A drive device, which controls the driving of an electric motor, which is a power source of an electric vehicle, carries out the following processing, so as to respond immediately to the driver's operations while preventing major damage to the electric motor. Specifically, when the torque command value provided by the host controller changes suddenly, the drive device determines whether the torque command value and acceleration/deceleration command as well as the current torque value and acceleration/deceleration status satisfy predetermined conditions. If the conditions are satisfied, the drive device controls the electric motor with the internal torque command value as zero, and then, as time passes, causes the internal torque command value to approach the torque command value provided by the host controller. |
