Increasing customer demands and stricter legal standards require faster and more efficient development phases in the mobility sector. Frontloading of development tasks with the help of component test benches embedded in vehicle simulations can help to reduce costs. The quality of the results and the reduction of costs depend strongly on the vehicle simulation and integration of the test bench. This work investigates a holistic concept for the integration of a combustion engine test bench in a vehicle co-simulation. The vehicle simulation is decisive for the later results. For this purpose, a method of distributed modelling (co-simulation) is explained and the vehicle co-simulation consisting of the components combustion engine, powertrain, virtual control units and vehicle dynamics is described. The next step involves the classification of relevant test bench control methods and a discussion of the special features of an embedded / coupled test bench. The embedded test bench differs from the conventional test bench in the bidirectional influence of co-simulation and test bench. The resulting differences are investigated theoretically and by simulation. It is shown that the type of torque and speed returned to the simulation has a significant influence on the results. The test bench controller and its control quality significantly influence the results and the integration effort. Therefore, a real-time capable model predictive control to improve the control quality is presented. A key feature of the controller is its easy re-usability and integration in the used real-time hardware. Simulation and experimental results on a real test bench show a considerable improvement of the control quality.
