“…The purpose design approach usually creates vehicle proportions that differ significantly from vehicles with conventional technology. It is undisputed that future, fully automated vehicles (SAE levels 4 and 5) will have different proportions, such as an extended wheelbase (Tzivanopoulos et al, 2015). Macey and Wardle (2014) emphasize that for new design projects, the architecture should be rethought every time "to make an exciting statement about its intended function."…”

For the user perception of vehicles and consequently the success of automobile design, the body layout and especially the proportions of vehicles are pivotal. In the present study, the SAE main dimensions length (L108), wheelbase (L101), height (H100) and width (W103) of 697 vehicles from different OEMs were examined. The analysis reveals a tendency of increasing length, wheelbase and especially width of vehicles in recent years. Regarding the ratios of these dimensions there are clear correlations, as revealed by an analysis with linear regression. We find particular strong synchrony in the increases of the pairs W103 - L108 and L101 - L108 and lesser so between the ratio E = L108/L101 and the vehicle length. The latter can be explained by vehicles with a high L108 being less compact, i.e. the proportion E increases. Finally, it is discussed whether technological changes lead to revolutionary or evolutionary changes in dimensions. The historical development and the moderate proportional changes of BEVs indicate a measurable but evolutionary development. In contrast, disruptive technologies such as automated driving can significantly change the vehicle layout and thus encourage a more revolutionary change in proportions.

“…Hence he or she gains time for nondriving-related tasks (NDRTs), such as sleeping, watching movies or working (Pfleging and Schmidt, 2015). Geometric space for performing these tasks needs to be considered in the early phase of the concept development of the vehicle and especially within the context of the design of the interior (Tzivanopoulos et al, 2015). The investigation of the collision free positioning of vehicle components with occupants takes place in the so called "package".…”

Caused by the technology of automated driving the user is temporarily released from driving and can perform non-driving-related tasks (NDRTs), such as sleeping or working. The aim of this paper is to describe the geometrical interdependencies between NDRTs and different vehicle types, to be able to integrate them in the geometric package of the early phase of the vehicle conception. To address the objective a literature based study of existing approaches for vehicle conception and NDRT-studies was carried out. Additionally interviews with n=15 experts from the automotive conception department and a databased analysis of n=259 vehicles was conducted. Based on these investigations 91 geometrical characteristics for NDRTs and vehicle types werde determined and combined through a matrix-based approach. By analysing the approach highly connected characteristics such as the torso angle were identified and equations were set up to describe the relations. The approach can be used for different NDRTs such as relaxing and working and different vehicle types such as sporty cars or SUVs in order to integrate them into the package.
