Due to the higher complexity of electrified vehicles the requirements for vehicle components and vehicle design augment and new development tools are desirable. The following paper describes the design of a hardware-in-the-loop test bench along with its structure using Modelica and a Remote Process Communication library. The aim is to support the development of components and operational strategies under realistic boundary conditions illustrated by the example of a waste heat recovery system. The test bench is planned and built up within the scope of the public founded project qOpt at the Institute for Automotive Engineering (RWTH Aachen University) in cooperation with the Forschungsgesellschaft Kraftfahrwesen mbH Aachen and the Institute of Automatic Control (RWTH Aachen University).

New developments in passenger-car technology involve a multitude of special challenges that have to be met in terms of system complexity as well as cost, time and innovation pressure. The coordination with additional technology sectors also plays a major role, according to fka. The particular relevance of all these factors and architectures for achieving climate targets must be taken into account, and they must be subordinated to the topic of sustainable mobility.g What architectures of next-generation vehicle systems will look like is often and strongly discussed. Different understandings, terminologies, contexts and associations complicate the discussion. In addition, there are specific challenges based on established structures of business and industry [1]. Overall, there is a broad spectrum of diverse views and perspectives, rich in detail, with accompanying strategies, solutions and measures.

Neuentwicklungen in der Pkw-Technik bergen eine Vielzahl von besonderen Herausforderungen in sich, die es hinsichtlich Systemkomplexität sowie Kosten-, Zeit-und Innovationsdruck zu meistern gilt. Auch die Abstimmung mit zusätzlichen Technologiesektoren spielt eine Rolle, stellt die fka fest. Die besondere Relevanz all dieser Faktoren und Architekturen sollte für ein Erreichen der Klimaziele berücksichtigt werden, und diese müssen sich dem Thema Nachhaltigkeit der Mobilität unterordnen.
