US 12,611,896 B2 · Tire monitoring sensor powered by wireless power, system and control method thereof, and vehicle having the same

Abstract

The present disclosure relates to a tire monitoring sensor, a system and a method for controlling the same. The system according to an embodiment of the present disclosure is provided in a vehicle, and may include: a tire monitoring sensor (TMS) comprising a battery and mounted on a tire or wheel of the vehicle, and detecting a condition of the tire; and a main transceiver provided at a position spaced apart from the TMS in the vehicle. The main transceiver comprises a plurality of coils configured to generate first magnetic fields by application of an alternating current. The plurality of coils is disposed such that the first magnetic fields are applied to the TMS sequentially according to a rotation of the tire or the wheel. The alternating current is applied to the plurality of coils such that adjacent first magnetic fields have opposite phases.
