摘要： A tire pressure monitor provided on a wheel of a vehicle includes a pressure sensor, a transmitter, an acceleration sensor, and a controller. The pressure sensor works to output a pressure signal representative of the inflation pressure of a tire fitted on the wheel. The transmitter works to transmit the pressure signal. The acceleration sensor works to output an acceleration signal representative of a centrifugal acceleration which increases with the running speed of the vehicle. The controller is configured to: 1) determine a change in the centrifugal acceleration for a predetermined time period based on the acceleration signal, 2) determine the vehicle as being in running state when the determined change is greater than or equal to a predetermined threshold, and 3) control the transmitter to transmit the pressure signal when the vehicle is determined as being in running state.

摘要： 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.

摘要： 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.

摘要： A tire inflation pressure sensing apparatus according to the present invention includes a transmitter, a receiver, and a command signal receiver. The transmitter is provided on a wheel of a vehicle and includes a pressure sensor configured to sense the inflation pressure of a tire on the wheel and generate a pressure signal indicative of the sensed inflation pressure. The receiver is provided on the body of the vehicle and works to receive the pressure signal and determine the inflation pressure of the tire based on the pressure signal. The command signal receiver is operatively connected to the transmitter and works to receive command signals that indicate instructions for the transmitter. The command signal receiver has a variable receiver sensitivity so as to prevent the command signal receiver and transmitter from being activated by noises while ensuring reliable activation of the command signal receiver and transmitter by “true” command signals.

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.
