SEL504X
System DescriptionNJEL0516OUTLINENJEL0516S01The Navigation System (Multi-AV System) relies upon three sens-
ing devices in order to determine vehicle location at regular time
intervals.
1. Vehicle speed sensor: Determines the distance the vehicle has
traveled.
2. Gyro (Angular velocity sensor): Determines vehicle steering
angle and directional change.
3. GPS antenna (GPS data): Determines vehicle forward move-
ment and direction.
The data provided by the three sensing functions together with a
comparison of the mapping information read from the CD-ROM
drive permit accurate determination of the vehicle's current location
and subsequent course (map matching). The information appears
on a liquid crystal display.
This comparison of GPS data (vehicle position sensing) and map
matching permits precise determination of vehicle location.
SEL684V
Position Sensor Operating PrinciplesNJEL0516S0101The sensor determines current vehicle location by calculating the
previously sensed position, the distance traveled from this position,
and the directional changes occurring during this travel.
1. Distance traveled
The distance traveled is calculated using signals received from
the vehicle speed sensor. The sensor automatically compen-
sates for the slightly reduced wheel and tire diameter resulting
from tire wear.
2. Forward movement (Direction)
Changes in the direction of forward movement are calculated
by the gyro (angular velocity sensor) and the GPS antenna
(GPS data). Each of these functions has its advantage and
disadvantages. Depending upon conditions, one function takes
precedence over the other to accurately determine the direc-
tion of forward movement.
Function type Advantage Disadvantage
Gyro (Angular
velocity sen-
sor)+Able to accurately detect
minute changes in steering
angle and direction.+Calculation errors may
accumulate over a long
period of continuous
vehicle travel.
GPS antenna
(GPS data)+Able to sense vehicle travel
in four general directions
(North, South, East, and
West)+Unable to detect direction
of vehicle travel at low
vehicle speeds.

System Description
EL-261
Possible cause Drive condition Service procedure
AreaSlippery road surfaceOn wet, icy, or gravel road where
frequent wheel slippage occurs, dis-
tance calculations may be errone-
ous. The position marker may show
the vehicle to be in inaccurate posi-
tion.
If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªAdjust Current Loca-
tionº MODE (EL-298). If
necessary, perform ªSpeed
Calibrationº (EL-290). Slanted areaHilly areas where the road has
banked curves. When the vehicle
enters these banked curves, there
may be an error in steering angle
measurement. The position marker
may show the vehicle to be in inac-
curate position.
Map
dataMap display for a given road does not appear.
SEL699V
When the vehicle is driven on a
newly constructed road that does
not appear on the existing map. Map
marking and calibration are not pos-
sible. The position marker may indi-
cate inaccurate position in close
proximity to the actual position.
Subsequently, when the vehicle is
driven on a road which is available
as map data, the position marker
may still indicate an inaccurate posi-
tion.
The vehicle is driven on a road whose course has
been altered (usually to improve the road or to
eliminate some hazard).
SEL700V
When the map data shown on the
display and the actual conditions are
different. Map matching will not be
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position. If the
vehicle is driven on the indicated
road, further errors may occur.
Vehicle Use of tire chains (Stormy weather)Tire chains will affect distance sens-
ing. The position marker may indi-
cate inaccurate position.If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªSpeed Calibrationº (EL-
290). After removing the tire
chains, sensing accuracy
may recover by itself.

This Condition Is Not Abnormal (Cont'd)
EL-311
Possible cause:
Ð: Vehicle running ---: IndicationDrive condition Service procedure
Loca-
tionParking lot or similar area
SEL709V
When the vehicle is driven in a park-
ing lot or similar area, such as in an
area not normally marked as a road
on map, during map matching, the
system may select nearby roads.
This error may continue after the
vehicle exits the parking area and
begins to run on ordinary roads.
Vehicle operation in a parking area
may involve frequent turns and up
and/or down operation. Directional
sensing errors may occur leading to
subsequent route and position mis-
takes.If the position marker does
not move to the correct posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªStore placeº. If
required, also perform
ªAdjust Current Locationº
MODE (EL-298). Turntable
SEL710V
When the ignition switch is OFF (the
usual situation when the vehicle is
on a turntable), the navigation sys-
tem receives no data from the gyro
(angular velocity sensor). When the
turntable rotates, no directional
change is sensed. During subse-
quent vehicle operation, directional
and route errors may occur.
Position marker displays a completely different location
In circumstances such as those described below, GPS signal reception conditions may result in an erroneous
position of the position marker. Perform ªAdjust Current Locationº MODE (EL-298).
NOTE:
+When GPS satellite signal reception conditions are poor, the position of position marker may be errone-
ous. If correction is not made immediately, the position marker error will be compounded and a completely
different location will be indicated. In an area where GPS satellite signal reception conditions are good,
the system can be returned to normal operation.
+The vehicle is driven aboard a car ferry or is towed for some distance with the ignition switch OFF. Vehicle
movement is not sensed. Current location calculations do not occur and current location data does not
appear on the display screen. Use GPS to accurately determine actual vehicle position. The system can
be returned to normal operation when the GPS satellite signal reception conditions are good.
Position marker jumps
In circumstances such as those described below, the position marker may jump as a result of automatic cur-
rent location corrections made by the system.
During map matching
+During map matching, the position marker may jump from one spot to another. In this case, it may be cor-
rected to a wrong road or to an area where no road exist.
GPS location correcting
+Vehicle current location is sensed using the GPS data. Positional calibration is performed. The position
marker continues to be in the wrong position. It may jump about from one area of the screen to another.
In this case, it may be corrected to a wrong road or to an area where no road exist.
Position marker indicates that the vehicle is in the middle of an ocean or large river
The navigation system does not distinguish between land and water surfaces. In some cases, a position
marker error may cause the display to show the vehicle above a water surface.
Position of position marker varies when the vehicle is repeatedly operated on the same road
Driving lane and steering wheel movement results in a variety of different positions of the position mark when
traveling on the same road based on sensing results by the GPS antenna and gyro (angular velocity sensor).
Slow locational correction using map matching
+The map matching function requires verification of local data. To make the map matching function, some
distance needs to be driven.
+The map matching function may not provide accurate performance in an area where there are numerous
parallel roads. Until the system judges the road characteristics, an incorrect position may be shown.
