Abstract

A check point calculation unit evaluates the driving of a driver in a travel segment where a host vehicle has traveled and extracts a check point where the driving evaluation does not meet a predetermined evaluation standard, thereby obtaining data representing a point in the travel segment where the driving evaluation is lowered. An advice generation unit provides maneuver support to the driver on the basis of the check point. When there is the check point in the traveling direction host vehicle, the advice generation unit provides maneuver support at the check point such that the driving evaluation by the check point calculation unit meets a predetermined evaluation standard, thereby improving the driving evaluation at the check point where the driving evaluation is low and improving the driving evaluation as a whole.
