The ongoing demand for reduction in vehicle development time and cost continues to increase the use of digital simulation in the automotive development process. Despite the many improvements in simulation software and methodology during the last decade, there is still significant demand and technical capability for enhancement. The introduced Center for Digital Vehicle Development is helping to lead the effort to bridge this gap and providing a platform for projects on method development and validation. To increase the speed with which these efforts progress, partners from the automotive industry are encouraged to participate directly in these investigations. It has been presented, that by the cooperation between single departments by coupling results from their standard development tools, like CFD simulation from aerodynamics and driving dynamics simulation from driving dynamics, can improve a simulation tool, which helps to predict the vehicle performance under natural stochastic side wind. This interdisciplinary approach requires a tight cooperation between the single technical disciplines, like it has been realized in the Center for Digital Vehicle Development (CDVD). The current work results showed the powerful possibilities that can be unlocked using digital simulations. They also revealed the need for additional detailed investigations concerning the transient aerodynamic effects, which occur under changing approach flow conditions. This will be within the focus of an upcoming project within the CDVD. In addition to connecting technical disciplines, the CDVD has also demonstrated the ability to connect the analysis needs of the automotive industry with the fundamental research required to solve the difficult problems and bridge the gap between research solutions and practical tools which are useful to industry development engineers. The roles are complementary: The industry practitioners communicate their engineering analysis needs and are ultimately rewarded with tools to meet those needs. The research community solves the most significant problems, as identified and prioritized by the industry. The tool developers refine the research solutions into appropriate and useful engineering tools for the industry. Through this cooperative arrangement, the entire automotive engineering process can move forward to take full advantage of the available simulation and measurement technologies.
