Abstract

An incremental message and task scheduling approach based on a time driven message schedule and priority driven task schedule is proposed. The hierarchical message and task scheduling methodology meets precedence, real-time, and deadline constraints. The global message system is supported by FlexCAN and the task scheduler system is supported by the AUTOSAR O.S. A detailed design example that includes a drive-by-wire application is used to illustrate the methodology.
