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 from 15 m/s to 20 m/s, and then decelerates back to 15 m/s. The power management strategy uses just electrical power to effect the maneuver, the combustion engine only delivering the power required to maintain a steady 15 m/s.
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_parallel_hybrid and the series hybrid example sdl_series_hybrid.
