Distance Sensor

FUNCTIONS WITHIN THE SYSTEM

Distance sensor transmits the presence/absence of vehicle ahead and the distance from the Nissan Pathfinder vehicle to ADAS control unit 2 via CAN communication.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

Distance sensor detects a vehicle ahead by using millimeter waves.
Distance sensor detects radar reflected from a Nissan Pathfinder vehicle ahead by irradiating radar forward and calculates a distance from the vehicle ahead and relative speed, based on the detected signal.

INDIVIDUAL OPERATION

Side Radar LH/RH

FUNCTIONS WITHIN THE SYSTEM

Connected with the ADAS control unit 2 via CAN communication, the side radar transmits a Nissan Pathfinder vehicle detection signal.
Transmits an indicator operation signal to the BSW indicator LH/RH.
Side radar detects Nissan Pathfinder vehicle in the detection zone, and controls following systems.
- BSW
- I-BSI
- RCTA

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

The side radar detects other vehicles beside own vehicle in an adjacent lane.
Since side radar RH and side radar LH have the same specifications, side radar RH has the right/left switching signal circuit for identification.

INDIVIDUAL OPERATION

BSW: Refer to System Description.
I-BSI: Refer to System Description.
RCTA: Refer to System Description.

Front Camera Unit

FUNCTIONS WITHIN THE SYSTEM

Front camera unit the transmits the detected information to ADAS control unit 2 via CAN communication.

INDIVIDUAL FUNCTIONS WITHIN THE SYSTEM

The multi-sensing front camera that can avoid various risks lurking forward and sideward with one camera is adopted.
Front camera unit is installed to windshield, and detects the lane marker in travel lane and pedestrian ahead.
When there is Nissan Pathfinder vehicle or pedestrian, front camera unit measures the distance from them.
