Method for monitoring the pressure in a wheel tire and monitoring system
First Claim
1. A method for monitoring pressure in a tire of a wheel of a motor vehicle, the motor vehicle comprising a sensor module generating a signal indicative of a momentary pressure value in the tire, the motor vehicle also comprising a transmission module and a reception module for transmitting information of the momentary pressure value in the tire to a management module, the management module being capable of receiving and processing the information supplied, the management module including a first predetermined pressure value corresponding to a higher vehicle speed value, and the management module including a second predetermined pressure value corresponding to a lower vehicle speed value, the first predetermined pressure value being greater than the second predetermined pressure value, the monitoring method comprising:
- comparing the momentary pressure value with a target pressure value, the target pressure value corresponding either to the first predetermined pressure value or to the second predetermined pressure value;
choosing the first predetermined pressure value as target pressure value when the momentary pressure is too low relative to the second predetermined pressure value; and
choosing the second predetermined pressure value as target pressure value when the momentary pressure is too high relative to the first predetermined pressure value.

Abstract
A sensor module generates a momentary tire pressure signal, and a transmitting module transmits the momentary pressure information. A management module receives and processes the information and includes a first predetermined pressure value corresponding to a higher speed for the vehicle, and a second predetermined pressure value corresponding to a lower speed, the first predetermined pressure value being greater than the second predetermined pressure value. The method includes comparing the momentary pressure value to a target pressure value, the target pressure value corresponding to either the first predetermined pressure value or the second predetermined pressure value, selecting the first predetermined pressure value as the target pressure value when the momentary pressure is too low relative to the second predetermined pressure value, and selecting the second predetermined pressure value as the target pressure value when the momentary pressure is too high relative to the first predetermined pressure value.

7. A system for monitoring pressure in a tire of a wheel of a motor vehicle, the monitoring system comprising a sensor module generating a signal indicative of a momentary pressure value in the tire, the monitoring system also comprising a transmission module and a reception module for transmitting information of the momentary pressure value in the tire to a management module, the management module being capable of receiving and processing the information supplied, the management module including a first predetermined pressure value corresponding to a higher vehicle speed value, and the management module including a second predetermined pressure value corresponding to a lower vehicle speed value, the first predetermined pressure value being greater than the second predetermined pressure value, the system being designed such that the target pressure value corresponds either to the first predetermined pressure value or to the second predetermined pressure value, and that a choice of the first predetermined pressure value as target pressure value is made when the momentary pressure is too low relative to the second predetermined pressure value, and that the choice of the second predetermined pressure value as target pressure value is made when the momentary pressure is too high relative to the first predetermined pressure value.
