  1. 1. Adaptive Rolling Radius Estimation

    University essay from Linköpings universitet/Fordonssystem

    Author : Rickard Wretlind; William Wärn; [2023]
    Keywords : Rolling Radius; Estimation; Rolling Radius Estimation; Tire; Tires;

    Abstract : Tire tread health is essential for safe operation of a passenger vehicle. Worn out tires significantly increases the risk of traffic accidents and hydroplaning. This thesis investigates the possibility to detect tire tread wear by estimating the effective rolling radius of a tire. READ MORE

    Abstract : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. READ MORE

  4. 3. Energy efficient cornering : Simulation and verification

    University essay from KTH/Fordonsdynamik

    Author : Nicolas Luco; Keren Zhu; [2018]
    Keywords : Bicycle model; Energy consumption; Vehicle cornering behaviour; Yaw moment control;

    Abstract : The purpose of this master thesis is to study the energy efficiency of a vehicle when it is cornering. To achieve this, a Simulink model was built from a simple basic bicycle model and theoretically validated. This model was then analysed and successively improved by adding velocity and yaw moment control. READ MORE

  5. 4. Improving Traction Efficiency in Off-Road Vehicles - A Sliding Mode Approach

    University essay from KTH/Optimeringslära och systemteori

    Author : Payam Maroufi; [2018]
    Keywords : Slip efficiency; sliding mode controller; sliding mode observer; articulated vehicles; wheel loader dynamic.; Slipeffektivitet; sliding mode regulator; sliding mode observerare; ledat fordon; hjullastarens dynamik.;

    Abstract : This report evaluates the option of using an equal slip controller, an effective rolling radius and rolling resistance force observer in a 4WD wheel loader. The vehicle studied is an under development- vehicle designed by Volvo CE. READ MORE

  6. 5. Rolling resistance during cornering - Impact of lateral forces for heavy-duty vehicles

    University essay from KTH/Optimeringslära och systemteori

    Author : Helena Olofson; [2015]
    Keywords : Bicycle model; lateral forces; rolling resistance; velocity optimization; Cykelmodell; sidokrafter; rullmotstånd; hastighetsoptimering; bränsleförbrukning;

    Abstract : We consider first the single-track bicycle model and state relations between the tires’ lateral forces and the turning radius. From the tire model, a relation between the lateral forces and slip angles is obtained. The extra rolling resistance forces from cornering are by linear approximation obtained as a function of the slip angles. READ MORE
