Abstract

L’invention concerne un procédé et un dispositif de contrôle de l’alimentation de calculateurs (13, 14) d’un véhicule. A cet effet, un signal électrique déterminé est appliqué en entrée d’un ou plusieurs superviseurs d’alimentation (11, 12). Le signal électrique déterminé est également appliqué en entrée d’un ou plusieurs convertisseurs analogiques numériques, dit CAN (15 à 18). Ce signal électrique déterminé possède des caractéristiques déterminées permettant de tester si le superviseur d’alimentation (11, 12) détecte correctement une surtension et/ou une sous-tension d’alimentation du ou des calculateurs (13, 14). L’état de sortie du superviseur d’alimentation (11, 12) correspondant au signal électrique déterminé appliqué en entrée est comparé au signal de sortie du ou des CAN (15 à 18) pour déterminer l’état de fonctionnement du superviseur d’alimentation, c’est-à-dire pour déterminer si le fonctionnement du superviseur d’alimentation est correct ou présente une anomalie. Figure pour l’abrégé : Figure 1The invention relates to a method and a device for controlling the power supply of computers (13, 14) of a vehicle. To this end, a determined electrical signal is applied to the input of one or more power supply supervisors (11, 12). The determined electrical signal is also applied to the input of one or more analog-to-digital converters, known as CAN (15 to 18). This determined electrical signal has specific characteristics making it possible to test whether the power supply supervisor (11, 12) correctly detects an overvoltage and / or an undervoltage in the supply to the computer (s) (13, 14). The output state of the power supply supervisor (11, 12) corresponding to the determined electrical signal applied to the input is compared to the output signal of the ADC (s) (15 to 18) to determine the operating state of the power supply supervisor , that is, to determine whether the operation of the power supply supervisor is correct or has an anomaly.
