  • Operating method for a hybrid vehicle
    Patent number: 11117568
    Abstract: An operating method for a hybrid vehicle having at least two drive engines, of which the first drive engine is a combustion engine with internal combustion and can be supplied with fuel from a first energy storage device, and a second drive engine, which can be supplied with energy from a second energy storage device. In order to determine a control command with which the first drive engine can be shut off the method includes determining a state value for the filling degree of the first energy storage device. The method also includes detecting a filling degree of the second energy storage device, and comparing said state value for the filling degree to a target state value. Depending on said comparison, the method also includes determining a control command for the first drive engine.
