Abstract
Information from sensors on first and second tires positioned adjacent to each other on a dual wheel hub is obtained and stored in a memory. Also, information about the operation of a vehicle is stored in the memory, where the first and second tires are located on the vehicle. A determination is made as to whether a tire radius difference exists between a first radius of the first tire and a second radius of the second tire based on the temperature values and other parameters. An indication is encoded for display that shows that a tire radius mismatch exists between the first and second tires.
Claims14
A system, comprising:
- at least one processor circuit with a memory comprising a plurality of instructions, wherein when executed by the processor circuit, the instructions cause the at least one processor circuit to at least:
- access a plurality of first temperature values of a first tire and a plurality of second temperature values of a second tire, the first tire being positioned adjacent to the second tire on a dual wheel hub;
- detect whether a tire radius difference exists between a first radius of the first tire and a second radius of the second tire based on the first and second temperature values;
- and
- encoding for display an indication that a tire radius mismatch exists between the first and second tires.
A system, comprising:
- at least one processor circuit with a memory comprising a plurality of instructions, wherein when executed by the processor circuit, the instructions cause the at least one processor circuit to at least:
- identify a time period in which a difference between a first radius of a first tire and a second radius of a second tire is known to be less than a maximum allowable difference threshold, the first and second tires being mounted on a dual wheel hub;
- identifying a segment of travel of the first and second tires occurring within the time period in which an amount of heat generated in the first and second tires due to a factor external to a free rotation of the first and second tires is substantially minimized;
- determining a first baseline temperature value for the first tire based on a plurality of first temperature values from the first tire, the first temperature values being generated during the segment of travel;
- and
- determining a second baseline temperature value for the second tire based on a plurality of second temperature values from the second tire, the second temperature values being generated during the segment of travel.
A system, comprising:
- at least one processor circuit with a memory comprising a plurality of instructions, wherein when executed by the processor circuit, the instructions cause the at least one processor circuit to at least:
- identify a time period in which a difference between a first radius of a first tire and a second radius of a second tire is known to be less than a maximum allowable difference threshold, the first and second tires being mounted on a dual wheel hub of a tractor;
- identifying a segment of travel of the first and second tires occurring within the time period in which an amount of heat generated in the first and second tires due to a factor external to a driven rotation of the first and second tires is substantially minimized;
- determining a first baseline temperature value for the first tire based on a plurality of first temperature values from the first tire, the first temperature values being generated during the segment of travel;
- and
- determining a second baseline temperature value for the second tire based on a plurality of second temperature values from the second tire, the second temperature values being generated during the segment of travel.
