Process for determining vehicle dynamics

A process for determining at least one dynamic of a vehicle, particularly slip angle, during travel. The process involves optically monitoring, in real time and from the vehicle itself, the movement in one or more camera images of surface features as the vehicle passes over the surface. The directio...

Zusammenfassung:	A process for determining at least one dynamic of a vehicle, particularly slip angle, during travel. The process involves optically monitoring, in real time and from the vehicle itself, the movement in one or more camera images of surface features as the vehicle passes over the surface. The direction in which the surface features are moving at any given time indicates the actual direction of vehicle movement with respect to the orientation of the optical monitoring equipment. From this actual direction of movement, in combination with the known orientation of the optical monitoring equipment and the direction in which the vehicle is being steered, it is possible to calculate the slip angle in real time.
