ABSTRACT:
A tire status monitoring system monitors tire conditions, such as tire pressure, temperature, etc., thereby improving automobile safety. The tire status monitoring system provides transmitters, mounted within the vehicle tires, for transmitting tire conditions. A receiver is installed in the vehicle, for analyzing the tire condition data received from each transmitter. The transmitter includes a pressure sensor for sensing air pressure, a temperature sensor for sensing temperature in the tire; a drive detecting sensor for sensing driving velocity; a radio transmission module for modulating the input data into a radio frequency signal to transmit the modulated signal; and a control device for identifying the operation mode by the pressure, temperature and driving velocityinput from the sensors in sensing mode. The control device controls the radio transmission module so that the sensed data can be transmitted at a predetermined period according to the identified operation mode.
