摘要: L'invention concerne un dispositif de mesure la vitesse rotation d'une roue vehicule, le comportant corps (22) dans lequel sont integres : The invention relates to a device for measuring the speed of vehicle wheel, comprising body into which are integrated: - rotor (30) pouvant etre entraine en par et sur est monte au moins aimant permanent (33) ; A drivable in by wheel and on is mounted at least one magnet (33); stator (31) bobinage (36) generant une tension lorsque (2) donc l'aimant tournent, etant representative having coil generating voltage measurement when therefore rotated, being rotational speed; carte electronique (32) des moyens traitement An electronic card means processing measurement; d'alimentation adaptes generer partir destinee alimenter electronique. Supply adapted generate from supply powering card. Des d'adaptation destines abaisser ou relever d'alimentation, si celle-ci superieure inferieure seuil predetermine. adaptation raise or lower voltage, if it greater less than predetermined threshold. Ces peuvent comporter convertisseur type Buck-Boost. These may comprise Buck-Boost converter.
