Device for transmitting measurements of a sensor to a central unit
First Claim
1. A method of transmitting measurements from a sensor to a central unit by a wireless link, such as a radio link for example, in a motor vehicle or similar, characterized in that it comprises the following steps:
- detection of the stopped state of the vehicle (2), measurement by the sensor of a parameter such as pressure (6) for example, storage of the result of the measurement within the sensor (10), analysis, at the level of the sensor, of the measurement with reference to the preceding measurements (8), storage of the significant results of the analysis within the sensor (10), and when the vehicle is moving again, transmission (14) by the sensor, if necessary, to the central unit of significant data on the events that have occurred since the last detected stoppage of the vehicle;

Abstract
The method is carried out in a vehicle or similar, comprising the following steps: detection of the state of the vehicle (2) when stopped, the sensor measures a parameter such as pressure (6), the result of the measurement is stored in the sensor (10), the sensor analyses the measurement according to previous measurements (8), significant results of the analysis are stored inside the sensor (10), and when the vehicle begins once more to travel, significant data relating to events occurring since the last detected stop of the vehicle is transmitted (14) from the sensor to the central unit wherever applicable.
