摘要： An apparatus for detecting motion of a wheel comprising tyre. The apparatus comprises a pressure sensor for measuring the tyre pressure and generating a signal corresponding to the measured tyre pressure, and means for detecting a component of said signal that corresponds to, or is generated by, vibrations of the tyre. Upon detection of the signal component, the apparatus determines that the wheel is in motion. The detecting means may arranged to detect an audio signal component or signal components having a frequency in the range 200 Hz to 300 Hz.

摘要： A wheel monitoring system that includes a tracking filter apparatus for tracking a signal that has a varying main frequency. The tracking filter apparatus has an adjustable filter and a filter controller arranged to measure the amplitude of the filtered signal and to compare amplitude against a reference value. The filter controller adjusts the cut off frequency of the filter if the measured amplitude differs from the reference value by an amount that exceeds a threshold value. The filter controller adjusts the cut off frequency such that the main frequency lies within the roll off region of the filter's frequency response. The system may be used to track signals that are produced by shock sensors in a wheel mounted monitoring device.

摘要： A method carried out in a wheel unit of a tire pressure monitoring system comprises detecting, using a controller in the wheel unit, increases and decreases in loading of a tire on a wheel associated with the wheel unit during acceleration and deceleration. Front/rear position of the wheel unit on a vehicle mounting the tire pressure monitoring system is determined, using the controller in the wheel unit, based on the loading and unloading of the tire and wheel during acceleration and deceleration. Rotation direction of the wheel in the wheel unit is determined and the controller in the wheel unit determines left/right position of the wheel unit on the vehicle based on the rotation direction of the wheel. An indication of the front/rear and left/right position of the wheel on the vehicle and an identification unique to the transmitting wheel unit are transmitted.

摘要： A tire pressure detector employs a reduced power consumption mechanism comprising a PLL circuit including a VCO, that is operated in response to the logic states of an input data stream and a power amplifier configured to be externally located to an integrated circuit. The input data stream includes tire pressure information and is configured to be encoded to have multiple logic states. A micro-controller is employed to control the VCO, turning the VCO, and/or the amplifier, on and off for a certain period, according to the pattern of each data bit of the input data stream thus providing reduced current consumption. This tire pressure detector thus embodies an optimized circuit arrangement in terms of power efficiency.
