ROTATING ELECTRIC MACHINE CONTROL SYSTEM

摘要

To provide a rotary electric machine control system for a hybrid system including a pair of rotary electric machines that are supplied with electric power from a common battery to respectively serve as a generator and a motor, in which components from the battery to an inverter are reliably protected by preventing an over-current. A rotary electric machine control system includes torque limitation means for limiting an output torque of a rotary electric machine, and battery electric power abrupt variation estimation means for estimating that battery electric power is in an abrupt variation state in which the battery electric power is varying abruptly on the basis of at least one of a variation rate of the battery electric power and a variation rate of a rotational speed of the rotary electric machine. The torque limitation means changes, in the case where the battery electric power abrupt variation estimation means estimates that the battery electric power is in the abrupt variation state, a mode of limitation of the output torque from a mode of limitation of the output torque used in a non-abrupt variation state in which the battery electric power is not varying abruptly.
