Abstract

The invention relates to a non-railbound land vehicle (2) comprising a drive system with the following components; a combustion engine-generator unit (=VG unit) (14, 16); at least one electric drive motor (18, 20); a power control station (30) for the electric motor that can be operated by the driver of the vehicle and a control electronics (24) that is connected to the VG unit, the electric motor and the power control station. The invention is characterized in that the control electronics is configured and can operate in such a way that it reduces temporarily the electrical power demanded by the electric motor and/or at least one secondary current consumer for the transition from one operating phase with a first power state of the electric motor and/or at least one secondary current consumer (26) of the vehicle to an operating phase with a higher, second power state of the electric motor and/or at least one secondary current consumer in order to attain fster transition of the combustion engine (14) from a first power output to a higher second power output.
