A recognition timing estimation device configured to estimate a timing of a driver's recognizing action related to a subsequent travel segment of a plurality of travel segments that constitute a traveling course of a vehicle, is provided. The device includes a processor configured to execute a traveling information acquiring module to acquire information related to a driving operation of a driver or the traveling course, a travel segment estimating module to estimate a pause between the travel segments based on the information acquired by the traveling information acquiring module, an eye detecting module to detect a behavior of a driver's eye, and a recognition timing estimating module to estimate the timing of the driver's recognizing action based on a temporal relationship between the pause between the travel segments estimated by the travel segment estimating module and the behavior of the eye detected by the eye detecting module.

Method and device for estimating recognition timing

A driving assist device is provided, which includes a processor configured to execute an inference module to infer that a timing of a line-of-sight movement or blink detected by a camera near a predicted timing is a timing of a recognizing action of a driver for a subsequent travel segment of a plurality of travel segments that constitute a traveling course of a vehicle, an information providing module to provide the driver with assisting information for the subsequent travel segment before the timing of the recognizing action inferred by the inference module, and a providing timing changing module to change a providing timing of the assisting information according to a quantity of the assisting information.
