<p><P>PROBLEM TO BE SOLVED: To perform a smooth starting operation without misjudging a system to be abnormal, when a driver operates the vehicle starting switch of an electric car. <P>SOLUTION: The electric car has: a drive motor which drives the vehicle, a high-voltage condensing device which supplies the drive motor with power; and a high-voltage circuit which connects the high-voltage condensing device with the motor for drive, and the high-voltage circuit is switched into a conductive state and a break state by a main relay 36. It is arranged so that the signals of a vehicle starting switch 38 operated by a driver and an accelerator pedal sensor 44 are sent to a vehicle control unit (EVCU)32 as a motor control means, and the driver is informed that the drive motor is in an undrivable state by a speaker 49 as a vehicle state informing means, when an accelerator is operated, in a state the high-voltage circuit is switched into a break state by the main relay 36. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
