To provide an inverter device and a vehicle control device that can thermally protect a switching element without making the switching element larger than necessary, and at the same time can secure sufficient torque to go over an uphill or a step.SOLUTION: This inverter device 13 is equipped with an inverter 31 and an inverter control unit 5 that controls the inverter 31. The inverter control unit 5 has a torque limiting unit 40 that limits the torque of a motor 6 by a torque limit value. The torque limit value includes a torque limit value corresponding to the rotation speed determined by the rotation speed of the motor 6, and a short-time high torque limit value that limits the torque at a high torque that can be output by the motor 6 only for a short time. When the motor 6 is started, the torque limiting unit 40 uses the larger value of the torque limit value corresponding to the rotation speed and the short-time high torque limit value for the torque limit.SELECTED DRAWING: Figure 2

    【課題】スイッチング素子を必要以上に大きくすることなく、スイッチング素子を熱的に保護すると共に、上り坂または段差等を超えるのに十分なトルクを確保することができるインバータ装置および車両制御装置を提供する。【解決手段】このインバータ装置13は、インバータ31と、インバータ31を制御するインバータ制御部5とを備える。インバータ制御部5は、モータ6のトルクをトルク制限値でトルク制限するトルク制限部40を有し、前記トルク制限値として、モータ6の回転数によって定められた回転数対応トルク制限値と、短時間のみモータ6が出力可能な高トルクで前記トルクを制限する短時間高トルク制限値とがある。トルク制限部40は、モータ6の始動時においては、回転数対応トルク制限値と、短時間高トルク制限値のうち、大きい方の値を前記トルク制限に用いる。【選択図】図2
