<p>PROBLEM TO BE SOLVED: To provide a vehicle operation state estimation device capable of precisely estimating operation state of a driver made on an operation element.SOLUTION: The vehicle operation state estimation device calculates a period of time between inflection points which is a period of time between two inflection points based on inflection points in operation amount made on an operation element within a preset time t1, and stores the calculated period of time between the inflection points. The vehicle operation state estimation device further calculates a time median as a median of the period of time between the two inflection points corresponding to the preset time t1. When it is determined that the calculated time median is smaller than a centroid value of a set of the stored inflection point times made on the operation element, the vehicle operation state estimation device estimates that a driver is relatively in concentration to the operation on the operation element.</p> |
