A control device for controlling a motor of an electrical vehicle is provided with a motor control circuit 7 having a first calculation control circuit 11 and a second calculation control circuit 12. In operation, the motor control circuit 7 allows the first and second calculation control circuits 11, 12 to respectively calculate motor control commands It*, Im* and Its*, Ims* on the basis of inputted identical driving condition. The circuit 7 compares the motor control commands It*, Im* calculated by the first calculation control circuit 11 with the motor control commands Its*, Ims* by the second calculation control circuit 12, respectively. When a difference between the calculated commands It* and Its* and another difference between the calculated commands Im* and Ims* are equal to or more than a predetermined value, then the motor control circuit 7 outputs a stop command to stop an operation of the motor. |
