  • Method for determining a time of contact on a capacitive sensor element
    Patent number: 11175774
    Abstract: A method for determining a time of contact of a capacitive sensor includes continuously measuring a capacitance value of the capacitive sensor and processing the measured capacitance value into a digital sensor signal. The sensor signal is filtered to output a filter signal. Initial dynamics of the filter signal are identified upon the filter signal exceeding a first set filter threshold value. A time at which the filter signal falls below a second set filter threshold value is determined as being a potential time of contact of the capacitive sensor. An actual time of contact of the capacitive sensor is determined when the sensor signal relative to an offset of the sensor signal exceeds a sensor signal threshold value. The offset of the sensor signal is a value of the sensor signal prior to the contact of the capacitive sensor.
