Abstract

A map display device includes a position information acquiring unit for acquiring the present position of a vehicle; a map data storage unit for storing map data; a remaining energy acquiring unit for acquiring a residual quantity of energy for driving the vehicle and equipment mounted on the vehicle; a range calculating unit for computing a range the vehicle can travel with the remaining energy, using a moving energy consumption rate which is energy consumption per unit time required for moving the vehicle and a driving energy consumption rate Eci which is energy consumption per unit time required for driving the equipment mounted on the vehicle; and an output control unit for displaying the range on a map using the map data.

Claims

1. An apparatus for outputting a reachable range of a mobile unit comprising:

a processor to execute a program;

and

a memory to store the program which, when executed by the processor, results in performance of steps comprising,

acquiring a residual quantity of energy for driving a mobile unit and equipment mounted on the mobile unit, operation of at least one of said equipment being controlled by a user through manipulation of an input unit of the equipment,

computing a reachable range of the mobile unit with the residual energy acquired, using a moving energy consumption which is required for moving the mobile unit and a driving energy consumption which is required for driving the equipment mounted on the mobile unit; and

outputting the reachable range computed,

wherein the processor varies the outputted reachable range in a manner that accounts for the operation of at least one of said equipment.

2. The apparatus for outputting a reachable range of a mobile unit according to claim 1, wherein the steps further comprise:

outputting a message proposing to change the setting of the equipment mounted on the mobile unit.

3. The apparatus for outputting a reachable range of a mobile unit according to claim 1, wherein the steps further comprise:

outputting another reachable range corresponding to another setting of the equipment mounted on the mobile unit.

4. A method for outputting a reachable range of a mobile unit comprising:

acquiring a residual quantity of energy for driving a mobile unit and equipment mounted on the mobile unit, operation of at least one of said equipment being controlled by a user through manipulation of an input unit of the equipment,

computing a reachable range of the mobile unit with the residual engery acquired, using a moving energy consumption which is required for moving the mobile unit and a driving energy consumption which is required for driving the equipment mounted on the mobile unit; and

outputting the reachable range computed,

wherein the outputted reachable range varied in a manner that accounts for the operation of at least one of said equipment.

5. The method for outputting a reachable range of a mobile unit according to claim 4, wherein further comprises:

outputting a message proposing to change the setting of the equipment mounted on the mobile unit.

6. The method for outputting a reachable range of a mobile unit according to claim 4, wherein the steps further comprises:

outputting another reachable range corresponding to another setting of the equipment mounted on the mobile unit.
