Driving dynamic control or regulating system and method for a two-track, two-axle motor vehicle

Abstract

A system and method are provided for controlling or automatically controlling the driving dynamics of a two-track, two-axle motor vehicle having only one driven axle, which, for the rolling moment support, has a system for changing the distribution of the wheel contact forces to the left and right wheel respectively of each axle. The fractions of the rolling moment support taken over by the front axle and by the rear axle are changeable as a function of the drive torque provided by the drive assembly of the motor vehicle. For this purpose, a desired wheel contact force for the driven wheels can be determined from the drive torque, and by way of this desired wheel contact force, the distribution of the rolling torque support can be determined. A change of the distribution of the rolling moment support as a function of the drive torque of the drive assembly is preferably carried out only if the otherwise available contact force would otherwise not be sufficient for the transmission of the drive torque to the road. A slip control may be superimposed on this pilot control, which slip control seeks to minimize the deviation between the determined rotational speed difference of the driven wheels and the rotational speed difference corresponding to the respective driving condition.
