Abstract:
A method of determining the nominal driving behavior of a two-axle vehicle during control of the two-axle vehicle in a curve, comprising the steps of:monitoring slip angle,if slip angle increases, continually reducing slip rigidity values C.sub.L only of the wheels of the front axle so that the slope of the lateral-force/side-slip-angle characteristic assumes a smaller value C.sub.NL wherein, once the lateral-force/side-slip-angle characteristic approaches a peak value, reducing the slip rigidity values with a growing slip angle continually such that the slope of the lateral-force/side-slip-angle characteristic is approximately zero, wherein the reduction toward a reduced slope and toward a zero slope of the lateral-force/side-slip-angle characteristic is effected once a first and a second predetermined threshold value, respectively, of a variable correlating with the slip angle is exceeded, wherein the predetermined threshold values are dependent on a calculated road friction coefficient, which is the greater the higher the road friction coefficient is, wherein the first threshold value for reduction of the slip rigidities C.sub.L toward the smaller value C.sub.NL of the slope is a predetermined slip angle .alpha..sub.1/.mu. and directly proportional to the road friction coefficient .mu..
