This annotated bibliography was developed as a means of creating a baseline of the state-of-the-art in vehicular software engineering. When we started the literature review for the project, the focus was on automotive software engineering, and as the review progressed, we realized the importance of expanding the scope to vehicular software engineering. Each of the three broad subsectors within the vehicular sector: automotive, trucks/buses, other specialty equipment; provide different insights into the challenges created by the use of software. Within the three sectors, the automotive sector has the highest volume, and at the same time is driven by the conventional pressures of lowering unit costs. The trucks/buses sector provides the greatest variation in software configurations since each buyer attempts to tailor the software components to their unique requirements. The specialty equipment sector has the least variance, but still leverages software to be a product differentiator.
