Abstract
(EN) An error determination device (40) for an exhaust gas purification device (7) having a filter device (72) and a pressure measurement device (73) comprises: a usability determination unit (44) that determines whether or not the pressure measurement device (73) can be used on the basis of the pressure and exhaust gas flowrate measured by the pressure measurement device (73); a frozen state determination unit (45) that determines whether or not the pressure measurement device (73) is frozen; and an error determination unit (46) that determines that there is an error for the pressure measurement device (73) when a determination has been made by the usability determination unit (44) that the pressure measurement device (73) is unable to be used and a determination has been made by the frozen state determination unit (45) that the pressure measurement device (73) is not frozen.
(FR) L'invention concerne un dispositif de détermination d'erreur (40) pour un dispositif de purification de gaz d'échappement (7) possédant un dispositif de filtre (72) et un dispositif de mesure de pression (73), comprenant : une unité de détermination d'utilité (44) qui détermine si le dispositif de mesure de pression (73) peut être ou non utilisé sur la base de la pression et du débit de gaz d'échappement mesurés par le dispositif de mesure de pression (73) ; une unité de détermination d'état gelé (45) qui détermine si le dispositif de mesure de pression (73) est ou non gelé ; et une unité de détermination d'erreur (46) qui détermine qu'il y a une erreur pour le dispositif de mesure de pression (73) lorsque l'unité de détermination d'utilité (44) a déterminé que le dispositif de mesure de pression (73) ne peut pas être utilisé et que l'unité de détermination d'état gelé (45) a déterminé que le dispositif de mesure de pression (73) n'est pas gelé.
