Abstract
Drive system, especially for a motor vehicle, with a drive assembly, especially an internal combustion engine (1), an electric machine (4) and an antislip control, in which the (one) electric machine (4) is designed such that it can produce a reduction of drive slip, in particular by braking action and/or—when the electric machine (4) is acting as a coupling—by clutch slip action.
Claims8
A drive system for a motor vehicle, comprising:
- a drive system in the form of a combustion engine (1);
- at least one electrical machine (4) coupled with a drive shaft (10), and
- an acceleration slip control,
- wherein the electrical machine (4) is an inverter-controlled three-phase machine arranged in such a way as to permit drive slip reduction by decreasing the drive torque,
- wherein the inverter (17) has an intermediate circuit on a voltage level higher than that of the on-board electrical system, and
- a power storage device (19, 25) on the voltage level of the intermediate circuit which at least partially stores the electrical energy gained during the reduction in drive torque.
