Sen­sor pack­ing rubber

New tyres sense road sur­face and talk to car’s com­puter

APART from the 3D printed rubber ball that Goodyear pre­sented as a fu­ture tyre for self­driv­ing 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 testbeds 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, opti- mise 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. —
