The use of the Daimler driving simulator in commercial vehicles development is a major step forward in the integration of CAE methods in the development process. It adds confidence in the decisions made from the involved development teams and management, so that reliable concept decisions and layouts can be made in the early development phase, and the project targets can be tracked more precisely. The variance of the commercial vehicle program can be handled effectively when combining real-world testing and driving simulator application. The wide variety of the vehicle program has to be covered with dedicated real-time models on an appropriate level of complexity for driving dynamics and steering analysis. The real-time modeling has to be based on the know-how and data derived from detailed finite element suspension models and multi-body vehicle models. The fields of simulator application range from handling and steering layout, target value definition, simulation of failure events and dangerous driving situations to acceptance tests for driver assistance systems. The experience with test setups and the extension of features on demand, for example regarding environment simulation and available driving situations, continuously increase the efficiency and the possibilities of the simulator test. In the future, new interface methods between the vehicle model and the simulator like co-simulation and multi-core support of the simulation software Simpack 9 will enable using models with even more axles and tire-road contacts. This is attractive especially for tractor-trailer combinations. Also in the field of software-in-the-loop integration, further developments are planned, for example the integration of electric power steering control codes for vans.
