1. A vehicle arrangement for a capacitive sensor device comprising:
a control device designed as input signal source and configured for providing a digital input signal by digital signal generation,
a control arrangement electrically connected to the control device and configured to provide an electrical input signal based on the digital input signal; wherein the control arrangement comprises a digital-analog-converter configured for converting the digital input signal provided to the control arrangement by the control device; and
a transmission arrangement for providing an output signal based on the electrical input signal;
wherein the control arrangement is connected to an input of the transmission arrangement and transmits the electrical input signal to the transmission arrangement,
wherein the electrical input signal is received by the transmission arrangement and undergoes a frequency dependent change within the transmission arrangement to form the output signal, wherein the transmission arrangement is designed as a filter configured for filtering the electrical input signal, and
wherein the output signal is provided from the transmission arrangement to a sensor element of the capacitive sensor device,
wherein the sensor element is operated based on the output signal, wherein the sensor element detects changes in the vicinity of the sensor element,
wherein the control arrangement is at least connected to a control device or is integrated therein in order to be controlled by the control device for forming the input signal.
