1. An information provision system for providing an occupant of the vehicle with information,comprising:

  • an information center including at least an information center controller, an information center data storage, and an information center wireless communication mechanism; and

    an in-vehicle apparatus including at least an in-vehicle apparatus controller, an in-vehicle apparatus data storage, and an in-vehicle wireless communication mechanism, an in-vehicle apparatus wireless communication mechanism, a vehicle position detector, and an output mechanism,the in-vehicle apparatus and the information center operable to communicate with each other by a wireless communication between the in-vehicle wireless apparatus communication mechanism and the information center wireless communication mechanism, wherein;

    the information center data storage stores a communication position information item to indicate a plurality of communication positions at which the in-vehicle apparatus is allowed to execute the wireless communication between the in-vehicle apparatus and the information center;

    the information center data storage stores, with respect to each of the plurality of communication positions, (i) a communication position information item for indicating the each of the communication positions, (ii) a notification position information item for indicating a notification position, and (iii) a notification information item which is notified to the occupant of the vehicle at the notification position, in association with each other;

    the information center controller causes the information center wireless mechanism to distribute to the in-vehicle apparatus, by the wireless communication, the communication position information item, which indicates the plurality of communication positions;

    the information center wireless communication mechanism acquires a reached communication position information item indicating a reached communication position, which is a communication position, from among the plurality of communication positions, that is reached by the vehicle, from the in-vehicle apparatus wireless mechanism using the wireless communication;

    the information center controller, with respect to the acquired reached communication position information item, causes the information center wireless mechanism to distribute a notification position information item and a notification information item from among the notification position information items and the notification information items stored in the information center data storage, to the in-vehicle apparatus using the wireless communication;

    the vehicle position detector acquires a vehicle position information item indicating a present position of the vehicle;

    the in-vehicle apparatus wireless communication mechanism acquires the communication position information item, which is distributed by the information center wireless mechanism using the wireless communication;

    the in-vehicle apparatus controller determines whether the vehicle reaches a communication position, based on (i) the communication positions indicated by the acquired communication position information item, and (ii) a present position of the vehicle indicated by the acquired vehicle position information item;

    the in-vehicle apparatus controller causes the in-vehicle apparatus wireless mechanism to transmit the reached communication position information item indicating the reached communication, when the in-vehicle apparatus controller determines that the vehicle reaches the one of the several communication positions, to the information center using the wireless communication;

    the in-vehicle apparatus wireless communication mechanism acquires the notification position information item and the notification information item, both of which are distributed by the information center wireless communication mechanism using the wireless communication;

    the in-vehicle apparatus controller determines whether the vehicle reaches the notification position, based on (i) the notification position indicated by the acquired notification position information item (ii) the present position of the vehicle indicated by the acquired vehicle position information item; and

    the in-vehicle apparatus controller causes the output mechanism to notify the occupant of the vehicle of contents indicated by the acquired notification information item when the in-vehicle apparatus controller determines that the vehicle reaches the notification position.
