Abstract

La présente invention a pour objet un procédé (200) d’analyse d’une température d’un élément d’un véhicule automobile, dans lequel le procédé (200) comprend au moins une première étape (201) de mesure d’une première information de température (T) de l’élément à un premier instant (X1), puis une deuxième étape (202) de mesure d’une deuxième information de température (T’) de l’élément à un deuxième instant (X2), puis une troisième étape (203) qui consiste à calculer une différence (D) entre la première information de température (T) et la deuxième information de température (T’), puis une quatrième étape (204) qui consiste à déterminer une borne inférieure (Tmin) et une borne supérieure (Tmax) d’un intervalle (I) de température, puis une cinquième étape (205) de vérification si la différence (D) entre la première information de température (T) et la deuxième information de température (T’) est comprise dans l’intervalle (I) de température, puis une sixième étape (206) qui consiste à incrémenter un nombre d’erreurs (N) en un nombre incrémenté (N+1), si la différence (D) est comprise dans l’intervalle (I) de température, puis une septième étape (207) qui consiste à comparer le nombre incrémenté (N+1) à un nombre seuil (N’), puis une huitième étape (208) qui consiste à transmettre une alerte (Y), si le nombre incrémenté (N+1) est supérieur ou égal à un nombre seuil (N’) d’erreurs, puis la première étape (201) si le nombre incrémenté (N+1) est inférieur au nombre seuil (N’) après un premier laps de temps (L1) ou bien si la différence (D) n’est pas comprise dans l’intervalle (I) de température, après un deuxième laps de temps (L2). Figure 4The present invention relates to a method (200) for analyzing a temperature of an element of a motor vehicle, in which the method (200) comprises at least a first step (201) of measuring a first temperature information (T) of the element at a first time (X1), then a second step (202) of measuring a second temperature information (T ') of the element at a second time (X2), then a third step (203) which consists in calculating a difference (D) between the first temperature information (T) and the second temperature information (T '), then a fourth step (204) which consists in determining a lower limit (Tmin) and an upper bound (Tmax) of a temperature interval (I), then a fifth step (205) of checking whether the difference (D) between the first temperature information (T) and the second temperature information (T ') is included in the temperature interval (I), then a sixth step (206) which consists in inc rement a number of errors (N) into an incremented number (N + 1), if the difference (D) is within the temperature interval (I), then a seventh step (207) which consists in comparing the number incremented (N + 1) to a threshold number (N '), then an eighth step (208) which consists in transmitting an alert (Y), if the incremented number (N + 1) is greater than or equal to a threshold number ( N ') of errors, then the first step (201) if the incremented number (N + 1) is less than the threshold number (N') after a first lapse of time (L1) or if the difference (D) n 'is not included in the temperature interval (I), after a second period of time (L2).
