Embodiment Construction

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0057] The technical terms involved in this application are firstly introduced below.

[0058] Active regeneration refers to injecting fuel into the engine cylinder or injecting fuel into the exhaust pipe. The fuel burns in the diesel oxidation catalyst (DOC) to provide the high temperature required for active regeneration, so as to reduce DPF particles. Purpose. T...

Abstract

The invention discloses an active regeneration cooperative control method and system, a vehicle and a medium, and relates to the technical field of engines, the method is applied to the vehicle, and the vehicle comprises an electronic control unit (ECU) and a transmission control unit (TCU); the method comprises the steps that the ECU activates the active regeneration function of an engine; the active regeneration function comprises a driving active regeneration mode and a parking active regeneration mode; when the vehicle meets the neutral gear sliding condition, the TCU activates a neutral gear sliding function of a transmission so as to adjust the transmission to a neutral gear; the ECU switches the engine into the parking active regeneration mode, so that the rotating speed of the engine is increased, and active regeneration is carried out; and when the transmission exits the neutral gear sliding function, the ECU switches the engine into the driving active regeneration mode. According to the method, in the neutral gear sliding process, the engine is controlled to conduct active regeneration, the time proportion of active regeneration in the vehicle running process is increased, and fuel consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an active regeneration cooperative control method, system, vehicle and medium. Background technique [0002] Diesel engines are widely used in transportation, construction machinery and other fields due to their good economy, power, reliability and low CO and HC emissions. However, the particulate emission control of diesel engines has not been optimally controlled. At present, diesel vehicles are often equipped with a particle filter (Diesel Particulate Filter, DPF) to purify particulate pollutants in diesel engine exhaust. Since the particulate matter in the DPF device will cause the engine exhaust to be pressurized, which will affect the power and economy of the vehicle, it is necessary to regularly treat the particulate matter in the DPF. This process is called DPF active regeneration. [0003] At present, the common DPF active regeneration methods of the existing diesel eng...
