Abstract
A hybrid vehicle and method of control are disclosed. An internal combustion engine and at least one traction motor are operated such that the combined output torque corresponds to one of a plurality of output torque functions, each output torque function having a distinct output torque at a maximum value of accelerator pedal position for an associated vehicle speed. The output torque function is selected based on a virtual gear number. The virtual gear number varies in response to driver activation of shift selectors or automatically in response to changes in vehicle speed.
