Method for operating a motor vehicle with a hybrid drive, which includes an internal combustion engine connected to an exhaust system of the motor vehicle along with at least one traction electric motor, which is operated via an electric energy accumulator of the motor vehicle and can be coupled to the internal combustion engine, wherein the motor vehicle can be moved via the internal combustion engine and/or the traction electric motor, wherein when movement of the motor vehicle via the internal combustion engine is switched to movement of the motor vehicle solely via the traction electric motor, and the internal combustion engine is decoupled from the traction electric motor, operation of the internal combustion engine is continued, dependent upon at least one piece of exhaust system information describing a condition of the exhaust system.

Method for operating a motor vehicle with hybrid drive, and motor vehicle with hybrid drive

A method for operating a hybrid electric vehicle including an electric machine, a battery and an internal combustion engine, the load point of which is shifted upward to drive the electric machine for charging the battery in the generator mode, wherein a target state of charge of the battery is specified; a required target charging capacity is determined; the load point of the internal combustion engine initially is only shifted upward within an engine-map range of the internal combustion engine.
