Yaw Instability Due to Longitudinal Load Transfer During Braking in a Curve

Active vehicle dynamics control ensures improved safety. So far, yaw instability is mostly associated with transient steering manoeuvres when driving at a constant speed. However, braking related load transfer affects yaw stability. Intense braking at high friction combined with elevated and forwarded CG amplifies this influence on unloaded tractors. Designing a dynamic stability system to enhance active safety requires fresh insight into braking related yaw instability. This investigation covers a theoretical analysis of braking influence on yaw stability on unloaded 4x2 tractors, being applicable to vehicle braking while cornering, including steering induced by other asymmetrical forces, since it focuses essentially on small steering angles.
