PROBLEM TO BE SOLVED: To provide an electric car controller which can perform stable control even if noise (disturbance) is mixed in the pole position information of a rotor of a motor. SOLUTION: This electric car controller 30 has a position detecting means, which can obtain a detection value of a pole position of a rotor of a motor, and a control means 33 which controls the motor by using the pole position information. There is provided a pole position control means 34 which, when the disturbance with a prescribed level is detected by the position detecting means, controls the pole position information to eliminate the disturbance.
