Design Criteria to Architect Continuous Experimentation for Self-Driving Vehicles
The software powering today's vehicles surpasses mechatronics as the
dominating engineering challenge due to its fast evolving and innovative
nature. In addition, the software and system architecture for upcoming vehicles
with automated driving functionality is already processing ~750MB/s -
corresponding to over 180 simultaneous 4K-video streams from popular
video-on-demand services. Hence, self-driving cars will run so much software to
resemble "small data centers on wheels" rather than just transportation
vehicles. Continuous Integration, Deployment, and Experimentation have been
successfully adopted for software-only products as enabling methodology for
feedback-based software development. For example, a popular search engine
conducts ~250 experiments each day to improve the software based on its users'
behavior. This work investigates design criteria for the software architecture
and the corresponding software development and deployment process for complex
cyber-physical systems, with the goal of enabling Continuous Experimentation as
a way to achieve continuous software evolution. Our research involved reviewing
related literature on the topic to extract relevant design requirements. The
study is concluded by describing the software development and deployment
process and software architecture adopted by our self-driving vehicle
laboratory, both based on the extracted criteria.Comment: Copyright 2017 IEEE. Paper submitted and accepted at the 2017 IEEE
