The control unit for a motor vehicle, and especially an automatic gearbox, has a carrier plate (5) in a housing (4) for the electronic circuits, and with an injection molded base (2). The hydraulic pressure is measured by a converter (22) through a pressure channel (6) linked to a hydraulic unit in the gearbox. A spring (11) is at the carrier plate, as part of the measurement converter, with a force transmission link (10) to a polymer membrane (13), which acts as a sealing cover for an opening (14) in the pressure channel for the spring. An expansion measurement strip (17) is at the spring, which can be measured through the deflection of the spring. |
