  • the present invention generally concerns diagnostics for an electric starter motor for a combustion engine.
  • the invention concerns in particular a system according to the preamble to claim 1 and a method according to the preamble to claim 1 1 .
  • the invention also concerns a computer program according to claim 21 and a computer-readable medium according to claim 22.
  • Document KR 100819334 describes a method in which the battery voltage to the starter motor and an rpm generated by the starter motor constitute the only input parameters for the diagnostics function .
  • the object of the present invention is consequently to provide a solution to the foregoing problem that enables automatic and efficient diagnostics of an electric starter motor, where neither the starter motor nor the machine in which it is included needs to be transported to a workshop.
  • this object is achieved by means of the system described above, wherein the system comprises a storage element configured so as to store a respective value for the status indicator in connection with a number of activations of the electric starter motor in a data series.

  • This system is advantageous because the error code need not be generated at a predetermined level for the status ind icator.
  • the system can instead react adaptively to any trend that indicates an unfavorable evolution in terms of the performance of the starter motor.
  • the alarm is appropriately generated if the starter motor is sufficiently worn that it will need to be replaced relatively soon , with the resu lt that it will be recommended that a visit to a workshop be scheduled in response to an alarm .
  • the processor is configured so as to analyze the data series by evaluating a rate at which the status indicator changes over time.

  • 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 .
  • the processor is configured so as to assign the status indicator a special value indicating that the function of the starter motor cannot be determined if the measured supply voltage is below a voltage threshold . If the supply voltage is too low, it is in fact impossible to draw any conclusions as to whether the fact that the combustion engine will not start is attributable to the starter motor being faulty, or whether the fault is attributable to something else, such as insufficient battery voltage.
  • the measuring elements are configured so as to measure the supply voltage and the rpm during a measurement interval, and the processor is configured so as to average the supply voltage and the rpm over the measurement interval.
  • the processor is also configured so as to determine the status indicator on the basis of an average value for the su pply voltage to the starter motor during the measurement interval and an average value for the rpm of the combustion engine during the measurement interval .

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).
