First Claim
1. A vehicle comprising:
- an electric motor for driving drive wheels of the vehicle;
a battery for supplying electric power to said electric motor;
a motor drive control unit for controlling the electric motor driving the vehicle by controlling electric power transfer from the battery to the electric motor;
battery residual capacity detection means for detecting actual residual charge of the battery;
input means for inputting schedule information including route information pertaining to a travel route for a trip;
schedule information memory means for storing said schedule information;
provisional position memory means for storing geographic information, included in said schedule information, relating to geographic positions between a starting location where the battery is charged and a destination having facilities for recharging the battery;
distance calculating means for calculating total distance from the starting location to the destination, based on the geographic information stored in said provisional position memory means; and
power consumption programming means for, prior to the start of the trip, scheduling consumption of electric power by said electric motor in accordance with distance travelled, based on the total distance calculated by said distance calculating means and the detected residual capacity of the battery.

Abstract
A vehicle, which is either an electric vehicle or a hybrid vehicle, capable of achieving low-pollution emissions and saving energy by maximizing use of the capacity of the battery. A navigation ECU receives input identifying a starting location where the battery is charged, a stopover location, and a destination where battery recharging is planned, and calculates travel distances from the starting location to the stopover location and to the destination based on geographic data for the starting location, the stopover location and the destination, and schedules electric power consumption corresponding to distance travelled, based on the respective calculated distances, to assign a battery residual capacity usage value for each leg of the trip. A vehicle ECU supplies electric power from the battery to the motor in accordance with that schedule.
