Abstract:
1. A vehicular information collecting system composed of a vehicular communication system mounted in a vehicle and a server, the vehicular communication system, comprising: a vehicular receiving element configured to receive a multicast tagged with information of a designated area; a communication controlling element configured to collect information denoting a state of the vehicle as a probe information from an output signal of a sensor mounted in the vehicle; a vehicular transmitting element configured to transmit the probe information collected by the communication controlling element to a server; and a position determining element configured to determine a position of the vehicle, the server comprising: a multicast generating element configured to generate the multicast; a server transmitting element configured to transmit the multicast to the vehicle served as a subject; a server receiving element configured to receive the probe information transmitted from the vehicle; and an analyzing element configured to analyze the probe information received by the server receiving element, wherein the multicast generating element is configured to generate the multicast tagged with content of a designated part, which is a part of a vehicular identifier for identifying each of the vehicles, and the communication controlling element is configured to transmit the probe information to the vehicular transmitting element on condition that a present position of the vehicle determined by the position determining element is located in the designated area included in the multicast and that content of a designated part which is a part of the vehicular identifier inherent in the vehicle is matched with content of the designated part included in the multicast; and the multicast generating element is configured to adjust content of the designated part of the vehicular identifiers so as to adjust the number of vehicles served as the subject for collecting the probe information.
