发明名称 Anomaly detection apparatus for automatic transmission
摘要 One embodiment of the present invention provides an anomaly detection apparatus for an automatic transmission, the automatic transmission including an electrically-operated oil pump that is rotationally driven by an electric motor, including: a solenoid that is capable of switching a line pressure of a hydraulic control circuit that controls the automatic transmission between a high pressure and a low pressure; and an oil pressure switch that is turned on or off in response to the line pressure, wherein, in response to an oil pressure command value, whether the oil pressure switch is turned on or off according to the oil pressure command value is determined, and the determination and a load state of the electrically-operated oil pump are compared so as to distinctively determine in which of the solenoid and the oil pressure switch, an anomaly has occurred.
