<p>A method of operating a hybrid powertrain 105 comprising a motor-generator electric unit 500 and an internal combustion engine 110 connected to a transmission 540. The operating method comprises the steps of: determining an overall power to be delivered by the hybrid powertrain 105, monitoring a parameter indicative of a throttle pedal position, evaluating a predetermined gear shifting condition as a function of the parameter and of engine speed, splitting the overall power into a first contributing value of power to be delivered by the internal combustion engine 110 and a second contributing value of power to be delivered by the motor-generator electric unit 500, wherein the splitting of the overall power comprises the step of decreasing the first contributing power value, if the gear shifting condition is verified. The first contributing power value may be decreased by a value which represents a fuel economy opportunity and may be a function of a brake specific fuel consumption value of the engine 110. Reference is also made to a computer program, computer program product and control apparatus.</p> |
