Abstract

The embodiment of the invention discloses a GPF regeneration control method and device for an automobile and a computer storage medium, and belongs to the technical field of vehicle engineering. The method comprises the steps that: in the running process of an engine of the automobile, when a GPF of the automobile meets a regeneration control condition, operation information of the automobile is obtained; according to the operation information, whether the GPF meets an electric heating regeneration condition or not is determined; and when the GPF meets the electric heating regeneration condition, a heating circuit in the GPF is controlled to electrically heat the GPF, so as to achieve the regeneration of the GPF. According to the GPF regeneration control method and device disclosed by the embodiment of the invention, when the GPF meets the regeneration control condition and the electric heating regeneration condition in sequence, the GPF is electrically heated through the GPF heating circuit so as to achieve the regeneration of the GPF, so that the regeneration of the GPF is achieved without controlling the ignition angle, the regeneration control efficiency is improved, and the dynamic economy and the user viscosity are improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicle engineering, and in particular, to a regeneration control method, device and computer storage medium for a GPF (Gasoline Particulate Filter, particulate matter trap) of an automobile. Background technique [0002] With the development of society, automobiles have gradually become an essential means of transportation for people to travel, and with the increase in the number of automobiles, the pollution of automobile exhaust emissions to the environment is becoming more and more serious. Exhaust emissions comply with national laws and regulations, and GPF can be added to the gasoline engine emission treatment system of automobiles, and particulate matter emissions can be reduced through this GPF. When a car equipped with GPF runs for a certain period of time, a certain amount of carbon load will accumulate in the GPF. When the carbon load accumulates to a certain level, ...
