SYSTEM AND METHOD FOR COMBINATION CONTROLLING SMART KEY AND WHEEL UNIT OF TIRE PRESSURE MONITORING SYSTEM

摘要

PURPOSE: A smart key and a tire air pressure sensing wheel unit-integrated control system are provided to simplify the complicated wiring of a vehicle by preventing a transceiver from being duplicatively used in the communication between the smart key and a tire air pressure sensing unit. CONSTITUTION: A tire air pressure sensing wheel unit-integrated control system comprises a smart key(500), a tire air pressure sensing unit(300) and an integrated controller(100). The smart key wirelessly can open a door. The tire air pressure sensing wheel unit senses the pressure and temperature of a tire. The integrated controller wirelessly communicates with the tire air pressure sensing wheel unit in the first operation mode according to an operation mode signal and wirelessly communicates with the smart key in the second operation mode. The integrated controller comprises a transmitter(110) and a receiver(120). The transmitter wirelessly transmits a tire air pressure sensing wheel control signal in the first operation mod and a smart key control signal in the second operation mode. The receiver wirelessly receives an information signal corresponding to the tire air pressure sensing wheel control signal in the first operation mod and a response signal to the smart key control signal in the second operation mode.
