●

For Navigation System operation information, refer to Navigation System Owner's Manual.

●

Each control unit that comprises the system is connected with a communication circuit. It transmits/
receives data signals including request signals and response signals, and controls the system.

●

The display control unit transmits/receives data signals to/from each control unit with CAN communica-
tion. It performs an arithmetical operation on fuel information values by using data obtained from the con-
trol units, and then displays the calculated values on the screen.

●

The display control unit receives door switch signals from the BCM with CAN communication, and dis-
plays a warning on the screen when driving over the set speed with a door half-shut.

●

The display control unit receives vehicle speed signals that are transmitted from the unified meter and A/
C amp., performs an arithmetical operation on drive information values, and then displays the calculated
values on the screen.

●

The images displayed on the monitor screen contain NAVI control unit-generated RGB images, display
control unit-generated RGB images, and rear view images transmitted from the rear view camera control
unit.

NAVIGATION SYSTEM

Revision: 2006 August

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 DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-location mark. More accurate data is judged and used by comparing vehicle
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 selected because priorities are set for the signals from these two
devices according to the situation.

Type

Advantage

Disadvantage

Gyroscope (angular velocity sen-
sor)

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.

Map-Matching

Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from DVD-
ROM stored in DVD-ROM drive.

NOTE:
The road map data is based on data stored in the 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 are prepared and prioritized
in addition to the road judged currently driven. Due to the dis-
tance and/or direction error, the incorrect road may be prioritized
and current-location mark may be repositioned to the wrong
road.
When two roads are running in parallel, they are judged to 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 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 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.

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 21,000 km
(13,100 miles).
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), and utilize the altitude data cal-
culated 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 10 m (30ft).

●

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.

●

For easier recognition of the vehicle width and the distance to the objects, the guide lines of distances and
rear are combined with the rear view image.

●

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