Method of development of a virtual copy of a test route suitable for virtual testing

Abstract

Introduction (problem statement and relevance). Today, computer simulation plays an important role in testing and development of new systems, especially in the field of highly automated vehicles (HAV). Virtual testing becomes an integral part of this process, given the current safety issues. With the use of modern technologies such as high-precision satellite navigation and high-quality aerial photography, it has now become possible to make accurate and exact virtual copies of road sections.The purpose of the study is to develop a method to make a virtual copy of a road suitable for virtual testing on improvement of energy efficiency of connected HAV.Methodology and research methods. A natural experiment based on the use of the high-precision navigation system in the vehicle provided the basis for making such virtual copy, which can be used to optimize HAV movement in order to improve HAV energy efficiency.Scientific novelty and results. The developed map was checked for compliance with the mapping standards and was assessed for accuracy. The scientific novelty of this method is making 3D virtual copies of road sections with the use of high-precision navigation including RTK corrections and aerial photography. The resulting virtual model of the road section is ready for solving a wide range of tasks related to optimizing HAV movement and improving HAV energy efficiency.Practical significance. This approach can have promising applications not only in the automotive industry, but also in other areas such as urban design, planning, logistics and ecology, where efficient traffic management is critical for sustainable development
