Title:
HYDRAULIC CONTROLLER OF AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2007/119549
Kind Code:
A1
Abstract:
In clutch-to-clutch up shift, occurrence of inertia shock is suppressed while
engine racing is prevented. In response to a first sweep control where the engaging
side sweeps up toward a target hydraulic pressure (PTA), the release
side hydraulic pressure (PB) sweeps down in an initial control. When
the release side hydraulic pressure (PB) moves into such a state (fPB(0)+PKEEP+PLS2T)
as providing a minute torque capacity, a sustention control at an extremely gentle
gradient δPB is carried out so as to be substantially sustained
at the hydraulic pressure, and a sweep down control continues at a gentle gradient
δPE2 up to release after starting of rotational variation.
