Abstract

We describe the software architecture of an automated vehicle control system implemented in the PATH lab. The system is responsible for automatic lateral and longitudinal control of a set of vehicles traveling in a platoon formation at close distance and at high speeds [15]. The software architecture consists of a set of processes running concurrently and communicating through a publish/subscribe database. Some processes are triggered periodically by external inputs (e.g., from sensors) while others are triggered by events from other (internal) processes. We model the architecture as a set of periodic tasks each consisting of a sequence of sub-tasks with varying priorities [3,4]. We perform a schedulability analysis to check whether a set of timing requirements expressed as deadlines are met.
