Shift control method for preventing starting stage engagement failure of hybrid electric vehicle

摘要

When a hybrid electric vehicle in which an automatic manual transmission (AMT) is equipped stops and then re-starts, when a starting stage of the AMT is not implemented, an RPM of a driving motor which is directly connected to an input shaft is changed so that a torque applied to an input shaft of the AMT is increased or decreased, and thus even though a blocking phenomenon occurs when an AMT-HEV stops and then re-starts after an engine re-starts, the torque transferred from the driving motor to the input shaft is appropriately increased and decreased and thus a gear restricted to the input shaft differently rotates from a synchronizer.
