Abstract: According to the present invention, a tire pressure monitor, which is 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.

Abstract: A transmitter device includes a rotational direction sensor that generates a specific pattern signal when a corresponding tire rotates. The pattern signal of the left tires is different from the pattern signal of the right tires. A front reception antenna is near the front tires. A rear reception antenna is near the rear tires. A receiver includes a switch circuit that selectively connects the front reception antenna or the rear reception antenna to a controller. When one transmitter device transmits a radio signal, the controller determines which transmitter device is the source of the radio signal in accordance with the level of the signals from the reception antennas and the pattern signal, which is included in the data transmitted by the transmitter device.

Abstract: A method and system for monitoring air pressure or operational status of at least one particular tire of a vehicle facilitates ready identification of a relative mounting position of the particular tire. At least one pressure indicating signal is received (110 of FIG. 8) and is associated with a particular tire mounted at an unknown relative position on a vehicle. Physical parameter data are obtained (112) indicating physical parameter measurements at the different tires of a vehicle. The obtained physical parameter data are evaluated (114) to identify the relative mounting position of the particular tire on the vehicle. Accordingly, an operator of the vehicle may be provided with an indication (130) that an air pressure of a particular tire is less than a proper air pressure so that peak vehicle performance and necessary maintenance may be obtained. Even if the indication informs that the pressure is normal, the operator is reassured that the tires are functioning properly.

Abstract: A method for operating a monitoring device for at least one vehicle parameter, in particular an air-pressure sensor for the tire-pressure vehicle parameter. The monitoring device is operated in a drive mode or in a stationary mode as a function of the velocity of the vehicle. Connection signals for the wireless connection to an external device, in particular a configuration device for the monitoring device, are transmitted in the stationary mode. Prior to the change to the stationary mode, the monitoring device is operated in a first intermediate mode. A passive search for wireless connection signals from the external device is carried out in the first intermediate mode.

Abstract: A reception control section obtains a rotation angle of each wheel assembly when a reception circuit receives transmission data. The reception control section calculates the absolute value of the difference between the obtained rotation angle and a previously obtained rotation angle. The reception control section determines whether the absolute value of the difference is included in a reference range or a specific range. The reference range includes 0. The specific range includes the angle difference between specific angles.

Abstract: In a method for controlling a processor on a wheel, wheel operation parameters are calculated and transmitted to a CPU. A first default operating mode (standby mode) is defined, during which activities related to calculating and checking the characteristic data of the tread mark of the tire are deactivated, a second operating mode for detection of significant changes in the value of a characteristic datum of the tread mark, sought during the appearance, in standby mode, of at least one event likely to be preceded by a significant change in the value, and a third operating mode for calculation and transmission, to a CPU, a sequence of values representing the characteristic datum of the footprint, sought during the confirmation, in detection mode, of a significant change in the value of the characteristic datum of the tread mark, and at the end of which a switch is made into monitoring mode.

Abstract: A self-adaptive method for assisting tire inflation enables control of tire inflation. If the vehicle stops, the central unit of a TPMS (Tire Pressure Monitoring System) can change in a self-adaptive manner from the reception configuration of the “moving” mode at a high bit rate to a “stationary” mode at a low bit rate. At the same time, if there is a variation in the pressure of a tire, the corresponding wheel unit is set for transmission in “stationary” mode at a low bit rate. The power Pa received at the central unit varies according to a curve (20) which shows, in the illustrated example, two positions of poor reception. By replacing high bit rate transmission with low bit rate transmission, the signal/noise ratio is improved and there is a gain in reception sensitivity of about 5 dB, and the risks of disturbance of the received power are virtually eliminated.

Abstract: Method for transmitting a radio signal between a moving electronics unit of a wheel and a fixed central electronic control unit of the vehicle, includes: defining an angular reference point of the wheel; defining a division of one wheel revolution into successive basic sectors, and transmitting successive radio signals between the two units so that each signal is transmitted at a calculated predetermined wheel angular position; calculating the angular rotation speed of the wheel; determining a minimum wheel rotation sector required for the transmission time of a signal between the two units, at the calculated angular rotation speed; determining an angular offset of transmission between a first and a second following signal, with respect to the angular reference point, as being equal to the smallest multiple of the basic division sector which covers the time required for transmission of the first radio signal at the calculated angular rotation speed.
