Abstract
This suppresses increased vehicle vibration and noise. [Solution] The electric vehicle comprises a motor, an inverter that drives the motor, and a control device capable of performing pulse torque control, which controls the inverter using a control torque command whose pulse period is the sum of the non-zero torque time and the zero torque time. When performing pulse torque control, the control device makes the pulse frequency, which is the reciprocal of the pulse period, variable.
