Title:
路面情報収集システム
Document Type and Number:
Japanese Patent JP7037736
Kind Code:
B2
Abstract:
To provide a road surface information collection system capable of corresponding to a rapid change of a road surface state.SOLUTION: A road surface information collection system includes: multiple vehicles for collecting basic data of road surface unevenness information; and a data center for analyzing basic data acquired from the vehicles via radio communication so as to constitute road surface unevenness information and distributing the information via radio communication. The system can perform a rapid change correspondence function in such manners that: basic data including vibration data and position information is transmitted to the data center when the vibration data being equal to or more than a predetermined threshold is detected by the vehicle in a place where existing road surface unevenness information does not exist; the data center that has received the basic data performs a transmission request of the basic data to subsequent vehicles passing through the position; the threshold is substantially canceled in the subsequent vehicles that have received the transmission request; and the basic data is transmitted from all the subsequent vehicles passing through the position to the data center.SELECTED DRAWING: Figure 6
