Abstract
A hybrid vehicle and method of control are disclosed wherein the ratio of engine speed to vehicle speed varies continuously in some operating conditions and is controlled to be one of a finite number of preselected ratios in other operating conditions. The transition from continuously variable mode to discrete ratio mode includes selecting a virtual gear number and increasing the engine speed to the corresponding ratio to vehicle speed. Once in a discrete ratio mode, the virtual gear number can vary automatically in response to changes in vehicle speed or in response to driver activation of shift selectors.
