“…Most of these methodologies consider electrification as new technology [13,14]. Since, to our knowledge, no methodology for concept design optimization of autonomous vehicles exists [1] (p. 6), we adapt the existing ones [15]. The consideration of the auxiliary consumers is an important part of this, because, as mentioned above, their consumption can account for a high proportion of the total consumption [15].…”

“…We, therefore, use the current version of the autonomous vehicle development tool (AuVeCoDe), which will be provided as open source MATLAB simulation within the dissertation of the first author next year. The first concept of this research was published in [15] and it has now been extended with several already published and validated models:…”

Automation and electrification are changing vehicles and mobility. Whereas electrification is mainly changing the powertrain, automation enables the rethinking of the vehicle and its applications. The actual driving range is an important requirement for the design of automated and electric vehicles, especially if they are part of a fleet. To size the battery accordingly, not only the consumption of the powertrain has to be estimated, but also that of the auxiliary users. Heating Ventilation and Air Conditioning (HVAC) is one of the biggest auxiliary consumers. Thus, a variable HVAC model for vehicles with electric powertrain was developed to estimate the consumption depending on vehicle size and weather scenario. After integrating the model into a tool for autonomous and electric vehicle concept development, various vehicle concepts were simulated in different weather scenarios and driving cycles with the HVAC consumption considered for battery sizing. The results indicate that the battery must be resized significantly depending on the weather scenario to achieve the same driving ranges. Furthermore, the percentage of HVAC consumption is in some cases higher than that of the powertrain for urban driving cycles, due to lower average speeds. Thus, the HVAC and its energy demand should especially be considered in the development of autonomous and electric vehicles that are primarily used in cities.

“…Besides electrification, automation as a second new technology will change the vehicle, as we know it today. To profit from this new technology as well, the authors develop a suitable purpose design for AVs (König et al, 2019). This method should help engineers avoid late changes and numerous iteration loops, which can lead to high costs and further changes (Lindemann et al, 2009, p. 1).…”

Autonomous driving will not just change vehicles themselves, but also the entire concept of mobility. New business models and the expansion of individual mobility to new groups of society are merely examples of possible impact. In order to create optimal vehicles for new technologies right from the start, vehicle concept optimization helps to find suitable solutions from numerous possible variations. The package as part of a vehicle concept is currently focused on passenger cars with steering wheels and pedals. Therefore, a new method is needed to plan the package of driverless and autonomous vehicles. In this paper, we present a possible method that separates the vehicle into the interior and the front and rear wagon. This way, different seating layouts can be considered and evaluated in terms of package efficiency. In the results, we check the plausibility by rebuilding a current battery electric vehicle (BEV) and, by way of example, show the variation of the gear angle and different seating layouts, and the resulting package efficiency.

“…The new whole vehicle properties they identify are Boarding, Quality of Secondary Activity, Updatability and Environmental Communication. Koenig et al (2019) show the influence of auxiliary consumers on the AVC. Some components and modified use cases increase the total energy demand of the vehicle, to which the AVC must be adapted.…”

Vehicle concept development is a domain that has applied and detailed its process over decades. The megatrends of the 21st century of “automation” and “sharing” influence the vehicle concept in such a manner that this well-running process needs an update. The vehicle itself and the customer of the vehicle are changing and therefore the components of the vehicle and the input variables of the useroriented design of the vehicle concept must be changed as well. We present a development process for autonomous vehicle concepts to address these challenges. We are therefore analyzing the current definition of a vehicle concept and its development process. Based on a literature review of a selection of common design methodologies, we update this definition for autonomous vehicle concepts and present a development process that presents design concepts of autonomous vehicle in a user need oriented way. This includes the sharing of models since user needs could be fulfilled by more than one vehicle concept. We believe that the presented process can be a starting point for vehicle concept development of the 21st century.
