Due to the high diversity in designs and variants, the mandatory introduction of Electronic Stability Control Systems (ESC) for commercial vehicles of new generations at Daimler AG poses a task that can only be accomplished with a comparatively high cost in time and money using prototype vehicles. Based on the revised regulation ECE-R13, a simulation-based approach is feasible. After a short outline of the legal requirements, like the usage of an acknowledged simulation tool, the integration of a software or hardware module in a vehicle simulation environment and the validation of this tool by calibration, their realization in the Daimler Trucks division will be demonstrated. On an example of the new ACTROS generation the flow of the simulation-based certification process will be described. It spans the basic maneuvers for measurement and simulation, calibration and validation of simulations and the applied methodology, documentation and release management approved by the "Kraftfahrt-Bundesamt". In this context the specifically developed and certified simulation tool EBSim will be presented, highlighting the TWT TestSuite as the central operating environment, triggering the simulation tools, managing and varying vehicle and simulation parameters, as well as providing automated validation and documentation. Thus it is possible to cover the whole range of commercial vehicles and identify critical types and variants for ESC homologation.
