90% of the traffic-relevant information required to perform the task of driving are absorbed visually. Other sensory perceptions play a subordinate role when driving a motor vehicle. A distinction is made between direct vision and indirect vision from the vehicle. As there is a difference between the legally prescribed fields of vision and the ranges of indirect vision used by the driver depending on the situation, the dynamic eye point movements and the resulting field of vision shifts should be analyzed in greater detail. A methodology for determining the real vision situation-dependent ranges of indirect vision is required to optimize conventional mirror systems and design innovative vision systems. Information which enables dynamic vision situations to be integrated into the ergonomic design of commercial vehicles is required. To do this, dynamic eye point positions linked to additional information are recorded in real, representative, conventional vehicles during dynamic vision situations. These data are then processed using filter functions and the data of relevance to the specific ergonomic design situation are subsequently created and made available in the form of design geometries. In the development of vision systems, this involves real areas of indirect vision in commercial vehicles. Data are collected in extensive test drives to test the established methodology. Here in particular, importance is placed on the realism of the task of driving in long-distance haulage. A CAD model is established to determine real areas of indirect vision in commercial vehicles. The presented methodology is applied by processing the raw data, creating the CAD data and using the design geometry.
