Abstract: In a method for operating a motor vehicle, an actuation speed of a power input element, e.g., an accelerator pedal, is detected and evaluated, and a drag torque is influenced as a function of the detected actuation variable. At least one measure which influences the drag torque is carried out if the following conditions are all satisfied: (i) an actuation speed is less than a limiting value, (ii) a position of the input element is greater than zero, and (iii) the power input element is actuated in the direction of a power reduction.

Abstract: The invention concerns a method and a device for determining parameters of a transmission link (2) which is connected to a transmission/reception device (1A; 1B) on the basis of an echo signal of a transmission signal which is transmitted onto the transmission link (2) with at least one individual pulse. The echo signal is first captured. The echo components of the echo signal are shortened by applying a preferably adjustable shortening filter (19) to the captured echo signal. The invention also proposes applying an adjustable further filter (18) to the echo signal, and adjusting the adjustable further filter (18) and preferably also the shortening filter (19) to select an effective central frequency of the at least one individual pulse. The parameters of the transmission link (2) are determined by evaluating the filtered echo signal on the basis of the temporal position and/or amplitude of at least the echo component from the end of the transmission link (2).
