Map display device, navigation device and map display method
First Claim
1. A map display device comprising:
- a remaining energy acquiring unit for acquiring a residual quantity of energy for driving a mobile unit and equipment mounted on the mobile unit, operation of at least some of said equipment being controlled by a user through manipulation of an input unit of the equipment;
an input analyzer unit for analyzing the user'"'"'s manipulation of the input unit to determine changes in the operation of said at least some of said equipment;
a range calculating unit for computing a reachable range of the mobile unit with the residual energy the remaining energy acquiring unit acquires, using a moving energy consumption rate which is energy consumption per unit time required for moving the mobile unit and a driving energy consumption rate which is energy consumption per unit time required for driving the equipment mounted on the mobile unit; and
an output control unit for displaying the reachable range the range calculating unit computes,wherein the output control unit varies, when notified by said input analyzer unit of determined changes in the operation of said at least some of said equipment, the reachable range of the mobile unit computed by the range calculating unit in conformity with the determined changes in operation.
