Abstract
A system is provided, the system including a tire disposed on a rim of a wheel, and an array of light-based sensors disposed circumferentially about the rim, where each light-based sensor of the array of light-based sensors directed toward the tire. The system includes a computing device which can receive one or more distance readings from the array of light-based sensors, generate a parabola approximating a contact area of the tire based at least in part on the one or more distance readings, approximate a shape of the contact area based at least in part on the parabola, and determine a static load estimation based at least in part on the shape of the contact area.
Claims20
A system, comprising:
- a tire disposed on a rim of a wheel;
- an array of light-based sensors disposed circumferentially about the rim, each light-based sensor of the array of light-based sensors directed toward the tire;
- a computing device comprising a processor and a memory;
- and
- machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:
- receive one or more distance readings from the array of light-based sensors;
- generate a parabola approximating a contact area of the tire based at least in part on the one or more distance readings;
- approximate a shape of the contact area based at least in part on the parabola;
- and
- determine a static load estimation based at least in part on the shape of the contact area.
A method, comprising:
- receiving, by a computing device, a plurality of distance readings from a plurality of distance sensors disposed around a rim of a tire;
- generating, by the computing device, an approximation of a contact area of the tire based at least in part on the one or more distance readings;
- and
- determining, by the computing device, a static load estimation based at least in part on the approximation of the contact area.
The method of claim , further comprising sending, by the computing device, a notification to a client device comprising the minimum number of distance sensors.
The method of claim , wherein determining a static load estimation, further comprises:
- determining, by the computing device, one or more regression parameters based at least in part on the tire;
- and
- calculating, by the computing device, the static load estimation based at least in part on the one or more regression parameters and based at least in part on the radial distance at the center point of the contact area.
A system, comprising:
- a tire disposed on a rim of the wheel;
- a computing device comprising a processor and a memory;
- and
- machine-readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:
- determine tire data corresponding to the tire;
- determine a minimum number of distance sensors needed to measure a load estimate based at least in part on the tire data;
- and
- send a notification to install at least the minimum number of distance sensors.
