In an automotive context today’s need of testing functions while in factory, correcting faults in the workshop or adding extra value in the aftermarket makes it very important to easily be able to download new software to the electronic control units in vehicles. In the platform for standard automotive software development called AUTOSAR, two known protocols are presented to specify the procedure on how to implement this download operation: Unified Diagnostic Services (UDS) and the Universal Measurement and Calibration Protocol (XCP). However the part of the UDS and XCP standards that is about reprogramming is not completely a part of the AUTOSAR standard yet. In this thesis, UDS and XCP have been compared to evaluate which of the two that has most support in AUTOSAR today and are most likely to be fully integrated into AUTOSAR in the future. Since UDS already has support in AUTOSAR for some of the functions needed for reprogramming and because of the fact that UDS is a part of the extensively used On-board Diagnostic standard (OBD-II), UDS is chosen to be the most suitable protocol for implementing reprogramming functionality according to AUTOSAR. A bootloader with the ability to download data has been developed using only relevant functions from UDS and following the AUTOSAR specifications where it is applicable. / För att kunna testa fordonsfunktioner i fabriken, åtgärda mjukvarufel under service eller för att uppgradera fordonet med nya funktioner är det viktigt att kunna ladda ner ny mjukvara till fordonets styrsystem. Den standardiserade mjukvaruplattformen för fordonsindustrin, AUTOSAR, innehåller två protokoll som båda specificerar hur mjukvara kan laddas ner: Unified Diagnostic Services (UDS) och Universal Measurement and Calibration Protocol (XCP). Tyvärr är de delarna av UDS och XCP som beskriver mjukvarunerladdning inte en del av AUTOSAR än. I det här examensarbetet har UDS och XCP jämförts för att utvärdera vilken av de båda som i dagsläget har störst stöd för nerladdning av mjukvara i AUTOSAR och vilken som troligast kommer att bli en del av AUTOSAR i framtiden. Eftersom AUTOSAR redan stödjer några av de funktioner i UDS som behövs för nerladdning av mjukvara samt på grund av att UDS är en del av branschstandarden för fordonsdiagnostik OBD-II, har UDS valts som den mest lämpade att i dagsläget användas för att implementera nerladdning av mjukvara enligt AUTOSAR. En bootloader som stödjer nerladdning av mjukvara via UDS har sedan implementerats enligt AUTOSAR-specifikationen så långt som möjligt.

In dieser Arbeit wird ein Applikationstool auf Basis des Kommunikationsprotokolls XCP entwickelt. Dieses verwendet die Ethernet-Transportschicht, um den Test von Steuergerätesoftware zu optimieren. Hierzu bietet das Applikationstool eine Schnittstelle an, die es Testautomatisierungslösungen ermöglicht, Variablen des Steuergeräts zu kalibrieren und per Polling oder synchroner Messung abzurufen. Aufgrund der hohen Performance, den geringen Entwicklungskosten und der guten Anwendbarkeit in der Testautomatisierung hebt sich das entwickelte Applikationstool von anderen auf dem Markt verfügbaren Tools ab. Zudem kann das Tool flexibel erweitert und auf die individuellen Bedürfnisse der Anwender angepasst werden. Die Architektur wird auf Grundlage wichtiger Design-Patterns erstellt, wodurch verschiedene Protokoll- und Hardware-Komponenten in einer abstrakten Weise dargestellt und miteinander verbunden werden können. Zuvor werden alle benötigten Daten aus den sogenannten A2L-Dateien ausgelesen, indem reguläre Ausdrücke und Grammatiken angewandt werden. Durch die entwickelte Architektur können ältere, aktuelle und auch zukünftige Steuergeräte zuverlässig ausgelesen werden. Des Weiteren erlaubt die Software-Struktur das flexible Hinzufügen verschiedener Hardware-Adapter und weiterer Kommunikationsprotokolle. Zur Evaluierung werden die einzelnen Komponenten mit realen Steuergeräten getestet und bezüglich ihrer Geschwindigkeit überprüft. Bei der Messung mittels Polling wurde eine durchschnittliche Zeit von 0.3ms pro gemessenem Wert erreicht, wobei die Latenz des Steuergeräts ungefähr die Hälfte der Zeit beansprucht. Für die synchrone Messung konnte eine Verarbeitungsgeschwindigkeit von ca. 500 Bytes/ms erreicht werden, was selbst in kleinen Messrastern eine Verarbeitung vor dem Eintreffen des nächsten Wertes ermöglicht.

Testing of the Electronic Control Unit is a very important step before delivering the software to customer. Due to increasing complexity in the requirements and the timing constraints, it is needed that the testing should be proper and on time. To meet the timing constraints it is needed to automate the entire process of testing. Although the current testing tool support the automation process, it is very slow. In this thesis a new tool has been developed which will support calibration using CCP and XCP on CAN bus. Secondly, the tool will also provide the feature of automation, where user can write their own script to test the ECU. This will make the entire process of testing very fast. Finally both the solutions will be compared with respect to time for deducing the final conclusion.

In the context of automotive industries today, the focus of ECU function development is always on finding the best possible combinations of control algorithms and parameter. The complex algorithms with broad implementation range requires optimal calibration of ECU parameters to achieve the desired behaviour during the drive cycle of the vehicle. With the growing function complexity of automotive E/E Systems, the traditional approaches of designing the automotive embedded systems are not suitable. In order to overcome the challenge of complexity, many of the leading automotive companies have formed a partnership in order to develop and establish an open industry standard for automotive E/E architecture called AUTOSAR. In this thesis, toolchain for ECU function development following AUTOSAR standard and an efficient measurement and calibration mechanism using XCP on CAN will be investigated and implemented. Two toolchains will be proposed in this thesis, describing their usage in different stages of ECU function development and in calibration. Both these toolchains will be tested to prove its working. / I området utveckling av funktionalitet på elektroniska styrsystem inom bilindustrin idag, ligger fokus på att finna den bästa kombinationen av reglermetoder och styrparametrar. Dessa avancerade system, med breda användningsområden, kräver bästa möjliga injustering av dess kalibrerbara parametrar, för att nå önskat beteende vid användning av fordonet. Det ökande omfånget av funktionskraven på styrsystemen, innebär att sedvanlig metodik för utveckling av dessa system inte är lämplig. För att kunna lösa dessa svårigheter, har de stora inom bilindustrin ingått ett samarbete, där de tillsammans skapat och utvecklar en industristandard för funktionsoch systemutveckling av styrsystem. Standarden kallas AUTOSAR. Denna rapport beskriver hur en kedja av utvecklingsverktyg som följer AUTOSAR-standarden kan användas, för att undersöka och använda en metod för systemövervakning och parameterkalibrering, genom användning av XCP över CAN.

Recently, there has been a significant surge of interest towards the design and development of a new global-scale communication network that can overcome the limitations of the current Internet. Among the numerous directions of improvement in networking technology, recent pursuit to do better flow control of network traffic has led to the emergence of several explicit-feedback congestion control methods. As a first step towards understanding these methods, we analyze the stability and transient performance of Rate Control Protocol (RCP).We find that RCP can become unstable in certain topologies and may exhibit very high buffering requirements at routers. To address these limitations, we propose a new controller called Proportional Integral Queue Independent RCP (PIQI-RCP), prove its stability under heterogeneous delay, and use simulations to show that the new method has significantly lower transient queue lengths, better transient dynamics, and tractable stability properties. As a second step in understanding explicit congestion control, we experimentally evaluate proposed methods such as XCP, JetMax, RCP, and PIQI-RCP using their Linux implementation developed by us. Our experiments show that these protocols are scalable with the increase in link capacity and round-trip propagation delay. In steady-state, they have low queuing delay and almost zero packet-loss rate. We confirm that XCP cannot achieve max-min fairness in certain topologies. We find that JetMax significantly drops link utilization in the presence of short flows with long flow and RCP requires large buffer size at bottleneck routers to prevent transient packet losses and is slower in convergence to steady-state as compared to other methods. We observe that PIQI-RCP performs better than RCP in most of the experiments.
