Dpf regeneration trigger control method, terminal device, and storage medium

Abstract

The present application relates to a kind of DPF regeneration trigger control method, terminal equipment and storage medium, the method includes: setting forced trigger pressure difference value and initial trigger pressure difference value, wherein initial trigger pressure difference value is less than forced trigger pressure difference value;In the process of vehicle driving, the pressure difference value of DPF is collected in real time, and the following judgment and control are carried out: when the pressure difference value is greater than forced trigger pressure difference value, control vehicle forced start DPF regeneration;Otherwise, when the pressure difference value is greater than initial trigger pressure difference value, judge whether engine exhaust temperature reaches natural DPF regeneration requirement temperature, if so, trigger natural DPF regeneration;Otherwise, according to the situation of road slope in front, the probability of starting DPF regeneration in the predicted distance in front of the current position of vehicle is predicted, if the probability is greater than probability threshold, then do not start;Otherwise, control vehicle forced start DPF regeneration.The flexible trigger area set by the present application has a certain tolerance space, which can reduce the fuel consumption of diesel engine and improve economy.
