Abstract: A pressure measuring and inflation/deflation control system for tires, comprising: a pressure sensor, a pressure variation detector capable on the one hand of responding in a safety time interval to a substantially significant and rapid variation in the pressure inside the cavity of the tire, and on the other hand of acting on another element cooperating with said detector; a management module, capable of receiving and processing informations provided by the pressure sensor on the one hand and on the other hand by the pressure variation detector and capable, on the basis of the information provided by the pressure variation detector, of actuating the shift from a so-called “normal” pressure measuring mode to a so-called “accelerated” measuring mode, or the shift from the “accelerated” mode to the “normal” mode.

Abstract: System for monitoring the tires of a vehicle, comprising a device for automatic location of a radio transmitter, comprising a first radio reception channel having a first aerial and a second radio reception channel having a second aerial, the first and second aerials defining an axis D1, a first means of comparison of the phases of a radio signal received by the first and second aerials in order to determine whether the radio signal received by the first aerial is ahead of phase, behind phase or has an identical phase relative to the radio signal received by the second aerial and a means of processing the results originating from the first means of comparison intended to indicate the position of the radio transmitter relative to the said aerials.

Abstract: A device for detecting substantially sudden and significant loss of pressure in a tire, comprising: a pressure variation detector capable on the one hand of responding in a safety time interval to a substantially significant and rapid variation in the pressure inside the tire cavity, and on the other hand of acting on another element cooperating with said detector; a management module, cooperating with said detector and capable, on the basis of the information supplied by said detector, of sending a signal when a given pressure variation threshold is reached.

Abstract: A tire pressure monitoring system, comprising: a pressure measuring sensor in fluid communication with the ambient pressure of the tire; a noise detector, adapted to detect the noise produced by the vehicle when it is started; a management module, adapted to receive and process data supplied by the pressure sensor on the one hand and on the other hand by the noise detector such that, when the vehicle is stopped, the pressure sensor operates in “economy” mode; when the vehicle is running, the pressure sensor operates in “normal” mode.

Abstract: A safety insert comprising a substantially circumferential base intended to come into contact with an adapted wheel rim, a substantially circumferential body intended to support a tread of a tire mounted on the rim during rolling with a pressure capable of causing at least partial flattening of a portion of the tire, and a housing intended to receive a wheel unit, characterized in that the safety insert comprises an aerial which is rigidly connected to the insert and is disposed inside its volume.

Abstract: A method for verifying the compatibility of the components of a wheel, having the following steps of: identifying each of the components of the assembly by means of an electronic label; after mounting the assembly, verifying at least two of these labels by checking the mutual compatibility of the components corresponding to the identification elements received by a management unit; detecting any situation in which at least one of the components is incompatible with one or more of the other components, and generating a suitable signal in the event of incompatibility. The invention also relates to a device for carrying out this method, this device comprising an identification element combined with each of the components of the assembly that it is desired to verify, a data transmission means, the management unit being capable of identifying any condition of incompatibility of at least one of the components of an assembly and of generating a signal in the event of a condition of incompatibility.
