1 Profile of the Promoting virtual-drive testing for digital validation & verification Page 1

2 Motivation Connected and automated driving (CAD) Complex end-to-end system design and installed-performance evaluation Digital validation & verification indispensable Relies on co-operation between automotive OEM, wireless supply chain, network and telecom providers, test&design HW and SW houses, R&D institutions Key role of virtual drive tests for automation L3 Efficient and reliable testing with OTA/XiL approaches Co-existence and co-operation of multiple wireless and telematics services, ADAS DSRC/ITS-G5, C-V2X, 4G/5G/6G, Radar, GNSS, SOTM, DxB KPI for CAD system testing Reliable efficient scalable adaptable Extended digital control and use of virtual environment Open standards for virtual-drive test scenarios Page 2

3 Methodological approach to virtual drive testing PERFORMANCE METRICS Real traffic and radio environment Real test drives Dedicated test areas Channel sounding System level Link level Use cases (Critical) test scenarios Feature-based interpretation Statistical vs deterministic Static vs dynamic PERFORMANCE EVALUATION Virtual traffic and radio environment Channel emulation Over-the-air testing X-in-the-loop functionalities Modelling, abstraction, feature extraction Page 3

4 Objectives and implementation Key objectives 1. Identify use cases, technological gaps, and novel applications related to CAD 2. Evaluate potential and limitations of available standards (5G) and interoperability requirements with a technology-agnostic approach 3. Develop reliable and efficient CAD testing and conformity assessment towards digital approval, focusing on virtual drive testing with over-the-air and HiL approaches 4. Develop, adopt, and promote open accessible standards and specifications relating to virtual-drive tests Steps towards implementation Identify technology enablers and KPI for CAD system testing (automation levels L3) Creat common understanding of requirements for reliable and transparent evaluation methods for VDT Develop test methods and protocols for VDT as well as interoperability and certification tests suitable for adaptation by standard setting organizations Establish and promote VDT services and research Co-operate with other industry consortia and standard setting organizations Page 4

6 Technical Committees Lead questions TC1 System performance and connectivity TC2 Virtual-drive test design, emulation, and evaluation TC3 Dedicated HW and SW development and testing Cross-TC topics What to measure and to test? At which test levels (system level, link level, or component level)? Which scenarios and typical/extreme use cases? With which metrics for evaluating and validating test results? How to map the use and test cases onto virtual environments? How to emulate the test and use cases? Which steps to take towards standardisation? Which HW and SW for modelling/designing the emulation facilities? emulating the use and test cases? analysing and comparing the results? Test and use cases and test procedures Channels models and channel emulation Emulation facilities, hardware and software Page 6
