An object is to provide a travel environment analysis apparatus that accurately estimates an event occurring outside of a vehicle. A travel environment analysis apparatus includes a gaze point concentration area detector, a gaze point concentration area event estimation unit, and an information output unit. The gaze point concentration area detector sequentially detects a gaze point concentration area that is an area outside of a plurality of vehicles and gazed by occupants of the plurality of vehicles, based on line-of-sight information related to lines of sight of the occupants. The gaze point concentration area event estimation unit estimates, when a new gaze point concentration area which is a gaze point concentration area newly coming up is detected, an event occurring in the new gaze point concentration area. The information output unit outputs information of the new gaze point concentration area and information of the event.

An automatic driving control plan creator creates a plan of an automatic driving section where a subject vehicle is automatically driven, and a plan of a driving switching preparation section for switching the subject vehicle from automatic driving to manual driving. A driving load calculator predicts, for each point of the driving switching preparation section, a driving load applied to a driver when the driver manually drives the subject vehicle. A driving switching permission determiner extracts, from the driving switching preparation section, a switching-inhibited section that is a section where switching from automatic driving to manual driving is not permitted, on the basis of the predicted driving load at each point. A driving switching preparation section compensator changes a start point of the driving switching preparation section so as to lengthen the driving switching preparation section in accordance with the length of the switching-inhibited section.

Automatic driving control planning apparatus and automatic driving control planning method

An automatic driving control plan creation unit creates a plan of an automatic driving section in which a subject vehicle is automatically driven, and a plan of a driving switching preparation section for switching the subject vehicle from automatic driving to manual driving. For each point in the driving switching preparation section, a driving load calculation unit calculates a driving load applied to a driver when the driver manually drives the subject vehicle. A driving switching permission determination unit permits switching of the subject vehicle from automatic driving to manual driving at a point where the driving load is smaller than a predetermined threshold value, and does not permit switching of the subject vehicle from automatic driving to manual driving at a point where the driving load is equal to or larger than the threshold value. A permission standard relaxation unit makes the driving load difficult to exceed the threshold value.

A navigation system capable of enabling a user to use navigation functions such as route guidance without setting a destination. It includes an information recording unit for storing a driving history, a destination estimating unit for estimating a destination from the driving history stored in the information recording unit, a route computing unit for calculating a route to the destination estimated by the destination estimating unit, and an information display unit for causing the route calculated by the route computing unit to be displayed.
