Abstract
A method for controlling the driving stability of a vehicle comprising the steps of determining whether or not a curved path lies before the vehicle, if a curved driving path found to exist; determining the probable uncorrected “inherent” path (B), determining the specified “set” path (S), a comparison of the inherent path (B) and the set path (S) and determination of a deviation (x) in the controlled path taken; determining the distribution of a roll moment (ERCk) for at least a partial compensation of the deviation (x) from the path; realization of the determined roll moment distribution (ERCk) by the issuing of position signals (SMVA, SMHA) to a forward active stabilizer (2) for the changing of a forward support moment (MVA).

10. A method for controlling a driving stability of a vehicle comprising at least the following steps:
-
determining whether or not curved driving is present before the vehicle, and if a curved driving path is being approached by the vehicle then;
determining a probable inherent path of the vehicle (B);
determining a preferred and controllable set path (S);
comparing the inherent path (B) and the set path (S);
determining a deviation (x) in the controlled path taken;
determining apportionment of a roll moment apportionment (ERCk) for at least a partial compensation of the deviation (x);
actuating the determined roll moment apportionment (ERCk) by issuing position signals (SMVA, SMHA) to a forward active stabilizer (2) for changing of one of a forward support moment (MVA) and a rear active stabilizer (3) for changing of a rear support moment (MHA); and
determining a travel radius which is too small for the inherent path (B) as compared to the set path (S), the forward support moment (MVA), relative to the rear support moment (MHA) becomes larger, and upon the determination of a path radius of the inherent path (B) as being too large, compared to the set path (S), the forward support moment (MVA) relative to the rear support moment (MHA) is increased to a lesser degree. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
