Abstract

The functionality of a “Launch Control” is implemented in a hybrid vehicle, i.e. the hybrid vehicle can be accelerated to a maximum degree by starting the internal combustion engine immediately from the stationary state (S20), and acceleration takes place with the aid of the electric motor with full torque (S22) before a changeover to accelerating the internal combustion engine takes place (S24). The “Launch Control” differs from a further mode in which firstly acceleration takes place from the stationary state using a partial torque of the electric motor (S14), with the result that the internal combustion engine can be tow-started by means of the electric motor (S16) before a changeover to acceleration using the internal combustion engine (S18) occurs.
