1. 1. Creating a Virtual Tyre Temperature Sensor

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Oskar Zetterberg; Axel Tevell; [2023]
   Nyckelord :Tyre temperature; Virtual sensor; Soft sensor; Time series; Recurrent neural networks; LSTM; GRU; Mathematics and Statistics;

   Sammanfattning : To accurately determine the efficiency and range of an electric vehicle, one must be able to estimate the rolling resistance of the car. This is currently done using standardized methods developed under laboratory settings, where transient aspects and effects of varying temperatures are excluded. LÄS MER

3. 2. Tyre Performance Estimation during Normal Driving

   Master-uppsats, Linköpings universitet/Fordonssystem

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

   Sammanfattning : 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.

4. 3. The relation between rolling resistance and tyre temperature in real driving scenarios

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Hugo Jansson; Martin Åsenius; [2021]
   Nyckelord :tyre; tire; model; temperature; brush model;

   Sammanfattning : A large portion of the world’s total emissions is caused by the transport sector where rolling resistance is one of the contributing factors. The inner tyre temperature is a factor that greatly influences the rolling resistance. LÄS MER

5. 4. Analysis on Tyre Wear : Modelling and Simulations

   Master-uppsats, KTH/Fordonsdynamik

   Författare :Taozhi Wangs; [2017]
   Nyckelord :Brush model; Tyre wear; Thermal model; Friction model.;

   Sammanfattning : The tyre is an essential part of a road vehicle. It is in the contact between road and tyre that the forces that create the possibility for the driver to control the vehicle are generated. Tyres, however, wear down, which leads to both unhealthy wear particles and disposal of old tyres, both of which are harmful to the environment. LÄS MER

7. 5. A finite element material modelingtechnique for the hysteretic behaviour of reinforced rubber

   Master-uppsats, KTH/Hållfasthetslära (Avd.)

   Författare :Petter Lind; [2017]
   Nyckelord :;

   Sammanfattning : Reinforced rubber is thanks to its elastic and dissipative properties found in industrialapplications such as isolators, flexible joints and tires. Its dissipative propertied comes from material related losses which have the effect that energy invested when deforming the material is not retained when returning it back to its initial state.
