摘要： A capacitive distance sensor includes a sensor element having an electrically conductive, elongated, flat sensor area which in turn contains a number of holes. The sensor area is completely surrounded by an electrically non-conductive insulating body, with the result that the insulating body completely covers the edge regions of the holes. The sensor element is produced, in particular, by first of all making the holes in the sensor area. In a subsequent step, the sensor area is completely encased by the insulating body which also completely fills the holes in the sensor area.

摘要： An electronic control device for use in a motor vehicle includes an electronic housing for accommodating an electronics system that includes a circuit board, and a resistance sensor for detecting water that has penetrated into the electronic housing. The resistance sensor includes at least two sensor electrodes, each of which is present, at least in one section, in an uninsulated state with respect to the interior of the electronic housing, and a control unit that is configured to detect and evaluate a measured resistance value between the two sensor electrodes. The control unit is further configured to output a trigger signal when the detected measured resistance value or its deviation from a normal value meets a trigger criterion that is characteristic of a contact closure between the two sensor electrodes that is caused by the presence of water in the electronic housing.

摘要： An electronic control device for use in a motor vehicle including an electronic housing, a capacitor sensor, and a control unit. The capacitor sensor may be provided with a capacitor sensor electrode arranged inside the electronic housing. The control unit may be configured to output a trigger signal in response to receiving a measured capacitance value deviating from a threshold value, from the capacitor sensor electrode, indicative of a conductive liquid in the electronic housing.
