Patent ID: 8412446

Claim:
A travel history collection system comprising a terminal side device and a center side device capable of communicating with the terminal side device, wherein the terminal side device includes: A) a vehicle travel history acquisition part for acquiring a travel history of a vehicle; B) a congestion section detection part for detecting a congestion section of the vehicle based on the travel history; C) a first short-range wireless communication part and a first wide-range wireless communication part for transmitting the travel history containing the congestion section to the center side device, C1) the first short-range wireless communication part transmitting the travel history to the center side device via at least one roadside device (C1-R), C2) the first wide-range wireless communication part transmitting the travel history to the center side device via a wide-range wireless communication antenna, C3) an antenna of the roadside device being closer to the terminal side device than the wide-range wireless communication antenna; and D) a travel history transmission part for D1) determining whether the travel history can be transmitted to the center side device via the first short-range wireless communication part based on a travel distance and/or a travel time period of the vehicle, and transmitting the travel history to the center side device via: D2) the first short-range wireless communication part when the first short-range wireless communication part is within a communication range of the at least one roadside device, and D3) the first wide-range wireless communication part D3-1) not immediately after the congestion section detection part detects the congestion section D3-2) but after the vehicle travels a predetermined distance (Llim) or a predetermined time period (Tlim) after the congestion section detection part detects the congestion section, D3-3) when the first short-range wireless communication part is out of the communication range of the at least one roadside device, and E) the center side device includes E1) a second wide-range wireless communication part and a second short-range wireless communication part for receiving the travel history transmitted from the terminal side device.
