A control unit has a circuit support, on which electrical and/or electronic components of an electronic circuit of the control unit are disposed. The circuit support is composed of a temperature-resistant ceramic material, and on it there is applied at least one resistive track made of a material whose electrical resistance is temperature-dependent. The resistive track is connected to an evaluation circuit that determines the temperature using resistance values measured on the resistive track. The circuit support is in thermally conductive contact with the environment that is to be taken into consideration.

Electronic control unit for a motor vehicle

A control unit has a control circuit and a pressure sensor connected to the control circuit. The pressure sensor measures the hydraulic pressure in a transmission or the induction-pipe vacuum of an engine. A common housing has a metallic base plate, into which a metallic support plate for the pressure sensor is fitted. The support plate has a borehole through which the pressure sensor is subjected to pressure. A metallic ring is secured on the support plate. A glass cylinder is secured on the support plate, and the pressure sensor, which is configured as a silicon chip, is secured on the glass cylinder.

Control unit for a motor vehicle

An electronic control unit has a housing with a base plate and a plastic hood. A circuit support is fastened to the base plate. A contact pin is fastened in the plastic hood. When the plastic hood is joined to the base plate, the contact pin is plugged through an opening in the base plate and an electric connection between the contact pin and a conductor track support is produced.
