“…The creation of quantitative tyre wear models is a complex task and is currently a highly active area of research [19,20]. Accurate tyre wear predictions over a typical race distance are important since they help race teams to make tactical decisions regarding race-strategy.…”

“…Accurate tyre wear predictions over a typical race distance are important since they help race teams to make tactical decisions regarding race-strategy. In this analysis, the qualitative approach proposed in [20] is used to demonstrate the potential of LSD configuration to influence tyre wear. The rate of tyre wear W r , can be described as the amount of rubber lost from a unit surface per tyre revolution.…”

“…The rate of tyre wear W r , can be described as the amount of rubber lost from a unit surface per tyre revolution. A common assumption is that this is proportional to the amount of frictional work W f , performed by the tyre [19,20]. The wear rate can be described by the expression:…”

Modern motorsport limited slip differentials (LSD) have evolved to become highly adjustable, allowing the torque bias that they generate to be tuned in the corner entry, apex and corner exit phases of typical on-track manoeuvres. The task of finding the optimal torque bias profile under such varied vehicle conditions is complex. This paper presents a nonlinear optimal control method which is used to find the minimum time optimal torque bias profile through a lane change manoeuvre. The results are compared to traditional open and fully locked differential strategies, in addition to considering related vehicle stability and agility metrics. An investigation into how the optimal torque bias profile changes with reduced track-tyre friction is also included in the analysis. The optimal LSD profile was shown to give a performance gain over its locked differential counterpart in key areas of the manoeuvre where a quick direction change is required. The methodology proposed can be used to find both optimal passive LSD characteristics and as the basis of a semi-active LSD control algorithm.

Two types of radial tire 11.00R20 and 385/65R22.5 are chosen as the research objects, and their carcass contours are redesigned by using Sakai Hideo's, Frank's and the new non-natural equilibrium contour design theories, which were based on analyzing the current non-equilibrium contour design theories of radial tire. Then the tire wear, rolling resistance and grip performance of the two radial tires designed by different non-natural equilibrium contour design theories are comprehensively analyzed with the finite element software ABAQUS. The results show that Frank's contour design theory can reduce tire wear; the new non-natural equilibrium contour design theory can enhance tire wear, rolling resistance performance, etc. It is also found that the tire carcass contour has great influence on tire performance, especially on the tire rolling resistance. The new non-natural equilibrium contour theory provides a guidance to reduce the tire rolling resistance, and it can break through the target conflicts in tire performance. The tire with the new non-natural equilibrium carcass contour can enhance its comprehensive performance.

“…12 In a recent study, an approach combined with vehicle dynamics and qualitative formula for tire wear is proposed to estimate the tire wear quantity during longitudinal and cornering maneuvers. 13 However, few research attempts have been made to investigate TWQD between four wheels with consideration of the vehicle dynamics based on road properties.…”

Tire wear quantity and difference is one of the main points that affect the intension of tire road print feature and is under a tight link not only with tire road friction energy but also with vehicle dynamics. The proposed methodology aims to provide a mathematical method to analyze tire marks' feature for prediction the vehicle operating status in pro-and post-crash phases. The kinetic sliding friction coefficient considering the road effect is simplified with the new real contact area model. After, a simplified 9 degrees of freedom vehicle dynamics model by coupling the tire dynamic model is set up, and the effectiveness of the model is evaluated with vehicle stability measurement equipment. Furthermore, a theoretical model of tire wear quantity and difference as a function of road properties and vehicle dynamics is set up combined with vehicle-road coupling algorithm, and important parameters (e.g. vehicle speed, steering angle, braking force, and road feature) are analyzed to assess the tire wear quantity and difference feature when the vehicle is in unsteady condition. Results show that vehicle speed, braking force, and road surface feature have a significant impact to tire wear quantity and difference, the right rear exhibits a fluctuation and the tire wear quantity and difference between rear axle and the right side is obvious, and lay a strong foundation for tire road print analysis.
