FUNCTION DESCRIPTION

• Intelligent Lane Intervention system provides a lane departure warning and brake control assistance when the Nissan Murano 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, the steering vibration motor activates, a warning sounds and the lane departure warning lamp (yellow) on the combination meter blinks to alert the driver. Then, the Intelligent Lane Intervention system automatically applies the brakes for a short period of time to help assist the driver to return the Nissan Murano vehicle to the center of the traveling lane.

• Warning and brake control are not performed during turn signal operation (lane change side).

• The warning and assist functions stop when the Nissan Murano vehicle returns to a position inside of the lane marker.

EXAMPLE

When the vehicle approaches the right lane marker, the driver is alerted by the steering vibration motor, the warning system buzzer and the blinking of lane departure warning lamp (yellow). Simultaneously, the left brake is controlled independently to generate force toward the direction to recover the Nissan Murano vehicle from the lane departure.

OPERATION DESCRIPTION

The system is turned ON by the lane intervention switch, ADAS control unit transmits Intelligent Lane Intervention ON indicator signal to combination meter via CAN communication.

• Lane camera unit monitors lane markers of the traveling lane. It transmits the detected lane condition signal to ADAS control unit via ITS communication.

• When judging from a lane marker detection signal that the Nissan Murano vehicle is approaching the lane marker, ADAS control unit controls the following items:

  • Activates the steering vibration motor by the ADAS control unit

  • Transmits a warning system buzzer signal to activate the warning system buzzer.

  • Transmits a lane departure warning lamp signal to combination meter via CAN communication.

  • Calculates necessary yaw moment to transmit a target yaw moment signal to ABS actuator and electric unit (control unit) via CAN communication.

• When receiving the target yaw moment signal, ABS actuator and electric unit (control unit) controls brake pressure of four wheels, respectively.

• When receiving the signal from ADAS control unit, combination meter turns ON/OFF the lane departure warning lamp (yellow) and the Intelligent Lane Intervention ON indicator lamp (green).

OPERATING CONDITION

• Intelligent Lane Intervention ON indicator lamp: ON

• Vehicle speed: approximately 60 km/h (37 MPH) or more

• Turn indicator signal: After 2 seconds or more from turned OFF

NOTE:

• When the Intelligent Lane Intervention system setting in the Nissan Murano vehicle information display is ON.

• After the operating conditions are satisfied, the control continues until the Nissan Murano vehicle speed reaches approximately 50 km/h (30 MPH).

• The Intelligent Lane Intervention system may not function properly, depending on the situation. Refer to Precaution for Intelligent Lane Intervention.
