Embodiment Construction

[0056] Figure 4 A functional diagram of the system for monitoring tire 1 pressure of the present invention is shown. It includes a pressure sensor 7, a pressure change sensor 2, as described below. A management module 3 is provided, which is combined with the sensor 2 electrically or mechanically. The battery 4 enables power to be supplied to the module 3 and the sensor 7, and optionally to the sensor 2, but the preferred type of sensor 2 of the present invention does not require any power, enabling savings on the battery 4. In order to enable the transmission of data from the vehicle's wheels to the vehicle, a transmission module 5 is preferably provided. For example, a transmitter (preferably HF (high frequency)), and a transponder etc. may be included. Antenna 6 can optionally be mounted on Figure 4 installation.

[0057] This device is provided for mounting on a wheel, either a rim or a tyre. It may also be incorporated into one or the other of these components, fo...

Abstract

The invention concerns a system for measuring pressure and for controlling inflation / deflation of a tyre comprising: a pressure sensor, a pressure variation sensor capable of reacting in a safety time interval to a substantially significant and quick pressure variation inside the tyre cavity, and of interacting with another element co-operating with said sensor; a management module, capable of receiving and processing data supplied by the pressure sensor and capable, on the basis of the information provided by the variation sensor, of controlling 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.

Description

technical field [0001] The invention relates to a tire pressure measurement and inflation / deflation control system. Background technique [0002] Car and tire manufacturers are constantly working harder to heed the growing demands of modern road users for safety, comfort and convenience. This phenomenon is clearly evident from the usual features of various devices that have not been seen in fact for only a few years, such as airbags, ABS (anti-lock braking system) brakes, ESP devices, and the like. [0003] More recently, tire pressure measuring and / or monitoring devices have come into use. Improvements to safety, fuel consumption and tire life are made by simply, reliably and frequently informing drivers of how inflated their vehicle's tires are. These systems generally include at least one tire pressure sensor known per se. [0004] Thus, for example, certain types of pressure sensors are known, such as capacitive or resistive types, enabling the pressure of a tire to b...
