A drivable distance calculation device calculates a drivable distance that the vehicle equipped with the device can travel. The drivable distance calculation device includes a remaining battery capacity sensor which calculates a remaining capacity of a battery installed in the vehicle; and a arithmetic unit which calculates multiple power consumption ratios for different units of driving in accordance with variations in the remaining battery capacity calculated by the remaining battery capacity sensor and calculates the drivable distance based on the remaining battery capacity calculated by the remaining battery capacity sensor and a power consumption ratio selected from among the calculated multiple power consumption ratios.

Drivable distance calculation device and drivable distance calculation method

A travelable area display device according to the present invention is configured to compute a travelable distance from an optional spot, specify a feature spot which a driver can recognize on die basis of accumulated movement history information of a vehicle, and simultaneously display on a map in an in-vehicle screen a travelable area which is specified by the travelable distance, and the specified feature spot.
