At the Geneva Motor Show, The Goodyear Tire & Rubber Company introduced two concept tires designed with autonomous driving in mind. The future-oriented spherical Eagle-360 was designed with key features of maneuverability, connectivity and biomimicry for autonomous mobility; the IntelliGrip, featuring advanced sensor and treadwear technology, is a solution for the earlier adoption of self-driving vehicles.
Both tires are designed with safety in mind, which according to recent studies, is a key concern among consumers around autonomous vehicles.
Eagle 360. The multi-orientation of the spherical Eagle-360 tire 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.
Embedded sensors further increase safety by communicating road and weather conditions to the vehicle control system and other nearby cars, while tread and tire pressure monitoring technology regulate even wear of the 360-degree tire to extend mileage.
The tires would rely on a magnetic levitation system to suspend the car resulting in a smooth, quiet ride for the passenger.
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 tire is designed to communicate with autonomous vehicle control systems, sensing road surface and weather conditions for improved driving safety and performance. When the tire senses a rainy or slippery road surface, the autonomous vehicle will adapt its speed. Additionally, the tire can shorten the stopping distance, provide a better cornering response, optimize stability and even support collision prevention systems.
With advanced sensor technology and specially designed tread, the concept tire can sense many road conditions, including both surface and weather conditions.
The IntelliGrip also uses advanced active wear technology to assess the condition of the tire and the vehicle.
Goodyear-developed algorithms account for variables such as inflation pressure and tire temperature.
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.
