  • Patent number: 11619188
    Abstract: A method for heating a first exhaust gas purification device and a second exhaust gas purification device of an exhaust system of an internal combustion engine of a motor vehicle, has the following steps: determining a first actual temperature of the first device and a second actual temperature of the second device, determining a first setpoint temperature of the first device and a second setpoint temperature of the second device by means of a heating coordination device, determining a first heat demand of the first device and a second heat demand of the second device, creating a heating specification for the first device and for the second device, relaying the heating specification to an engine control device of the motor vehicle, and controlling the internal combustion engine by means of the engine control device as a function of the heating specification.

  • Patent number: 11519343
    Abstract: A method for operating an internal combustion engine of a drive system for a motor vehicle, the internal combustion engine being designed for operation using various types of fuel, has the following steps: querying operating parameters of fuel-relevant functions of the drive system by means of a central fuel coordination device of a central engine coordination device, determining possible types of fuel for operating the internal combustion engine, based on the queried operating parameters and predefined fuel release conditions, by means of the central fuel coordination device, selecting a type of fuel for operating the internal combustion engine, based on the determined possible types of fuel and at least one predefined selection criterion, by means of the central fuel coordination device, transmitting information identifying the selected type of fuel from the central fuel coordination device to a central engine control unit of the central engine coordination device, and operating the internal combustion engi

  • Patent number: 11118529
    Abstract: A drive system for driving a motor vehicle has an internal combustion engine and an operating mode coordination device for determining and controlling the operating mode of the internal combustion engine. The drive system has a function coordination device for coordinating secondary functions of the drive system, the function coordination device being designed for generating, based on the coordination of the secondary functions, an operating mode request for the operating mode coordination device for controlling the operating mode of the internal combustion engine, and transmitting it to the operating mode coordination device. The invention further relates to a motor vehicle having a drive system, and a method for operating a drive system of a motor vehicle.
