CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

摘要

A control apparatus for automatic-transmission provided with input-clutch through which drive force generated by engine is input to automatic-transmission, released-side frictional coupling device being placed in released state to perform shifting action of automatic-transmission, and engaged-side frictional coupling device being placed in engaged state to perform shifting action, control apparatus including: first shifting mode control means including slipping means for placing input-clutch in released state, engaging means for placing input-clutch in engaged state, and releasing/engaging switching control means for controlling shifting action of automatic-transmission being performed in first shifting mode wherein released-side frictional coupling device is brought into released state, and engaged-side frictional coupling device is brought into engaged state, while input-clutch is placed in released or slipping state under control of slipping means, and input-clutch is then brought into engaged state under control of engaging means, with a change of operating speed of engine connected to input-shaft of automatic-transmission.

主权项

1. A control apparatus for an automatic transmission provided with an input clutch through which a drive force generated by an engine is input to the automatic transmission, a released-side frictional coupling device to be placed in a released state to perform a shifting action of the automatic transmission, and an engaged-side frictional coupling device to be placed in an engaged state to perform said shifting action, said control apparatus comprising:
first shifting mode control means including slipping means for placing said input clutch in a released state, engaging means for placing said input clutch in an engaged state, and releasing/engaging switching control means for controlling said shifting action of said automatic transmission so as to be performed in a first shifting mode in which said released-side frictional coupling device is brought into the released state, and said engaged-side frictional coupling device is brought into the engaged state, while said input clutch is placed in a released state or a slipping state under the control of said slipping means, and said input clutch is then brought into an engaged state under the control of said engaging means, with a change of an operating speed of said engine connected to an input shaft of said automatic transmission.
