Output Signal Item

Reception unit Signal name Description
Combination meter CAN communication Meter display signal Nissan Murano Vehicle ahead detection indicator signal Transmits a signal to display a state of the system on the combination meter.
I-FCW/AEB system indicator signal Transmits a signal to turn ON the I-FCW/AEB system indicator.
Buzzer output signal Transmits a buzzer output signal to activate the buzzer.
Distance sensor (ICC sensor) ITS communication Nissan Murano Vehicle speed signal Transmits a vehicle speed calculated by the ADAS control unit.

DESCRIPTION

  • The I-FCW system will function when own vehicle is driven at speeds of approximately 3 MPH (5 km/h) and above.

  • The Intelligent Forward Collision Warning (I-FCW) System alerts the driver, by the Nissan Murano vehicle ahead detection indicator and chime, when the distance between own vehicle and a vehicle in front of the Nissan Murano vehicle ahead becomes closer.

NOTE:

The I-FCW/AEB system shares the diagnosis function with ICC system.

FUNCTION DESCRIPTION

The distance from the vehicle in front of the vehicle ahead and a relative speed are calculated by using the distance sensor (ICC sensor) and an distance sensor (ICC sensor) signal is transmitted to the ADAS control unit via ITS communication. When judging the necessity of warning according to the received distance sensor (ICC sensor) signal, the ADAS control unit transmits a warning buzzer signal and meter display signal to the combination meter via CAN communication.

I-FCW Operating Condition

  • I-FCW/AEB system display (white):ON

  • Vehicle speed: Approximately 3 MPH (5 km/h) and above.

  • Nissan Murano Vehicle in front of the vehicle ahead: Detected.

NOTE:

ON/OFF of I-FCW/AEB system is performed with the integral switch of the combination meter information display.
