电动机系统的控制装置及温度检测状态判定方法
摘要：
本发明获得一种即使在转矩指令为0的状态持续的情况下也能够判定用于电动机系统的温度检测部的温度检测状态的电动机系统的控制装置及温度检测状态判定方法。本发明构成为：获取流过电动机系统的电动机装置的相电流值，并且获取温度检测部检测出的温度检测值，运算通过对相电流值超过第1相电流阈值的部分进行累计而得到的第1相电流累计值、以及通过对相电流值低于第1相电流阈值以下的第2相电流阈值的部分进行累计而得到的第2相电流累计值中的至少一个来作为相电流累计值，开始进行温度检测状态的判定之后对温度检测部检测出的温度检测值的变化、以及运算出的相电流累计值的变化进行确认，由此来判定温度检测状态。
摘要（英）：

A temperature detection condition of a temperature detection unit used in a motor system is determined by: obtaining a phase current value flowing through a motor device and obtaining a temperature detection value; calculating, as an integrated phase current value, at least one of a first integrated phase current value, which is obtained by integrating an amount by which the phase current value exceeds a first phase current threshold, and a second integrated phase current value, which is obtained by integrating an amount by which the phase current value is smaller than a second phase current threshold that is equal to or smaller than the first phase current threshold; and determining an amount of variation in the temperature detection value detected by the temperature detection unit following the start of determination of the temperature detection condition and an amount of variation in the calculated integrated phase current value.
