More Information
Summary:A control device (RE) for controlling a bearing element (VLE) for the bearing of an assembly, particularly an internal combustion engine, and/or a transmission, is provided in a motor vehicle. The bearing element (VLE) comprises a chamber (104) having a magnetorheological fluid, a coil (106), which creates a magnetic field in the chamber (104), and a pressure sensor (118) measuring the pressure of the fluid in the chamber (104). The control device comprises a pressure detection device (202), which detects a measuring value of the pressure measured by means of the pressure sensor (118) in cycles, a calculating device (204), which calculates a changed speed of the pressure by using at least two measurement values, and a switch unit (208), which switches on a control current by means of the coil (106) depending on whether the changed speed exceeds a threshold value.
