Description

Control system for controlling functions by means of a switch Technical Field The invention relates to a control system for controlling functions by means of a switch, in particular for operating a motor vehicle component, a motor vehicle having such a control system, and a method for controlling functions by means of the control system. Background Control systems for controlling functions, in particular for actuating motor vehicle components, are known. According to the state of the art, such control systems are, for example, motor vehicle control systems, which control functions such as, for example, windows in a motor vehicle, seat heating, exterior mirrors, radio functions, music systems, lighting control or heating control. Such control systems require that the switches controlling the respective functions close the circuit with two cables and thus control the various functions either directly or indirectly via the control device. A disadvantage of such a control system is therefore that the switch must always be connected by a cable and supplied with power. DE 102 017 114 990 B3 aims at providing a display and actuating device with a low complexity, in particular a low number of wires, and for this purpose proposes a display and actuating device, in particular a man-machine interface. The operating device has a display and a vehicle user interface with a rotation/pressing key, wherein in the case of an operation of the rotation/pressing key an acoustic signal is generated via a mechanical sound element, in particular a metal strip, according to the sound chip principle. This signal is picked up by a microphone and forwarded as a control signal for setting the vehicle function. When the rotary/push key is pressed, an acoustic signal is generated by the sound generating element and transmitted to the pickup. The sound pick-up converts the acoustic signal into an electrical output signal, which is then transmitted to an evaluation unit. The evaluation unit recognizes the electrical output signals transmitted by the sound pickup and generates control signals, for example for controlling a vehicle component or for navigating a selection menu. DE 102 022 102 374 A1 aims to provide a system for protecting a driving assistance system, so that the verification of the driving assistance system (in particular a parking assistance system) can be simplified. For this purpose, DE 102 022 102 374 A1 discloses a system comprising a sensor device which is configured to detect a user operation of a vehicle actuating element and to generate corresponding first detection data, and also to detect an acoustic signal which indicates the operation of the actuating element and to generate corresponding second detection data, and at least one evaluation module which determines a first point in time and a second point in time on the basis of the detection data. DE 102 013210 200 A1 aims to provide an operating device for a hearing aid that can be used without additional electrical sensors and additional electrical connections, is inexpensive and at the same time reliable in operation. DE 102 013210 200 A1 discloses an operating device for a hearing aid, for example a hearing aid with a mechanical operating element. When the operation element is operated, the operation noise is detected by the microphone and analyzed as an operation signal. In particular, the interior of a motor vehicle can generate a wide variety of noise. These noises can also vary depending on the speed of the motor vehicle, especially in terms of frequency and volume. Noise in the interior space of the vehicle may include engine noise, tire noise, wind noise, air conditioning system noise, road noise, occupant noise in the vehicle, electronic equipment noise, interior space component noise, or noise of the interior space carrying items of the vehicle. These noises are disturbing noises that make detection and identification of the switches proposed in the prior art difficult. Since a plurality of switches in the interior space of a motor vehicle may all employ the well-known "clapping" principle for generating acoustic signals, the acoustic identification of a particular switch and the correct allocation of its functions is also made difficult. Thus, the "clap" principle may create similar acoustic features and make explicit identification of individual switches difficult or impossible. Disclosure of Invention The object of the present invention is to provide a control system with which an improved detection of the sensor switch characteristics can be achieved compared to the prior art, wherein the control system can reliably detect the respective switch and thus reliably perform the respective predetermined function even in the event of switching noise and/or interference noise superposition. In this way, it is achieved that a plurality of switches can be operated without wiring, for example in a motor vehicle, and thus a more sustainable development of the
