Abstract
A hybrid powertrain includes a combustion engine operable to output rotational power thereat, an electric machine arrangement operable to output rotational power thereat, a gearbox arrangement for receiving rotational power from at least one of the combustion engine and the electric machine arrangement and being operable to couple motive power to a load coupled to the gearbox arrangement. The gearbox arrangement is operable to provide a plurality of gearing ratios. The electric machine arrangement is employable to extend a rotation rate range provided in a given gearing ratio: at higher rotation rates prior to a gear change from said given gearing ratio to a gearing ratio subsequent thereto; or at both lower rotation rates when accelerating from a standstill or from a preceding gear, and at higher rotation rates prior to a gear change from said given gearing ratio to a gearing ratio subsequent thereto.
