Technical Article: High-Rate Task Scheduling within AUTOSAR

Vector addresses the challenges of high-rate application task scheduling within an AUTOSAR system

The electrical and electronic (E&E) functions inside a modern vehicle have grown both in number and complexity; this new level of complexity has led automotive vehicle manufacturers and their suppliers to form the AUTOSAR partnership, to define a standardised yet feature-rich software architecture for within the vehicle Electronic Control Units. A common misconception is that high-rate application tasks cannot be scheduled within an AUTOSAR system. This article explains the mechanisms in place within the AUTOSAR operating system to handle the application scheduling requirements and how a successful configuration of the OS allows the software engineer to continue running the high-rate task schedules within an AUTOSAR system.
