Goodyear and Gatik demonstrate capability to estimate tire-road friction potential accurately for automated driving
07 January 2023
In an important step towards safer and more sustainable goods movement through autonomous transportation, Goodyear and Gatik (earlier post) have demonstrated, in a proof-of-concept, that intelligent tires powered by Goodyear SightLine technology can accurately estimate tire-road friction potential and provide real-time information to Gatik’s automated driving system (ADS).
The capability will add more utility to what a tire can deliver by providing critical data that can help enhance vehicle safety and performance, increasing efficiency and value for Gatik’s customers in the B2B short-haul market.
Friction estimates from Goodyear’s SightLine solution were successfully able to detect low grip conditions, such as snowy or icy conditions, and make this information available to Gatik’s autonomous fleet.
Goodyear and Gatik recently deployed road-friction detection capabilities in Canada through continuous measurement of tire sensor-derived information, which is paired with other vehicle data and connected to Goodyear’s cloud-based proprietary algorithms to optimize vehicle performance.
Friction estimates from Goodyear’s SightLine solution were successfully able to detect low grip conditions, such as snowy or icy conditions, and make this information available to Gatik’s autonomous fleet, enhancing safety and performance for Gatik’s commercial operations in Canada’s challenging winter climate.
With road-friction data, tires can help enable smoother, safer and more sustainable driving. This is critical information for autonomous vehicles in terms of path planning and providing recommendations for safe driving speed, vehicle acceleration limits and vehicle following distance.
Goodyear SightLine technology is designed to measure the tire wear state, load, inflation pressure and temperature. It combines that with real-time road-weather data and proprietary rubber friction models to estimate the tire-road friction potential.
Having this information in real-time enables Gatik’s fleet to respond safely and efficiently to challenging conditions within its operational design domain (ODD). While Goodyear’s SightLine technology has tremendous future implications for autonomous driving, this year it is anticipated that Goodyear will also be deploying Goodyear SightLine technology on select original equipment vehicles bringing immediate utility to today’s mobility market.
The tire is the only part of the vehicle that touches the ground, and this new level of data sophistication can communicate vital information to the vehicle, enhancing safety and performance. This is another step to evolve the tire to not only deliver its core, traditional job but also be a nexus of new data and information.—Chris Helsel, Goodyear’s senior vice president, Global Operations and Chief Technology Officer
