Abstract
A driving apparatus allowing two motors to drive a same driving shaft is provided. When a voltage command value is less than a predetermined threshold, a control unit outputs driving command values based on one control pattern such that a direction of a torque of one of the motors becomes different from a driving direction of the driving shaft. Also, when the voltage command value becomes greater than or equal to the predetermined threshold, the control unit outputs the driving command values based on another control pattern, such that the direction of the torque of the one of the motors becomes the same as the driving direction of the driving shaft when the voltage command value is greater than or equal to the predetermined threshold, and does not become different from the driving direction of the driving shaft when the voltage command value drops below the predetermined threshold.
