1. A method for driving dynamic regulation of a road vehicle in which reference values for at least a yaw rate {dot over (Ψ

  • )} and a float angle β

    of the vehicle are generated, under clock control in sequential cycles of a presettable duration TK, by a simulation computer in an electronic control unit which automatically regulates driving dynamics of the vehicle based on a model that represents the vehicle in terms of design and load state parameters thereof, and based on operating data which includes measured current values of steering angle δ and

    vehicle speed vx, said simulation computer generating control signals for activating at least one wheel brake of the vehicle based on a comparison of a reference value {dot over (Ψ

    )}SO as a setpoint for the yaw rate of the vehicle and actual values {dot over (Ψ

    )}I of the yaw rate of the vehicle that are continuously recorded a yaw rate sensor device, or for reducing an engine drive torque of the vehicle;

    whereinthe vehicle model is implemented by a linear differential equation system of the form
