Abstract

A tire pressure adjusting system of a vehicle includes: a sensor mounted in a tire, to measure pressure and/or temperature of air in the tire, and to send a signal corresponding to the pressure and/or temperature; a magnetic field generator mounted on the vehicle body near the tire, to receive the signal from the sensor, and to generate a magnetic field; a current generator mounted in the tire, to generate electricity by using the magnetic field; and an electric heating member mounted in the tire, to generate heat by using the electricity supplied from the current generator, thereby heating the air in the tire. A method of controlling tire pressure includes determining whether the pressure is too low; and, if the pressure is too low, heating air in the tire until the pressure is not too low.

Claims

1. A tire pressure adjusting system of a vehicle, comprising:

a sensor configured to be mounted in a tire, to measure at least one of pressure and temperature of air in the tire, and to send a signal corresponding to the pressure and/or temperature;

a magnetic field generator configured to be mounted on a vehicle body near the tire, to receive the signal from the sensor, and to generate a magnetic field;

a current generator configured to be mounted in the tire and to generate electricity by using the magnetic field; and

an electric heating member configured to be mounted in the tire and to generate heat by using the electricity supplied from the current generator, thereby heating the air in the tire.

2. A method of controlling a tire pressure, the method comprising:

determining whether a pressure in a tire is too low; and

if the pressure is too low, heating air in the tire until the pressure is not too low.

3. The method of claim 2, wherein the heating comprises generating a magnetic field in a magnetic field generator, thereby generating electricity in a current generator;

and supplying the electricity to an electric heating member.

4. The method of claim 2, further comprising informing a user that the pressure is being controlled, during the heating step.
