<P>PROBLEM TO BE SOLVED: To provide a control device for an electric vehicle, which properly and promptly determines a failure of a motor or an inverter in an electric vehicle for effectively preventing the failure from continuing. <P>SOLUTION: An arithmetic result ∫(T<SP>*</SP>)<SP>2</SP>, which is obtained by square integration of a first torque estimation value obtained through torque computation from a current command value, is compared with an arithmetic result ∫(T)<SP>2</SP>, which is obtained by square integration of a second torque estimation value obtained through torque computation from an actual current, to determine the occurrence of a failure when the arithmetic results are separated by a predetermined threshold value Const. or more. <P>COPYRIGHT: (C)2011,JPO&INPIT |
