Abstract

A method for combining tire pressure monitoring with keyless entry, is applied in a vehicle (10) and a remote controller (20), the vehicle (10) includes a vehicle radio frequency transceiver unit (106), an engine (102), a vehicle door lock (104) and a tire (110). The tire (110) includes a tire radio frequency transceiver unit (112) and a tire pressure sensor unit (114). The tire radio frequency transceiver unit (112) transmits a tire pressure information signal (S3). The method including the steps of: transmitting a keyless entry radio frequency signal (S1) via the remote controller (20); receiving the keyless entry radio frequency signal (S1) via the vehicle radio frequency transceiver unit (106), and unlocking the vehicle door lock (104); starting the vehicle (10); and changing an emitting cycle of the tire pressure information signal (S3) transmitted by the tire radio frequency transceiver unit (112) into a first cycle.

Claims

1. A method for combining tire pressure monitoring with keyless entry, is applied in a vehicle (10) and a remote controller (20), the vehicle (10) comprises a vehicle radio frequency transceiver unit (106), an engine (102), at least one vehicle door lock (104) and at least one tire (110), the tire (110) comprises a tire radio frequency transceiver unit (112) and a tire pressure sensor unit (114), after the tire pressure sensor unit (114) monitors a pressure of the tire (110), the tire radio frequency transceiver unit (112) transmits a tire pressure information signal (S3), the method for combining tire pressure monitoring with keyless entry comprising the steps of:

transmitting a keyless entry radio frequency signal (S1) via the remote controller (20);

receiving the keyless entry radio frequency signal (S1) via the vehicle radio frequency transceiver unit (106), and unlocking the vehicle door lock (104);

starting the vehicle (10); and

changing an emitting cycle of the tire pressure information signal (S3) transmitted by the tire radio frequency transceiver unit (112) into a first cycle.

2. The method for combining tire pressure monitoring with keyless entry according to claim 1, wherein after the step of changing an emitting cycle of the tire pressure information signal (S3) transmitted by the tire radio frequency transceiver unit (112) into a first cycle, the method further comprising a step of changing the emitting cycle of the tire pressure information signal (S3) transmitted by the tire radio frequency transceiver unit (112) into a second cycle after the engine (102) is stopped, and the first cycle is shorter than or equal to the second cycle.

3. The method for combining tire pressure monitoring with keyless entry according to claim 2, wherein the first cycle is once every ten seconds, and the second cycle is once every twenty minutes.
