Development of a computer platform for visualisation and simulation of vehicular DC distribution systems

“…Algorithm 1 summarises the implemented BFS strategy. However, a detailed explanation can be found in [9] (Fig. 5).…”

“…In the automotive industry, there is a systematic process to create a file container having all the possible electrical configurations for a particular car model [9]. This container has an extensible mark‐up language extension (.xml) and it was mainly designed for automotive industries and suppliers to share manufacturing data.…”

“…To address the aforesaid challenges, in previous work from the authors, the automobile wiring design process, the required manufacturing data preprocessing, and a detailed methodology to perform power flow analysis were presented [9]. Also, in the context of vehicular EDS simulation, the main contributions of this work deal with the aspects of software development, user interface, and visualisation.…”

Web-Based Simulation Environment for Vehicular Electrical Networks

“…The latest simulation trends in automotive systems deal with advanced functionalities such as scalable models for autonomous-driving cars [3], energy-efficient networking for electric vehicles networks [4] and internet of vehicles for automation and orchestration [5]. However, regarding the on-board Electrical Distribution Systems (EDS), which are responsible for delivering power supply to the different consumers within a vehicle, only few commercial tools (such as Harness Studio and Saber RD) and a few sustained research related to tailored simulation platforms have been exposed [2,6,7]. Vehicular EDS (in blue color in Figure 1) are intricate networks composed of a vast number of protections, splices, couplings, Electronic Control Units (ECUs) and loads that are interconnected with several wire harnesses enclosing thousands of cables, representing up to 3 km of cabling [7].…”

“…To cope these challenges and permit vehicle design engineers an early detection of unsuitable configurations, such as those leading to undesired voltage drops, excessive temperatures or mistaken components sizing, the development of versatile simulation methods and platforms is compelling. In this respect, recent research has proposed frameworks to perform EDS power flow simulations considering the specific data format employed in the automotive industry and using algorithms based on backward/forward sweep [6] and current-injections methods [8]. In [2], the relevancy to include Visual Analytics tactics in EDS simulation environments is highlighted to facilitate human-data interaction.…”
