1. Traction Adaptive Motion Planning for Autonomous Racing
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Autonomous driving technology is continuously evolving at an accelerated pace. The road environment is always uncertain, which requires an evasive manoeuvre that an autonomous vehicle can take. READ MORE

2. Tyre Performance Estimation during Normal Driving
University essay from Linköpings universitet/FordonssystemAbstract : 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. Evaluation of Traction Control Systems for an Electric Forklift Truck
University essay from Linköpings universitet/FordonssystemAbstract : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

4. Dynamic Torque Modeling of a Wet Lamella Clutch Pack
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

5. Extended and Unscented Kalman Filtering for Estimating Friction and Clamping Force in Threaded Fasteners
University essay from Uppsala universitet/Signaler och systemAbstract : Threaded fasteners tend to break and loosen when exposed to cyclic loads or potent temperature variations. Additionally, if the joint is held tightly to the structure, distortion will occur under thermal expansion issues. READ MORE
