Method and device for discriminating capacitive detection, and equipment provided with such a device.

摘要

The invention relates to a method for capacitive detection of surrounding objects (102,104) which may be in the environment of an item of equipment provided with a capacitive detection device (100) comprising a step of detection, called discriminant, comprising the operations following: polarization of a first surrounding object (102) at a first alternating potential (V1), different from a ground potential (M) and from the potential of at least one second surrounding object (104), at a first frequency (F1); and determining a first discriminating signal representative of a capacitance, said electrode-object capacitance, seen by said at least one measuring electrode, at said first frequency (F1).
