Abstract

Un motor (1) de combustión interna tiene un mecanismo (2) de relación de compresión variable que varía una relación de compresión mecánica y un mecanismo (7) de sincronización variable de válvulas que varía una sincronización de válvulas de una válvula (4) de admisión. Cuando hay una demanda para ejecutar el aprendizaje de la posición de referencia (etapa 21) para la calibración del sistema del mecanismo (7) de sincronización variable de válvulas, la ejecución del aprendizaje de la posición de referencia se permite bajo la condición de que la relación de compresión mecánica sea mayor que un valor VCRth de umbral (etapa 22). Cuando está presente alguna anomalía en el mecanismo (2) de relación de compresión variable, se prohíbe el aprendizaje de la posición de referencia del mecanismo (7) de sincronización variable de válvulas (etapas 23 y 25).
