this example shows the basic architecture of a power-split hybrid transmission. the planetary gear, along with the motor and generator, acts like a variable ratio gear. in this test, the vehicle accelerates, maintains the faster speed, and then decelerates back to the original speed. the power management strategy uses just stored electrical power to effect the maneuver, the combustion engine only delivering the power required to maintain the original speed.

losses for the motor, generator, battery and planetary gear are modeled. you can use this system-level model to gain understanding of system performance, and to support design of the power management strategy. the example can be directly compared with the parallel hybrid example sdl_hybrid_parallel and the series hybrid example sdl_hybrid_series.
