Capacitive sensor for use in collision protecting device of vehicle for detecting object, particularly for detecting snagging or collision at mobile vehicle part, has capacitance measuring unit interconnected with electrode

摘要

The capacitive sensor has an electrode arrangement (25) provided with an electrode (30,31). A capacitance measuring unit is interconnected with the electrode for determining a measured capacitance value (M). A capacitance measuring element (44) is provided to output the measured capacitance value as analog signal. An analog phase (47) is provided downstream to the capacitance measuring element for subtraction of an offset-value (O) from the measured capacitance value.
