Abstract
Disclosed are examples for detecting a displacement of a sensor within a tire. A baseline signal strength is compared to a measured signal strength. When a calculated comparison value (e.g., delta standard deviation) meets or exceeds a threshold value, the sensor is determined to be displaced from the expected location in the tire. When a sensor is determined to be displaced or otherwise loose from the expected location within the tire, an alert can be generated to provide notice to the vehicle driver or other entity of the issue so that the issue can then be remedied.
Claims20
An apparatus, comprising:
- at least one computing device comprising a processor and a memory;
- and
- at least one application executable on the at least one computing device, wherein when executed, the at least one application causes the at least one computing device to at least:
- determine a measured signal strength associated with a sensor unit of a tire on a vehicle;
- compare the measured signal strength with a baseline signal strength;
- and
- determine that the sensor unit is detached from an expected location on an innerliner of the tire based at least in part on the comparison of the measured signal strength and the baseline signal strength.
A method, comprising:
- determining a baseline signal strength associated with a sensor unit attached to a tire of a vehicle;
- determining a measured signal strength associated with the sensor unit over a period of cycles;
- comparing the measured signal strength with the baseline signal strength;
- and
- detecting an issue with a placement of the sensor unit based at least in part on the comparison of the measured signal strength with the baseline signal strength.
A loose sensor detection system for identifying a loose sensor within a tire, the loose sensor detection system comprising:
- a sensor unit disposed within an inner surface of the tire;
- at least one computing device in data communication with the sensor unit;
- and
- at least one application executable by the at least one computing device, wherein, when executed, the at least one application causes the at least one computing device to at least:
- obtain sensor parameter data collected from the sensor unit;
- measure a signal strength associated with the sensor unit based at least in part on an analysis of the sensor parameter data;
- compare the measured signal strength with a baseline signal strength;
- detect an issue with a placement of the sensor unit within the inner surface of the tire based at least in part on the comparison of the measured signal strength and the baseline signal strength;
- and
- generate an alert indicating the issue with the placement of the sensor.
