Abstract: A method for operating an electromechanical drum brake including at least two brake shoes of a motor vehicle. In the method, a static force-path characteristic curve of the brake shoes for increasing and decreasing the braking force is ascertained as a hysteresis curve when the motor vehicle is at a standstill; at least one stiffness and one friction value of at least one of the brake shoes are ascertained as parameters as a function of a course of the static force-path characteristic curve; as a function of the ascertained parameters, a dynamic force-path characteristic curve is ascertained using a physical substitute model of the drum brake, and for satisfying a braking request, the drum brake is controlled as a function of the dynamic force-path characteristic curve.

Abstract: A method for ascertaining a motor constant of an electric machine, in particular an actuator assembly. At least one excitation signal having at least one direct current component and one alternating current component is specified. The machine is controlled using the excitation signal. At least one actual value of a motor current of the machine and one actual value of a rotation rate of a rotor shaft of the machine are ascertained in each case. The motor constant is ascertained as a function of the excitation signal and the actual values.

Abstract: A method for determining an absolute position for an ego vehicle. The method includes a step of determining an other vehicle position of another vehicle and a piece of vehicle information of the other vehicle by using a vehicle signal that represents a vehicle-to-vehicle message of the other vehicle. The method furthermore comprises a step of determining a piece of vehicle information of the other vehicle and a relative position between the ego vehicle and the other vehicle by using a data signal provided by the other vehicle and a step of ascertaining the absolute position of the ego vehicle by using the other vehicle position and the relative position.

Abstract: A method for the automated selection of data sets for a method for machine learning for detecting operating variables of a motor vehicle, in which methods, measuring signal sequences for particular operating variable ranges of the motor vehicle, are detected during the operation of the motor vehicle. In the method, the operating variable ranges are assigned memory areas, each including multiple slots, each of which is configured to store a data set containing a detected measuring signal sequence, and data sets already stored in the slots being overwritable with data sets newly detected instantaneously for the same memory area in each case. For each slot of a memory area in which a data set is stored, an estimated slot error value is formed and stored together with the measuring signal sequence. The data sets, whose estimated slot error value is comparatively low, are preferably overwritten.
