Article Description

Due to the dimensions of the tire-road contact area, transients in a tire last approximately 0.1 s. Thus, in the case of abrupt maneuvers such as ABS braking, the use of a steady-state tire model to predict the vehicle's behavior would lead to significant errors. Available dynamic tire models, such as Pacejka's MF-Tire model, are based on steadystate formulations and the transient behavior of the tire is included by introducing a first order differential equation of relevant quantities such as the slip angle and the slippage. In these differential equations the most significant parameter used to describe the transient behavior is the so-called relaxation length, i.e., the distance traveled by the tire to settle to a new steadystate condition once perturbated. Usually this parameter is assumed to be constant.
