This paper presents the new compact hybrid planetary transmission drive (CHPTD) as a solution of plug-in hybrid electric vehicle (PHEV). The presented CHPTD is more compact and lower costs than other seriesparallel hybrid drives equipped with planetary transmission and two motors. Proper architecture and elements were designed to achieve functions of PHEV. The powertrain and its components were optimized and determined by nonlinear dynamic modeling and simulations. Parameters of powertrain were adjusted and optimized by observation of simulation results. Two basic control strategies were analyzed to achieve minimum energy consumption and suitable operation range of battery state of charge. The very effective operation of the worked out powertrain was proved by tests in different driving conditions regarding city traffic and suburb area. The advantages of planetary transmission which is power summing mechanical unit, was obtained by proper design and control of innovative high energy saving electromagnetic clutch/brake device based on classic dual-diaphragm spring system.
