Abstract [en]

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.

Abstract [sv]

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.
