Patent ID: 7463962

Claim:
A method for determining a shift point strategy, comprising: providing at least two power sources; selectively coupling a hybrid vehicle transmission having an input shaft to said at least two power sources, said hybrid vehicle transmission receiving power from said power sources; defining a speed of said transmission input shaft to promote an acceleration as compared to a fuel economy; defining a speed of said transmission input shaft to promote said fuel economy as compared to said acceleration; determining driver intent to promote either of said acceleration and said fuel economy; and setting a shift point based, in part, on at least said determining step, wherein said shift point is variable based on said determining step; and wherein said setting of said shift point comprises setting an unscheduled up shift point and an unscheduled downshift point for an engaged gear of said hybrid transmission; and wherein said determining driver intent to promote either of said acceleration and said fuel economy includes assessing a gear position indication to promote one of said acceleration and said fuel economy.
