Abstract

A control device of an electric vehicle includes: an information acquiring portion acquiring information in a switching control of traveling modes of the electric vehicle and information on a gradient of an uphill road; a balanced driving force calculating portion determining that the electric vehicle is stopped on the uphill road in a motor traveling mode and calculating a balanced driving force (F) against a sliding-down force causing the electric vehicle to be slid down; a temperature change estimating portion estimating changes of temperatures of the motor (Tm) and the inverter (Ti); a time calculating portion calculating a drivable time (tm) until the temperature of the motor reaches a motor-side upper limit allowable temperature (TmL) and an energizable time (ti) until the temperature of the inverter reaches an inverter-side upper limit allowable temperature (TiL); and a mode switching portion switching the motor traveling mode to another traveling mode.
