Abstract
The invention relates to a method for determining quantities which characterize driving behavior. Signals indicative of steering angle, longitudinal speed of the vehicle, and two transverse accelerations located one behind the other in the longitudinal direction of the vehicle, are fed to a computing device. The measured quantities are used to derive further quantities in the computing device using vehicle-specific quantities and a vehicle model. Furthermore, at least one of the further quantities is the sideslip angle or the yaw-angle velocity which are determined and output by the computing device.

Method for determining at least one quantity which characterizes driving behavior, using a computing device which is fed signals representing measured quantities of the steering angle, of the longitudinal speed of a vehicle that has tires and of two transverse accelerations located one behind the other in the longitudinal direction of the vehicle, comprising the steps of:
- deriving further quantities using vehicle-specific quantities and a vehicle model;
- determining yaw-angle velocity using the measured quantities and the derived further quantities along with the vehicle model, wherein the vehicle model takes into account the transverse force buildup at the tires of the vehicle;
- outputting the yaw-angle velocity to a vehicle control device;
- and
- influencing driving behavior of the vehicle with the vehicle control device as a function of the yaw-angle velocity.
