Abstract

Procedimiento de mando de la depresión que reina en el colector de admisión de un motor de combustión interna (1) que propulsa un vehículo automóvil equipado con un dispositivo de frenado asistido por la citada depresión y mandado por pedal (15), pudiendo funcionar el motor (1) con mezcla aire/carburante pobre o con mezcla más rica, caracterizado porque, durante un funcionamiento con mezcla pobre: a) se detecta un accionamiento del pedal de freno (15) y se mide el tiempo que transcurre desde este accionamiento, y b) en cuanto se prolonga la duración del accionamiento más allá de un umbral (s1) predeterminado, se manda el paso al funcionamiento del motor (1) con mezcla más rica, para reforzar la citada depresión.
