Abstract: According to the invention, a wheel identifying apparatus includes a plurality of transmitters and a receiver. Each of the transmitters is mounted on one of wheels of a vehicle with a given distance from a rotation axis of the wheel. Each of the transmitters is configured to transmit a signal when an angular position thereof coincides with a predetermined angular position. The receiver includes a receiving antenna located at such a predetermined position on a body of the vehicle that all distances from the receiving antenna to the rotation axes of the wheels of the vehicle are different from each other. The receiver works to receive all the signals transmitted from the transmitters, detect the received signal levels of the signals, and identify, for each of the signals, the wheel on which the transmitter having transmitted the signal is located, based on the detected received signal level of the signal.

Abstract: 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.

Abstract: A receiver includes an antenna, an impedance-matching circuit, a receive circuit, a control circuit, a digital-to-analog (D/A) converter, a mode switch, and an EEPROM. The impedance-matching circuit includes a variable-capacitance diode. The control circuit determines an operation mode set by the mode switch. It controls the D/A converter to produce different levels of the reverse bias voltage when the operation mode is set to an adjustment mode. It determines strength of receive signals based on receive signal strength indication (RSSI) signals indicating strength of the receive signals. It determines a maximum value of the RSSI signals based on the results of the determination, and stores D/A input data corresponding to the maximum value in the EEPROM as the adjustment data. It loads the adjustment data from the EEPROM and controls the D/A converter to produce a reverse bias voltage based on the adjustment data. The D/A converter applies the voltage to the variable-capacitance diode.

Abstract: A sensor detects values of inflation pressure of a tire of a vehicle one after another. A controller calculates, from the values of the tire inflation pressure, a deflation rate at which the tire is deflating per unit time. When the deflation rate is higher than a first predetermined value, the controller judges that the tire is suddenly punctuated. When the deflation rate is not higher than the first predetermined value but is higher than a second predetermined value, the controller judges that the tire is deteriorated. When the deflation rate is not higher than the second predetermined value, the controller judges that compressed air is naturally leaked from the tire. An alarm unit gives an alarm indicating punctuation or deterioration of the tire or natural air leaking in response to the judgment of the controller.

Abstract: In a vehicle's wheel position detecting apparatus, plural transceivers respectively attached to the front and rear four wheels are provided. Each transceiver receives a triggering signal, calculates a reception intensity of the triggering signal, stores data indicating the reception intensity into a frame, and transmits the frame to a receiver attached to a vehicle's body. Each triggering signal radio-transmitted from the first and second triggering devices contains a startup command to starts up each transceiver and an execution command to allow each transceiver to calculate the reception intensity. The first and second triggering devices, which are responsible for radio-transmitting the triggering signal toward at least the front wheels and the rear wheels respectively, are positionally offset to either way in the body's lateral direction. A receiver receives the frames and uses the frames radio-transmitted from the transceivers to detect the wheels' positions using the reception intensity in each frame.

Abstract: In a vehicle's wheel position detecting apparatus, a first triggering device, attached to the vehicle's body, outputs a triggering signal including information indicating that the triggering signal is for front wheels. A second trigging device, attached to the body, outputs a triggering signal including information indicating that the triggering signal is for rear wheels. The first and second triggering devices output the triggering signals simultaneously. A transceiver is attached to each of the front and rear four wheels. Each transceiver receives the triggering signal, calculates a reception intensity of the triggering signal, stores both the reception intensity data and the information into a frame, and transmits the frame. A receiver, attached to the body, receives the frame and processes the received frame to read out both the data and the information and use the read-out data and information to detect the positions of the wheels.
