The simulated testbed

Abstract

The use of hardware-in-the-loop tools and test automation in engine-management verification and validation has helped speed up development for car makers. System integration and hardware-software integration can be performed to a very detailed level, including the effect of interface tolerances, ensuring the completed designs interactions are predictable and robust. The use of hardware-in-the-loop verification and the associated simulations and models naturally leads to a reduction in the use of resources such as vehicles, end-of-line test facilities and the number of prototype parts and vehicles required supporting development. Furthermore, hardware-in-the-loop techniques have been shown to have applications outside the development process, including the rapid resolution of field issues, helping to limit potential customer dissatisfaction.
