Hybrid vehicle with smoothing and cylinder deactivation

摘要

A hybrid vehicle comprises an internal combustion engine (20 see fig 1) and an electric machine (10 see fig 1), which is preferably a motor-generator. At least one cylinder of the engine (20) may be selectively switched off. Preferably two or more cylinders are switched off in an alternating pattern. The electric machine (10) is controlled to counteract and damp rotational fluctuations arising from the switching off of some of the cylinders. A partial moment produced by the electric machine (10) may be controlled in response to an ascertained value of the rotational non-uniformity. The engine (20) and electric machine (10) may be connected to each other in a mechanically variable manner.
