Abstract:
The invention relates to an arrangement (10) for a capacitive sensor device (20) of a vehicle (1), in particular for control and/or evaluation at the capacitive sensor device (20) for detecting an activating action at the vehicle (1), comprising
at least one sensor electrode (20.1) for sensing a change in a vicinity of the vehicle (1),
a transmission arrangement (30) for a frequency- and/or phase-dependent transmission of an electrical input signal (E) and an output of an output signal (A),
an output (30.2) of the transmission arrangement (30), which is electrically connected to the sensor electrode (20.1) to output the output signal (A) at the sensor electrode (20.1) for performing the sensing,
wherein the transmission arrangement (30) comprises a controlled source device (30.3) to output the output signal (A) as a guided electrical signal at the sensor electrode (20.1) depending on the frequency- and/or phase-dependent transmission of the input signal (E).
at least one sensor electrode (20.1) for sensing a change in a vicinity of the vehicle (1),
