CONTROL DEVICE FOR BELT-TYPE CONTINUOUSLY VARIABLE TRANSMISSION |
摘要 |
A control device for a belt-type continuously variable transmission CVT includes an engine 1, a belt-type continuously-variable transmitting mechanism 4; a forward/reverse switching mechanism 3 including a forward clutch 31 and a reverse brake 32; and a hydraulic control circuit 71 configured to control a pulley hydraulic pressure and engagement-element pressures for the forward clutch 31 and the reverse brake 32. The control device includes a selection control means for outputting a pulley hydraulic command to obtain an idle-time clamping pressure which is higher than an idle-time minimum pressure (idle-time MIN-pressure) calculated from an input torque, to the hydraulic control circuit 71, when the engine 1 is in operation during a selection of N-range. A position of an element clearance generated in the belt can be maintained even if drag torque is inputted. |
