Abrégé
(EN)
A plane capacitive sensor includes a plane capacitor (1), a plane capacitor compensator (2) for eliminating disturbing signals, and a sensor detection circuit. The sensor adopts two plane capacitors, and one capacitor serves as a detecting capacitor, and another serves as a compensating capacitor. The fixing position and the shape of the compensating capacitor are changeable so as to make the capacitor become insensitive to the rain on the outside surface of windscreen, but sensitive to temperature shift and electromagnetic disturbance. When suffered temperature shift or electromagnetic disturbance, the measurements of the detecting capacitor and the compensating capacitor are varied simultaneously and their variation magnitudes are equal with each other approximatively. When suffered variation of the rain, the measurement of the detecting capacitor is varied and the measurement of the compensating capacitor keeps constant substantially.

L'invention concerne un capteur capacitif plan comprenant un condensateur plan (1), un compensateur (2) de condensateur plan destiné à éliminer les signaux perturbateurs et un circuit de détection du capteur. Le capteur englobe deux condensateurs plans et un condensateur sert de condensateur de détection, l'autre servant de condensateur de compensation. La position de montage et la forme du condensateur de compensation peuvent être modifiées de façon à rendre le condensateur insensible à la pluie sur la surface extérieure du pare-brise, mais sensible à une dérive de température et à une perturbation électromagnétique. Lorsqu'ils sont soumis à une dérive de température ou à une perturbation électromagnétique, les mesures du condensateur de détection et du condensateur de compensation varient simultanément et leurs amplitudes de variation sont approximativement égales entre elles. Lorsqu'ils sont soumis à une variation de pluviométrie, la mesure du condensateur de détection varie et la mesure du condensateur de compensation reste sensiblement constante.
