Abstract
(DE)
Verfahren zur Zustandserkennung eines Fahrzeugreifens (2) und/oder einer Fahrbahn (8), wobei mindestens ein im Reifeninneren (10) angeordneter Sensor (3), insbesondere ein Beschleunigungssensor, ein Signal erzeugt, das physikalischen Größen des Fahrzeugreifens (2) und/oder der Fahrbahn (8) zugeordnet ist. Anhand des Signals wird ein Reifenzustand und/oder Eigenschaften der Fahrbahn (8) ermittelt.
(EN)
The invention relates to a method for identifying the condition of a vehicle tyre (2) and/or a roadway (8). According to said method, at least one sensor (3) that is located in the interior of the tyre (10), in particular an acceleration sensor, generates a signal that is assigned to physical variables of the vehicle tyre (2) and/or roadway (8). The signal is used to determine the condition of the tyre and/or characteristics of the roadway (8).
(FR)
L'invention concerne un procédé de détection de l'état d'un pneu de véhicule (2) et/ou d'une chaussée (8), au moins un capteur (3) placé à l'intérieur (10) du pneu, en particulier un capteur d'accélération, générant un signal associé à des grandeurs physiques du pneu de véhicule (2) et/ou de la chaussée (8). Un état du pneu et/ou des propriétés de la chaussée (8) sont déterminés à partir dudit signal.
