Straddle-type electric vehicle, power unit, and method for controlling power unit

摘要

An electric vehicle 1 includes an electric motor 12, a transmission 14 to which a driving force of the electric motor 12 is transmitted, a wheel 6 to which the driving force of the electric motor 12 is transmitted via the transmission 14, a rotation speed aequisition unit 41 that acquires motor rotation speed M of the electric motor 12, and further includes a target motor power determination unit 31 that determines a target motor power W of the electric motor which is desired to be output from the electric motor 12 regardless of a transmission gear ratio G of the transmission 14, a target motor torque calculation unit 32 that calculates a target motor torque t that is obtained by dividing the target motor power W by the motor rotation speed M, and a motor control unit 33 that drives the electric motor 12 at the target motor torque t.
