Abstract
Disclosed are various approaches for optimizing tire performance by automatically inflating or deflating the tire based on a measured footprint length. A sensor affixed to a tire can measure a footprint length in real-time. If the measured footprint length is outside a target footprint length range, the tire may need to be inflated or deflated. Accordingly, an instruction can be sent to an automatic tire inflation system of the vehicle instructing the automatic tire inflation system to inflate or deflate the tire. Once a subsequent measurement of the footprint length is within the target range, the automatic tire inflation system can be instructed to stop inflating the tire.
Claims20
A system for optimizing tire performance, the system comprising:
- a sensor affixed to an innerliner of a tire of a vehicle;
- an automatic tire inflation system coupled to the tire;
- a computing device comprising a processor and a memory, the sensor and the automatic tire inflation system being communicatively coupled to the computing device;
- and
- machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:
- determine a footprint length of the tire based at least in part on sensor data obtained from the sensor;
- compare the footprint length with a target footprint length range;
- and
- send an instruction to the automatic tire inflation system to initiate inflating or deflating the tire in an instance in which the footprint length is outside the target footprint length range.
A method for optimizing tire performance, comprising:
- obtaining, via a vehicle computing device, sensor data from a sensor affixed to an innerliner of a vehicle;
- determining, via the vehicle computing device, footprint length of a tire of a vehicle based at least in part on the sensor data;
- comparing, via the vehicle computing device, the footprint length with a target footprint length range;
- and
- sending, via the vehicle computing device, an instruction to an automatic tire inflation system of the vehicle to initiate inflating or deflating the tire in an instance in which the footprint length is outside the target footprint length range.
