Carbon quantity regeneration monitoring method, device and equipment and storage medium

Abstract

The invention belongs to the technical field of automobiles, and discloses a carbon regeneration monitoring method, device and equipment and a storage medium. The method comprises the steps that when a vehicle is in the regeneration process, the current carbon amount, the oxygen flow of an inlet of a particulate filter, the temperature of the particulate filter and the regeneration time are obtained in real time; querying a first preset table according to the current carbon amount, and determining a regeneration rate corresponding to the current carbon amount; querying a second preset table according to the oxygen flow rate at the inlet of the particulate filter and the temperature of the particulate filter to obtain a regeneration combustion rate coefficient corresponding to the oxygen flow rate at the inlet of the particulate filter and the temperature of the particulate filter; and determining the corresponding carbon regeneration amount according to the regeneration rate, the regeneration combustion rate coefficient and the regeneration time. By means of the mode, the regeneration process of the particulate filter is monitored, the influence of the current carbon amount of the particulate filter, the oxygen flow of an inlet of the particulate filter and the temperature of the particulate filter on the combustion rate is considered, and the monitoring precision of the carbon regeneration process is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, and in particular, to a method, device, equipment and storage medium for monitoring carbon content regeneration. Background technique [0002] The regeneration safety of GPF (particulate filter) is one of the most important links in the stable operation of the engine aftertreatment system, which is mainly affected by factors such as regeneration temperature control, carbon load during regeneration, and regeneration conditions. In order to ensure the normal operation of the vehicle system, it is necessary to monitor the regeneration process of the GPF. At present, after the GPF is regenerated, the residual carbon content is calibrated again through the differential pressure model, and the regeneration process cannot be monitored. [0003] The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is ...
