System for controlling a vehicle wheel tyre pressure
First Claim
1. A system for checking the pressure of the tires of wheels of a motor vehicle, comprising:
- a control unit,on each wheel, a pressure sensor and an emitter in order to transmit to the control unit a pressure signal comprising data for identification of the sensor, andmeans for determining the speeds of rotation of the wheels, in order to associate the pressure signal the wheel of the corresponding sensor,wherein the means for determining the speeds of rotation of the wheels comprises means for comparison of data of speeds of rotation of the wheel, determined in different manners.

Abstract
The system comprises a control unit (17), and, on each wheel, a pressure sensor (12) and an emitter (13) in order to transmit to the control unit (17) a pressure signal comprising data for identification of the sensor, and means (17) for determination of the speeds of rotation of the wheels, in order to associate (174,179) with each pressure signal the wheel of the corresponding sensor (12), and which comprise means (179) for comparison of data of speeds of rotation of the wheel, determined in different manners (34,50), by the periods (Ti) of the envelopes for modulation of the signals emitted by the emitters (13) and by the wheel anti-blocking device (20).
