PROBLEM TO BE SOLVED: To suppress delay in vehicle search.SOLUTION: In an on-vehicle device 12, a communication section 130 transmits vehicle information related to a vehicle to a server 14. A vehicle action prediction section 132 repetitively predicts the prediction route of the vehicle on the basis of the vehicle information until predetermined prediction time. When a search condition transmitted from the server 14 is received, an inference section 134 calculates a confidence factor on the basis of the predicted route of the vehicle. Then, the communication section 130 transmits the confidence factor to the server 14. In the server 14, a simple prediction section 146 selects the candidates of the vehicle satisfying the search condition on the basis of the search condition and the vehicle information transmitted from each one of multiple on-vehicle devices 12. A communication section 142 transmits the search condition to each one of the on-vehicle devices 12 of the vehicles selected as the candidates of the vehicle. Then, a vehicle search section 148 searches for the vehicle satisfying the search condition on the basis of the confidence factors transmitted from each one of the on-vehicle devices 12.SELECTED DRAWING: Figure 1 |
