Abstract
A control device of a motor vehicle, which control device receives, from at least one body-side sensor, a vibration actual value of at least one corresponding body-side reference point and receives, from at least one chassis-side sensor, a vibration actual value of at least one corresponding chassis-side reference point, the control device making a decision on the reference point or points for which actuating signals for the actuators of the active assembly bearings are generated, and on which vibration desired value is used, in such a manner that the respective vibration actual value follows the respective vibration desired value.
Claims11
A control device of a motor vehicle, the control device being configured to:
- receive actual values of controlled variables from sensors, including, from at least one body-side sensor, a vibration actual value of at least one corresponding body-side reference point and, from at least one chassis-side sensor, a vibration actual value of at least one corresponding chassis-side reference point, the actual values including at least one of a vibration actual value of an axle from a chassis-side axle sensor or a vibration actual value of a steering system from a chassis-side steering system sensor;
- generate actuating signals for actuators of active assembly bearings on the basis of a control deviation between the actual values and corresponding desired values so as to cause the actual values to follow desired values;
- and
- determine each reference point for which actuating signals for the actuators of the active assembly bearings are generated, and determine the respective vibration desired value that is used.
