Patent ID: 8839608

Claim:
A method of controlling an internal combustion engine including an exhaust line fitted with a particulate filter, comprising: acquiring a fill rate of the particulate filter; comparing, simultaneously, the fill rate with at least two determined thresholds; when the fill rate is less than the two determined thresholds, controlling the internal combustion engine at a first operating point such that a flow rate of particulates emitted from cylinders of the engine is not modified; when the fill rate is greater than the two determined thresholds, controlling the internal combustion engine at a second operating point such that the flow rate of particulates emitted from the cylinders of the engine is reduced; when the fill rate is between the two determined thresholds, determining an autonomy parameter and a probability parameter, the autonomy parameter being based on a calculated distance or duration available for regenerating the particulate filter with the fill rate between the two determined thresholds and the probability parameter being based on an estimated distance or duration needed to find running conditions suitable for regenerating the particulate filter; when the autonomy parameter is greater than the probability parameter, controlling the internal combustion engine at the first operating point; and when the autonomy parameter is less than the probability parameter, controlling the internal combustion engine at the second operating point.
