Abstract

[PROBLEM] To provide a driving apparatus for use in electric vehicle that is able to suppress uncomfortableness felt by a rider because of a fluctuation in the acceleration, and at the same time able to output an adequate torque under a low speed and a high load, and additionally able to prolong a possible travel distance of the electric vehicle obtainable per charging. [SOLUTION] A driving apparatus for use in electric vehicle, the driving apparatus including: a rotating electric machine including a permanent magnet, the rotating electric machine driving a wheel that is rotatably mounted to a vehicle body; an accelerator operator configured to be operated by a rider; an accelerator operation detection part that detects a state of the accelerator operator; a current control input member configured to be operated by the rider; a current control input detection part that detects a state of the current control input member; and a control device that supplies a current from a battery to the rotating electric machine in accordance with an output of the accelerator operation detection part, the control device being configured to, at least under a low speed and a high load, supply a current from the battery to the rotating electric machine in such a manner that, when an operation the rider performs on the current control input member is detected by the current control input detection part, a high current value and a low current value are alternately repeated in the rotating electric machine in accordance with an output of the current control input detection part and additionally in such a manner that the high current value exceeds a current value that has been supplied to the rotating electric machine in accordance with the output of the accelerator operation detection part at a time point of state shifting from a state where a current is supplied from the battery to the rotating electric machine in accordance with the output of the accelerator operation detection part to a state where the high current value and the low current value are alternately repeated in the rotating electric machine in accordance with the output of the current control input detection part.
