This Special Issue reports on the current status of research concerning vehicle design processes. Designing vehicles is one of the most challenging tasks in engineering for several reasons. Considerable consumer expectations and intense global competition complicate vehicle design. Currently, dramatic changes are influencing vehicle design, mainly caused by the transition to electric drive systems and new vehicle application scenarios, especially in the Asian market. Cost-driven design is a necessity, and vehicles must be economical in terms of production, operation, and recycling. Sustainable design is also imperative in order to achieve ecological vehicles. The dynamics of vehicles must be considered in the design of all components, and lightweight design is of fundamental importance. Consumers expect convincing functional performance, high product quality, an appealing appearance, high reliability, interconnected functionality, and comprehensible and appealing user interfaces. Vehicles are expected to provide more and more additional services, also in connection with external service providers. These colossal requirements lead to complex multi-domain vehicle design processes because most of the important decisions are made in the design phase. Production optimization and intelligent operation are important topics, but flaws and insufficiencies in the design stage lead to considerable expenditure in later stages and suboptimal products. The design processes of vehicles involve thousands of engineers, who are spread out across the globe and need to consider multiple product versions and variants as well as multi-company product platforms. Testing necessities and legal issues frequently play an important role in these processes, and the economic and ecological quality of a product must be monitored throughout these processes. Vehicle safety and ergonomic quality must be considered even in the early stages. Naturally, only digital support makes these processes feasible. For all domains, powerful computer tools for synthesis, analysis, evaluation, and optimization have been created, and numerous attempts have been made to sensibly link the data used in all these tools. However, the multitude of domain-specific and generic data formats and the sheer size of the data still cause serious problems. Importantly, design is also connected with scheduling and project management because certain design decisions can lead to long-term testing and production preparation processes. In recent years, research teams worldwide have proposed novel, expanded, and improved approaches, which may support, enhance, and streamline vehicle design processes. The promising approaches concentrate on the abstract levels of product modelling—especially the function level [1] and the level of abstract physics [2]. Leading companies in the field of vehicle development and production have made a shift from document-based process management to model-based systems engineering (MBSE), and several research groups have contributed to this transition [3–5]. A central scientific field in this context is the automation of design processes. Graph-based design languages (GBDLs) constitute an important example; they have led to a paradigm shift in design processes, enabling the integration of data, information, and knowledge into product and systems models and fostering design automation [6–8]. Another central scientific field emphasizes the expansion of the established design-for-X guidelines. Important examples are fault-tolerant design (FTD) [9], design for sustainability [10], and design for resilience [11]. Another promising field is the integration of control and diagnosis capabilities in vehicle components, focusing on smoother, more efficient operation and increased fault tolerance [12]. Several research groups have focused on the establishment of a full-scope digital twin of a vehicle that allows bi-directional interaction in real time and covers all the life-cycle stages of a vehicle [13]. Another set of approaches aims at the integration of artificial intelligence (AI) in design, assembly, and production processes [14,15]. The listed challenges and the multitude of approaches concerning the multi-domain design processes of vehicles have led to a prominent need for research aimed at supporting design engineers in this endeavor. This Special Issue presents a collection of research in this area.
