1. 1. Tyre Performance Estimation during Normal Driving

   University essay from Linköpings universitet/Fordonssystem

   Author : Marcus Grip; [2021]
   Keywords : tyre performance; tread wear; tyre wear; online estimation; friction performance; velocity performance; friction potential; longitudinal stiffness; tyre stiffness;

   Abstract : Driving with tyres not appropriate for the actual conditions can not only lead to accidents related to the tyres, but also cause detrimental effects on the environment via emission of rubber particles if the driving conditions are causing an unexpectedly high amount of tread wear. Estimating tyre performance in an online setting is therefore of interest, and the feasibility to estimate friction performance, velocity performance, and tread wear utilizing available information from the automotive grade sensors is investigated in this thesis.

3. 2. Road friction estimation using an artificial neural network in a simulated environment

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Jonas Karlsson; [2020]
   Keywords : Friction estimation; vehicle dynamics; vehicle simulation; artificial neural networks; Technology and Engineering;

   Abstract : With the transition of responsibilities from the driver to the automated driving systems in vehicles, the systems need to have been tested for an extensive list of test scenarios as the passengers require high trustworthiness. The friction coefficient for the tyre-road friction is of high importance for the control of the vehicle but the coefficient is dependent on the physical complexity and nonlinear behaviour of tyres and is difficult to measure.
