Modern vehicles contain extensive hardware and software functionality that has to be checked, verified and safeguarded from all sides. This task is particularly challenging because it takes a longtime during vehicle engineering before these components are installed in a real vehicle and can thus be tested in a real environment. With individual function and hardware-in-the-loop (HiL) test systems, any conceivable test scenario can be covered and easily simulated in the laboratory without risking real vehicles or endangering the lives of test drivers.

In daily operation, ECUs in the vehicle are exposed to a wide range of environmental influences, such as vibrations, strongly fluctuating ambient temperatures and high humidity. The components must therefore be able to handle all conceivable faults. For the test, these faults are simulated on the ECU pin and the respective behavior and diagnostic entry documented. Typically, such fault simulations are used for function tests during development, for testing, release and validation of ECUs and components, as well as for integration validation during HiL testing or at the Functional Mock-Up (FMU).

It is a long journey from the start of engineering to the installation of all vehicle components and ECUs in the production vehicle. Comprehensive testing of the electronic components during the entire engineering process is essential. This is the only way to thoroughly safeguard and optimize hardware and software functions. Errors can be detected and remedied quickly – the earlier the better.
