< SYMPTOM DIAGNOSIS >
[BOSE AUDIO WITH NAVIGATION]
NORMAL OPERATING CONDITION
Cause (condition)
Driving condition
Remarks (correction, etc.)
Road
pattern
Y–intersections
At a Y intersection or similar gradual divi-
sion of roads, mistakes in the direction of
travel deduced by the sensor may result in
the vehicle mark appearing on the wrong
road.
If after traveling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction, and if neces-
sary, direction correction.
Spiral roads
When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.
Straight roads
When driving on a long, straight road and
gentle curve road without stopping, map-
matching does not work effectively enough
and distance errors may accumulate. As a
result, the vehicle mark may deviate from
the correct location when the vehicle turned
at a corner.
Switchback turn
When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.
Roads laid out in a grid pattern
When driving at where roads are laid out in
a grid pattern, where many roads are run-
ning in the similar direction nearby, the map
may be matched to them by mistake and
the vehicle mark may deviate from the cor-
rect location.
Parallel roads
When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate from
the correct location.
