MAP-MATCHING
Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This
is done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored
in the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the
vehicle is driven over a certain distance or time in which GPS
information is hard to receive. In this case, the current location
mark on the display must be corrected manually.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
+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, the alternative
routes will be shown in different order of priority, and the wrong
road can be avoided.
If two roads are running in parallel, they are of the same prior-
ity. Therefore, the current location mark may appear on either
of them alternately, depending on maneuvering of the steering
wheel and con®guration of the road.
+ Map-matching does not function correctly when the road on
which the vehicle is driving is new and not recorded in the map
DVD-ROM, or when the 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 ®nd another road and position the current
location mark on it. Then, when the correct road is detected, the
current location mark may leap 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 the current vehicle position
and the position on the map, correction by map-matching is not
possible.

EL-4163

Cause (condition) Driving condition Remarks (correction, etc.)
Place In a parking lot
SEL709V
When driving in a parking lot, or
other location where there are no
roads on the map, matching may
place the vehicle mark on a nearby
road. When the vehicle returns to the
road, the vehicle mark may have
deviated from the correct location.
When driving in circle or turning the
steering wheel repeatedly, direction
errors accumulate, and the vehicle
mark may deviate from the correct
location.
If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location cor-
rection and, if necessary, direction
correction.
Turn table
SEL710V
When the ignition switch is OFF, the
navigation system cannot get the
signal from the gyroscope (angular
speed sensor). Therefore, the dis-
played direction may be wrong and
the correct road may not be easily
returned to after rotating the vehicle
on a turntable with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other
roads where tires may slip easily,
accumulated mileage errors may
cause the vehicle mark to deviate
from the correct road.
Slopes When parking in sloped garages,
when travelling on banked roads, or
in other cases where the vehicle
turns when tilted, an error in the turn-
ing angle will occur, and the vehicle
mark may deviate from the road.
Map data Road not displayed on the map
screen
SEL699V
When driving on new roads or other
roads not displayed on the map
screen, map matching does not func-
tion correctly and matches the loca-
tion to a nearby road. When the
vehicle returns to a road which is on
the map, the vehicle mark may devi-
ate from the correct road.
Different road pattern (Changed due
to repair)
ELK0201D
If the road pattern stored in the map
data and the actual road pattern are
different, map matching does not
function correctly and matches the
location to a nearby road. The
vehicle mark may deviate from the
correct road.
Vehicle Use of tire chains When tire chains are used, the mile-
age is not correctly detected, and the
vehicle mark may deviate from the
correct road.Drive the vehicle for a while. If the
distance is still deviated, adjust it by
using the distance adjustment func-
tion. (If the tire chain is removed,
recover the original value.)

THE CURRENT LOCATION MARK IS IN A RIVER OR THE SEA
The navigation system moves the current location mark with no distinction between land and rivers or sea. If
the location mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea.
WHEN DRIVING ON THE SAME ROAD, SOMETIMES THE CURRENT LOCATION MARK IS IN
THE RIGHT PLACE AND SOMETIMES IT IS THE WRONG PLACE
The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually.
Depending on the road traveled and the operation of the steering wheel, the location detection results will be
different. Therefore, even on a road on which the location has never been wrong, conditions may cause the
vehicle mark to deviate.
LOCATION CORRECTION BY MAP MATCHING IS SLOW
+The map matching function needs to refer to the data of the surrounding area. It is necessary to drive some
distance for the function to work.
+ Because map matching operates on this principle, when there are many roads running in similar direc-
tions in the surrounding area, no matching determination may be made. The location may not be corrected
until some special feature is found.
ALTHOUGH THE GPS RECEIVING DISPLAY IS GREEN, THE VEHICLE MARK DOES NOT
RETURN TO THE CORRECT LOCATION
+The GPS accuracy has an error of about 10 m (30 ft). In some cases the current location mark may not
be on the correct street, even when GPS location correction is done.
+ The navigation system compares the results of GPS location detection with the results from map-match-
ing location detection. The one which is determined to have higher accuracy is used.
+ GPS location correction may not be performed when the vehicle is stopped.
THE NAME OF THE CURRENT PLACE IS NOT DISPLAYED
The current place name may not be displayed if there are no place names displayed on the map screen.
CONTENTS OF THE DISPLAY DIFFER FOR THE BIRDVIEW TAND THE (FLAT) MAP SCREEN
Difference of the BIRDVIEW Tscreen from the ¯at map screen are as follows.
+ The current place name displays names which are primarily in the direction of vehicle travel.
+ The amount of time before the vehicle travel or turn angle is updated on the screen is longer than for the
(¯at) map display.
+ The conditions for display of place names, roads, and other data are different for nearby areas and for
more distant areas.
+ Some thinning of the character data is done to prevent the display becoming to complex. In some cases
and in some locations, the display contents may differ.
+ The same place name, street name, etc. may be displayed multiple times.
