Abstract
A navigation apparatus for use in a hybrid vehicle in which an engine and a drive motor are used in combination acquires a current SOC value of a battery, geometry of roads around the vehicle, gradient information, traffic information, learning information, and so forth. A travelable range of the vehicle after the battery is charged is calculated for each of a plurality of various charge times on the basis of the acquired information. The plurality of calculated travelable ranges is simultaneously displayed on a liquid crystal display. It is thus possible to display a minimum charge time required to travel to a destination in a manner easily understandable to a user.
Claims9
A map display apparatus comprising:
- a display device that displays a map of an area around a vehicle;
- a battery remaining amount acquisition device that acquires a remaining amount of a battery that supplies electric power to a motor that produces a drive force for the vehicle;
- a calculation condition acquisition device that acquires, of a first calculation condition for calculating a range in which the vehicle can perform one-way travel as a travelable range and a second calculation condition for calculating a range in which the vehicle can perform round-trip travel as a travelable range, a currently set calculation condition as a condition for calculating a travelable range;
- a travelable range calculation device that calculates a travelable range, wherein the vehicle can perform one of one-way travel and round-trip travel after the battery is charged depending on the calculation condition acquired by the calculation condition acquisition device, for each of a plurality of various charge times on the basis of the remaining amount of the battery acquired by the battery remaining amount acquisition device;
- and
- a travelable range display device that simultaneously displays on the display device a plurality of travelable ranges calculated by the travelable range calculation device and the charge times respectively corresponding to the plurality of travelable ranges.
