Shift control method for six-speed automatic transmission

摘要

A shift control method for a gearset with greater than or equal to 5 speeds, allowing to perform a sequential shift and a multi-skip shift in relation to the multi-shift stages, contributing to an improved response during shifting. The shift control method comprises steps of performing a preceding shift control when disengagement components of a preceding shift stage and a final target shift stage are identical during skip shifting, then executing a one-stage skip control toward the final target shift stage if a certain set of required conditions are satisfied; and standing by for a predetermined time period without performing the preceding shift control when the disengagement components of the preceding shift stage and the final target shift stage are different during skip shifting, then performing a one-stage skip control toward the final target shift stage only if pertinent conditions are met.
