Ferrari F1 Team switches to driving simulator software from rFpro

Hertfordshire, UK, 13th Oct 2014... The renowned Ferrari F1 team is now using driving simulation software from specialist software company rFpro that models the world’s Grand Prix circuits with unprecedented levels of realism and response speed. The change was implemented following convincing results during extensive evaluation by Ferrari engineers.

Ferrari’s decision to change operational software, mid-season, underlines the scale of the performance improvement available because simulator downtime in F1 can mean costly interruption to the engineering development schedule. Ferrari already had a well-developed DIL (driver-in-the-loop) software solution in which they had invested significantly over a number of years, but the leap in performance was too great to ignore. “The trial of rFpro was so promising that we immediately put it to use in production-intent applications within our F1 team,” explained Ferrari’s Giacomo Tortora, responsible for Vehicle Dynamics.

To be fully effective as an engineering development tool for supplementing the limited track testing permitted in F1, simulation software must reproduce the track surface in minute detail and respond to dynamic inputs faster than the driver can detect. TerrainServer from rFpro is the first simulation package to fully satisfy both these requirements, and was selected after an exhaustive evaluation process.

"I think Ferrari’s tests are the most demanding faced by any vendor. We tested video bandwidth and latency, road surface data quality and visual accuracy for the digital circuit models,” said Tortora.

"It is important that the circuit model captures the road surface accurately, but also that it can be validated to ensure that our vehicle model is running on the same road surface as the real car,” he continued. "The way in which TerrainServer captures every LiDAR scanned data-point within the tyre contact patch, and integrates them all to provide our vehicle model with accurate road input, improves correlation with our measured data and also feels more realistic for the driver.”

To ensure the necessary level of track surface detail, rFpro uses LiDAR scanned data, reproducing surface features in 3D with an accuracy better than 1mm in Z (height) and 1cm in X and Y (position), representing a ten-fold improvement over the resolution previously available. In addition to its existing library of circuit data, rFpro can provide customers with turn-key solutions for scanning, modelling and providing high definition LiDAR data for other tracks, or even public road test routes.

Ferrari was equally demanding of the response speed, or latency, of the system, according to Tortora. "Video bandwidth is very important to us because we run multi-channel stereo projection and also wanted the fastest possible refresh rate,” he said. “rFpro are able to deliver the maximum video bandwidth, in stereo, at very high refresh rates with just a single frame of latency between our vehicle model and the projectors. This is the fastest solution on the market: video bandwidth is probably an order of magnitude greater than a traditional OpenGL based solution."

With most of the top F1 teams now using rFpro’s software, the company is turning its attention to the mainstream automotive industry, where the potential applications are even greater. The ability to simulate a vehicle’s dynamic behaviour accurately, with a driver in the loop, makes it feasible to assess extreme situations such as those encountered when testing ADAS systems, ESP and other control systems designed to affect the dynamic behaviour of the vehicle.
