Flood detection device, flood detection system, flood detection program storage medium, and flood detection method

Abstract

The invention relates to a flood detection device, a flood detection system, a flood detection program storage medium, and a flood detection method. The flood detection device includes a detection result acquisition section, a weather information acquisition section and an identification section. The detection result acquisition section acquires a detection result that, on the basis of a pluralityof kinds of running state data relating to running of a vehicle, detects flooding of a road on which the vehicle is running. The weather information acquisition section acquires weather information including at least one of rainfall information representing a measured rainfall amount in a region in which the vehicle is running or rainfall estimation information representing an estimated rainfallamount. The identification section uses the respective acquisition results of the detection result acquisition section and the weather information acquisition section to identify flooding of the road.

Description

technical field [0001] The disclosure relates to a flood detection device, a flood detection system, a flood detection program storage medium, and a flood detection method. Background technique [0002] Roads may be flooded due to heavy rainfall or the inflow of rainwater from other places. As techniques for detecting such flooding of roads, techniques disclosed in JP-A-2004-341795 and JP-A-2012-216103 have been proposed, for example. [0003] In Japanese Patent Application Laid-Open No. 2004-341795, it is proposed that a vehicle is provided with a water flooding sensor configured to detect the presence of a liquid tangible object to detect road flooding, send the detection result to a central server, and send a detection result to other vehicles. It is determined not to guide the detour route through the impassable flooded route. [0004] In Japanese Patent Application Laid-Open No. 2012-216103, it is proposed to predict the amount of rainfall at the position where the ve...

Problems solved by technology

[0005] However, in the technique of Japanese Patent Laid-Open No. 2004-341795, a flooding sensor is required, and there is still room for improvement in order to more easily determine flooding.

[0006] In addition, in the technology of Japanese Patent Laid-Open No. 2012-216103, even if the amount of rainfall is the same, all drivers do not necessarily operate the wipers at the same wiper speed. In order to accurately detect flooding, there is an improvement room for
