds of approximately 60 km/h (37 MPH) or more.
- When the vehicle approaches either the left or the right side of the traveling lane, a steering vibration activates and the LDW indicator (yellow) on the combination meter blinks to alert the driver.
- The warning does not occur during turn signal operation (Lane change side).
- The warning function stops when the vehicle returns inside of the lane markers.
EXAMPLE
When the vehicle approaches the right lane marker, the driver is alerted by the steering vibration and the blinking of LDW warning display (yellow).
OPERATION DESCRIPTION
- The front camera unit monitors lane markers of the traveling lane.
- When judging from a lane marker detection signal that the vehicle is approaching the lane marker, the ADAS control unit 2 controls the following item to alert the driver.
- Activates the steering vibration motor by ADAS control unit 2.
- ADAS control unit 2 transmits a meter display signal to combination meter via CAN communication and turns ON/OFF the LDW system display.
OPERATION CONDITION
ADAS control unit 2 performs the control when the following conditions are satisfied.
- LDW system: ON
- Vehicle speed: approximately 60 km/h (37 MPH) or more
- Turn indicator signal: After 2 seconds or more from turned OFF
NOTE:
- LDW system ON/OFF can be set on the information display.
- After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches approximately 55 km/h (34 MPH)
- The LDW system may not function properly, depending on the situation. Refer to Handling Precaution .
CANCEL CONDITION
The ADAS control unit 2 cancels the operation when the system is under any conditions of the operation cancellation condition.
- When the system malfunction occurs.
- When the front camera unit becomes high temperature [over approximately 40 °C (104 °F)].
