Abstract

Validation is considered to be the central activity in the product engineering process (PEP). It’s the only way to check the fulfillment state of the customer objectives by the product. Accordingly, the product validation should apply real customer use case scenarios as test cases in terms of maneuver cycles. That means for the area of vehicle development that the continuous interaction of the systems driver, vehicle and environment has to be examined. For this purpose, the integrated IPEK X-in-the-Loop Framework has been developed, which exactly meets those requirements. It allows the application of objective-oriented, cost- and time-optimized systems engineering either for virtual systems (Model-in-the-Loop) or for real systems (i.e. Vehicle-in-the-Loop). To show the added value of system oriented validation and especially of the integrated IPEK X-in-the-Loop Framework for product development, the development process of a universal, energy-efficient Driver Assistance System (DAS) of Continental TEMIC is exemplarily applied. The challenge in the project at hand was to develop a cost-reduced, universal add-on fuel saving plug-in DAS for small- and medium-sized cars using the AFFP© as driver guidance system. It was asked to provide noteworthy fuel consumption advantage; extendable by additional interactions with other DAS’s in order to easily increase its fuel-saving potential. The resulting, patented entire system, which allows up to 22 % fuel consumption reduction, depending on the driving situation and vehicle boundaries, is presented in this paper. Thereby, the main focus will be set on the validation of the development activities, which have been performed by application of the IPEK-XiL Framework, e.g. at the IPEK Vehicle-in-the-Loop test bench.
