The invention discloses an intelligent tire capable of automatically stretching out and drawing back anti-skid nails and a control method of the intelligent tire. The tire comprises a rim, a main tire, an auxiliary tire, an electromagnetic air valve, a thin film electric generator and an exhaust pipe; the main tire is arranged on the rim, and an annular groove is formed in the center of the outer wall of the main tire; the auxiliary tire is arranged in the annular groove, and a plurality of anti-skid nails are evenly arranged on the outer wall of the auxiliary tire in the circumferential direction; a through hole is formed in the bottom wall of the annular groove; a through hole for the exhaust pipe to extend out is formed in the rim; the electromagnetic air valve adopts a three-position three-way valve, and three connecting ports are respectively communicated with a cavity in the auxiliary tire, a cavity in the main tire and the outside; and the thin film electric generator is adhered to the inner wall of the main tire and is electrically connected with the electromagnetic air valve. The anti-skid nails can be controlled to stretch out or retract, the road holding force of the tire is greatly improved when the anti-skid nails stretch out, and the driving stability of a vehicle on low-adhesion-coefficient road surfaces such as mire, grassland and snowfield is remarkably improved; and during retraction, the anti-skid nails can be prevented from being abraded and the road surface is protected.

    本发明公开了一种可自动伸缩防滑钉的智能轮胎及其控制方法,轮胎包含轮辋、主胎、副胎、电磁空气阀、薄膜发电机和排气管;主胎设置在在轮辋上,其外壁中心设有环形凹槽;副胎设置在环形凹槽内,其外壁上周向均匀设有若干防滑钉;环形凹槽的底壁上设有通孔;轮辋上设有供排气管伸出的通孔;电磁空气阀采用三位三通阀,三个连接口分别联通至副胎内的腔体、主胎内的腔体、外界;薄膜发电机粘贴在主胎的内壁上、和电磁空气阀电气相连。本发明能够控制防滑钉伸出或缩入,伸出时大大提高轮胎抓地力,显著提升车辆在泥沼、草地、雪地等低附着系数路面上的行驶稳定性;缩入时能够防止防滑钉磨损同时保护路面。
