| 摘要 |
A drive system (2) for a motor vehicle (1) has a transmission (11) for driving at least one drive axle (13, 14) of the motor vehicle (1). An internal combustion engine (3) optionally is connected operatively to the transmission (11) or decoupled therefrom. A first electric machine (17) optionally is connected operatively to the at least one drive axle (13, 14) or to an output shaft (39) of the transmission (11) or decoupled therefrom. A second electric machine (19) is connected operatively to the internal combustion engine (3). |

1. A drive system for a motor vehicle, having: a transmission for driving at least one drive axle of the motor vehicle; an internal combustion engine that is selectively connected to the transmission or decoupled therefrom, the internal combustion engine having a crankshaft and a starter ring gear; a first electric machine that is selectively connected to the at least one drive axle or to an output shaft of the transmission or decoupled therefrom, the first electric machine further being configured to operate as a motor and as a generator; a second electric machine that is connected to the crankshaft of the internal combustion engine by a belt drive, the second electric machine being configured to operate as a starter for warm starting of the internal combustion engine and as a generator; and a third electric machine having a pinion that is selectively connected to the starter ring gear for cold starting of the internal combustion engine. |
