Abstract
An electrically operated vehicle driving controller has an electrically operated machine driving section for operating an electrically operated machine; a driving section temperature detecting section for detecting the driving section temperature of the electrically operated machine driving section; a limit ratio calculating processor for calculating a limit ratio for limiting the torque of the electrically operated machine on the basis of the driving section temperature; a rotating speed calculating processor for calculating the rotating speed of the electrically operated machine; and a limit torque calculating processor for calculating an electrically operated machine limit torque corresponding to an electrically operated machine maximum torque set corresponding to the rotating speed on the basis of the limit ratio. Because the torque of the electrically operated machine is limited in a limit ratio corresponding to the temperature of the electrically operated machine, it is possible to prevent the characteristics of the electrically operated machine from being reduced.
