To provide a rotary electric machine control device which so makes electromagnetic noise, which can be generated when driving a rotary electric machine, as to be less noticeable.SOLUTION: A rotary electric machine control device (40) is applied to a vehicle (100) comprising an internal combustion engine (101), a rotary electric machine (20), and inverters (31, 32) which drive the rotary electric machine. This control device comprises a PWM control part (40) which generates PWM pulse on the basis of a carrier wave, outputs said PWM pulse to the inverter, and controls the rotary electric machine. A fundamental frequency of the carrier wave is set according to a frequency within a prescribed frequency setting range at which a sound pressure level of noise, which is generated in the vehicle in which the internal combustion engine is in a prescribed drive state and the rotary electric machine is in a prescribed power generation state, is equal to or higher than a threshold value.SELECTED DRAWING: Figure 1
【課題】回転電機を駆動する場合に発生しうる電磁騒音を目立たなくさせる回転電機の制御装置を提供すること。【解決手段】回転電機の制御装置(40)は、内燃機関(101)と、回転電機(20)と、回転電機を駆動させるインバータ(31,32)と、を備える車両(100)に適用される。この制御装置は、搬送波に基づいてPWMパルスを生成し、インバータに対して当該PWMパルスを出力して、回転電機を制御するPWM制御部(40)を備える。そして、所定の周波数設定範囲内の周波数であって、内燃機関が所定の駆動状態であり、かつ、回転電機が所定の発電状態である車両において発生する騒音の音圧レベルが閾値以上となる周波数に合わせて、搬送波の基本周波数が設定されている。【選択図】 図1
