This thesis was carried out at Scania CV AB, at the cab software testing group, RCIV. One of RCIV’s responsibilities includes testing of the instrument cluster used in Scania’s heavy trucks and buses. Today, this is done semi-automated. The tests are executed automatically in Vector’s CANoe software but are verified manually by a tester who needs to observe the instrument cluster. We have investigated the possibility to automate this testing procedure with the use of a camera based vision system and have studied different solutions available on today’s market. We studied five company’s solutions for a complete, or partial, automated test environment solutions as well as the possibility to have Scania develop a system of their own. The pros and cons we have found along with the cost of the systems are listed in this report. We also built a prototype with one of the image processing software alternatives. Our investigation showed that an automated test environment with a camera based vision system could be very beneficial for RCIV and could support much of the current testing but the system must be fully verified before replacing today’s semi-automated tests.

[pt] A evolução do design de automóveis possui características interessantes, sob o ponto de vista da relação estético-funcional estabelecida em cada época. No início, os projetos de veículos únicos priorizavam a funcionalidade em detrimento do bem-estar do usuário. Com o tempo, esta maneira de se projetar foi sendo modificada, passando por períodos que valorizaram estritamente o desempenho, a aerodinâmica e a forma para um modelo onde a relação humano-máquina é o centro principal de estudo. Com novos e diferentes modelos de veículos, estes passaram a apresentar variações no posicionamento e projeto de comandos e mostradores, principalmente na região do cluster de direção. Desta forma, o presente estudo objetivou demonstrar que esta variação do posicionamento e de projeto gera confusão e erros de julgamento por parte do usuário, podendo ocasionar graves acidentes e incidentes durante a realização da tarefa, principalmente àquele que não está acostumado com o sistema a ser utilizado. Para comprovar esta hipótese, foi elaborado um estudo que, primeiramente, buscou entender o desenvolvimento dos comandos e mostradores automotivos e o uso de normas e recomendações de projeto para traçar um panorama da disposição das informações no interior dos veículos. Para o desenvolvimento da pesquisa, determinou-se o enfoque na categoria popular. O estudo do surgimento desta categoria, do panorama atual e do perfil do consumidor, contribuiu para se tentar observar o modelo mental dos usuários em relação ao posicionamento dos instrumentos. Para isso foram aplicadas diferentes técnicas, tais como um estudo comparativo dos modelos; a aplicação de questionários com usuários motoristas; e a realização de um grupo focal. O levantamento de dados contemplou ainda a realização de testes em um simulador real de interior de veículo. Outrossim, foi possível observar constrangimentos causados pela variação do projeto e pelo posicionamento de um grupo de comandos/mostradores do cluster e sugerir recomendações para projetos futuros. / [en] The evolution of automobiles design has interesting characteristics, under the point of view of the aesthetic-functionary relation established at each time.

In this way, the present study aimed to demonstrate that this variation of the positioning and project generates confusion and errors of judgment by the user, and can cause serious accidents and incidents during the accomplishment of the task, mainly to that user that is not familiar with the system to be used. To state this hypothesis, a study was elaborated that, first, searched to understand the automotive development of the commands and counters and the use of norms and recommendations of project to trace a panorama of the disposal of the information in the interior of the vehicles.

The paradigm of the automotive industry has changed, over the course of the last10-15 years. Electronics and software, have introduced in many dierents parts ofa vehicle and the drive-by-wire it is taking over the vehicle functions. Connectivityfunctionalities are increasing in the context of the automotive industry as well. Allthe aforementioned parts have more than one common link. This thesis project willfocus on one of these links, which is the security. The focus will be the CAN busprotocol and specically, on investigating the implications of an adversary havingphysical access in a vehicle. An experiment will be contucted as part of this thesiswork, by using open source hardware (Arduino and Raspberry Pi) and a Man-inthe-middle (MITM) attack scenario, will be implemented. The application, whichwill perform the MITM attack (small scale CAN bus fuzzer) will be developedduring this project and it will be distributed as an open source software afterwards.
