System Engineering of GM's Global Automotive Electronics, Controls and Software Product Line: Current Practice and Challenges
GM Research & Development
General Motors sells over 9 million vehicles across 157 countries. As a consequence, GM's development processes must be able to produce tens of thousands of product variants each calendar year to meet world-wide market demands. This presentation describes GM's system engineering approach to developing an electronics, controls, and software product line. These methods include explicit modeling of the product line structure and linking this model to tools used to manage requirements and software components. This presentation also discusses emerging challenges related to the increasing number of features that span traditional system boundaries, and the need for multi domain simulation and analysis to support development of these features. Also needs are identified related to supporting electrical system architecture trade studies to evaluate alternatives based upon metrics such as power, cost, and mass.
Dr. Joseph D'Ambrosio is a Lab Group Manager at GM Research Laboratories, and has worked in the automotive industry for over 25 years. He is currently involved in model-based system and software development techniques, including virtual development, optimization, and multicore strategies, as well as methods for developing safe and secure systems. D'Ambrosio served as a member of the USTAG and as an ISO Technical Expert in the development of the ISO 26262 Automotive Functional Safety Standard. He has prior experience in the development of automotive steering and braking systems, including steer- and brake-by-wire applications. D'Ambrosio received a Ph.D. degree in computer science and engineering from the University of Michigan. He is a member of the SAE and has over 50 technical publications.
