|The development of Power Splitting Transmissions (PST) has been a crucial feature in the technological success of hybrid driveline vehicles. They have played a key role in facilitating the management of the mechanical and electrical power flows, ensuring good drivability, providing improved economy and reducing emissions compared to conventional internal combustion engine vehicles.
HEVs technology has made a massive impact over the past decade on the automotive engineering industry. The growth in interest has been fuelled by increasing concerns about the environment and fuel efficiency savings. But also, the market uptake of hybrid vehiclesâled mainly by the Toyota Priusâhas been much greater than most observers originally predicted; this in turn has led most of the other Original Equipment Manufacturers (OEMs) and Tier One suppliers to develop their own systems, often in collaborative partnerships.[Elmarakbi A, Ren Q, Trimble R, Elkady M (2013) Performance Analysis of Hybrid and Full Electrical Vehicles Equipped with Continuously Variable Transmissions]
