Tire-road interaction: a multi-scale journey from rubber friction to tire vehicle braking performance
The understanding of tire performance during ABS braking is a complex task. The final ABS braking distance on dry, wet and icy roads is the result of several parameters interacting with each other on specific time (µs … s) and length (µm … cm) scales. These parameters describe the surface roughness and state, the tire tread compound and tire construction as well as the vehicle characteristics (like ABS controller, suspension, vehicle weight, etc.). See figures 1 and 2 for illustration. The work presented here targets the assessment of these key parameters at the actual tire operating conditions. Guided by the rubber friction theory published by B.N.J. Persson  and its numerous extensions, the key parameters for rubber friction have been identified and characterized in the appropriate parameter space.
