Control device and method for activating an active haptics operator control element for a motor vehicle

1 . A device for activating an active haptics operator control element for a motor vehicle, comprising:

a control device operatively configured to:

determine whether the operator control element is being operated with a short press or a long press;

when it has been determined that the operator control element has been operated with a short press, to:

determine whether the operator control element has an assigned long-press function that is performable after the operator control element has been operated with a long press; and

activate the operator control element to output a first of two or more active haptic feedback signals when it has been determined that the operator control element has an assigned long-press function; and

activate the operator control element to output a second of the two or more active haptic feedback signals when it has been determined that the operator control element has no assigned long-press function.

2 . The device according to claim 1 , wherein:

the second of the two or more active haptic feedback signals comprises an active haptic short-press feedback,

the active haptic feedback and the active haptic short-press feedback being different than one another.

3 . The device according to claim 1 , wherein the control device is further configured to:

activate the operator control element to output no active haptic feedback or an active haptic long-press feedback when it has been determined that the operator control element has been operated with a long press,

the active haptic feedback and the active haptic long-press feedback being different than one another.

4 . The device according to claim 1 , wherein the operator control element is operable in a first switching position and in a second switching position, the control device being further configured to:

distinguish whether the operator control element is being operated in the first switching position or in the second switching position when it has been determined that the operator control element has been operated with a short press or a long press, and

activate the operator control element to output the active haptic feedback such that a first active haptic feedback is output when the operator control element is operated in the first switching position and a second active haptic feedback is output when the operator control element is operated in the second switching position.

5 . The device according to claim 4 , wherein

the operator control element is operated in the first switching position as a result of a first switching threshold being exceeded and the operator control element is operated in the second switching position as a result of a second switching threshold being exceeded,

the second switching threshold is exceeded in the event of an operating movement that is in the same direction as and has a greater emphasis than an operating movement to exceed the first switching threshold.

6 . The device according to claim 5 , wherein the greater emphasis of the operating movement comprises a greater operating force.

7 . The device according to claim 4 , wherein the control device is further configured to:

determine that the operator control element is being operated in the first switching position when the first switching threshold is exceeded after a first return threshold has been exceeded; and

determine that the operator control element is being operated in the second switching position when the second switching threshold has been exceeded after a second return threshold has been exceeded, and

the first return threshold is designed to be below the second return threshold and the second return threshold is designed to be below the first switching threshold.

8 . An active haptics operator control unit for a motor vehicle, comprising:

the device according to claim 1 ; and

the active haptics operator control element.

9 . A motor vehicle comprising an active haptics operator control unit according to claim 8 .

10 . A method for activating an active haptics operator control element for a motor vehicle, the method comprising:

determining whether the operator control element is being operated with a short press or a long press;

when it has been determined that the operator control element has been operated with a short press, then:

determining whether the operator control element has an assigned long-press function that is performable after the operator control element has been operated with a long press;

activating the operator control element to output a first of two or more active haptic feedback signals when it has been determined that the operator control element has an assigned long-press function; and

activating the operator control element to output a second of the two or more active haptic feedback signals when it has been determined that the operator control element has no assigned long-press function.
