Scalable ECU Network in-the Loop

The number and range of functions available in electronic control units (ECUs) distributed across all vehicle domains have seen a further sharp increase in recent years. Consequently, so has the amount of testing that needs to be done. After all, these functions need to be thoroughly tested and verified – and the trend toward greater connectivity is making these tests significantly more complex. Besides testing the individual components, engineers also have to look at the interaction among the ECUs. This calls for HiL systems that intelligently and flexibly connect tried and tested components.
