Análise de técnicas de testes funcionais e de caixa-branca aplicadas em ECUs

Abstract

The automotive industry is in constant technological advancement, therefore, it constantly brings new challenges to engineering. In order for a vehicle to be produced in a reliable and safe way for its users, there are a series of regimentations and protocols that seek to ensure that this happens, including some that guarantee the quality of the software embedded in ECUs. This work aims to analyze some possible test techniques performed on ECUs based on the ISO 26262 standard and in order to ensure high ASPICE qualification for supplier companies, being a work that approaches these subjects in a theoretical way. Concepts of vehicular electronic architecture and the automotive software development cycle will be presented, in addition to bringing concepts and practices to be considered when performing tests at all levels. The white-box and functional testing techniques will be detailed, presenting some techniques that are mandatory in each category according to ISO 26262, bringing very didactic examples in order to facilitate understanding.
