<P>PROBLEM TO BE SOLVED: To provide an electric vehicle for preventing unintended deceleration from occurring even when a trouble occurs in an inverter. <P>SOLUTION: The control device of a hybrid electric vehicle includes: a motor to be driven by electric power supplied from a battery mounted in the vehicle; an induced voltage control unit for suppressing and controlling an induced voltage developed by the rotation of the motor to be equal to or lower than a voltage of the battery; a motor rotation count control unit for controlling the number of rotations of the motor on the basis of a requested drive torque requested from the vehicle; and a generated drive torque calculation unit for calculating a generated drive torque for traveling the vehicle from the requested drive torque and the number of rotations of the motor. The motor rotation count control unit sets the maximum number of rotations so that the induced voltage developed in the motor is equal to or lower than the voltage of the battery and controls the number of rotations of the motor so as to be equal to or less than the maximum number of rotations, when the induced voltage control unit cannot suppress and control the induced voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
