PROBLEM TO BE SOLVED: To provide a method for controlling a driving state of an automobile. SOLUTION: A method of controlling the handling of a vehicle is provided, and the method calls for at least the vehicle weight (G) and the instantaneous location of the center of gravity (SP) to be determined from tire-sensor signals. In a further embodiment, the invention calls for the use of a weight-distribution model which includes as its basic data the basic weight distribution of the vehicle, i.e. weights which are always the same, even at different loads. In addition, variable weights, such as those of the passengers, the luggage, etc., and their location are determined by means of the tire-sensor signals and incorporated in the weight-distribution model as a variable weight distribution. Knowing all such data, parameters characteristic of the dynamics of the vehicle's motion can be determined, thus enabling vehicle yaw rate and slip angle to be determined by suitable calculations without being dependent on the signals from a yaw-rate sensor or a lateral-acceleration sensor.
