Load Balancing towards ECU Integration

There has been an exponential increase in the number of electronic components embedded in vehicles. Development processes, techniques and tools have changed to accommodate that evaluation. A wide range of electronic functions such as navigation, adaptive control, infotainment, traffic information, safety system etc are implemented in today’s vehicles. Many of the new functions are not stand alone and hence they need to exchange information, sometimes with stringent time constraints for time critical functions such as engine management, collision warning systems etc. The complexity of the embedded architecture in a vehicle is continually increasing. Today up to 2500 signals are exchanged through up to 70 Electronic Control Units (ECUs) using 5 different buses. This paper introduces the load balancing approach across ECUs supplied by various Tier1 suppliers

Rapid prototyping of distributed systems of electronic control units in vehicles

Existing vehicle electronics design is largely divided by feature, with integration taking place at a late stage. This leads to a number of drawbacks, including longer development time and increased cost, both of which this research overcomes by considering the system as a whole and, in particular, generating an executable model to permit testing. To generate such a model, a number of inputs needed to be made available. These include a structural description of the vehicle electronics, functional descriptions of both the electronic control units and the communications buses, the application code that implements the feature and software patterns to implement the low-level interfaces to sensors and actuators.

Modellbasierte Entwicklung und Konfiguration des zeitgesteuerten FlexRay Bussystems

Die stetige Erhöhung der Verkehrssicherheit durch immer leistungsfähigere Fahrerassistenzsysteme haben in den letzten Jahren maßgeblich zu einem Anwachsen des Elektrik/Elektronik Anteils im Automobilbau geführt. Diese Arbeit liefert einen Beitrag zur Verbesserung der Methoden für die modellbasierte Entwicklung und Konfiguration von FlexRay Bussystemen. Dazu wurden verschiedene Verfahren entwickelt, welche sich mit der Realisierung, Konfiguration, Validierung und Test von FlexRay beschäftigen
