An electric rolling stock control device includes a voltage controlling unit for controlling an output voltage of an inverter and a speed estimating unit for calculating a rotation speed estimation value of an electric motor. The speed estimating unit includes an initial speed estimating unit for outputting an initial speed estimation value, a steady speed estimating unit for outputting a steady speed estimation value, a correction coefficient calculating unit for calculating a correction coefficient based on the steady speed estimation value and a backup speed, and a correction speed calculating unit for storing the correction coefficient in a storage unit and calculating a correction speed by multiplying the correction coefficient by the backup speed.
