Map Matching Remarks
•
The map matching function proposes route correction on an order of priority other than the currently indicated
route. Therefore, when the navigation unit detects travelling speed or progressive direction errors, it could
mistake the order of priority and fail to correct the route.
•
Due to the system operation principles, the map matching function may be unable to determine which route a
vehicle is taking when there are similar roads around the vehicle, and may not correct the vehicle's position
until it can find a particular route.
•
While driving on a road that does not exist in the map data or when the actual vehicle's position is far away from
the position indicated by the vehicle locator mark, map matching will not be performed.
•
Under the following driving conditions and GPS satellite conditions, the vehicle locator mark may deviate from
the actual position of the vehicle. This does not indicate any breakdown in the system and if driving continues
for a while, the current position will be corrected automatically.
Cause (Condition) Driving condition
•
At a Y-shaped fork in the road where the roads separate gradually, the vehicle
locator mark may be displayed on the wrong road.
•
If the vehicle makes continuous, large turns, for example on a loop structure,
the vehicle locator mark may go off the road altogether.
•
After driving for a long distance in a straight line or through gentle curves, if
the vehicle turns a corner, the vehicle locator mark may be displayed on the
wrong road.
•
On a zigzag road, the vehicle locator mark may go off the road.
