OPERATING DEVICE WITH HAPTIC FEEDBACK
First Claim
1. An operating apparatus for a motor vehicle the method comprising:
- a housing;
a touchscreen, which has a display apparatus having a freely programmable display surface for representing at least one virtual operating element and a touch-sensitive position detection apparatus having a touch surface arranged in front of the display surface, wherein at least the touch surface is mounted on the housing movably relative thereto;
at least one compressive force measuring apparatus for determining a press-on force acting on the touch surface in the event of a touching actuation of the touchscreen;
at least one actuator device coupled directly or indirectly to the touch surface and serving for the targeted movement of at least the touch surface relative to the housing; and
a controller designed to determine, depending on the detected touch positions and detected press-on forces, whether a correct haptic actuation of the at least one virtual operating element is present, and, if this is the case, to initiate a function assigned to the at least one virtual operating element and to drive the at least one actuator device to generate a haptic feedback at the touch surface,wherein the controller compares the press-on forces with a first force threshold value and a second force threshold value deviating therefrom and generates a first actuator activation signal in the event of the first force threshold value being exceeded, and generates a second actuator activation signal, which is different from the first actuator activation signal, in the event of the second force threshold value subsequently being undershot,wherein the first and second actuator activation signals instigates in each case a haptic feedback at the touch surface via the actuator device, andwherein the haptically perceptible feedbacks generated by the first actuator activation signal and the second actuator activation signal at the touch surface are different, wherein the controller generates the haptic feedbacks in each case in the form of a short mechanical pulse.

Abstract
Touch-sensitive operating apparatuses having a touchscreen which generates a haptic feedback in the event of an actuation of a virtual operating element and methods for operating functions. The method includes representing a virtual operating element on a display surface, detecting touch positions on a touch surface of a touch-sensitive position detection apparatus, detecting press-on forces in the event of a touching actuation of the touch surface, evaluating the detected touch positions and press-on forces, determining whether a correct haptic actuation of the virtual operating element is present, initiating a function assigned to the at least one virtual operating element, and generating a haptic feedback at the touch surface. The operating apparatus has a haptic controller which, on the basis of the press-on forces determined, generates two different haptic feedbacks in the event of an actuation process of a virtual operating element.
