Abstract: 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.

Abstract: In a map display apparatus, a display processor causes a display to display a map based on map information. A priority object setting unit determines a priority object having higher priority than other objects contained in the map. A scroll processor scrolls the map displayed on the display in step with a scroll operation performed by a user. In a case where the priority object is located outside the map displayed on the display, the operating feel controller adds directivity to an operating feel imparted to the scroll operation in such a manner that a scroll operation for scrolling the map toward the priority object and a scroll operation for scrolling the map in any other direction arouse different operating feels.
