摘要:
The invention relates to a method and a device for operating a hybrid drive (1) of a vehicle, comprising a parallel hybrid drive train (2) having an internal combustion engine (3), at least one electrical machine (5), a shift element (4) interposed between the internal combustion engine (3) and the electrical machine (5), a tractive force interruption-shifting automated transmission (7) and a power take-off (25), the internal combustion engine (3) being frictionally connectible to the electrical machine (5) via the shift element (4) and being startable by means of the electrical machine (5). A coordinated sequence of functions with defined intermediate states is called up, a state of the shift element (4) for the synchronization of a transmission input (6) of the transmission (7) to a target transmission input speed being varied once the engine has been started, said synchronization being either purely electromotive or a combination of electrical machine and internal combustion engine.
摘要:
A method is described for starting an internal combustion engine of a hybrid drive having at least one electric drive. This drive can be coupled to the internal combustion engine via a first clutch for the pulse start of the engine. A speed change of the at least one electric drive occurring during the pulse start of the internal combustion engine is compensated for by continuously occurring changes of the transmission ratio in a vehicle transmission.
摘要:
A system and method for starting an ICE of a hybrid vehicle, the hybrid vehicle having a generator with a rotor rotating at an angular speed and a clutch provided between the ICE and the rotor. The method includes steps of disengaging the clutch so that the rotor and the ICE can operate independently; increasing the angular speed; upon the angular speed reaching a predetermined speed, engaging the clutch; allowing the ICE to crank; and starting the ICE.
