    • To provide a sensor abnormality determining apparatus that detects an abnormality of a temperature sensor for detecting a power element temperature, even when the difference between the power element temperature and the temperature of the cooling water for cooling the power element is low.
      This sensor abnormality determining apparatus is applied to an inverter (3) that is provided with: a power element (3a); a cooling water circulation path (42) having cooling water (41) for cooling the power element (3a) circulating therein; a temperature sensor (51) that detects a temperature of the power element (3a); and a water temperature sensor (52) that detects a temperature of the cooling water (41) circulating in the cooling water circulation path (42). The sensor abnormality determining apparatus is configured such that the apparatus is provided with: an abnormality determining section (5a), which determines that the temperature sensor (51) is abnormal when a temperature difference (AT) between the temperature detected by means of the temperature sensor (51) and the water temperature detected by means of the water temperature sensor (52) is larger than a previously set determination temperature difference; and a determination temperature setting section (5b) whereby the determination temperature difference for the time when the temperature detected by means of the temperature sensor (51 ) is lower than the water temperature detected by means of the water temperature sensor (52) is set at a lower value than the determination temperature difference for the time when the temperature detected by means of the temperature sensor (51) is higher than the water temperature detected by means of the water temperature sensor (52).
    • 为了提供一种传感器异常判定装置,其即使在功率元件温度和用于冷却功率元件的冷却水的温度之间的差异较小时,也检测用于检测功率元件温度的温度传感器的异常。 该传感器异常判定装置适用于具备功率元件(3a),功率元件 冷却水循环通路(42),其具有冷却在内部循环的动力元件(3a)的冷却水(41) 检测功率元件(3a)的温度的温度传感器(51); 以及检测在冷却水循环路径(42)中循环的冷却水(41)的温度的水温传感器(52)。 传感器异常判定装置构成为具备:异常判定部(5a),其在通过温度检测出的温度与温度差(ΔT)之间的温度差(ΔT) 传感器(51)和由水温传感器(52)检测到的水温大于预先设定的判定温度差; 以及判定温度设定部(5b),其中当由温度传感器(51)检测到的温度低于由水温传感器(52)检测到的水温时的判定温度差被设定为 比当温度传感器(51)检测到的温度高于利用水温传感器(52)检测到的水温时的判定温度差低。
