Adaptive Tire Treads for Changing Road & Environmental Conditions

Tire with adjustable tread pattern to improve traction and stability on different road conditions. The tire has a tread with multiple blocks that can deform in response to road conditions. Sensors detect the road surface and independently control deformation of the inner and outer blocks. During cornering, blocks protrude to increase grip. This adaptive tread design aims to optimize traction and stability based on real-time road conditions.

Controllable wheel for vehicles that can adjust the depth of the tire tread patterns. The wheel has an electric push rod inside the tire cavity that extends radially to move the outer tread block. This allows the tread depth to be changed electronically to adapt the tire for different terrain without swapping wheels. The push rod connects to an electric contact ring on the hub, which in turn connects to a telescopic link on the vehicle frame. A spring keeps the link retracted, but when the vehicle needs deeper tread, the link extends the push rod to push the tread block further. This allows electronic adjustment of the tread depth on the fly.

A system that optimizes vehicle control systems like ABS and CMBS using real-time tire sensor data. The system involves mounting sensors on vehicle tires to measure parameters like pressure, temperature, wear, etc. An adaptive tire model processes this data to continuously generate revisions to tire-specific performance parameters like braking stiffness, optimal slip point, and shape factor. These revisions are then applied in real-time to the vehicle control systems to optimize their performance based on the current tire state. This provides predictive knowledge of tire braking capability for improved ABS robustness and CMBS safety.

Adaptive tire technology for vehicles that can change tire shape based on driving conditions to optimize performance. The tires have shape-changing agents integrated into the wall that can be electronically controlled. Sensors detect driving situations like acceleration, braking, cornering, and straight-ahead travel. The shape-changing agents are activated to modify the tire footprint for better traction, stability, and wear in those conditions. This allows customized tire performance for specific driving scenarios beyond just tire tread design.

A tire with adjustable tread depth and pattern that can be automatically or manually changed based on weather or road conditions. The tire has a system to vary the groove depth and tread design on one tire to optimize traction for specific conditions. Sensors detect the environment and controls adjust the tread properties accordingly. This allows the driver to quickly adapt the tire performance to match external factors. It provides customized tire characteristics for enhanced safety and grip in varying conditions.

Vehicle tire with integrated actuators to dynamically adjust tire properties like stiffness, shape, and dimensions in response to driving conditions. The actuators are made of shape memory materials like carbon nanotubes and nanofibers that expand or contract when electrically charged. These actuators are embedded within the tire's elastic matrix material. Sensors on the vehicle provide data to dynamically control the actuators and adapt the tire properties for optimized performance and safety in different driving scenarios.

A pneumatic tire design that can adapt the width of the tread blocks' cuffs based on road conditions to optimize traction and handling. Piezoelectric elements are installed between adjacent cuffs. Applying power to these elements deforms them, widening the cuffs for snow/ice roads and narrowing them for dry roads. This allows maintaining appropriate block rigidity for the conditions.
