Demo abstract: Multi-modal scheduling of radar-based cruise control system

The interaction of a cyber-physical system (CPS) may impose additional constraints upon cyber aspects of the system. For instance, sensing and actuation often require non-preemption to ensure “accuracy” in data acquisition (e.g., radar sensors in automotive a cruise control system). Furthermore, CPS may require that a system adapts to changing environment which requires support for multiple operating modes. A multimode CPS may also enable resource-efficient solution by providing shared processing platforms to subsystems. Recent development [1] of multi-modal fixed-priority schedulability with non-preemption can facilitate multi-modal CPS-based design. In this demo, we present the benefits of such design choices by devloping a simple automotive adaptive cruise control (ACC) system using System objectsTM and Phased Array System ToolboxTM, which provides state-of-the-art tools for radar simulation. The ACC application composes tasks for radar transmission, reception, and controller upon a single processing platform. We consider radar transmission and signal receiving tasks to have non-preemptible execution regions.
