1. 1. Creating a Virtual Tyre Temperature Sensor

   University essay from Lunds universitet/Matematisk statistik

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

   Abstract : 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. READ MORE

3. 2. Prognostics for Condition Based Maintenance of Electrical Control Units Using On-Board Sensors and Machine Learning

   University essay from Linköpings universitet/Fordonssystem

   Author : Gabriel Fredriksson; [2022]
   Keywords : machine learning; random forest; random survival forest; condition based maintenance; cbm; reliability; solder joint failure; thermomechanical cycling; ECU; lifetime prediction; data-driven; statistics; BGA; PCBA; field quality; maintenance; truck; bus; vehicle;

   Abstract : In this thesis it has been studied how operational and workshop data can be used to improve the handling of field quality (FQ) issues for electronic units. This was done by analysing how failure rates can be predicted, how failure mechanisms can be detected and how data-based lifetime models could be developed. READ MORE

4. 3. On-board processing with AI for more autonomous and capable satellite systems

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Tamina Lund; [2022]
   Keywords : Satellite telemetry forecasting; battery degradation prediction; LSTM; artificial intelligence; on-board processing;

   Abstract : While the use of Artificial Intelligence (AI) has faced a sharp up-rise in popularity in ground-based industries, such as for autonomous navigation in the automotive industry and predictive maintenance in manufacturing processes, it is yet only rarely used in space industry. Hence, this thesis aims to investigate the possibilities of using AI for processing on-board Earth-orbiting satellites while in orbit. READ MORE

5. 4. Technologies and Evaluation Metrics for On-Board Over the Air Control

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Aneysha Datta; [2022]
   Keywords : Wireless; Performance Metrics; WAVE; DMG; Intra-Vehicular Communication; BER; Simulink; Model-Based Design;

   Abstract : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. READ MORE
