摘要： A method for operating a motor vehicle including a drive mechanism having at least a first drive unit and at least a second drive unit is provided. The method includes providing a drive torque directed at the driving of the motor vehicle in a first setting of the drive mechanism only by means of the second drive unit and in a second setting by means of both drive units, wherein upon exceeding a start-up threshold value by a demanded preset power there is a switching from the first setting to the second setting, and upon falling below a shut-off threshold value by the demanded preset power there is a switching from the second setting to the first setting. It is provided that the start-up threshold value and/or the shut-off threshold value is determined in dependence on a driving resistance of the motor vehicle and/or a vehicle weight of the motor vehicle. A motor vehicle employing the method is also provided.

摘要： A motor vehicle, including a drivable front axle, a drivable rear axle, an internal combustion engine, an automatic transmission coupled thereto, and a switchable torque distribution unit which is coupled to the automatic transmission and enables all-wheel drive, which torque distribution unit is coupled to the front axle and the rear axle. A torque generated by the internal combustion engine can be directed from the torque distribution unit either to the front or rear axle or distributed to both axles. An electric machine is provided which is coupled to the rear axle. A torque generated by the electric machine which is provided to the rear axle is provided to the torque distribution unit via the coupling and can also be provided from this torque distribution unit to the front axle.

摘要： A method for operating an exhaust system of a vehicle having an internal combustion engine upstream of the exhaust system and having an energy network is provided. The method includes operating the energy network in an operating situation with a voltage at a starting position, wherein a heating element is associated with the exhaust system, the heating element being connected to the energy network via a switching element, wherein the heating element in a first switching state of the switching element, when the switching element is switched on, is connected to the energy network in an electrically conductive manner, and in a second switching state of the switching element, when the switching element is switched off, is electrically separated from the energy network, and changing the voltage from the starting position to a switchover position when switching the switching element between the first and second switching states.

摘要： A method for operating a brake system for a motor vehicle, wherein the brake system comprises an eddy current brake mechanically coupled to at least one wheel of the motor vehicle for providing a braking force acting on the wheel, wherein an electric machine is mechanically coupled or can be coupled to the wheel and is electrically connected to the eddy current brake. In this case, it is provided that, in an emergency braking mode for braking the wheel, the eddy current brake is supplied in parallel with energy provided by means of the electric machine operating as a generator and with electrical energy taken from an energy accumulator. The disclosure furthermore relates to a brake system for a motor vehicle.

摘要： A method for operating a motor vehicle, with a drive device for providing a driving torque as well as a detection device for detecting at least one other motor vehicle up ahead. An automatic length guidance of the motor vehicle is carried out. In this case, it is provided that, in the framework of the length guidance, a distance of the motor vehicle from the other motor vehicle is adjusted to a nominal distance. The nominal distance corresponds to a distance setting at constant distance, and starting from the distance setting, it is increased in the event of a distance change resulting from a positive acceleration of the other motor vehicle, and it is reduced in the event of a distance change resulting from a negative acceleration of the other motor vehicle.
