Definitions

  • the invention relates to a method for correcting the position of the angle marks of an increment wheel of a speed and / or angle sensor of an internal combustion engine and a system therefor.
  • Incremental wheels are used to record the speed and angle, in particular crank angle and / or cam angle, of an internal combustion engine.
  • a 5 increment wheel has marks on its circumference, which are ideally attached with an equidistant angular distance.
  • the increment wheel is scanned by a sensor element.
  • a downstream edge evaluation detects the position of the marks from the sensor signal.
  • the actual crank angle is only inaccurately recorded by the marks of the increment wheel.
  • the tolerances of the increment wheel real, non-equidistant encoder wheel marks
  • sensor and flank evaluation falsify the angle recorded in this way.
  • non-equidistant angle marks can be recognized and then used to compensate for the angle errors. Since the models of the rotational irregularity of the motor are only partially accurate, the described separation of the signal components is only possible approximately. This leaves a residual error for the position of the angle marks. Furthermore, methods are known for using combustion chamber pressure sensors to record or control individual parameters of the combustion process in an internal combustion engine.
  • the object of the invention is to provide a method for correcting the position of the angle marks of an incremental wheel of a speed and / or angle of rotation sensor of an internal combustion engine and a system for this, which enables an adaptation of the signals of the incremental wheel in a simple yet very precise manner.
  • Figure 1 shows the cylinder pressure of various cylinders of an internal combustion engine, which over the

  • Angular distance ⁇ inkr ideally attached. (In the case of increment wheels with missing marks forming a reference gap, M corresponds to the number of complete marks).
  • a sensor element 2 scans the increment wheel.
  • the edge evaluation unit 3 detects the position of the marks from the sensor signal.
  • An increment counter 4 counts the number k of marks detected in the current segment. There are preferably 2M / Z stamps per segment.
  • the sensor wheel adaptation based on the cylinder pressure is preferably carried out in towing mode as soon as stable operating conditions are established for the specified speed.

  • the position of the angle marks can be adapted or corrected and the actual crank angle can be determined precisely. This enables more precise control of the internal combustion engine.

Abstract

La présente invention concerne un procédé pour corriger la position des marques angulaires d'une roue incrémentielle d'un capteur de vitesse de rotation et/ou d'angle de rotation d'un moteur à combustion interne, ainsi qu'un système associé. Les erreurs incrémentielles d'un système de mesure utilisé pour détecter une vitesse de rotation ou un angle d'onde sont déterminées, puis compensées à l'aide des informations du signal de pression de la chambre de combustion. La détermination précise de la position des marques angulaires de la roue incrémentielle et de la partie non équidistante des distances entre les marques angulaires permet de détecter de manière précise une vitesse de rotation et un angle d'onde.
