Against the backdrop of progressively stringent legal requirements for emissions and carbon dioxide, new types of vehicle drives (electric or hybrid), new mobility models (car sharing or intermodality) and autonomous driving, knowledge about real-life daily driving on the road is increasingly important compared to the endurance runs driven by test drivers in development vehicles. FKFS has a great deal of experience in determining load profiles of this kind. All kinds of approaches are used here. For example, data loggers in end customer vehicles or vehicle fleets, measurement run studies with a representative group of test subjects on a circuit representative of driving in Germany – right through to determining load collectives using traffic simulations of traffic scenarios which do not yet exist in reality, e.g. scenarios with a high proportion of autonomous vehicles, or places which are too far away for real measurements.
