| 摘要 |
<p>The invention relates to a method for regulating the regeneration temperature of a particulate filter (14) for a vehicle engine, said engine including an exhaust line (10) comprising the following components disposed successively in the gas flow direction, namely: an oxidation catalyst (12) provided with a sensor that measures the temperature downstream of the catalyst (12) in the gas flow direction, and a particulate filter (14). The method comprises the following steps: acquiring information relating to the running profile of the vehicle; determining a target temperature (Ttarget) for the temperature downstream of the catalyst (12) as a function of the information acquired; regenerating the particulate filter (14); and, during the regeneration, adapting the target temperature (Ttarget) as a function of the changes in the temperature upstream of the particulate filter (14), which is estimated from the temperature measured by the sensor. Consequently, no temperature sensor is required upstream of the particulate filter.</p> |
