Recently, designs for the automated highway systems (AHS) to improve the safety and efficiency of highways have attracted much attention. However, such large-scale and complex dynamic systems present a number of control issues. Part of the complication comes from the hybrid nature of these systems, which consists of both time-driven and event-driven dynamics. In this paper, an object-oriented approach towards a hybrid controller design for automated vehicles in an AHS is proposed. First, the unified modeling language (UML) is extended to model the hybrid controller with a clear and natural representation of the discrete event and continuous time behaviors. Then, since the AHS is typically a multi-agent system, the simulation of which is suitable to implementation by multi-threaded programming, a Java-based library is further developed to support the implementation. In our framework, Java provides an implementation path, while the extended UML provides a reverse engineering path for the hybrid controller design.
