Abstract

In a method for determining vehicle status quantities on the basis of the forces acting on the individual wheel and detected by means of tire sensors, where the measured quantities represent the longitudinal and lateral tire forces as well as the vertical tire forces, the angular yaw velocity and acceleration, the steering angle, the side slip angle of the vehicle as well as the vehicle velocity and acceleration are established by inclusion of corrective quantities established, estimated and/or calculated in corrective step. By means of the corrective steps, the quantities dependent on wheel forces, intermediate quantities, or components are weighted in dependence on further measured quantities which have been established by conventional sensor devices, etc., and/or which represent the vehicle situation.

Dependent claims

A method for detemining vehicle status quantities, in which the forces acting on the individual wheels and tires are measured and evaluated for the establishment of control quantities for an automotive control system, comprising the steps of:

measuring tire force quantities including longitudinal and lateral tire forces, vertical tire forces of the wheels,
establishing vehicle status quantities including the angular yaw velocity or the angular yaw acceleration, the steering angle and the side slip angle of the vehicle as well as the vehicle velocity or the vehicle acceleration by using corrective quantities determined, estimated or calculated in corrective steps,
weighting the tire force quantities or components of these quantities in the corrective steps in dependence on at least one of the following measured, or calculated non-tire force quantities rotary wheel speed, cornering, straight ride, friction coefficient.

Dependencies are inferred from the claim text.
