ROTARY ELECTRIC MACHINE CONTROL SYSTEM AND ROTARY ELECTRIC MACHINE CONTROL METHOD

摘要

A rotary electric machine control system (10) includes a rotary electric machine (second motor generator) (14), a number-of-revolutions sensor (34) that measures the number of revolutions per predetermined time period of the rotary electric machine (14), and a controller (32). The controller (32) has a threshold changing unit (48) for changing a control switching phase that is a control switching threshold to be used for switching the control mode of the rotary electric machine (14), according to a measurement result of the number of revolutions.
