Beschreibung
Zusammenfassung:	An electric vehicle comprises a motor controller for controlling the electric motor in such a manner that the motor controller executes a control routine to perform torque control of the electric motor when the shifting state detecting device detects that the driving power transmission path is in the driving power transmission state, and executes a control routine to perform rotational speed control of the electric motor, when the shifting state detecting device detects that the driving power transmission path is in the driving power cut-off state; wherein in the rotational speed control, the rotational speed of the electric motor is controlled such that an angular velocity of an upstream rotary member in a shifting location of the driving power transmission path estimated by the estimating device gets close to an angular velocity of a downstream rotary member in the shifting location; wherein when the driving power transmission path is shifted from the driving power cut-off state to the driving power transmission state, the motor controller switches the rotational speed control to the torque control after performing predetermined transit control; and wherein the motor controller controls the electric motor such that a change rate of the torque output from the electric motor which occurs until the torque output from the electric motor reaches target torque demanded by a rider is made less in the transit control than in the torque control.
