Steuergerät für hydraulisch gesteuertes Fahrzeuggetriebe

摘要

Manual speed changing is performed in a shorter time without giving rise to shocks. For that purpose, at the time of manual speed changing, a hydraulic pressure QUPON of a hydraulic engaging element on the engaging side is corrected by boosting. A correction value QUPONX before starting of an inertia phase and a correction value QUPONY after starting of the inertia phase are separately set. By making QUPONX > QUPONY, the time required for manual speed changing as well as the shocks at the time of speed changing are reduced.
