Snow Traction Enhancement for Winter Tires

A specialized traction enhancement system for vehicles stuck on low-friction surfaces like ice, snow, mud, or sand. The system uses flexible strips with unique features like adhesive gripping elements, progressive elevation segments, and self-deploying connectors to automatically insert and position under tires. This allows the strips to self-feed into place using the wheel rotation, providing traction without needing precise placement or external force. The strips also have sensors to transmit weight distribution data.

Tire tread pattern with enhanced 3-level sipe geometry that improves dry performance while maintaining wet/snow traction throughout the tire's life. The sipe design has two key features: interference profiles and contact surfaces. The interference profiles are steps within the sipe that prevent full contact between adjacent sipe edges when the tire is new. This reduces stiffness and improves grip on wet/snow. As the sipe wears, the steps wear down allowing full contact for improved dry performance without sacrificing wet/snow traction. The contact surfaces are areas within the sipe that are meant to contact the ground during rolling. These provide additional voids in the tread for improved wet/snow grip as the sipe wears. The combination of interference profiles and contact surfaces allows optimized performance on both dry and wet/snow surfaces by compensating for void reduction during tire wear.

Controlling the differential locking function of a vehicle like a farming tractor to improve traction on slippery terrain. The method involves detecting wheel slip, calculating the slip based on actual and acceptable wheel speeds, and tracking the trajectory where slip exceeded acceptance. This allows identifying areas where the ground conditions reduced traction. The differential can then be unlocked in those areas to prevent wheelspin. After leaving the slippery section, the differential can lock again for normal driving.
