<p>The invention relates to a Method to control a steering apparatus comprising following steps:
(A) Checking at every time whether there is a straight run state of the vehicle or not;
(B) If the straight run state of vehicle is reached, determines the instantaneous rack position (R) and calculates a new offset as to a difference between the instantaneous rack position (R) and the first position (R0) of said rack (7);
(C) Checking in a first justify operation, whether the new offset of the rack position in the straight run state of vehicle to the first rack position differs to an old offset, which where determined as the new offset at an earlier time, and set in this case the first justify result as to true and otherwise as to false;
(D) Checking in a second justify operation, whether the pull situation value exceeds a threshold value and set in this case the second justify result as to true and otherwise as to false;
(E) If the first and second justify results are true, set a suspension device status as to a "suspension damaged" status;
(F) If the first justify result is true and the second justify result is false, set a belt jump status as to a "belt jumped" status.</p> |
