Claim 0:
1. An operating unit for a vehicle, comprising:
a housing,
an operating element elastically mounted in or on the housing,
wherein the elastically mounted operating element forms a spring-mass system having a construction-related resonance frequency,
an actuator for pulse-shaped mechanical excitation of the operating element, the actuator operable to be controlled
when manually actuating the operating element,
wherein the resonance frequency is, due to construction, above the highest cut-off frequency that can typically still be detected by receptors for haptic feedback and/or for tactile sensation of a person, and
wherein the frequency spectrum of the mechanical pulse at the resonance frequency excited by the actuator has no frequency components in that the power density spectrum of the mechanical pulse above the cut-off frequency is energy-free or substantially energy-free.
