Abstract

A method for operating a hybrid drivetrain for a motor vehicle. Power is provided by an internal combustion engine in a first operating mode. Power is provided by an electric machine in a second operating mode. A change from one operating mode into the other operating mode is carried out according to the state of at least one of the drivetrain and the motor vehicle. The change of operating mode is controlled according to at least one switching variable, which is a function of a requested power target value.

Description

technical field [0001] The invention relates to a method for operating a hybrid drive train of a motor vehicle, wherein in a first operating mode the power is provided by an internal combustion engine, and in which in a second operating mode the power is provided by an electric machine, wherein switching from one operating mode to the other A changeover to an operating mode is carried out depending on the state of the motor vehicle and / or the drive train. Background technique [0002] In the field of drive trains for motor vehicles, so-called hybrid drive trains have long been known. Such a hybrid drive train has a first transmission unit in the form of an internal combustion engine for generating drive power, and a second transmission unit comprising an electric machine arrangement. [0003] In addition to so-called mild-hybrid designs in which the electric motor is only used to assist the internal combustion engine, full-hybrid designs are also known. In this full hybrid...
