<P>PROBLEM TO BE SOLVED: To achieve a motor control proper in response to the operation state of a power supply for travelling by a simple configuration. <P>SOLUTION: In an electric vehicle 1, a torque-current command value Iq<SP>*</SP>to a motor 10 and an excitation-current command value Id<SP>*</SP>are adjusted by the voltage (a power-supply voltage) of a DC power supply line 40. That is, since an output voltage range and a maximum output power at a time when each of power supply devices (power supply from a fuel cell 50, an electric storage device 60 and a stringing wire) is operated singly are designed to differ from device to device, the operation state of each power supply device can be estimated from the power-supply voltage without requiring a new component, and the motor 10 is controlled in conformity with the maximum output power of the power supply devices thus estimated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
