To provide a vehicular temperature adjustment system that can suppress increase of friction losses of a rotary electric machine and a gear box.SOLUTION: A vehicular temperature adjustment system 10 comprises: a first temperature adjustment circuit 61 that performs temperature adjustments of an electrical motor 20 and a transmission 40; a second temperature adjustment circuit 62 that performs temperature adjustments of a power conversion device 50; a heat exchanger 63 the performs heat exchange between a first temperature adjustment medium and a second temperature adjustment medium; and a control device ECU. The second temperature adjustment circuit 62 comprises a valve device 626 that adjusts flow volumes of the second temperature adjustment medium to the heat exchanger 63, and the power conversion device 50 comprises a PDU 51 that supplies the electrical motor 20 with electric power. The control device ECU controls carrier frequencies of the PDU 51 and the valve device 626, on the basis of a temperature of the first temperature adjustment medium. In the case that the temperature of the first temperature adjustment medium is less than a predetermined value, the control device ECU makes the carrier frequencies lower and controls the valve device 626 so that flow volumes of the second temperature adjustment medium into the heat exchanger 63 become less, in comparison with the case that the temperature of the first temperature adjustment medium is above or equal to the predetermined value.SELECTED DRAWING: Figure 1

    【課題】回転電機及びギヤボックスのフリクションロスの増加を抑制することができる車両用温調システムを提供する。【解決手段】車両用温調システム10は、電動機20や変速装置40の温調を行う第1温調回路61と、電力変換装置50の温調を行う第2温調回路62と、第1温調媒体と第2温調媒体との熱交換を行う熱交換器63と、制御装置ECUとを備える。第2温調回路62は熱交換器63への第2温調媒体の流量を調整するバルブ装置626を備え、電力変換装置50は電動機20へ電力を供給するPDU51を備え、制御装置ECUは第1温調媒体の温度に基づいて、PDU51のキャリア周波数及びバルブ装置626を制御し、第1温調媒体の温度が所定値未満である場合には、第1温調媒体の温度が所定値以上である場合に比べて、キャリア周波数を低くするとともに、熱交換器63への第2温調媒体の流量が少なくなるようにバルブ装置626を制御する。【選択図】図1
