Abstract
A system and method are described for determining the shape of at least part of a tyre. The system has a plurality of radio-reflective objects associated with the tyre; one or more wheel-mounted radar sensors configured to receive radio waves reflected from each of the plurality of radio-reflective objects; and processing circuitry to: determine a position of each of the plurality of radio-reflective objects based on a corresponding radar measurement made by the one or more wheel-mounted radar sensors; and determine the shape of at least part of the tyre based on the determined positions.
Claims15
A system for determining the shape of at least part of a tyre, the system comprising:
- a plurality of radio-reflective objects associated with the tyre;
- one or more wheel-mounted radar sensors configured to receive radio waves reflected from each of the plurality of radio-reflective objects;
- and
- processing circuitry configured to:
- determine a position of each of the plurality of radio-reflective objects based on a corresponding radar measurement made by the one or more wheel-mounted radar sensors;
- and
- determine the shape of at least part of the tyre based on the determined positions.
A method for determining the shape of at least part of a tyre, the method comprising:
- receiving, by one or more wheel-mounted radar sensors, radio waves reflected from each of a plurality of radio-reflective objects associated with the tyre;
- determining, by processing circuitry of a computer system, a position of each of the plurality of radio-reflective objects based on a corresponding radar measurement by the one or more wheel-mounted radar sensors;
- and
- determining, by the processing circuitry, the shape of at least part of the tyre based on the determined position.
A computer system for determining the shape of at least part of a tyre, the computer system comprising processing circuitry configured to:
- receive a radar measurement corresponding to each of a plurality of radio-reflective objects associated with the tyre from one or more wheel-mounted radar sensors;
- determine a position of each of the plurality of radio-reflective objects based on a corresponding radar measurement by the one or more wheel-mounted radar sensors;
- and
- determine the shape of at least part of the tyre based on the determined position.
A computer-implemented method for determining the shape of at least part of a tyre, the computer-implemented method comprising:
- receiving, by processing circuitry of a computer system, a radar measurement corresponding to each of a plurality of radio-reflective objects associated with the tyre from one or more wheel-mounted radar sensors;
- determining, by the processing circuitry, a position of each of the plurality of radio-reflective objects based on a corresponding radar measurement by the one or more wheel-mounted radar sensors;
- and
- determining, by the processing circuitry, the shape of at least part of the tyre based on the determined position.
