Title:
SHIFTING PATH CONTROL METHOD FOR SIX-SPEED AUTOMATIC TRANSMISSION
Document Type and Number:
Japanese Patent JP2004183889
Kind Code:
A
Abstract:

To provide a shifting path control method of a 6-speed automatic transmission having at least five speeds by realizing multiple gear shift speeds in which not only the successive gear shifts but also more multiple skip shifts can be performed to enhance the gear shift responsiveness.

If release elements of a preceding gear shift speed and a finally determined gear shift speed are identical, the preceding transmission control is performed, and one-shift skip control is performed to the finally determined gear shift speed only when the applicable condition is satisfied. If the release elements between the preceding gear shift speed and the finally determining gear shift speed are different from each other during the skip shift, waiting is performed without performing the preceding gear shift speed control for a predetermined time, and one-shift skip control to the finally determined gear shift speed is performed only when the applicable condition is satisfied.
