Abstract: To remedy the imperfection of the existing power-split type of multi-energy powertrain based on a planetary mechanism for HEV (Hybrid Electric Vehicle), and to increase the power transmittability, efficiency and variable speed range of the CVT (Continuously variable transmission) used with it, a new power-split type of HEV powertrain is here put forward and studied. The working principle of this type of mechatronic assembly is analysed in detail and general and key points for its design and realisation are also discussed. Its technical features and applied perspective are thus revealed.

Keywords: continuously variable transmission; HEVs; multi-energy powertrain; power splitter; hybrid electric vehicles; CVT; HEV powertrain; mechatronics; mechatronic assembly.
