Offering flexibility, accuracy, and a small size/form factor, PROVEtech:µHiL from MBTech provides functional testing of electronic control units (ECUs). The system brings real-time hardware-in-the-loop (HiL) testing together with a compact and modular design. Based on preconfigured plug-in solutions, the essential features for an HiL test system, such as fault simulation, signal conditioning, and I/O hardware, are integrated. The cost-effective PROVEtech:µHiL is a reusable test system that offers shorter time to market as well as a possibility to test the large number of ECU variants with one test system. PROVEtech:µHiL also provides a flexible test system for HiL applications not only in the test labs but directly at the developer’s desk. A member of the PROVEtech family of products, the system integrates with other members of the family.
