Abstract
A method for evaluating a capacity value of a capacitive sensor electrode includes an evaluation process, which includes performing a charging process of a sensor electrode, and evaluating a parameter, which depends on the capacity value of the sensor electrode. A first charging pulse duration tfor the charging process includes a first coupling duration tand a first decoupling duration twith t=t+t, of a first coupling and decoupling cycle. A second charging pulse duration t, includes a second coupling duration tand a second decoupling duration twith t=t+t, of a second coupling and decoupling cycle immediately following the first coupling and decoupling cycle. These differ from each other by a first pulse duration difference Δt.
