Modern automotive subsystems are no longer a heap of electro-mechanics but instead involve a number of Electronic Control Units (ECUs). Electronic Control Unit (ECU) has become the fundamental building block of any automotive subsystem and is interfaced with electro mechanics counterpart. To meet the system wide requirements, these ECUs are interconnected using the communication infrastructure. Although the communication infrastructure in terms of, predominantly, the CAN based vehicle network took its birth to enable ECUs to work in a coordinated manner in order to support system wide requirements, during the past decade, this infrastructure was also viewed as a potential means to incorporate extensibility in terms of addition of newer ECUs which are built for implementing additional requirements. With this paradigm, the number of ECUs started growing in a steep manner, uncontrolled and as a result, today, it is not hard to see a high segment automotive housing ECUs as large as 75-80. Hence, load balancing mechanisms are needed to ease ECU integration and for efficient utilization of CPU power in ECUs. In this paper, we explain the concept of load balancing on the basis of CPU utilization across ECUs.

This paper presents an advanced dynamically configurable middleware for automotive embedded systems. The layered architecture of the middleware, and the way in which core and optional services provide transparency and flexible platform independent support for portability, is described. The design of the middleware is positioned with respect to the way it overcomes the specific technical, environmental, performance and safety challenges of the automotive domain. The use of policies to achieve flexible run-time configuration is explained with reference to the core policy technology which has been extended and adapted specifically for this project. The component model is described, focussing on how the configuration logic is distributed throughout the middleware and application components, by inserting 'decision points' wherever deferred logic or run-time context-sensitive configuration is required. Included in this discussion are the way in which context information is automatically provided to policies to inform context-aware behaviour; the dynamic wrapper mechanism which isolates policies, provides transparency to software developers and silently handles run-time errors arising during dynamic configuration operations.

“…Here a task is a concurrent thread of an application program running on top of the real-time operating system (RTOS) and middleware at an ECU. We assume that the task-to-ECU allocation [8], [9] has been decided, and do not consider in this paper run-time task-migration [10]. The only action on the tasks is to switch them on or off and only the selected tasks will be scheduled in RTOS.…”

The configurations of an automotive embedded system are normally fixed in production and remain static over the vehicle lifetime. Future scenarios, however, call for more flexible configuration support. DySCAS (Dynamically Self-Configuring Automotive Systems) project aims to introduce context-awareness and self-management features into automotive embedded systems via middleware technologies. Contributing to online configuration decisions, this paper formalizes a fundamental self-configuration problem. It forms a basis for managing the cross interdependencies of configurational items, assessing the system-wide impacts of changes, and making dynamic decisions about new configurations.
