Opis: In the bachelor’s thesis, advanced driver-assistance systems are discussed and explained. The focus of the explanation is placed on two specific systems, the anti-lock braking system and the automatic transmission system. To provide a deeper understanding of these systems, simulations were created using the computer program. Computer simulation is explained and the types of computer simulation are discussed. Programs used for computer simulation are presented and explained. The program used for computer simulation in this bachelor’s thesis is Scicos, and the visual and interactive representation of the anti-lock braking system and the automatic transmission system is made. For the anti-lock braking system, the simulation scheme is divided into models representing various components of the system, such as the vehicle, wheel, slip, friction, and control. Each of these models interacts with one another to replicate the functioning of the anti-lock braking system. Similarly, for the automatic transmission system, the simulation scheme is divided into models representing the driver and environment, engine, transmission, vehicle, and controller. These models interact to simulate the operation of the automatic transmission system. The thesis presents the results from the simulation of these two systems to analyze the difference in using the systems in different driving scenarios. The effect of the advanced driver-assistance systems in the vehicles is also showcased.
Ključne besede: Advanced driver-assistance systems, computer simulation, Scicos, anti-lock braking system, automatic transmission system.

Opis: V diplomski nalogi je predstavljena nastavitev referenčnega temperaturnega profila pretočne peči za strjevanje lepljenih elektronskih vezij na iterativenali eksperimentalni način ter na podlagi računalniške simulacije. V uvodnem delu je predstavljen opis idealnega referenčnega temperaturnega profila ter problematika starega lepila in hkrati uporaba novega lepila za lepljenje elektronskih vezij, ki je tudi vzrok za izdelavo novega temperaturnega profila. Temu sledi prikaz izdelave referenčnega temperaturnegaprofila na eksperimentalen ročni način. Za računalniško podprto načrtovanje profila pa je bilo potrebno izdelati najprej matematični model spreminjanja temperature v pretočni peči in ga nato na podlagi tega modela simulirati z orodjem za simulacijo. Na koncu sledi še izdelava referenčnega temperaturnega profila s simulacijo. Rezultat simulacije prikazuje referenčni temperaturni profil in potrebne temperaturne nastavitve na pretočni peči. Končni rezultat diplomske naloge je poleg primerjave obeh pristopov k izdelavireferenčnega temperaturnega profila tudi računalniška simulacija delovanja pretočne peči, v kateri lahko poljubno simuliramo spremembe temperaturnega profila v zelo kratkem času. Primerjava obeh pristopov je pokazala, da je pristop s simulacijo bistveno bolj hitrejši in primeren za uporabo.
