Driving device for electric vehicle and electric vehicle

Abstract

[PROBLEM] To provide a driving apparatus for use in electric vehicle, that is able to smoothly adjust a torque based on the rider's feeling while the electric vehicle is traveling based on an operation of an accelerator operator, that is excellent in ease of use and in riding comfort, and that is suitable for purposes intimately involved in daily lives. [SOLUTION] A driving apparatus for use in electric vehicle, the driving apparatus including: a rotating electric machine configured to drive a wheel that is rotatably mounted to a vehicle body; a hand-operated accelerator configured to be operated by the hands of a rider; an accelerator operation detection part that detects the amount of operation of the hand-operated accelerator; a current adjustment input member configured such that a torque used for adjustment of a current value supplied to the rotating electric machine is inputted to the current adjustment input member by the feet of the rider, at least part of the torque being transmitted to a wheel that is rotatably mounted to the vehicle body; a torque detection part that detects a torque transmitted from the current adjustment input member to the wheel; and a control device that supplies, to the rotating electric machine, a current in accordance with the amount of operation of the hand-operated accelerator detected by the accelerator operation detection part, the control device being configured to when a torque transmitted from the current adjustment input member to the wheel increases under a state where a current in accordance with the amount of operation of the hand-operated accelerator is being supplied to the rotating electric machine, increase a current supplied to the rotating electric machine in accordance with the amount of increase in the torque transmitted from the current adjustment input member to the wheel, and when a torque transmitted from the current adjustment input member to the wheel decreases under a state where a current supplied to the rotating electric machine is increasing, decrease a current supplied to the rotating electric machine in accordance with the amount of decrease in the torque transmitted from the current adjustment input member to the wheel.

Description

technical field [0001] The invention relates to a driving device for an electric vehicle and an electric vehicle. Background technique [0002] An electric vehicle includes an electric vehicle control device that supplies current to a rotating electrical machine according to the amount of operation of an accelerator operating element operated by a driver, and travels using the driving force generated by the rotating electrical machine. [0003] An electric vehicle has a battery as a power source. The distance that can run based on one charge is limited by the capacity of the storage battery. Therefore, compared with long-distance movement, electric vehicles are more suitable for short-distance movement. Furthermore, unlike a bicycle, an electric vehicle can travel by operating an accelerator operating element without stepping on a pedal. Therefore, as a more convenient means of transportation than bicycles, electric vehicles tend to be used for purposes closely related to...
