On-vehicle apparatus, and method and computer program for transmitting positional information

An on-vehicle apparatus comprising:

• a storage device including a plurality of storage areas;
• a positional information generating section for generating, at every one of a first prescribed timing, a positional information piece representing a position of the vehicle which occurs at said every one of the first prescribed timing, and for writing the generated positional information piece into one of the storage areas, wherein the positional information generating section includes a GPS receiver;
• a positional information controlling section for sending positional information pieces in the storage areas to a positional information collecting apparatus at every one of a second prescribed timing, and for allowing new positional information pieces to be written into the storage areas in which the sent positional information pieces are stored;
• and
• wherein in cases where the positional information controlling section is not sending the positional information pieces in the storage areas to the positional information collecting apparatus, the positional information controlling section allows a new positional information piece or pieces to be written into one or more of the storage areas which store a positional information piece or pieces having not been sent yet;
• wherein the storage device stores information representing a map;
• a detour deciding section for deciding whether or not a detour is present in a route portion between positions represented by two among the positional information pieces having not been sent yet on the basis of the map;
• wherein in cases where the detour deciding section decides that a detour is present in the route portion, the positional information controlling section inhibits a new positional information piece from being written into the storage area storing a positional information piece generated between the moments of generation of said two among the positional information pieces.

• a route search section for searching a desired route to a destination which should be taken by the vehicle;
• a deviation information generating section for deciding whether or not the vehicle deviates from the desired route at every one of the first prescribed timing to generate a deviation information piece representing a result of said deciding, and for storing the generated deviation information piece into the storage device in a manner such that the generated deviation information piece and a positional information piece generated at the same one of the first prescribed timing are in correspondence;
• and
• a deviation deciding section for referring to the generated deviation information pieces and thereby detecting, among the positional information pieces having not been sent yet, a positional information piece or pieces generated during a term in which the vehicle deviates from the desire route;
• wherein the positional information controlling section inhibits a new positional information piece or pieces from being written into the storage area or areas storing the positional information or pieces detected by the deviation deciding section.
