Taking the temperature into account in this way is advantageous, as environmental changes (such as those depending on seasonal variations and/or geographical cond itions) can be weighed in in the diagnostic method in a natural and adequate manner.
  • the viscosity of the oil in the combustion engine in fact varies considerably with the temperature, which is in turn reflected in the measured rpm .
  • said object is achieved by means of the method described above, wherein a respective value for the status indicator in connection with a number of activations of the electric starter motor is stored in a storage element in the form of a data series.
  • the data series is analyzed and , on the basis of said analysis, a determination is made as to whether or not the function of the electric starter motor is acceptable. An error code is generated if the function is not determined to be acceptable.

  • the rpm RPM of the combustion engine 120 will be discussed throughout in the description that follows. Because the starter motor 1 10 and the combustion engine 120 are coupled together (for example via a so-called Bendix clutch), there is naturally a correlation between the rpm of the combustion engine 120 and the rpm of the starter motor 1 10, with the resu lt that a measured rpm for the starter motor 1 10 can be utilized just as well as the proposed rpm RPM of the combustion engine 120.
  • the temperature measuring element is configured so as to measure at least one temperature related to the machine in which the starter motor 1 10 is included .
  • Said at least one temperature can , for example, pertain to an ambient temperature, an oil temperature in the eng ine, a cooling fluid temperature, an engine block temperature, a starter motor temperature and/or a battery temperature.

This also makes it possible for the decision regarding the generation of any error code E to be made based on adequate grounds, with the result that the reliability of the error code E is relatively high .
  • the processor 160 can consequently be configured so as to take into account at least one parameter that describes the conditions under which the status indicator S was generated . If the status indicator S is determined to have been generated under a first type of cond itions, then the processor 1 60 is further configured so as to guide the storage of the status ind icator to a first data series in the storage element 1 70. If the status indicator S is instead determined to have been generated under a second type of conditions, then the processor 160 is configured so as to guide the storage of the status indicator S to a second data series in the storage element 1 70, and so on . The processor 160 then analyzes each data series individually and determines, on the basis thereof, whether the function of the electric motor 1 10 is acceptable. The processor 160 generates an error code E in the event that the function is not determined to be acceptable.
  • the system also comprises elements for processing the error code E in their turn.

  • Figure 2a shows a first graph of an example of how the status indicator S can change over time, wherein the horizontal axis represents a number n of activations of the starter motor 1 10 and the vertical axis represents the values for the status indicator S in a data series M .

  • the horizontal axis thus represents not only a sequence, but rather reflects a common chronolog ical distance between the values in the data series M .
  • the activations of the electric starter motor 1 10 that are contained in the data series M are consecutive, i.e. there are no gaps in the data series M , and the values therein are processed in the order in which they were stored .

  • the slope of the graph R t0 : ti between a measurement instance t 0 and a measurement instance t respectively corresponding to the activations n+1 is relatively steep, while the slope of the graph R n : n + i between n and n + 1 is relatively flat.

Abstract

L'invention concerne un démarreur électrique (110) agencé de manière à démarrer un moteur à combustion (120). Le fonctionnement du démarreur (110) est soumis au diagnostic au moyen d'éléments de mesure (130, 140) qui mesurent une tension d'alimentation (U) au niveau du démarreur et un nombre de tours par minute (RPM) du moteur à combustion. En fonction des paramètres mesurés (U, RPM), un processeur (160) détermine un indicateur de statut (S) qui fournit une mesure de la qualité pour la performance du démarreur (110). Un élément de stockage (170) stocke une valeur respective pour l'indicateur de statut (S) se rapportant à un nombre d'activations du démarreur électrique (110) dans une série de données (M). Le processeur (160) analyse la série de données (M) et détermine, en fonction de celle-ci, si le fonctionnement du démarreur électrique (11) est acceptable et, s'il est déterminé que le fonctionnement n'est pas acceptable, il génère un code d'erreur (E).
