    Abstract: A device for detecting a driver demand, the device outputting a purely electronic actuating signal, includes an actuating surface, for a foot of a user, the actuating surface being displaceable in an actuation direction in order to generate the actuating signal. At least two compression bodies arranged one behind the other in the actuation direction are provided, each of which has one elastic element and one rigid element, which are arranged one behind the other in the actuation direction in such a way that one rigid element acts on one elastic element when the actuating surface is acted upon by an actuation force. In addition, a sensor system is provided, the signal of which permits an inference to be made regarding the displacement of the actuating surface and is usable for generating the actuating signal.
