Summary:

India has seen a significant boost in automotive research and development, specific to Vehicle Dynamics active safety systems and ADAS. To develop these systems, without excessive reliance on full working prototypes, vehicle manufacturers are relying on virtual models to better fine tune the design parameters. For this, there is a real requirement of digital twins of the proving grounds. This virtual testing surfaces will help in reducing test costs, test times and increase iteration counts, leading to fine-tuned prototype vehicle and finally a market leading product. National Automotive Test Tracks (NATRAX) is already playing a crucial role in the testing and development of these technologies, on its test tracks. Recognizing the need to assist in virtual testing for Indian automotive manufacturers, NATRAX is taking steps to develop virtual proving grounds to complement physical testing and reduce the development time. This paper targets a comparative analysis of dynamic parameters between virtual track testing and actual track testing on a virtual representation of durability road surface. The surface is created by taking co-ordinates of road profiles after a particular interval and by making a collection of more than 21,000 values, this combination of location and road roughness creates exact replica of NATRAX test track. The aim of this study is to identify and bridge the gap between results from physical durability testing and virtual durability testing, using the virtual proving ground. For the study, the parameters identified will be compared between the virtual testing and equivalent physical testing to establish a correlation under specified conditions, leading to newer avenues in India to advance the usage of virtual proving ground for development of vehicle dynamics and ADAS systems
