  • Publication number: 20250010855
    Abstract: A method for operating a motor vehicle, which includes a drive system, including an electric drive machine, a friction braking system and an actuating element. The actuating element is continuously movable between a first end state and a second end state, a position of the actuating element in the first end state corresponding to a percentage value of 0%, and the position of the actuating element in the second end state corresponding to a percentage value of 100%. An acceleration torque for the motor vehicle is predefined if the positon has a percentage value that is greater than a predefined threshold value, and a deceleration torque for the motor vehicle being predefined if the position has a percentage value that is less than the threshold value. The friction braking system is activated in such a way that the friction braking system generates at least partially the predefined deceleration torque.

  • Patent number: 9885334
    Abstract: A method for operating an electric machine coupled to an internal combustion engine in a motor vehicle, the electric machine having a stator winding, a rotor winding, a field regulator assigned to the rotor winding and a current converter post-connected to the stator winding having controllable switching elements, in which during a starting process of the internal combustion engine the electric machine is operated as a motor according to a rotational speed specification signal.

  • Patent number: 9821788
    Abstract: A method is described for operating a motor vehicle, in which control is applied, in the context of a drive-off operation, to an electrical machine operable in motor mode in order to deliver a torque driving the vehicle, control simultaneously being applied to a braking system of the motor vehicle in such a way that it applies a braking torque.

  • Publication number: 20150019109
    Abstract: In a method for controlling the stopping behavior of an internal combustion engine, after a stop request, an air metering device initially reduces the volume of air supplied to the internal combustion engine during the stop and subsequently increases this volume of air again at an opening crankshaft angle (KWopen), the opening crankshaft angle (KWopen) being oriented to an undercut crankshaft angle (KWlow), at which a speed (n) of the internal combustion engine when stopping drops below a predefinable speed threshold value (ns). The time characteristic of the speed (n) of the internal combustion engine after the stop request is influenced in such a way that the internal combustion engine comes to a halt in a predefinable target crankshaft angle range.
