Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the 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.

[0037] In the following description, a lot of specific details are set forth in order to fully understand the application, but the application can also be implemented in other ways different from those described here, and those skilled in the art can do without violating the connotation of the application. By analogy, the present application is therefore not limited by the specific embodiments disclosed below.

[0038] As mentioned in the background art section, at present, when a v...

Abstract

The embodiment of the present application discloses a vehicle control method. If the driving mode of the vehicle is regeneration mode, it is judged whether the temperature upstream of the DPF and the temperature upstream of the DOC of the vehicle meet the first preset condition. If the DPF If the difference between the upstream temperature and the target temperature upstream of the DPF is within a preset temperature range, and the temperature upstream of the DOC is greater than the temperature upstream of the DPF, then the spray of the preset rear spray element of the vehicle is reduced. oil quantity, to reduce fuel consumption, and increase the opening of the throttle valve of the vehicle to increase the intake air volume to reduce pumping loss, thereby reducing the fuel consumption and power loss of the vehicle using the vehicle control method .

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a vehicle control method. Background technique [0002] Driving regeneration is a kind of active regeneration of vehicles. Specifically, the temperature of the upstream of the DOC (that is, Diesel Oxidation Catalyst, oxidation catalytic converter) is increased by holding the throttle valve, and at the same time, the rear spray element 2 is turned on to make the vehicle spray The HC (that is, Hydrocarbon, hydrocarbon) is oxidized in DOC to release heat, and the temperature upstream of DPF (that is, Dieselparticulate filters, diesel particulate filter) is increased to accelerate the oxidation reaction rate of NOx and Soot (that is, soot), so that the DPF The adsorbed particles inside are removed. At present, the vehicles installed with DOC will have the problems of high fuel consumption and power loss during driving. Contents of the invention [0003] In order...
