PROBLEM TO BE SOLVED: To provide an inverter-cooling pump control apparatus, and a vehicle, which are capable of improving the life of an inverter while preventing a decrease in life of an inverter-cooling pump.SOLUTION: A control apparatus 70 of an inverter-cooling pump 60 includes a pump control part 71 for controlling, with pulse width modulation control, the inverter-cooling pump 60 that cools an inverter 40 with a coolant, the inverter electrically connected to a motor 20 for providing a vehicle 1 with power. Further, in a case where a temperature of the inverter 40 is higher than a given temperature, the pump control part 71 drives the inverter-cooling pump 60 at a first duty ratio and, in a case where the temperature of the inverter 40 is equal to or lower than the given temperature, drives the inverter-cooling pump 60 at a second duty ratio smaller than the first duty ratio.SELECTED DRAWING: Figure 1

    【課題】インバータ冷却用ポンプの寿命の低下を抑制しつつ、インバータの寿命を向上させることができるインバータ冷却用ポンプの制御装置及び車両を提供する。【解決手段】インバータ冷却用ポンプ60の制御装置70は、車両1の動力用のモータ20に電気的に接続されたインバータ40を冷媒で冷却するためのインバータ冷却用ポンプ60をパルス幅変調制御で制御するポンプ制御部71を備え、ポンプ制御部71は、インバータ40の温度が所定温度より大きい場合に、インバータ冷却用ポンプ60を第1のデューティ比で駆動させ、インバータ40の温度が所定温度以下の場合に、インバータ冷却用ポンプ60を第1のデューティ比よりも小さい第2のデューティ比で駆動させる。【選択図】図1
