Abstract: In a tire air pressure detection system, a trigger device is caused to transmit a notification trigger signal to notify wheel position detection in advance of outputting a detection trigger signal for signal magnitude measurement. After confirming reception of the notification trigger signal by a transceiver device, the trigger device is caused to transmit a detection trigger signal for wheel position detection. The detection trigger signal is transmitted after the transceiver device is set in a signal reception wait condition. The transceiver device is thus enabled to receive the detection trigger signal to measure a signal magnitude of the detection trigger signal.

Abstract: In a wheel identifying apparatus, first and second devices respectively transmit first and second trigger signals. The first device is mounted on the body of a vehicle closer to the front axle than the rear axle and closer to one of the front wheels than the other; it has the same height as the front axle and an orientation angle in a range of 0 to 90°. The second device is mounted on the vehicle body closer to the rear axle than the front axle and closer to one of the rear wheels than the other; it has the same height as the rear axle and an orientation angle in a range of 0 to 90°. Consequently, the first trigger signal can be reliably received by transceivers on the front wheels, and the second trigger signal can be reliably received by transceivers on the rear wheels.

Abstract: Four transceivers are attached to respective wheels of a vehicle. A pair of triggering devices transmit respectively different types of trigger signal, respectively directed toward the front wheels and toward the rear wheels. One triggering device is located closer to one rear wheel than to the other, while the other triggering device is located closer to one front wheel than to the other. Based on the received trigger signal type, a transceiver judges itself to be attached to either a front or a rear wheel, and based on the received trigger signal strength, judges whether it is attached to a right-side or left-side wheel.

Abstract: A tire location detecting apparatus for a vehicle with four wheels includes four rotation direction detecting devices, four transmitters, a triggering device, a receiver, and a controller. Each of the rotation direction detecting devices outputs a rotation direction signal which is then transmitted by an associated one of the transmitters. The triggering device triggers the transmitter on a first one of the four wheels to transmit an identification signal specific thereto. The receiver receives all of the signals transmitted from transmitters and provides those signals to the controller. The controller identifies the transmitter and tire on the first wheel based on the identification signal transmitted from the transmitter on the first wheel and determines, for each of the transmitters, whether the transmitter and the associated tire are located on one of the right-side wheels or one of the left-side wheels based on the rotation direction signal transmitted from the transmitter.

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: A tire condition detecting system has transmitters and a receiver. The transmitter is installed in a plurality of wheels and the receiver is installed in a chassis of a vehicle. The receiver has a controller which determines transmission timings in which a transmitting/receiving unit transmits the electrical wave for electrical charging to the transmitters. Moreover the controller detects an electrical wave from a nearby vehicle at the transmission timing. If the detected wave from the nearby vehicle is stronger, the controller waits for a predetermined period before making the transmitting/receiving unit transmit the electrical wave.

Abstract: A remote tire pressure monitoring system includes a tire monitor, a receiver, a transmitter, and a controller. The tire monitor is configured to operate in a power saving mode, in which it senses inflation pressure of a tire, determines a change in the inflation pressure of the tire, and transmits a pressure transmitting signal only when the determined change in the inflation pressure is greater than or equal to a predetermined threshold. The controller is operatively connected with the receiver and the transmitter. The controller works to determine, upon receipt of the pressure transmitting signal by the receiver, the inflation pressure of the tire based on the pressure transmitting signal. The controller also works to control, in response to receipt of the pressure transmitting signal by the receiver, the transmitter to transmit the acknowledge signal to inform the tire monitor that the receiver has certainly received the pressure transmitting signal.
