Abstract
Tato diplomová práce se zaměřuje na problematiku výpočtu
dojezdu elektromobilu a implementaci diagnostického systému
prostřednictvím OBD-II protokolu. V rámci práce byl navržen
a realizován komplexní systém, který umožňuje přesné určení
zbývajícího dojezdu vozidla na základě aktuálního stavu nabití
baterie, spotřeby energie a dalších relevantních parametrů. Práce
zahrnuje teoretickou analýzu existujících metod a technologií
používaných pro výpočet dojezdu, návrh algoritmů a jejich
implementaci na platformě mikrokontroléru STM32.
Experimentální část práce byla realizována na vozidle eŠus,
které bylo vyvinuto na Technické univerzitě v Liberci. Toto
vozidlo posloužilo jako testovací platforma pro vývoj a ověřování
navržených algoritmů a systémů. V práci byly implementovány diagnostické funkce založené na OBD-II protokolu, které
umožňují sběr a analýzu dat z vozidla v reálném čase. Testování
navrženého systému probíhalo v reálných podmínkách a prokázalo
jeho schopnost poskytovat přesné odhady dojezdu a spolehlivou
diagnostiku vozidla.
This thesis focuses on the problem of estimating the range of an electric vehicle and implementing a diagnostic system via the OBD-II protocol. A comprehensive system was designed and implemented, enabling accurate determination of the vehicle's remaining range based on the current state of battery charge, energy consumption, and other relevant parameters. The thesis includes a theoretical analysis of existing methods and technologies used for range estimation, algorithm design, and their implementation on the STM32 microcontroller platform. The experimental part of the thesis was carried out on the eŠus vehicle, developed at the Technical University of Liberec. This vehicle served as a testing platform for the development and verification of the designed algorithms and systems. The work involved implementing diagnostic functions based on the OBD-II protocol, allowing for real-time data collection and analysis from the vehicle. Testing of the designed system was conducted under real-world conditions and demonstrated its ability to provide accurate range estimates and reliable vehicle diagnostics.
