Continuous Development of Highly Automated Driving Functions with Vehicle-in-the-Loop Using the Example of Euro NCAP Scenarios

Highly automated driving functions of the type currently being targeted for the near future are based on the interaction of several assistance systems. The actions of these assistance functions rely on an analysis of data from the virtual environment. Consequently, efficient development of individual advanced driver assistance systems (ADAS) that operate safely provides the basis for highly automated driving. The development and testing of such systems poses an enormous challenge to automobile manufacturers and automotive suppliers as the system complexity in the whole vehicle keeps growing. This includes the highly developed technical functions and increased interaction of the individual systems, as well as the growing complexity of the test scenarios in the field of advanced driver assistance systems. In the development process, this feat can only be mastered with assistance by virtual test driving. These factors are additionally intensified by external boundary conditions and regulations such as those specified and issued by legislators or testing organizations (for the European area, this is the European New Car Assessment Program—Euro NCAP). The seamless utilization of the CarMaker open integration and test platform in the field of advanced driver assistance systems provides a solution to meet the challenge of consistently growing testing requirements. This paper is intended to show how ADAS can be reproducibly tested and validated across the entire development process (MIL, SIL, HIL, and VIL). The utilization of the MIL method in particular makes it possible to easily test challenging maneuvers such as collision scenarios toward the end of the development cycle by embedding a real-word vehicle in a virtual environment. The proposal below will present the development work made possible by utilizing the VIL method as illustrated by the specific use case of defined Euro NCAP test scenarios.

Video Injection Methods in a Real-world Vehicle for Increasing Test Efficiency

There is one aspect all active safety systems have in common: they must deliver reliable functionality – which is subject to country-specific testing by various testing organisations. In Europe the independent Euro NCAP (European New Car Assessment Programme) organisation carries out these tests and evaluates new vehicles. One of the key criteria for Euro NCAP testing of current and future generations of advanced driver assistance systems (ADAS) is the reliability of detecting situations in which pedestrians or cyclists might be involved. One of the prerequisites for faultless functionality is extensive in-development testing, including a number of relevant scenarios. To generate appropriate sce© IPG Automotive

Modellbasiertes Testen am Motorprüfstand – Teilvirtuelle Untersuchung von Hybridantriebssystemen unter Realbedingungen

Im Zuge der zunehmenden Systemkomplexitat im Fahrzeug spielt das fruhzeitige Testen unter Realbedingungen im Gesamtfahrzeugkontext eine immer wichtigere Rolle fur einen effizienten Entwicklungsprozess. Besonders deutlich wird dies im Bereich der hybriden Fahrzeugkonzepte, da sie sich durch einen extrem hohen Grad an Vernetzung und Interaktion der Fahrzeugsubsysteme auszeichnen.
