| 摘要 |
The invention relates to a system for estimating the mass of particles stored in a particle filter (2) mounted in the exhaust line (6) of an internal combustion engine (3) of a motor vehicle, including a means (7, 8, 15) for measuring a differential pressure across the terminals of the particle filter, a first estimation means (15) for estimating a differential particle flow across the terminals of the particle filter, a second estimation means (15) for estimating a differential pressure across the terminals of the particle filter, and a third estimation means (17) for estimating the mass of particles stored in the particle filter (2) according to the sum of the differential particle flow and a deviation calculated between the estimation and the measurement of the differential pressure. |
