are shown on the surface of roadway 8 and provided with reference numerals 13 getting back to fig1 motor vehicle 1 is shown there inclined traveling in curve 7 so that there exists an angle u03c6 between a vertical axis and a vertical vehicle axis 14 through motor vehicle 1 angle u03b4 is normally less than 50 u00b0 60 u00b0 as a rule 56 u00b0 it is true that the exemplary embodiment according to fig1 shows a horizontal roadway surface of roadway 8 but it is possible that the curve is banked and consequently it is not the angle to the roadway surface that remains relevant but rather the angle to the horizontal as may be easily seen in fig3 one of inclination sensors 10 measures length l the pitch sensors determine the height recalculated to height h 0 via an appropriate algorithm furthermore in a computing device 15 which is not shown in the figures up to 4 an angle u03b8 k is ascertained in computing device 15 angle u03c6 is determined using a subsequent algorithm in this way the inclination angle is determined with the aid of measured length l that is the distance between one of inclination sensors 10 and the surface of roadway 8 the example being shown being that a right antenna lobe 12 as seen in the direction of travel forms the basis however left antenna lobe 12 as seen in the direction of travel may also form the basis since it is also an aim of the present invention to have available the knowledge of the contact pressure and the contact conditions in every driving situation that is also during braking processes that cause u201c pitching u201d and in curves the effect of braking while causing u201c pitching u201d is shown in fig4.
