Title:

GEAR SHIFTING COMPLETION DETERMINATION DEVICE FOR AUTOMATIC TRANSMISSION

Document Type and Number:

WIPO Patent Application WO/2005/103529

Kind Code:

A1

Abstract:

A gear shifting completion determination device for an automatic transmission capable of rapidly performing gear shifting by properly determining the completion of the gear shifting. An ECT_ECU performs a program having a step (S114) for setting a determination time T for determining the completion of an up- shifting when an accelerator is released to a short determination time T (X) when a slip value NS (NS = NE - NT) between an engine rotational speed NE and a turbine rotational speed NT is smaller than a pre-determined slip valve NS (0) (when a difference between NT and NE is large, YES in S112) and a step (S120) for setting the determination time T to a long determination time T (Y) when the slip value NS (NS = NE - NT) is larger than the pre-determined slip value NS (0) (when the difference between NT and NE is small, NO in S112).
