<P>PROBLEM TO BE SOLVED: To provide a technology which can properly secure the insulation performance of motors, in an electric vehicle mounted with the first motor whose internal air pressure is held substantially equal to outside air pressure and the second motor whose internal pressure is held lower than the outside air pressure. <P>SOLUTION: This electric vehicle comprises: the first motor; the second motor; a motor voltage control device which controls voltages of the first motor and the second motor; a drive force control device which controls drive forces of the first motor and the second motor; an atmosphere pressure sensor; and a second motor temperature sensor. The motor voltage control device adjusts a motor voltage so that the motor voltage is lowered as a detection value of the atmosphere pressure sensor becomes large. The drive force control device adjusts a distribution ratio of the drive forces between the first motor and the second motor so that the drive force of the first motor is increased and the drive force of the second motor is decreased as the detection value of the second motor sensor becomes large. <P>COPYRIGHT: (C)2013,JPO&INPIT |
