1. 6. Fault Detection and Diagnosis for Automotive Camera using Unsupervised Learning

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ziyou Li; [2023]
   Keywords : Unsupervised Learning; Autoencoders; Image Clustering; Fault Detection and Diagnosis; Morphological Operations; Hardware-in-Loop; Advanced DriverAssistance System; Oövervakad inlärning; Autoencoders; Bildklustering; Felfindning och Diagnostik; Morfologiska Operationer; Hardware-in-Loop; Avancerade Förarassistanssystem;

   Abstract : This thesis aims to investigate a fault detection and diagnosis system for automotive cameras using unsupervised learning. 1) Can a front-looking wide-angle camera image dataset be created using Hardware-in-Loop (HIL) simulations? 2) Can an Adversarial Autoencoder (AAE) based unsupervised camera fault detection and diagnosis method be crafted for SPA2 Vehicle Control Unit (VCU) using an image dataset created using Hardware-inLoop? 3) Does using AAE surpass the performance of using Variational Autoencoder (VAE) for the unsupervised automotive camera fault diagnosis model? In the field of camera fault studies, automotive cameras stand out for its complex operational context, particularly in Advanced Driver-Assistance Systems (ADAS) applications. READ MORE

3. 7. Fault diagnosis of a variable pole-phase motor

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Claes Henriksson; [2023]
   Keywords : Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

   Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE

4. 8. Fault detection and diagnosis through tool based expert rule methodology

   University essay from KTH/Hållbara byggnader

   Author : RODRIGO ESTUARDO PÉREZ ARBIZÚ; [2023]
   Keywords : ;

   Abstract : This thesis aims to develop a set of expert rules for fault detection and diagnosis,specifically for the Korsningen HVAC system, which has different sections, includingheat pumps, ventilation, supply/return hot and cold, chill beams, and radiators.The analysis focuses on identifying the most important sensors and other componentsthat provide valuable information to compress the data and improve systemreliability, reduce downtime, and increase efficiency.

5. 9. Data-driven Fault Detection and Diagnosis inHardware-in-the-loop Environment

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Arya Farhang; [2023]
   Keywords : ;

   Abstract : The automotive industry has grown rapidly in the previous decades, and with the move toward electrification and driving assistance, the need for faster testing and development is rising.Model-based design(MBD) development cycles partly address the issues by allowing testing to happen before the physical product is created.

6. 10. Weakly-Supervised Diagnosis with Attention Models

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zaoshi Ying; [2022]
   Keywords : ;

   Abstract : With the rapid development of data-driven solutions, a high-quality dataset with fine labels can well tackle fault diagnosis problems. However, in industry assets, the quality of the dataset depends much on the experience and capability of the annotation engineer. Therefore, strong labels are usually hard and expensive to acquire.
