摘要： A batteryless tire inflation pressure detecting apparatus includes, on the body of a vehicle, antennas and a transmitter transmitting radio waves through the antennas. The apparatus also includes, on each wheel of the vehicle, a pressure sensor sensing the pressure of a tire, a transceiver, and a charging unit powering the pressure sensor and the transceiver. The charging unit is charged with electric power induced by a corresponding one of the radio waves received by the transceiver. The apparatus further includes, on the body of the vehicle, a receiver receiving pressure signals transmitted by the transceivers, a pressure determiner determining the pressures of the tires based on the pressure signals, and a controller. To minimize influence of the radio waves on neighboring devices, the controller controls the transmitter so that least two of the radio waves are transmitted at different times, or at the same with a phase difference therebetween.

摘要： In a vehicle tire air pressure detection system, a charging electromagnetic wave is transmitted for a predetermined period from a vehicle chassis side and stored as a charge voltage in a transmitter unit attached to a tire wheel. When the charge voltage reaches a predetermined level, a sensor in the transmitter unit detects a tire air pressure and a transmitter/receiver of the transmitter unit transmits a detection data on an electromagnetic wave in the same frequency band as the charging electromagnetic wave after the predetermined period from a time point at which the charge voltage has reached the predetermined level. Thus, interference between the charging electromagnetic wave and the electromagnetic wave of the detection data is prevented.

摘要： A tire inflation pressure detecting apparatus includes a second transceiver provided on the body of a vehicle which changes its operation alternately between a second transmitter and a second receiver mode, thereby intermittently transmitting a radio wave. A first transceiver provided on a wheel of the vehicle operates in a first receiver mode to receive the radio wave, thereby charging a charging unit. When the charging unit has been sufficiently charged, the first transceiver changes operation thereof from the first receiver mode to a first transmitter mode, in which the first transceiver first repeatedly transmits an informing signal at predetermined time intervals for a predetermined time period and then transmits a pressure signal. When the informing signal is received by the second transceiver in the second receiver mode, the second transceiver keeps its operation in the second receiver mode until the pressure signal is completely received.
