Title:
自動変速機の制御装置
Document Type and Number:
Japanese Patent JP5625105
Kind Code:
B2
Abstract:
A first hydraulic pressure control unit forms an oil path to supply oil to a frictional engagement element when a select lever is located in a travel range or between the travel range and a non-travel range and forms an oil path to discharge the oil from the frictional engagement element when the select lever is located in the non-travel range. An abnormality determination unit cancels an abnormality determination when only a travel range signal is output from a range signal output unit after a signal of the range signal output unit is determined to be abnormal, and maintains the abnormality determination when only a non-travel range signal is output from the range signal output unit. A second hydraulic pressure control unit forms an oil path to supply the oil to the frictional engagement element during the abnormality determination or when only the travel range signal is output, and forms an oil path to discharge the oil from the frictional engagement element before the abnormality determination or when only the non-travel range signal is output.
