The current position is calculated by detecting the travel distance
from the previous calculation point, and its direction change.
Travel distance The travel distance is generat ed from the vehicle speed sensor
input signal. The automatic distance correction function is adopted
for preventing a miss-detection of the travel distance because of
tire wear etc.
Travel direction The gyroscope (angular veloci ty sensor) and GPS antenna (GPS
information) generate the change of t he travel direction. Both have
advantages and disadvantages as per the following descriptions.
Input signals are prioritized in each situation. However, this order of priority may change in accordance with
more detailed travel conditions so that the tr avel direction is detected more accurately.
Map-matching
Map-matching repositions the vehicle on the road map when a new
location is judged to be more accurate. This is done by comparing
the current vehicle position (calculated by the normal position detec-
tion method) from the map data stored in the HDD (Hard Disk Drive).
There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is
driven over a certain distance or time in which GPS in formation is hard to receive. Correct manually the cur-
rent location mark on the screen.
In map-matching, several alternative routes are prepared and pri- oritized in addition to the road judged as currently driving on.
Therefore, due to errors in the distance and/or direction, an incor-
rect road may be prioritized, and the current location mark may be
repositioned to the incorrect road.
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, etc.

Type Advantage Disadvantage
Gyroscope (angular velocity
sensor) The turning angle is precisely detected.
Errors are accumulated when driving a long dis-
tance without stopping.
GPS antenna (GPS informa-
tion) The travel direction (North/South/East/West) is
detected. The travel direction is not precisely detected when
driving slowly.
