US 2026/0084472 A1 · AUTO-LOCATION OF TIRE MONITORS

Abstract

Systems and methods of tire monitor auto location are disclosed. A tire pressure monitoring system generates output signals to communicate with tire monitors mounted on tires of a vehicle. Times associated with return signals responsive to the output signals are used to determine a distance of the tire monitors and/or an angular displacement of the tire monitors. Using these techniques, monitors may be located without the need for vehicle operation. In other examples, accelerometers and/or contact patch measurements can be used to auto-locate tire monitors, e.g., while the vehicle is in operation.

Dependent claims

A tire monitor configured for coupling to a tire of a vehicle in at least a first orientation or a second orientation, the tire monitor comprising:

an accelerometer configured to generate acceleration data;
a sensor configured to generate sensor data associated with an area of contact of the tire with a road surface;
and
a computing system configured to perform operations comprising:
determining, based at least in part on the acceleration data, that the tire monitor is mounted in an orientation comprising the first orientation or the second orientation;
determining, based at least in part on the orientation and the sensor data, that the tire is coupled to a front axle of the vehicle or that the tire is coupled to a rear axle of the vehicle;
and
determining, based at least in part on the orientation and the sensor data, that the tire is coupled to a left side of the vehicle or that the tire is coupled to a right side of the vehicle.
