Abstract
A method for detecting presence close to a sensor installed in a motor vehicle, the method including: a plurality of steps of conversion, at a plurality of different values of the reference voltage, of an analog voltage signal into a plurality of different coded digital values; correlating the coded digital values in order to obtain a correlation value; comparing the obtained correlation value with a predetermined reference value; detecting human presence close to the sensor when the difference between the obtained correlation value and the predetermined reference value is greater than a predetermined detection threshold.
