Abstract
There is provided a route guidance apparatus including a route search unit which searches for at least one route, to a predetermined destination, which is to be traveled by an electric vehicle propelled by electric power stored in a secondary battery provided within the vehicle, and a power consumption calculation unit which calculates power consumption of the electric vehicle when a route to a destination, which was searched for by the route search unit, is traveled by the electric vehicle, based on information on electric power to be consumed when the electric vehicle travels and geographical information relating to the route.
Claims15
A navigation device for an electric vehicle comprising:
- at least one processor configured as a route search unit;
- a recording unit including gradient information for a road recorded therein;
- a power information holding unit including electrical power consumption information of the electric vehicle per gradient angle and regenerative electrical energy information of the electric vehicle per gradient angle;
- a current location acquisition unit including a current location of the electric vehicle;
- and
- a navigation control unit,
- wherein the navigation control unit calculates electrical power consumption of the electric vehicle, which was searched for by the route search unit, based on the gradient information, the electrical power consumption information of the electric vehicle per gradient angle, and the regenerative electrical energy information of the electric vehicle per gradient angle, and
- wherein the at least one processor is configured to cause a display unit to display a route to the destination with at least electrical power consumption to the destination according to a remaining amount of electric power of the battery.
A navigation method for an electric vehicle comprising:
- searching, by at least one processor, for at least one route;
