PROBLEM TO BE SOLVED: To determine a maintenance timing of a vehicular door closing device by capturing symptoms of a deterioration state or abnormality.SOLUTION: Data collected by data collection means is classified by a one-class SVM method, an abnormality degree is determined on the basis of the classified data, and whether or not the abnormality degree is larger than a prescribed threshold set in advance is determined. When the abnormality degree is determined to be smaller than the threshold, unnecessary of maintenance of a vehicular door closing device is displayed on a display device, and arithmetic processing of the data collected by the data collection means is performed by a main component analysis method so as to calculate a first main component and a second main component. Image data of a two-dimensional map is prepared on the basis of the first main component and the second main component, and a composite image of the image data of the two-dimensional map and image data of the two-dimensional map prepared on the basis of the data collected in a normal state is prepared. When the abnormality degree is determined to be larger than the threshold, the composite image is displayed on the display device. |
