Delivering State-of-the-Art Functionality While Keeping Software Complexities Under Control with Minimal Impact on the Testing Process ECU CONSOLIDATION IN TOMORROW'S CONNECTED AND AUTONOMOUS CAR THE CHALLENGE Software drives the electronic control units (ECUs) that power everything in the car, from dashboard instruments to safety features to power train components to in-vehicle infotainment (IVI) systems. The functions performed by ECUs are also becoming increasingly sophisticated and complex. New features and capabilities such as adaptive cruise control, digital instrument clusters, and car-to-car or car-to- fleet communication are great for consumers, but they add complexity to an already difficult software development and testing process. Each ECU also has its own infrastructure components (such as power supply, bus, and diagnostics) and its own requirements with regard to functionality, safety, security, and dynamic behavior, requiring the use of multiple platforms and toolsets for development and testing. In addition, ECUs may have differing Automotive Safety Integrity Levels (ASILs) and ISO 26262 requirements. Selecting from among the array of proprietary and open source development, testing, and management options further complicates matters. How do you test and debug with all these permutations and complex interactions and interdependencies? How do you meet certification requirements in this environment? Above and beyond the technical intricacies of ECU consolidation, there are business issues to consider. Currently, ECUs are typically purchased as separate items, potentially from separate Tier 1 suppliers. If ECUs are consolidated and combined, who builds them? Who manages the multi-vendor sourcing, integration, and licensing issues? Who is responsible for maintaining and upgrading their functionality? How are faults isolated to an individual function? THE SOLUTION No single technology partner can resolve the business challenges of ECU consoli- dation, but the Wind River ® perspective is that a technical solution to consolidation will accelerate the resolution of business challenges. Therefore, we have dedicated our resources to that effort.
