Today car manufacturers are expected to deliver cars configured
for each customer. Through software, and by adapting software
product line methods, car manufactures respond to the increased
customization needs. This emphasizes the need for careful variant
handling. Thus, based on a problem definition from Volvo Cars
this case study explores variation techniques to support massive
numbers of built-to-order cars using AUTOSAR. In essence, this
study argues that run-time variability, tested with a prototype development,
is a way to meet this need. It establishes the publishersubscriber
pattern as a viable run-time variation mechanism, and
identifies limitations and areas to consider related to subscription
management, real-time performance and data transparency within
an automotive environment. Finally, this study also demonstrates
how run-time variability enables manufacturers to better support
after-market services and enable 3rd party integration
