DRIVE SYSTEM AND METHOD OF DRIVING A VEHICLE

摘要

A drive system and a method of driving a vehicle (1). The drive system has a combustion engine (2), a brake device (24) with which the vehicle (1) can be braked, an electric machine (9), an energy storage (20) which is connected to the electric machine, at least one assembly (22) which is operated by electric energy, a planetary gear which comprises a sun wheel (10), a ring wheel (11) and a planet wheel holder (12). At an operation occasion when the vehicle (1) is stationary, no driving moment (Tg) is demanded by the vehicle (1) and the coupling member (15) is in the first position (I1), a control unit activates the brake device (24) with a braking moment (Tb) such that the vehicle (1) is maintained in a stationary position at the same time as it controls the electric machine (9) such that it supplies a moment (Tel) which results in that the electric machine (9) generates so much electric effect (Eel) that operation of the assembly (22) is maintained.
