  1. 1. Sensorless Field-Oriented Control and Position Estimation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Roberts Bitenieks; Lars Brander; [2023]
    Nyckelord :Sensorless rotor position estimation; High-frequency injection; Technology and Engineering;

    Sammanfattning : This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. LÄS MER

  3. 2. Vehicle systems representation through product architecture views

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Amey Anjankar; Akshay Mohan; [2023]
    Nyckelord :;

    Sammanfattning : This thesis aimsto identify and propose suitable product architecture views in order to facilitate efficient cross-functional communication and collaboration on architecture-related tasks. It thereby focuses on the relationships between components of a system while determining a suitable level of detailing which is called level of abstraction for the relationships the components share.

  4. 3. Masters Thesis - Estimating Overlap of Verification and Testing Efforts Between Different Test Levels

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :SELOMIE KINDU EJIGU; ROHINI BISHT; [2022-10-10]
    Nyckelord :V-model; overlapping; embedded system; redundancy; gap analysis; verification and validation;

    Sammanfattning : Context: Embedded systems (ES) are continuously growing in complexity and size in the automotive industry. The embedded software makes a larger part of the ES. Likewise, the testing process has become complex, larger, and difficult to control. This has led to the growing demand for test methods that would help to manage the testing process. LÄS MER

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

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Gabriel Fredriksson; [2022]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Continued integration of simulated vehicle model for software verification in CANoe and Simulink

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Johan Persson; [2020]
    Nyckelord :CANoe; CAN; BorgWarner; Simulation; Vehicle Model; Test; Technology and Engineering;

    Sammanfattning : This Master’s thesis investigates if a previously integrated Simulink based vehicle model works for testing and verifying software on an ECU (electronic control unit) used to control a four-wheel drive coupling in cars. The testing is done through a specific program called CANoe that allows the tester to both develop and run test cases. LÄS MER
