自动变速器的控制装置
摘要：
本发明涉及自动变速器的控制装置，其目的在于能够以简单的结构恰当地检测用于检测收容在自动变速器内的工作油的温度的温度检测装置的故障，能够有效地防止因该温度检测装置发生故障而导致自动变速器发生控制不良的情况，其特征在于包括：第一温度检测装置(3)，检测收容在自动变速器内的工作油的温度；自动变速器控制单元(4)，设置在与上述工作油的收容部同一气氛中；第二温度检测装置(5)，检测上述自动变速器控制单元(4)的温度；故障判定部(8)，通过比较由第二温度检测装置(5)检测出的自动变速器控制单元(4)的温度与由上述第一温度检测装置(3)检测出的工作油的温度来判定上述第一温度检测装置(3)是否发生了故障。
摘要（英）：

In order to enable, with a simple configuration, the appropriate detection of malfunctions in a temperature detection means that detects the temperature of operating oil housed in an automatic transmission, and to effectively prevent control defects occurring in the automatic transmission due to a malfunction in said temperature detection means, this control device for an automatic transmission is equipped with a first temperature detection means (3) that detects the temperature of operating oil housed in the automatic transmission, and an automatic transmission control means (4) arranged in an atmosphere identical to that of the housing unit for the aforementioned operating oil, and is characterized by being equipped with a second temperature detection means (5) that detects the temperature of the automatic transmission control means (4), and a malfunction determination unit (8); that determines whether a malfunction has occurred in the first temperature detection means (3) by comparing the temperature of the automatic transmission control means (4) detected by the second temperature detection means (5) and the temperature of the operating oil detected by the first temperature detection means (3).
