Abstract:
A hybrid vehicle having a series-parallel architecture, i.e. a mechanic (gears) and an electric (generator (4), inverter (7), and motor (6)) propulsion chains associated by a planetary gear mechanism (2) powered by an engine (1). The generator rotor (4), with or without a flywheel (3), provides a kinetic energy storage due to its high inertia and speed. The stored energy is sufficient to drive simultaneously, the vehicle at low speed, and the not-fueled engine (1), during short periods. Between these periods, the fueled engine drives the vehicle and restores the stored kinetic energy. The succession of these periods made operation pulsatile at higher maximum power. Higher power means better efficiency. In addition, less pollution and perturbation compare to the “stop and start” are expected.
