Abstract
A method for operating a hybrid vehicle, particularly one that includes both a primary and an auxiliary power source. According to one exemplary embodiment, the method seeks to decouple or disassociate a driver's engagement of an accelerator pedal with activation of an auxiliary power source, such as an internal combustion engine. This way, if the driver aggressively engages the accelerator pedal while the hybrid vehicle is being propelled by a battery and an electrical motor, the method will delay activation of the internal combustion engine so that the two events do not appear to be linked or connected to one another. Delaying activation of the internal combustion engine while the electric motor is under a heavy stress load may also improve the drive quality of the hybrid vehicle.
