1. A center device comprising:
a behavior data acquisition unit configured to acquire behavior data indicating a behavior of a user;
a behavior data storage configured to store the behavior data acquired by the behavior data acquisition unit;
a vehicle state data acquisition unit configured to acquire vehicle state data indicating a state of a vehicle;
a vehicle state data storage configured to store the vehicle state data acquired by the vehicle state data acquisition unit;
a distribution plan creation unit configured to create a distribution plan of reprogramming data to be distributed to a plurality of vehicle devices of the vehicle by using the behavior data stored in the behavior data storage and the vehicle state data stored in the vehicle state data storage;
a distribution control unit configured to distribute the reprogramming data to the plurality of vehicle devices according to the distribution plan created by the distribution plan creation unit; and
a first wireless communication unit configured to wirelessly communicate with the vehicle using a first communication method within a first communication range;
a first communication state acquisition unit configured to acquire a first communication state between the vehicle and the first wireless communication unit;
a second wireless communication unit configured to wirelessly communicate with the vehicle using a second communication method within a second communication range which is smaller than the first communication range; and
a second communication state acquisition unit configured to acquire a second communication state between the vehicle and the second wireless communication unit;
wherein:
the behavior data acquisition unit acquires, as the behavior data, the first communication state acquired by the first communication state acquisition unit and the second communication state acquired by the second communication state acquisition unit; and
the behavior data acquisition unit acquires the behavior data indicating the behavior of the user based on the (i) the first communication state acquired by the first communication state acquisition unit, (ii) the second communication state acquired by the second communication state acquisition unit, and (iii) a second communication possible time at which the vehicle is estimated to enter the second communication range from a position outside of the second communication range by comparing a position of the vehicle, a traveling locus of the vehicle, or a destination of the vehicle with the second communication range specified based on the second communication state.
