A method for controlling a hybrid drivetrain of a motor vehicle such that, during a thrust operation of the vehicle, a change takes place from a combustion-powered driving mode, in which the combustion engine is in a thrust operation, the separator clutch is engaged and the electric machine contributes no force, or from a combined driving mode in which the engine is in a thrust operation, the clutch is engaged and the electric machine operates as a generator, to an electric driving mode in which the engine is switched off, the clutch is disengaged and the electric machine operates as a generator. To efficiently change driving modes, the clutch is partially disengaged to a slip limit; the clutch is then completely disengaged; and when the clutch reaches the slip limit, the generator torque of the electric machine is increased inversely to the torque that can be transmitted by the clutch.

The invention claimed is: 1. A method of controlling a hybrid drivetrain of a motor vehicle, in which the motor vehicle has, arranged in series, a combustion engine (VM), a separator clutch (K), an electric machine (EM) that is operable as a motor and a generator, and a drive transmission which is d
The invention claimed is: 1. A method of controlling a hybrid drivetrain of a motor vehicle, in which the motor vehicle has, arranged in series, a combustion engine (VM), a separator clutch (K), an electric machine (EM) that is operable as a motor and a generator, and a drive transmission which is drivingly connected, on an output side thereof, with a drive axle of the motor vehicle such that, during a thrust operation of the motor vehicle, a change takes place either from a combustion-powered driving mode in which the combustion engine (VM) is in a thrust operation, the separator clutch (K) is engaged and the electric machine (EM) does not contribute any driving no force, or from a combined driving mode in which the combustion engine (VM) is in the thrust operation, the separator clutch (K) is engaged and the electric machine (EM) operates as a generator, to an electric driving mode in which the combustion engine (VM) is turned off, the separator clutch (K) is disengaged and the electric machine (EM) operates as a generator, the change to the electric driving mode, during the thrust operation of the motor vehicle, is carried out by the method comprising the steps of:commencing disengagement of the separator clutch (K) up to a slip limit;disengaging the separator clutch (K) from the slip limit until the separator clutch (K) is completely disengaged; andfrom the slip limit until the separator clutch (K) is completely disengaged, increasing generator torque (MEM) by a same amount as the reduction of torque (MK) that is transmitted by the separator clutch (K) when the separator clutch (K) is being disengaged.
