1. 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.

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.

12. 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. - View Dependent Claims (13, 14, 15)

16. 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. - View Dependent Claims (17, 18)
