Abstract:
A method of controlling a torque vectoring mechanism and an associated torque vectoring system are disclosed. The method can distribute torque between a left non-driven wheel and a right non-driven wheel of a vehicle based on a torque control value. The torque control value can be based on a change in yaw moment about a center of gravity of the vehicle. The change in yaw moment can be determined based on a reduction of lateral force on a driven axle due to both longitudinal and lateral slip on the driven wheels.

Es wird ein Verfahren zur Erhöhung der Genauigkeit einer Positionsverfolgung (02) eines Fahrzeugs in softwarebasierten Steuerungssystemen beschrieben, bei dem zur Positionsverfolgung (02) parallel Berechnungen nach zwei oder mehr unterschiedlichen Modellen (03, 04) durchgeführt werden, wobei die verwendeten Modelle (03, 04) so gewählt sind, dass Daten aus unterschiedlichen Quellen (05, 06, 07, 08) für die Berechnungen verwendet werden. Außerdem wird ein Computerprogrammprodukt beschrieben, welches einen einen Mikroprozessor mit zugehörigen Speichermitteln umfassenden MikroController zur Durchführung des Verfahrens veranlasst.

Abstract:
The invention relates to a method for determining vehicle status variables on the basis of forces exerted on the individual wheels. The forces are detected with the assistance of tire sensors, whereby the measured variables represent the tire longitudinal, lateral and vertical forces (FSi, FBi, Gi). Vehicle yaw angle rate, yaw angle acceleration, steering angle, slideslip angle, velocity and acceleration are determined by including detected, estimated and/or calculated correction variables in correction steps (K1, K2, K3). With the assistance of the correction steps (K1, K2, K3), the variables according to the wheel forces (FSi, FBi, Gi), intermediate variables, or components according to additional measured variables are weighted, said variables having been acquired by means of conventional sensor technology etc. and/or represent the driving situation.
