ENGINE-IN-THE-LOOP AS A DEVELOPMENT TOOL FOR EMISSIONS OPTIMISATION IN THE HYBRID CONTEXT
Hybrid concepts are advancing the degree of complexity of powertrains and the variety of their different versions. For that reason, the focus of attention is increasingly on energy efficiency and compliance with emissions standards under real conditions. As previous development methods based on studies of steady-state operating points, speed-load profiles or idealised driving cycles are reaching their limits, the recognition of operating phases that are critical for emissions and a targeted examination of the corresponding cause-effect relationships are decisive. This report describes processes that combine real tests with real-time-capable simulation, thus creating new possibilities for studying the entire powertrain development process and in particular the generation and reduction of emissions under realistic operating conditions.

CONSISTENT TEST METHOD FOR ASSISTANCE SYSTEMS
After HiL and SiL, new Vehicle-in-the-Loop (ViL) simulation is an innovative method to handle the complexity during functional validation of driver assistance systems and to decrease test effort at the same time. This method combines the advantages of test driving and simulation by integrating a real vehicle in a virtual traffic environment. IPG Automotive and FZI Research Centre for Information Technology developed the Vehicle-in-the-Loop test concept, with which assistance systems like parking assistant, traffic crossing assistant and pedestrian detection can be ensured amazingly.

REDUCED VALIDATION EFFORT FOR DYNAMIC LIGHT FUNCTIONS
Increasingly advanced driver assistance functions and their integration result in higher complexity of the systems and their validation. This also applies to dynamic light functions which provide situation-dependent headlight adjustment consisting of adaptive headlight, headlight leveling and (glare-free) high-beam assistance. The required road tests can often be performed only at night. BMW AG and IPG Automotive are developing a problem-solving approach here which makes it possible to significantly reduce the validation effort and to manage the requirements for safety-related functions associated with ISO 26262. It combines in-development testing and the standardised Functional Mock-up Interface (FMI) with the methods of virtual test driving.

TESTING AND SIMULATION-BASED VALIDATION OF ESP SYSTEMS FOR VANS
The Mercedes-Benz Vans division uses vehicle dynamics simulation to support the validation of the wide vehicle variance during the development of ESP systems. This process is based on a multi-step SiL data exchange with Bosch and is shown here using the example of the computational support of the ESP homologation for the variants of the Sprinter. This type of cooperation accelerates the system development for a large number of variants and offers potential for the application of further assistance functions.

The Steering-in-the-Loop method allows an efficient and comprehensive evaluation of steering behaviour and steering system functions even before real-world road testing commences. The open and modular structure of the CarMaker integration and test platform offers a wide range of applications combined with the reusability of tests and evaluation criteria as well as the reproducibility of the results obtained.

Mobile Machinery in Virtual Test Driving
The simulation based validation is a crucial step to support the development of mobile machinery. The method is strongly oriented towards real test driving and takes development engineers closer to the vehicle across multiple domains. In this process, the whole vehicle moves into the focus. In this way, complex interactions between mechatronic subsystems can be analyzed and optimized cost-efficient and at an early stage of development.
