Patent ID: 8360929

Claim:
A method for operating a hybrid drive arrangement with an internal combustion engine having a drive shaft, the internal combustion engine comprising a throttle valve; an electric drive having a drive shaft; a coupling arranged between the internal combustion engine and the electric drive and controllable on demand in such a way that the drive shaft of the internal combustion engine and the drive shaft of the electric drive are coupled to one another in a torque-engaged manner; the method comprising: detecting whether there is a requirement to interconnect the drive shaft of the internal combustion engine and the drive shaft of the electric drive; if there is a requirement to interconnect: pilot-controlling the speed of the internal combustion engine to a target speed level in such a way that the drive shafts of the internal combustion engine and of the electric drive run at least approximately synchronously, the speed of the internal combustion engine being pilot-controlled by a default of a setpoint for an opening angle of the throttle valve; subsequent regulation of the speed of the internal combustion engine in such a way that the drive shafts of the internal combustion engine and of the electric drive run substantially synchronously; subsequent coupling of the drive shafts of the internal combustion engine and of the electric drive via the coupling.
