TLDR
The Magic Formula model as mentioned in this paper provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously.Abstract:
An account is given of the latest version 3 of the Magic Formula tyre model. The model provides a set of mathematical formulae from which the forces and moment acting from road to tyre can be calculated at longitudinal, lateral and camber slip conditions, which may occur simultaneously. The model aims at an accurate description of measured steady-state tyre behaviour. The coefficients of the basic formula represent typifying quantities of the tyre characteristic. By selecting proper values, the characteristics for either side force, aligning torque or fore and aft force can be obtained. The new version of the model contains physically based formulations to avoid the introduction of correction factors. Double-sided, possibly non-symmetric pure slip curves are employed as the basis for combined slip calculations. Suggestions are given to estimate the driving part of the longitudinal slip curve and to represent the characteristic at rolling backwards.read more

Fault-tolerant traction control of electric vehicles
TL;DR: In this paper, a fault-tolerant approach based on the maximum transmissible torque estimation (MTTE) scheme is proposed to prevent electric vehicles from skidding. But, the approach does not require the vehicle's chassis velocity to be monitored.

Measurement and modeling of skid resistance of asphalt pavement: A review
TL;DR: A review of the repeatability and harmonization of field-testing methods for macrotexture is outlined in this article, and the gap between lab test and field test for skid resistance should be bridged to realize more accurate estimation of pavement frictional properties in the phase of lab design.

Dealing with multiple contacts in a human-in-the-loop application
TL;DR: In this article, the authors proposed a continuous contact force model for collisions between massive solids for which the assumption of quasi-static contact holds and it can be supposed that the deformation is limited to a small region of the colliding bodies while the remainder of them are assumed to be rigid.

TL;DR: In this article, the Magic Formula Tyre Model is compared with the Monte Carlo version of the model and the comparison between the two versions shows that the latest version results in better fitting results especially for camber influences and (even more important) in an improvement on the fitting process.
