rFpro and cosin scientific software partner to enable simulation of a physically accurate road and tyre model

Jan 29, 2020   Technology

Leading tyre simulation specialists cosin scientific software can now run their physical tyre model FTire with rFpro, the industry experts in driving simulation software and digital twins.

Using an ultra-high resolution road model with a physically accurate tyre model in real-time, significantly improves the accuracy of data and therefore correlation with real world results. The physics-based tyre model spans primary and secondary ride allowing it to be used in a variety of circumstances, including extended handling maneuver and active safety application scenarios. Traditionally, OEMs, Tier 1 suppliers, and AI focused businesses have used lightweight Pacejka or extended Magic Formula style tire models, which are not able to cover the short wave-lengths effects coming from road surface irregularities.


Prof. Dr. Michael Gipser, Co-Founder of cosin scientific software, explainsed, “Coupling FTire simulation with the state-of-the-art virtual worlds that rFpro produces, means that customers can in greater detail replicate real-world driving conditions with complete confidence. Previously, the tyre simulations capable of running sufficiently fast to work in an rFpro environment have been less accurate models. FTire is incredibly efficient in its ability to deliver physics-based simulation, even whilst running fast enough for real-time applications within rFpro’s digital twins." 


Enabling FTire to be used with rFpro now allows the same model to be used throughout the entire tool chain and the whole development process across all departments, from the office, HiL (Hardware-in-the-Loop) testing, through to driving simulator systems.


With FTire, rFpro experiments running on HPC data centres, HiL test rigs and driving simulators can benefit from tire contact patches that react realistically to the detailed road surface in rFpro's environments. Crucially, this means that experiments will correlate more closely with real-world tests at proving grounds, particularly in the way the car's motion affects the orientation of ADAS sensors mounted around the vehicle.


Matt Daley, Managing Director, rFpro, added, “We also have customers generating terabytes of simulated training data. There are many use cases where it is important to simulate the vibrations of the sensor platform mounted on a vehicle that is driving on rough road surfaces. This new capability will extend the validity of simulated training data, saving even more time and money for our customers, compared to traditional video and photography data sets.” 


Detailed simulated vehicles heave and pitch realistically over rFpro’s high accurate modeled digital twins of urban city centres, highways and proving grounds. rFpro's highly precise environments for driving simulation are trusted by the world’s leading proving ground owners. They deliver high quality digital twins of the owners’ facilities to vehicle manufacturers and their suppliers to accelerate testing in simulation.
