To achieve this motion profile, a force excitation adapted to the resonance frequencies of the system is required, which in principle typically looks like in the diagram of FIG. 2. The distance between the two maxima must be exactly adapted to the frequency of the oscillation to be suppressed. Otherwise, this oscillation will occur in the form of post-oscillations after the actual pulse (see the dashed line in the diagram of FIG. 1). This post-oscillation noticeably reduces the quality of the haptic feedback and must therefore be avoided.

It is known to try to bring the oscillating haptic feedback system to a standstill by controlling the drive (actuator) in the form of a pulse at a certain point in time (see e.g. DE-A-10 2013 007 962, DE-A-10 2014 019 162, DE-B-10 2007 058 110 and EP-A-2 348 384).

An object of the invention is to provide an operating unit with substantially oscillation-free haptic feedback.

This object is achieved with the invention proposing an operating unit for a vehicle, provided with

• • a housing,
  • an operating element elastically mounted in and/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, and
  • a control unit for controlling the actuator when manually actuating the operating element,
