Motor vehicle structure level controlling method, involves adjusting actual motor angle depending on actual spring strut lengths by changing motor current such that difference to desired value of engine angle lies in given tolerance range

摘要

The method involves adding an actual length of a structure spring (Laf) and geometrical dimensions of a spring strut for determining actual spring strut lengths (Lfb) corresponding to an actual distance between two fixing points. An actual motor angle is adjusted depending on the actual spring strut lengths by changing motor current in such a manner that a difference to a desired value of the engine angle lies in a given tolerance range for adjusting an axial position of a spring seat.
