APART from the 3D printed rubber ball that Goodyear presented as a future tyre for self-driving cars at the Geneva International Motor Show, the spherical, the company also showed its IntelliGrip­ tyre.

This wheel packs advanced sensor technology in the rubber to support current and autonomous vehicle control systems.

According to a study from the World Economic Forum, cities expect autonomous vehicles to become a reality in the next 10 years [1]. In addition, the J.D. Power 2015 U.S. Tech Choice Study [2] concludes that consumers deem collision protection technology most important in the wake of the changing automotive industry.

“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.

“The concept tyres play a dual role in the future both as creative platforms to push the boundaries of conventional thinking and as test beds for next-generation technologies.”

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

The IntelliGrip also uses advanced active wear technology, based on Goodyear’s active wear and tyre-pressure monitoring system sensor technology, to assess the state of the tyre and the vehicle.

Goodyear developed special algorithms to account for such variables as inflation pressure and tyre temperature to give a better estimation of the state of the tyre and as a result, optimise the autonomous control system of the vehicle.

In addition to sensing the road and tyre conditions, the tyre also communicates with the vehicle’s central computer system, which should contribute to delivering improved driving performance and safety.

When the tyre senses a rainy or slippery road surface, the autonomous cornering response optimise stability and even support collision prevention systems.

Goodyear is working with a number of car 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.

The IntelliGrip’s microchip was developed with Huf, a leading manufacturer of mechanical and electrical locking systems, tyre pressure monitoring systems and telematic systems for the automotive industry worldwide.
