Description

ABSTRACT:
A method for determining a shift point strategy in a hybrid vehicle includes providing at least two power sources, selectively coupling the two or more power sources to a hybrid vehicle transmission, defining an input shaft speed for best acceleration, defining an input shaft speed for best fuel economy, determining driver intent compared to the best acceleration and the best fuel economy, and setting a shift point of the hybrid vehicle transmission based, at least in part, on the driver intent.
