Abstract
The invention relates to an operator control apparatus for outputting haptic feedback comprising an operator control surface, an actuator, which is at least indirectly coupled to the operator control surface, for generating the haptic feedback on the operator control surface and a control unit which is designed to drive the actuator by means of a haptic component of a control signal for generating the haptic feedback. In this case, the control unit is designed to drive the actuator by means of an acoustic component of the control signal for generating acoustic feedback.
Claims13
An operator control apparatus for outputting a feedback, comprising:
- an operator control surface;
- an actuator at least indirectly coupled to the operator control surface, which is configured as a DC voltage unbalance actuator, for generating a haptic feedback on the operator control surface;
- a control unit, which is configured to control the actuator using a haptic component of a control signal for generating the haptic feedback;
- wherein the control unit is configured to drive the actuator using an acoustic component of the control signal for generating an acoustic feedback;
- and
- the haptic component is a DC voltage component of the control signal and the acoustic component is an AC voltage component of the control signal.
A method for operating an operator control apparatus, comprising
- generating, by a control unit, a control signal including a haptic component;
- driving, using the control signal, an actuator, which is at least indirectly coupled to an operator control surface, and which is configured as a DC voltage unbalance actuator;
- generating a haptic feedback on the operator control surface by the actuator according to the haptic component of the control signal;
- wherein the control signal including an acoustic component is generated by the control unit;
- an acoustic feedback is generated by the actuator according to the acoustic component of the control signal;
- and
- the haptic component is a DC voltage component of the control signal and the acoustic component is an AC voltage component of the control signal.
