Abstract
Method and apparatus are disclosed for monitoring tires of vehicles via personal area networks. An example vehicle includes a body, nodes spaced apart on the body, a tire, a transceiver coupled to the tire, and a tire detector. The tire detector is to determine a tire position based on wireless communication between the transceiver and the nodes, identify a duration that the tire is at the tire position, and present a warning to rotate the tire position when the duration is greater than a predetermined threshold.
Claims18
A vehicle comprising:
- a body;
- a gyroscope;
- a speed sensor;
- nodes;
- a tire:
- a transceiver coupled to the tire;
- a GPS receiver to identify a vehicle location;
- a camera to monitor vehicle surroundings;
- and
- a tire detector to:
- determine a tire position based on wireless communication between the transceiver and the nodes;
- identify a duration that the tire is at the tire position;
- present a warning for tire rotation when the duration exceeds a threshold;
- reduce the threshold upon detecting a sharp turn via the gyroscope and the speed sensor;
- determine whether the tire is decoupled from the body based on the wireless communication between the transceiver and the nodes;
- present a second warning when the tire is decoupled from the body;
- and
- adjust a rate at which the nodes broadcast beacons for the transceiver based on the vehicle location and the vehicle surroundings to facilitate monitoring for decoupling of the vehicle.
A method, performed by a processor, comprising:
- determining a position of a tire based on wireless communication between a tire transceiver and nodes spaced apart on a vehicle body;
- identifying a duration of the tire at the position;
- presenting a warning for tire rotation when the duration exceeds a threshold;
- monitoring turns via a gyroscope and a speed sensor;
- and
- reducing the threshold based on detection of a sharp turn and on a tire pressure measured by a pressure sensor.
A vehicle comprising:
- a gyroscope;
- a speed sensor;
- nodes;
- a tire;
- a tire pressure sensor to measure a tire pressure of the tire;
- a transceiver coupled to the tire;
- and
- a tire detector to:
- determine a tire position based on wireless communication between the transceiver and the nodes;
- identify a duration that the tire is at the tire position;
- present a warning for tire rotation when the duration exceeds a threshold and further based on a tire pressure measurement;
- and
- reduce the threshold upon detecting a sharp turn via the gyroscope and the speed sensor and in response to determining, via the tire pressure sensor, that the tire is overinflated.
