Integrated system and method for tire pressure monitoring and remote keyless entry

An integrated system for tire pressure monitoring and remote keyless entry applied to a vehicle and a key fob (30) sending a wireless signal at a predetermined carrier frequency, the system comprising:

• an in-vehicle integrated controller (10) located within the vehicle and comprising a central controller unit (100) and a central wireless transceiver (110) electrically connected to the central controller unit (100);
• and
• at least one tire pressure monitoring module (20) located at a vehicle tire and comprising a tire pressure processing unit (200), a tire pressure wireless transceiver (210) and a tire pressure sensor (220), wherein the pressure processing unit (200) is electrically connected to the tire pressure wireless transceiver (210) and the tire pressure sensor (220), and the tire pressure wireless transceiver (210) is operated at the predetermined carrier frequency;
• wherein the in-vehicle integrated controller (10) is configured to send a tire information request signal to the tire pressure monitoring module (20) when the in-vehicle integrated controller (10) receives and authenticates an unlocked request from the key fob (30);
• wherein the tire pressure monitoring module (20) is configured to send a tire information signal containing at least a tire pressure data within a predetermined time threshold after the tire pressure monitoring module (20) receives the tire information request signal.
