In order to enable vehicle functions to be safeguarded even with the first functional models of electrical control units, all well-known OEMs are now using hardware-in-the-loop (HiL) test benches, with appropriate control units either as isolated components or networked together To be able to test for any error patterns early in the development cycle.
Cost-effective electronics protection.
Since the classic function testing by performing lengthy and time-consuming and cost-intensive driving maneuvers is increasingly reaching its natural limits due to the ever increasing complexity of the underlying electronic components and driver assistance systems, the desire within the industry is increasingly increasing To be able to secure functions long before the first prototype vehicles are available while using real hardware.
Ultimately, this also enables shorter product development cycles to be continuously achieved.
Hardware-in-the-loop test methodology.
To achieve this goal, test benches are used that stimulate the control unit inputs and, if necessary, can record the control unit outputs even under real-time conditions.
Here, all communication partners of the control unit are
using so-called residual
via the vehicle's bus systems
The control unit as such functions here as a black box, the correct behavior of which is measured using the recorded system reactions and compared with corresponding reference values.
HiL automation systems.
Due to the high complexity of today's electronics and software components, security is no longer carried out manually nowadays, but in a highly automated manner through the use of modern test automation systems.
The ever increasing complexity of the vehicle components to be secured as well as the high degree of networking of these components leads to a constant further development of the underlying test methodologies and the respective test automation systems.
