1. An electrically operated vehicle driving controller, comprising:

  • 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;

    limit ratio calculation processing means for calculating a limit ratio for limiting the torque of the electrically operated machine on the basis of the driving section temperature;

    rotating speed calculation processing means for calculating the rotating speed of the electrically operated machine;

    limit torque calculation processing means for calculating an electrically operated machine limit torque on the basis of an electrically operated machine maximum torque set correspondingly to the rotating speed and the limit ratio;

    electrically operated machine target torque calculation processing means for calculating an electrically operated machine target torque showing a target value of the electrically operated machine torque; and

    correcting torque calculation processing means for correcting the electrically operated machine target torque on the basis of the electrically operated machine limit torque when the electrically operated machine target torque is greater than the electrically operated machine limit torque.
