Abstract
An object of the invention is to provide a visual recognition area estimation device that can accurately estimate an area recognized by a driver in real time. The visual recognition area estimation device of the present invention calculates the visual recognition area recognized by the driver by means of the visual recognition area calculation portionbased on the eyes of the driver, and estimates a time series visual recognition area as the area currently recognized by the driver by means of the visual recognition time space map creation portionbased on histories of a plurality of visual recognition areas calculated from the past to the present for a predetermined time. In this manner, by estimating the time series visual recognition area also including the past visual recognition area, the area currently recognized by the driver can be accurately estimated, and the eyes of the driver are not correlated with the obstacle but based on the standard area. Thus, it is possible to prevent the throughput from becoming too large, whereby the estimation processing in real time is possible.
