Example Embodiment

[0016] figure 1 The hybrid driver HA in the series basically includes a supply unit 10 and a drive unit 20. The supply unit 10 is composed of an internal combustion engine 12 and a generator 14. The internal combustion engine 12 and the generator 14 are coupled by a force transmission connection 16. The drive unit 20 is composed of an electric motor 22 and a drive train 24. The electric motor 22 and the drive train 24 are coupled by a force transmission connection 26.

[0017] The energy transfer unit 30 is connected to the generator 14, the electric motor 22 and the storage battery 32 via wires 34, 36 and 38. The generator 14, the electric motor 22, and the storage battery 32 may operate as an energy source or as an energy reducer.

[0018] The supply unit 10 is used for this purpose, namely to supply electric energy to a vehicle unit, such as a drive unit 20. To this end, the generator 14 is driven by the internal combustion engine 12. The generator 14 converts the mechanic...

Abstract

The invention relates to a method for operating a hybrid drive. The method for operating the hybrid drive of a motor vehicle in particular. An internal combustion engine is connected to a generator via a force-conducting connection. In a learning mode, the generator is operated as a motor and drives the internal combustion engine. In this learning mode, a so-called zero quantity calibration is performed.

Description

technical field [0001] The invention relates to a method for operating a hybrid drive, in particular a hybrid drive of a motor vehicle, according to the preamble of claim 1 . Background technique [0002] A known series of hybrid drives drives the motor vehicle via an electric motor. The electrical energy for the electric motor is provided by a generator using the internal combustion engine. [0003] It is also known that motor vehicles are exclusively driven by an internal combustion engine. It is also known for such motor vehicles that the coasting phase, that is to say the passive drive of the internal combustion engine, is used to carry out a so-called null calibration. In this case the determination and adaptation of the operating parameters of the internal combustion engine, ie the operating parameters during normal operation of the internal combustion engine, then results in compensation of aging drift and optimization of the efficiency of the internal combustion en...
