Abstract
An auxiliary device system includes a motor generator, an auxiliary device motor, a converter configured to convert electric power generated by the motor generator, an inverter configured to drive the motor generator and the auxiliary device motor, a switch configured to be switched between a motor generator control state in which the inverter controls the motor generator and an auxiliary device motor control state in which the inverter controls the auxiliary device motor, and a controller configured to control the switch. When a condition in which a motor generator drive command is generated is satisfied, the controller sets the switch to the motor generator control state. When the condition is not satisfied, the controller sets the switch to the auxiliary device motor control state.
