A Distributed In-Car Massage Application Based on Eclipse Chariott

With the steadily increasing amount of software in modern cars, traditional electric/electronic (E/E) architectures reach their limit when it comes to deploying complex applications, which often require the integration of various sensors, processing units, and software components, as well as higher bandwidth and processing power. To cope with this issue, more powerful computing platforms are being employed. One of the many new software projects that try to solve the challenges associated with these new platforms is Chariott, which provides a metadata-driven communication middleware that fosters the communication of distributed in-car applications through a common interface. Software components can register with Chariott to advertise their functionality. Software components that are registered with Chariott, referred to as providers, can then be found via service discovery. Alternatively, Chariott offers an intent-based approach where a broker maintains a mapping of intents and providers that can fulfill requests for these intents. Contrary to interfaces that define required implementation details, intents capture only the high-level purpose of a request as well as the required data. In this demo paper, we present our massage seat use case that was specifically designed to evaluate the suitability of Chariott for distributed in-car applications as well as our evaluation results.
