To provide a driving control device of a motor-mounted automobile that can accurately detect temperatures of switching elements of inverters.SOLUTION: A driving control device 16 of a motor-mounted automobile comprises two temperature detection parts 29 and 29, provided in any one of a plurality of switching elements 33 of an inverter 25a for driving one motor 6 and in any one of a plurality of switching elements 33 of an inverter 25a for driving the other motor 6, which detect temperatures of the switching elements 33 corresponding thereto respectively; and a temperature detection abnormality determination part 30 that compares the detected temperatures by the temperature detection parts 29 and 29 with each other to determine whether or not there is abnormality in the temperature detection parts 29. The temperature detection abnormality determination part 30, if a difference between the temperatures detected by the two temperature detection parts 29 and 29 is not in a predetermined range, determines that there is the abnormality in any of the temperature detection parts 29, when the motors 6 are not energized.SELECTED DRAWING: Figure 5

    【課題】インバータのスイッチング素子の温度を精度よく検出することができるモータ搭載自動車の駆動制御装置を提供する。【解決手段】このモータ搭載自動車の駆動制御装置16は、一方のモータ6を駆動するインバータ25aの複数のスイッチング素子33のいずれか一つ、および他方のモータ6を駆動するインバータ25aの複数のスイッチング素子33のいずれか一つに設けられて対応するスイッチング素子33の温度をそれぞれ検出する二つの温度検出部29,29と、温度検出部29,29で検出された温度を互いに比較することで各温度検出部29に異常があるか否かを判定する温度検出異常判定部30と、を備える。温度検出異常判定部30は、各モータ6の非通電時に、二つの温度検出部29,29で検出された温度の差が定められた範囲内に入っていないとき、いずれかの温度検出部29に異常があると判定する。【選択図】図5
