  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. Vehicle Mass and Road Grade Estimation using Recursive Least Squares

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Erik Paulsson; Linnéa Åsman; [2016]
    Keywords : Technology and Engineering;

    Abstract : This Master’s thesis describes a method for real-time estimation of a vehicle’s mass for automobiles using recursive least squares. The method has its foundation in the longitudinal dynamics of the vehicle and is designed to be easy to adapt to different vehicle models. READ MORE
