Control device in a motor vehicle and a method of attaching a pressure sensor used by the control device

摘要

The control device has a control circuit and a pressure sensor for measuring the hydraulic pressure in the gearbox. The control circuit and the pressure sensor are accommodated in a common housing. The housing has a metallic baseplate which is connected in a pressure tight fashion to a hydraulic unit of the gearbox and is provided with a bore hole through which pressure is applied to the pressure sensor. A carrier for the pressure sensor has a cylinder-like projection which is pressed into the bore hole in such a way that a pressure tight and frictionally locking connection is produced between the carrier and the baseplate as a result of the displacement of material. The pressure sensor can also be used to measure the intake vacuum of an engine.
