Positional information use apparatus
First Claim
1. A positional information use apparatus for a vehicle, the apparatus comprising:
- a position calculation unit configured to calculate a current position of the vehicle;
a POI storing unit configured to store POI positional information on a position of a Point Of Interest (POI);
an acquisition unit configured to acquire state information on a change in a heading direction of the vehicle;
an area determination unit configured to make an area determination, based on the calculated current position, as to whether the vehicle is present within a predetermined stop-off determination area, which is defined based on the stored POI positional information, for determining a stop-off of the vehicle at the POI; and
a stop-off determination unit configured to make a stop-off determination, based on the acquired state information, as to whether the vehicle stops off at the POI when the area determination is affirmatively made.

Abstract
A vehicular swept path processor and a map matching processor calculate a current position of a subject vehicle. A gyro sensor and a steering sensor output detection signals. A POI recognition processor makes a determination as to whether the vehicle stopped off at a POI or not based on the calculated current position and the outputted detection signals. When the determination is affirmatively made, i.e., the vehicle is determined to have stopped off at the POI, the POI recognition processor calculates a recognition confidence degree relative to an accuracy in the determination. A vehicle control ECU controls an in-vehicle device such that the in-vehicle device performs a predetermined operation corresponding to the POI in a mode according to the calculated recognition confidence degree.

7. A method for determining a stop-off at a spot by a vehicle, comprising the steps of:
-
storing spot positional information on a position of a spot; calculating a current position of the vehicle; acquiring state information on a change in a heading direction of the vehicle; making an area determination, based on the calculated current position, as to whether the vehicle is present within a predetermined stop-off determination area, which is defined based on the stored spot positional information, for determining a stop-off of the vehicle at the spot; and making a stop-off determination, based on the acquired state information, as to whether the vehicle stops off at the spot when the area determination is affirmatively made.
