Abstract
A system and method determine and/or adjust tire pressure sensor timings to transmit information using BLE information, regardless of the presence of other BLE systems. A tire pressure monitoring (TPM) system or other computing device receives transmission timing information from tire monitors that transmit using BLE and/or other BLE-enabled components. In response to determining an interference between the transmissions of the tire monitors and/or the components, timing of the transmissions from one or more of the tire monitors is altered to avoid the interference.
Claims20
A vehicle comprising:
- a plurality of tires;
- a first tire monitor associated with a first tire of the plurality of tires, the first tire monitor including a first pressure sensing component for generating first tire pressure data associated with the first tire and a first transmitter for transmitting the first tire pressure data using Bluetooth Low Energy (BLE);
- a second tire monitor associated with a second tire of the plurality of tires, the second tire monitor including a second pressure sensing component for generating second tire pressure data associated with the second tire and a second transmitter for transmitting the second tire pressure data using BLE;
- and
- a computing system configured to perform operations comprising:
- receiving first timing information associated with transmission of the first pressure data from the first tire monitor;
- receiving second timing information associated with transmission of the second pressure data from the second tire monitor;
- determining, based at least in part on the first timing information and the second timing information, a transmission interference;
- determining, based at least in part on the determining the transmission interference, adjusted timing parameters for at least one of the first tire monitor or the second tire monitor;
- and
- transmitting, to the at least one of the first tire monitor or the second tire monitor, a signal to cause the at least one of the first tire monitor or the second tire to adjust a timing associated with transmission of the first pressure data or transmission of the second pressure data according to the adjusted timing parameters.

A method comprising:
- receiving, via a BLE transmission and from a tire monitor on a vehicle, first timing information associated with transmission of pressure data generated by the tire monitor, the tire pressure monitor being configured to transmit the pressure data using BLE;
- receiving, from a computing device onboard the vehicle, second timing information associated with transmission of data from the computing device, the computing device being configured to transmit the data using BLE;
- determining, based at least in part on the first timing information and the second timing information, a potential transmission interference;
- and
- transmitting, to the tire monitor, a signal to cause the tire monitor to adjust timing associated with transmission of the pressure data, wherein the tire monitor is configured to adjust the timing.
