The invention discloses a DPF regeneration control method and device, a storage medium and computer equipment. The method comprises the steps: obtaining pressure difference before and after a first DPF collected at the first moment and the pressure difference before and after a second DPF collected at the second moment, wherein the second moment is later than the first moment; determining pressuredifference increasing rate between the first moment and the second moment according to the pressure difference before and after the first DPF and the pressure difference before and after the second DPF; and when the pressure difference increasing rate is larger than preset increasing rate, determining DPF carbon load according to a preset carbon load determination model, and performing DPF regeneration according to the determined DPF carbon load. According to the technical means for judging whether the DPF needs to be regenerated or not through the DPF carbon load determined by the preset carbon load determination model, the technical problem of shortening the service life of the DPF caused by excessive DPF regeneration in the prior art is solved, and the technical effect of prolonging the service life of the DPF is achieved.
Description
technical field [0001] The invention relates to the field of vehicle exhaust control, in particular to a DPF regeneration control method, device, storage medium and computer equipment. Background technique [0002] On June 22, 2018, my country issued the national standard (standard number GB17691-2018) of "Heavy-duty Diesel Vehicle Pollutant Emission Limits and Measurement Methods (China Phase VI)". The national standard will come into effect on July 1, 2019. my country's pollutant emission requirements for various vehicles, including heavy-duty diesel vehicles, are getting higher and higher, which is conducive to the continuous optimization of my country's natural environment. [0003] In the prior art, vehicle exhaust gas is often purified by a particulate filter (DPF, Diesel Particulate Filter). DPF can capture particulate matter in the exhaust gas, such as carbon particles, so as to achieve exhaust gas purification. As time goes by, the DPF captures more and more part...
