This example shows the basic architecture of a parallel hybrid transmission. Electrical power is applied in parallel with the combustion engine power. The electrical torque is applied at the wheel axle, but it could also be applied to the engine flywheel. 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, battery and gearbox 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 power-split hybrid example sdl_power_split_hybrid and the series hybrid example sdl_series_hybrid.
