Goodyear reveals concept tyres for autonomous cars

03 March 2016

Goodyear Tyre & Rubber Company revealed two concept tyres at the 86th Geneva International Motor Show that could reshape autonomous cars.

The concepts: the spherical-shaped Eagle-360 - a future-oriented tyre - was designed with key features of maneuverability, connectivity and biomimicry for autonomous mobility, while the IntelliGrip, featuring advanced sensor and treadwear technology, is a solution for the earlier adoption of self-driving vehicles.

Both tyres are designed with safety in mind, which according to recent studies, is a key concern among consumers around autonomous vehicles. They reflect Goodyear’s focus on anticipating the rapidly evolving needs of its customers.

“By steadily reducing the driver interaction and intervention in self-driving vehicles, tyres will play an even more important role as the primary link to the road,” said Joseph Zekoski, Goodyear’s senior vice president and chief technical officer. “Goodyear’s concept tyres play a dual role in that future both as creative platforms to push the boundaries of conventional thinking and testbeds for next-generation technologies.”

Additional details on the two concept tyres:

Goodyear Eagle-360

The Goodyear Eagle-360 is a spherical-shaped design concept tyre that would provide self-driving cars ultimate maneuverability, connectivity and biomimicry to increase safety.

• Maneuverability: The multi-orientation of the spherical-shaped tyre allows the car to move in all directions, contributing to safety for passengers, as well as coping with space limitations such as tight parking lots or city streets.

• Connectivity: Embedded sensors further increase safety by communicating road and weather conditions to the vehicle control system and other nearby cars, while tread and tyre pressure monitoring technology regulate even wear of the 360-degree tyre to extend mileage.

• Connected via magnetic levitation: The tyres would rely on a magnetic levitation system to suspend the car resulting in a smooth, quiet ride for the passenger.

• Biomimicry: Inspired by nature, the 3D printed tread mimics the pattern of brain coral and behaves like a natural sponge – designed to stiffen in dry conditions and soften when wet to deliver excellent driving performance and aquaplaning resistance.

Goodyear IntelliGrip

The Goodyear IntelliGrip concept tyre is designed to communicate with autonomous vehicle control systems, sensing road surface and weather conditions for improved driving safety and performance.

• Senses road conditions: Thanks to its advanced sensor technology and specially designed tread, the concept tyre can sense many road conditions, including both surface and weather conditions.

• Active-wear technology: The IntelliGrip also uses advanced active wear technology to assess the condition of the tyre and the vehicle.

• Custom algorithms: Goodyear-developed algorithms account for variables such as inflation pressure and tyre temperature.

• Adapting to road conditions: When the tyre senses a rainy or slippery road surface, the autonomous vehicle will adapt its speed. Additionally, the tyre can shorten the stopping distance, provide a better cornering response, optimise stability and even support collision prevention systems.

• Technology adaption: Goodyear is working with a number of vehicle manufacturers to further adapt this technology to their needs, enhancing connectivity with features such as Electronic Stability Control Systems, Brake Control Systems and Suspension Control Systems.

Although these tyres are future concepts, Zekoski says they represent an essential aspect of Goodyear’s innovation strategy and its vision for smart and safe mobility.
