  • Publication number: 20200340708
    Abstract: A PTC heating element has a casing that joins as a unit at least one PTC element, conductor paths electrically connected to the PTC element, and insulating layers bearing, in a heat-conductive manner against the PTC element. The PTC heating element also has contact strips which project over itself and which are electrically conductively connected to the conductor paths for energizing the PTC element with different polarities. The casing forms a receptacle space that receives the PTC element, the conductor paths, and the insulating layers. In order to improve heat decoupling from the PTC element, the receptacle, in a cross-sectional view, is defined by two oppositely disposed inner surfaces covering the PTC element and concave cavities, adjoining the inner surfaces and forming the longitudinal edges of the casing, the diameter of which is greater than the distance between the inner surfaces. The electric heating device has at least one PTC heating element arranged in a circulation chamber.

  • Publication number: 20200300684
    Abstract: A sensor device for detecting liquid, in particular in a controller of a steering system of a vehicle, includes at least one sensor element and a testing unit. The sensor element is electrically connected to the testing unit. The testing unit has a signal transmitter, connected to the sensor element, that is configured to generate an electrical test signal, and a signal receiver, connected to the sensor element, that is configured to detect a reaction signal for the electrical test signal. The signal transmitter and the signal receiver are each connected at high impedance to the at least one sensor element. The testing unit is configured to detect the reaction signal at least at a time as a first reaction signal for which the electrical test signal has been generated in order to infer a presence of the medium.

  • Publication number: 20200295916
    Abstract: A method corrects at least one transmission parameter for data transmission between a sensor unit and a control unit. A sensor timing signal is generated by a sensor oscillator with a predetermined period. The at least one transmission parameter is determined on the basis of the sensor timing signal. A reference timing signal is generated by a reference oscillator with a predefined reference period. The sensor timing signal is compared with the reference timing signal. A deviation of a current period of the sensor timing signal from a reference period is determined on the basis of the comparison. The at least one transmission parameter is corrected on the basis of the determined deviation.

  • Publication number: 20200264012
    Abstract: A method monitors a sensor clock signal in a sensor unit, which is generated and output for a data transfer between the sensor unit and a control unit with a predefined period duration. A reference clock signal having a predefined reference period duration is received. The sensor clock signal is compared to the reference clock signal. Based on the comparison, a deviation of the current period duration of the sensor clock signal from a target period duration is detected. Based on the detected deviation, a counting pulse or a reset pulse is emitted.

  • Publication number: 20200171920
    Abstract: An electric heating device, in particular for a motor vehicle, includes a housing which has an inlet and outlet opening for a medium to be heated and which encloses a layered structure. The layered stricture comprises at least one PTC element which is electrically conductively connected to conducting elements leading to connections of different polarity, and heat-emitting elements that are conductively connected on both sides to the PTC element. In order to provide improved heat dissipation, the heat-emitting elements include a panel element that is provided with perforations and that is made of a heat-conducting material.

  • Patent number: 10584732
    Abstract: A connecting expansion bolt over-molded with an expansion sleeve includes a bolt head at one bolt end and a bolt cone tapering in the direction of the bolt head. At the other bolt end, the bolt cone and an adjoining bolt shaft portion are over-molded with a plastic expansion sleeve, the sleeve end of which that surrounds the bolt cone is divided into a plurality of spreadable sleeve segments by open-ended slits. Provision is made for the sleeve end that surrounds the bolt cone to be divided into at least three sleeve segments. For at least two of the slits on the bolt cone that separate the sleeve segments from one another do not extend parallel to the bolt axis.

  • Patent number: 10485059
    Abstract: A PTC heating element includes at least one PTC element provided between strip conductors. To reduce the air gap and creep distance between the two strip conductors an insulating mass seals at least one of the strip conductors and/or the PTC element over the whole circumference. In the electric heating device according to the invention, such a PTC heating element lies in an electrically conducting manner against heat-emitting surfaces of the heating device. According to the method of the invention for producing an electric heating device, the strip conductors are glued to the PTC element for producing a PTC heating cell. The PTC heating cell is then sealed between two electrical insulation layers by an insulating mass which is applied circumferentially around at least one of the strip conductors and/or the PTC element.
