Problems solved by technology

[0003] However, in the actual running process, the vehicle does not always run in a normal state, for example, when the intake system of the vehicle engine fails, the carbon particles accumulated on the DPF will grow exponentially due to insufficient combustion , if the system still controls the time of the next regeneration of the DFP with the model under normal working conditions, the DPF regeneration of the vehicle will be seriously inconsistent with the actual demand

Embodiment Construction

[0022] It should be understood that the drawings are only used to illustrate the present application.

[0023] Please refer to figure 1 As shown, it is a flow chart of the control method of the DPF regeneration time of the diesel engine vehicle of the present invention. A diesel engine vehicle has a control system that controls the operation of the vehicle, exhaust gas treatment, communication and other matters through the signal acquisition of sensors and actuators arranged on the vehicle, including pressure sensors, temperature sensors, etc., which can be an integrated whole. The control system can also be composed of multiple subsystems. In step S01, the control system is activated, and then, in step S02, the control system detects whether there is an error reported due to a failure of the vehicle air system. Errors caused by air system failures in the present invention include errors received by the vehicle control system from sensors or actuators caused by blockage or l...

Abstract

The invention provides a method for controlling the regeneration time of a DPF (diesel particulate filter) of a diesel engine vehicle, which comprises the following steps of: using a first mode when a report error caused by air supply is not received, and determining the regeneration time of the DPF of the vehicle according to three factors of mileage, fuel consumption and engine running time in the first mode; and a second mode in which the DPF regeneration time is determined using a shorter method than in the first mode until the next DPF regeneration time is used when a report error due to the air supply is received. By means of the mode, the problem that when an air system reports errors, the regeneration time of the DPF is difficult to control accurately can be solved.

Description

technical field [0001] The present application relates to the field of a diesel engine exhaust gas processor, and in particular, to a method for controlling the regeneration time of a DPF of a diesel engine vehicle, a program product, and a method for regenerating the DPF. Background technique [0002] An exhaust gas processor of a diesel engine includes a Diesel Oxygen Catalyst (DOC) and a Diesel Particle Filter (DPF) for removing carbon particles. When the carbon particles on the DPF accumulate to a set predetermined value, the regeneration of the DPF needs to be started. When setting the interval from the last regeneration to the next regeneration, various methods can be used, and multiple parameters need to be considered, for example, the mileage, fuel consumption, engine running time, etc. need to be considered at least. In the case of considering the above-mentioned factors, the conditions for starting the DPF next time under normal driving conditions are calibrated. ...
