AI Technical Summary
Technical Problem
In the prior art, touch pads or touch screens are prone to cause swaying motion and dull noise when used in motor vehicles, especially when their size is large.
Method used
By making the input unit and the actuator unit movably supported relative to the motor vehicle, and matching its resonant frequency with a spring device, the impulses cancel each other, avoiding the incoming impact of the motor vehicle, and accurately limiting the degree of movement by a support such as a roller or ball support.
Benefits of technology
The swaying movement and muffled noise in the motor vehicle are effectively avoided, ensuring that the operator can accurately operate the input unit through tactile feedback while maintaining the stability and silentness of the device.

Abstract
In a haptic operating device in a motor vehicle, in which an input unit (100, 104) can be moved by an actuator unit (200, 204) coupled to the input unit (100, 104), wherein the input unit (100, 104) has a surface, which an operator's input member (F) can touch, it is provided that the input unit (100, 104) and the actuator unit (200, 204) are supported so as to be movable relative to the motor vehicle.
