Betriebsverfahren and apparatus for controlling a motor operation of an electric machine of a mild Hybridantriebs a Kraftfahrzeugs

The invention relates to an operating method for controlling a motor operation of a motor and a generator operable electric machine of a mild hybrid drive of a motor vehicle, wherein the electric machine is adapted to drive an internal combustion engine of the motor vehicle at least at times and to produce electrical energy in a recuperation. The invention further relates to a device that is configured to perform the operating procedure. According to the operation process, a decision as to whether and / or with which power a motor operation of the electric machine is carried out during the journey in order to relieve a motor torque of the internal combustion engine of the motor vehicle, in dependence on current values ​​of at least one operating parameter (21) of the determines the motor vehicle and as a function of previous driving operation data (22). In this way, the fuel economy of the mild hybrid system can be increased by using otherwise unusable energy.
