Method for controlling the level of an air-suspended motor vehicle

2:

• The method as claimed in claim 1, further comprising for the air spring bellows for which the tolerance band has been expanded, adjusting, if corrected upper tolerance limit or the corrected lower tolerance limit is exceeded, the actual level to a value which is within the corrected tolerance band and outside the uncorrected tolerance band.

3:

• The method as claimed in claim 1, further comprising for the air spring bellows for which the tolerance band has been expanded, adjusting, if corrected upper tolerance limit or the corrected lower tolerance limit is exceeded, the actual level to a value which is within the uncorrected tolerance band.

4:

• The method as claimed in claim 1, wherein the method is used in operating a bus having at least one vehicle door.

5:

• The method as claimed in claim 4, wherein when the vehicle door is open, the tolerance band (ΔxT) for an air spring bellows which is closest to the vehicle door is not assigned corrected tolerance limits even though its actual level value is outside the limits of the uncorrected tolerance band, but instead the tolerance band for an air spring bellows arranged on the same vehicle axle on the opposite vehicle side is assigned corrected tolerance limits.

6:

• The method as claimed in claim 4, wherein when the vehicle door is open, the tolerance band for an air spring bellows which is closest to the vehicle door is not assigned corrected tolerance limits even though its actual level value is outside the limits of the uncorrected tolerance band, but instead the tolerance band for an air spring bellows arranged on the other vehicle axle on the opposite vehicle side, i.e. diagonally opposite, is assigned corrected tolerance limits.

7:

• The method as claimed in claim 4, wherein when the vehicle door is open, the tolerance band for an air spring bellows which is closest to the vehicle door is not assigned corrected tolerance limits even though its actual level value is outside the limits of the uncorrected tolerance band, but instead tolerance bands for all the air spring bellows which are arranged on the opposite vehicle side of the vehicle are assigned corrected tolerance limits.

8:

• The method as claimed in claim 4, wherein the relevant upper and/or lower corrected tolerance limits for the air spring bellows arranged closest to the vehicle door are reset to the upper and/or lower uncorrected tolerance limits.

9:

• The method as claimed in claim 8, resetting to the upper and/or lower uncorrected tolerance limits for the air spring bellows arranged closest to the vehicle door is performed before control of the level takes place.

10:

• The method as claimed in claim 5, wherein the relevant tolerance limits for the air spring bellows arranged at the front axle are only correspondingly modified if the front entry door of the motor vehicle is also actually open.

11:

• The method as claimed in claim 1, wherein an air spring bellows, the actual level of which exceeds the upper or lower uncorrected tolerance limit, is assigned the same upper and/or lower corrected tolerance limits as every other one of the air spring bellows of the vehicle if the upper and/or lower uncorrected tolerance limits on one of these other air spring bellows are exceeded.

12:

• The method as claimed in claim 1, wherein an air spring bellows, the actual level of which exceeds the upper or lower uncorrected tolerance limit, is assigned different upper and/or lower corrected tolerance limits than one or all of the other air spring bellows of the vehicle if the upper and/or lower uncorrected tolerance limits on one of these other air spring bellows are exceeded.

13:

• The method as claimed in claim 1, wherein the upper and the lower tolerance limit on an air spring bellows, from the exceeding of which this air spring bellows is assigned corrected upper and/or lower tolerance limits, is the same for all the air spring bellows.

14:

• The method as claimed in claim 1, wherein the upper and the lower uncorrected tolerance limit on an air spring bellows, from the exceeding of which this air spring bellows is assigned corrected upper and/or lower tolerance limits, is different for all or some of the air spring bellows.

15:

• The method as claimed in claim 1, wherein the value of the positive or negative deviation of the actual level from the setpoint level, from which the associated air spring bellows is assigned a corrected upper and/or lower tolerance limit, is within the value range of the uncorrected tolerance limits.
