Electrically assisted vehicle

摘要

An electrically assisted vehicle includes a vehicle body, pedals to input human power, a crank that is coupled to the pedals and freely rotatably supported on the vehicle body, a wheel (i.e., at least one wheel) that is attached to the vehicle body and rotates according to a rotation of the crank, a first electric motor that is attached to the vehicle body and drives the wheel, a second electric motor that is attached to the vehicle body and drives the wheel or another wheel, a torque detection unit that detects a torque applied to the crank, a torque command value calculation unit, and a motor drive unit that drives the first electric motor and second electric motor according to a calculated torque command value. The torque command value calculation unit calculates a first torque command value for the first electric motor and a second torque command value for the second electric motor according to a torque detected by the torque detection unit, and calculates the first and second torque command values such that the first and second torque command values are mutually shifted in phase.
