Arrangement for a vehicle for detecting an activation action for activating a function on the vehicle

A method for detecting an activation action for the activation of a function on a vehicle,

• wherein the following steps are carried out:
• carrying out a sensing of a change by a sensor element in a vicinity of the sensor element,
• controlling the sensor element by a controlling arrangement to provide a sensing signal whose frequencies comprise at least one predefined sensing frequency,
• carrying out a determination of at least one parameter specific to the sensing of the sensor element for the detection of the activation action by means of an evaluation arrangement, wherein the evaluation arrangement is interconnected to the sensor element via a signal path in order to carry out the determination repeatedly on the basis of the sensing signal,
• carrying out at least one reduction of the frequencies of the sensing signal lower than the at least one sensing frequency by a filter arrangement in the signal path, which comprises at least one high-pass, and
• providing the sensing signal to the filter arrangement depending on a variable sensor capacitance of the sensor element by means of an electric voltage follower of a transmission arrangement, wherein the transmission arrangement is provided in the signal path between the sensor element and the filter arrangement.
