Tire pressure monitoring system communication method and system

A method to facilitate secure communication between a first tire pressure monitoring system (TPMS) and a vehicle, wherein the method comprising:

• obtaining, by an electronic control unit (ECU) of the vehicle, a trigger signal to auto-locate the first TPMS from a plurality of TPMSs, wherein the first TPMS is configured to monitor a vehicle tire condition;
• obtaining, by the ECU, learning mode advertisements from each TPMS of the plurality of TPMSs responsive to obtaining the trigger signal, wherein the learning mode advertisements comprises a random value and a test value associated with each TPMS, and wherein the test value is an encrypted value generated using TPMS keys;
• calculating, by the ECU, a vehicle test value using the random value and a vehicle pre-shared key;
• comparing, by the ECU, the obtained test value with the calculated vehicle test value;
• auto-locating, by the ECU, the first TPMS when the obtained test value associated with the first TPMS matches with the calculated vehicle test value;
• and
• receiving, by the ECU, vehicle tire condition data from the first TPMS responsive to auto-locating the first TPMS.

A non-transitory computer-readable storage medium in a distributed computing system, the non-transitory computer-readable storage medium having instructions stored thereupon which, when executed by a processor, cause the processor to:

• obtain a trigger signal to auto-locate a first tire pressure monitoring system (TPMS), from a plurality of TPMSs, wherein the first TPMS is configured to monitor a vehicle tire condition of a vehicle;
• obtain learning mode advertisements from each TPMS of the plurality of TPMSs responsive to obtaining the trigger signal, wherein the learning mode advertisements comprises a random value and a test value associated with each TPMS, and wherein the test value is an encrypted value generated using TPMS keys;
• calculate a vehicle test value using the random value and a vehicle pre-shared key;
• compare the obtained test value with the calculated vehicle test value;
• auto-locate the first TPMS when the test value associated with the first TPMS matches with the vehicle test value;
• and
• receive vehicle tire condition data from the first TPMS responsive to auto-locating the first TPMS.
