Abstract: An illustrative example method of operating a capacitive vehicle entry control device includes: determining a plurality of capacitance values of the vehicle entry control device during a measurement period; determining an average capacitance of the plurality of capacitance values; determining whether the determined average capacitance exceeds an average threshold; determining a range of the plurality of capacitance values; determining whether the determined range exceeds a range threshold; and initiating a vehicle entry process when the determined average capacitance exceeds the average threshold or when the determined range exceeds the range threshold.
