PROBLEM TO BE SOLVED: To provide a control device of an electric motor for a vehicle capable of supplying an electric current corresponding to driving force demanded by a driver to the electric motor even when an electric current sensor to detect an electric current value supplied to the electric motor, etc. fail. SOLUTION: This control device 1 is furnished with a functional defect detection part 20B to detect a defect of an electric current value detection function of the electric current sensors 15FR to 10RL, a front and rear force computation part 20D to find front and rear force of wheels 10FR to 10RL in accordance with a steering angleδ, etc. of steering 21 in the case when a functional defect of the electric current sensors 15FR to 15RL is detected, an electric current value estimation part 20E to estimate an electric current value supplied to the electric motors 11FR to 11RL in accordance with the front and rear force F of the wheels 10FR to 10RL and a control part 20C to control the electric current value supplied to the electric motors 11FR to 11RL so that an estimated electric current value If and a target electric current value It match with each other in the case when the functional defect of the electric current sensors 15FR to 15RL is detected.
