Connected and Shared X-in-the-Loop Technologies for Electric Vehicle Design

Abstract

The presented paper introduces a new methodology of experimental testing procedures required by the complex systems of electric vehicles (EV). This methodology is based on real-time connection of test setups and platforms, which may be situated in different geographical locations, belong to various cyber-physical domains, and are united in a global X-in-the-loop (XIL) experimental environment. The proposed concept, called XILforEV, allows exploring interdependencies between various physical processes that can be identified or investigated in the process of EV development. The paper discusses the following relevant topics: global XILforEV architecture; realization of required high-confidence models using dynamic data driven application systems (DDDAS) and multi fidelity models (MFM) approaches; and formulation of case studies to illustrate XILforEV applications.

Innovative e-machine and power electronics solutions for e-axle and e-corner vehicle powertrains

“…The methodology will be characterised by: i) agile model based XiL methods integrated into the standard V-model of the system development lifecycle; ii) adaptive interfaces for coupling virtual and physical systems from different domains and process holders; iii) extension of the XiL concept by real-time networking complex testing facilities in different geographical locations, which enables co-verification and co-validation involving multiple partners. The approach is an advancement of established procedures [16] through the integration of network-and internet-based complex testing facilities for realtime cooperative experiments.…”

Geographically distributed real-time co-simulation of electric vehicle

“…those points and it is built using the XILforEV framework [2] [3], which creates a distributed X-In-Loop environment (XIL) merging SIL, MIL, HIL, and TRIL for electric vehicles. The environment connects test platforms and setups from different physical domains placed at different locations.…”

Component-in-the-Loop Testing of Automotive Powertrains Featuring All-Wheel-Drive

“…With the expansion of powertrain functionality, the traditional techniques of bench testing became insufficient as they only allowed simulating simple driving modes (i.e., linear motion with no tire-road adhesion taken into account). The improvement of functionality of laboratory testing has come in the form of the component-in-the-loop (CiL) technology being a part of the wide variety of X-in-the-Loop methods [6][7][8] (where X stands for either a hardware or a software system). CiL combines the hardware components that are physically presented in the laboratory and software models of the physically absent components, as well as the environment, into a cohesive system existing partly in the physical and partly in the virtual domain.…”
