Abstract
Method for potentiating an engine's power contribution to a hybrid electric vehicle's performance in a take-off operating condition is disclosed. Normally, fuel injection to, and ignition at the engine are only commenced when the engine is operating at a speed exceeding the resonance speed of the drive train to reduce engine start harshness; such resonance speeds of the drive train being dictated, at least in part, by transmission backlash, softness and the like. During high driver acceleration demands, however, ignition and the injection of fuel is desirably started as early as possible to potentiate output power and acceleration.
