車両用自動変速機の制御装置
Document Type and Number:
Japanese Patent JP4270530
Kind Code:
B2
Abstract:
A changeover valve can be switched to a state in which a normally-open solenoid valve to normally control a control valve for a high speed transmission train controls a control valve for a low speed transmission train. An oil passage to switch the changeover valve this state is connected to an oil passage on an output side of the solenoid valve at a P or R position of a manual valve. When a system failure has occurred while a vehicle is running forward in the D, M position of the manual valve, the high-speed transmission train is established. At the time of the system failure, if the manual valve is switched to the R or P positions the changeover valve is switched to the above-described state. By then switching the manual valve to the D, M position, the low-speed transmission train is established.
