Abstract (en)
[origin: WO2014016097A1] In a method for detecting and processing measurement values of at least one capacitive proximity sensor which is arranged in the rear region of a motor vehicle close to the ground and for initiating an operating function of a tailgate by a prespecified foot movement of an operator, a measurement value of the proximity sensor is periodically detected after in each case one scanning interval, and a digital measurement value which corresponds to the measurement value is stored in a FIFO memory. In a first, energy-saving evaluation mode, a filter value is calculated from the currently stored digital measurement value and a prespecified second number of previously stored digital measurement values, in each case after a prespecified first number of digital measurement values are stored, by each of said stored digital measurement values being multiplied by an associated first factor in each case and the results being added, the filter value being compared with the threshold value and a second evaluation mode being activated when the filter value exceeds the threshold value. In the second, normal evaluation mode, a filter value is calculated from the currently stored digital measurement value and a prespecified fourth number of previously stored digital measurement values, in each case after a prespecified third number of digital measurement values, which third number is smaller than the first number, are stored, by each of said digital measurement values being multiplied by an associated second factor in each case and the results being added, and the filter value being fed to an algorithm for identifying a signal profile which corresponds to the prespecified foot movement.
