NAVIGATION SYSTEM

System Description

AKS00D2B

NAVIGATION SYSTEM
Location Detection Principle

The navigation system periodically calculates the vehicle's current
position according to the following three signals:

●

Travel distance of the vehicle as determined by the vehicle
speed sensor

●

Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)

●

Direction of vehicle travel as determined by the GPS antenna
(GPS information)

The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen as a current-location mark. More accurate data is judged and used by comparing vehi-
cle position detection results found by the GPS with the result by map-matching.

The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.

●

Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.

●

Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.

More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.

SKIB1058E

SEL684V

Type

Advantage

Disadvantage

Gyroscope
(angular velocity sensor)

Can detect the vehicle's turning angle quite
accurately.

Direction errors may accumulate when vehicle is
driven for long distances without stopping.

GPS antenna
(GPS information)

Can detect the vehicle's travel direction
(North/South/East/West).

Correct direction cannot be detected when vehi-
cle speed is low.

NAVIGATION SYSTEM

AV-105

Revision: 2005 August

2005 Murano

Map-Matching

Map-matching compares a current location detected by the method
in the “Location Detection Principle“ (refer to

AV-104

) with a road

map data from Map DVD-ROM stored in DVD-ROM drive.

NOTE:
The road map data is based on data stored in the map DVD-ROM.

The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In this case, the current-location mark on the display must be
corrected manually.

●

In map-matching, alternative routes to reach the destination will
be shown and prioritized, after the road on which the vehicle is
currently driven has been judged and the current-location mark
has been repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in different order of priority, and the incorrect road
can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the current-location mark may appear on either of
them alternately, depending on maneuvering of the steering
wheel and configuration of the road.

●

Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the
actual road pattern are different due to repair.
When driving on a road not present in the map, the map-match-
ing function may find another road and position the current-loca-
tion mark on it. Then, when the correct road is detected, the
current-location mark may change to it.

●

Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between current vehicle position and
the position on the map, correction by map-matching is not possible.

NAVIGATION SYSTEM

Revision: 2005 August

GPS (Global Positioning System)

GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 13,100 miles
(21,000 km).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:

●

In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.

●

The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.

●

Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.

NOTE:

●

Even a high-precision three dimensional positioning, the detection result has an error about 30 ft (10 m).

●

Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

REAR VIEW MONITOR

●

A rear view monitor was set to vehicle, which can check rearward on screen when backing up the vehicle.

●

The sense of vehicle width and sense of distance between vehicle and objects were set to be easier to get
by combining guideline of distances and rear end to the rear view screen.

●

Image quality of the rear view image and of the navigation screen can be adjusted separately.

NAVI CONTROL UNIT

●

The gyro (angular speed sensor) and the DVD-ROM drive are
built-in units that control the navigation functions.

●

Signals are received from the gyro, the vehicle speed sensor,
and the GPS antenna. Vehicle location is determined by com-
bining this data with the data contained in the DVD-ROM map.
Locational information is shown on liquid crystal display panel.

DVD-ROM DRIVE

Maps, traffic control regulations, and other pertinent information can
be easily read from the DVD-ROM disc.

MAP DVD-ROM

●

The map DVD-ROM has maps, traffic control regulations, and other pertinent information.

●

To improve DVD-ROM map matching and route determination functions, the DVD-ROM uses an exclusive
Nissan format. Therefore, the use of a DVD-ROM provided by other manufacturers cannot be used.

GYRO (ANGULAR SPEED SENSOR)

●

The oscillator gyro sensor is used to detect changes in vehicle steering angle.

●

The gyro is built into the navigation (NAVI) control unit.
