Example 1

In accordance with an embodiment of the present invention, there is provided an embodiment of a method for controlling regeneration of a particulate trap, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than presented herein.

Fig. 1 is a flow chart of a control method for regeneration of a particle trap according to an embodiment of the present invention, as shown in fig. 1, the control method for regeneration of a particle trap comprises the following steps:

step S102, determining whether the regeneration interruption of the particle catcher is finished;

step S104, under the condition that the regeneration interruption of the particle trap is determined to be finished, acquiring the current carbon loading of the particle trap;

step S106, determining the corresponding carbon capacity grade based on the current carbon capacity;

it should be noted that the carbon loading level can be expanded according to the needs of the application scenario. In a specific implementation process, the carbon loading levels may be divided into different levels, for example, 3 levels, 4 levels, 5 levels, etc., according to the current carbon loading, and details thereof are not repeated herein.

And step S108, controlling the regeneration of the particle trap to be released according to the carbon loading level.

Through the steps, whether the regeneration interruption of the particle catcher is finished or not can be determined; under the condition that the regeneration interruption of the particle trap is determined to be finished, acquiring the current carbon loading of the particle trap; determining a corresponding carbon loading level based on the current carbon loading; the method controls the regeneration release mode of the particle trap according to the carbon loading level, and releases the regeneration of the particle trap through grading control according to the current carbon loading, so that the aim of preventing regeneration from frequently exiting and entering due to jumping of regeneration conditions is fulfilled, the technical effects of reducing the oil consumption of the whole vehicle and improving the fuel economy are achieved, and the technical problem of high oil consumption due to frequent entering of the regeneration process when the regeneration of the particle trap is interrupted is solved.

Optionally, determining the corresponding carbon load level based on the current carbon load comprises: acquiring a carbon loading threshold; and determining the carbon loading level corresponding to the current carbon loading according to the carbon loading threshold and the current carbon loading.

As an alternative embodiment, the carbon load threshold includes, but is not limited to, a first carbon load threshold, a second carbon load threshold, and a third carbon load threshold, wherein the first carbon load threshold > the second carbon load threshold > the third carbon load threshold. For example, when the current carbon loading is greater than the first carbon loading threshold, the carbon loading level corresponding to the current carbon loading is the first level; when the first carbon loading threshold value is larger than the current carbon loading value and the second carbon loading value is larger than the second carbon loading value, the carbon loading level corresponding to the current carbon loading value is the second level; when the second carbon loading capacity threshold value is larger than the current carbon loading capacity and larger than the third carbon loading capacity threshold value, the carbon loading capacity grade corresponding to the current carbon loading capacity is a third grade; when the third carbon loading threshold value is larger than the current carbon loading, the carbon loading level corresponding to the current carbon loading is a fourth level; in a specific implementation process, the carbon loading level corresponding to the current carbon loading can be flexibly divided according to the carbon loading threshold and the current carbon loading.

It should be noted that, when the current carbon loading is equal to the carbon loading threshold, the current carbon loading may be divided into the carbon loading levels related to the carbon loading threshold according to the needs of specific application scenarios.

Optionally, the carbon load threshold comprises a first carbon load threshold, and determining the corresponding carbon load level based on the current carbon load comprises: judging whether the current carbon loading is greater than a first carbon loading threshold value; determining that the carbon loading level corresponding to the current carbon loading is a first level under the condition that the current carbon loading is greater than a first carbon loading threshold, and controlling the regeneration of the particulate trap to be released according to the carbon loading level comprises the following steps: and controlling the particle catcher to be regenerated immediately under the condition that the regeneration of the particle catcher meets the regeneration general condition.

Because the carbon loading is difficult if too high regeneration temperature control, easily leads to whole car potential safety hazard, consequently needs the particulate matter in the timely processing DPF. In order to ensure the running safety of the whole vehicle, the particle trap is controlled to be immediately regenerated under the conditions that the carbon loading level corresponding to the current carbon loading is determined to be the first level and the regeneration of the particle trap meets the regeneration general condition.

Optionally, the carbon load threshold includes a first carbon load threshold and a second carbon load threshold, wherein the first carbon load threshold is greater than the second carbon load threshold, and determining the corresponding carbon load level based on the current carbon load includes: judging whether the current carbon loading is smaller than a first carbon loading threshold and larger than a second carbon loading threshold; determining that the carbon loading level corresponding to the current carbon loading is a second level when the current carbon loading is less than the first carbon loading threshold and greater than the second carbon loading threshold, wherein controlling the regeneration of the particulate trap to be released according to the carbon loading level comprises: in case the regeneration of the particle catcher meets the regeneration general condition, the particle catcher is controlled to be regenerated after a predetermined interval time is met.

It should be noted that, within the range of the first carbon loading threshold and the second carbon loading threshold, the sub-carbon loading thresholds may be further divided, for example, the first carbon loading threshold > the first sub-carbon loading threshold > the second carbon loading threshold. If the current carbon load is less than the first carbon load threshold and greater than the first sub-carbon load threshold, controlling the particulate trap to regenerate after a first predetermined interval time is met if regeneration of the particulate trap meets regeneration general conditions; if the current carbon load is less than the first sub-carbon load threshold and greater than the second carbon load threshold, controlling the particulate trap to regenerate after a second predetermined interval time is met if the particulate trap regeneration meets a regeneration general condition. Optionally, the first predetermined interval is less than the second predetermined interval.

By the method, the time interval for reentering regeneration can be set according to the current carbon loading capacity, and frequent exiting and entering of regeneration caused by jumping of regeneration conditions and increase of oil consumption are prevented.

Optionally, determining the corresponding carbon load level based on the current carbon load further comprises: judging whether the current carbon loading is smaller than a second carbon loading threshold value; determining that the carbon loading level corresponding to the current carbon loading is a third level under the condition that the current carbon loading is smaller than a second carbon loading threshold, and controlling the regeneration of the particulate trap to be released according to the carbon loading level comprises the following steps: and (4) resetting the particle catcher for regeneration.

When the current carbon load is less than the second carbon load threshold, the particulate trap regeneration may be reset because the current carbon load is relatively low, and when the current carbon load again reaches the regeneration threshold (except that the current carbon load is less than the second carbon load threshold), the regeneration may be triggered again. In this way, fuel waste caused by regeneration of the particulate trap when the current carbon loading is too small can be avoided.

An alternative embodiment of the invention is described below.

FIG. 2 is a block diagram of an overview of a particulate trap regeneration according to an alternative embodiment of the present invention, as shown in FIG. 2, wherein the particulate trap includes at least a fuel injector 21, an exhaust flow 22, an exhaust pipe 23, a DOC24, a DPF25, and a selective catalytic reduction 26. The regeneration request can be triggered after the carbon loading capacity in the DPF is accumulated to a certain value, the temperature of the DOC front section is increased to about 300 ℃ through technical means such as back injection, throttling valve, rail pressure reduction, advance angle adjustment and the like, so that the carbon hydrogen injected through the fuel nozzle can be combusted, then the carbon hydrogen is continuously injected to keep the temperature of the front end of the DPF at about 600 ℃, and the carbon loading capacity in the DPF is burnt.

The invention provides a scheme, when the regeneration interruption is finished, the regeneration is released according to the current carbon loading condition, and the over-high fuel consumption of the whole vehicle caused by frequent regeneration is avoided. When the interruption of DPF regeneration is judged to be finished, carrying out grading control according to the current carbon loading amount, and when the carbon loading amount exceeds a first-grade limit value, immediately releasing regeneration if the interruption is finished; if the carbon loading is between the first-level limit and the second-level limit, if the interruption is finished, the regeneration is released after a certain time T1; if the carbon loading is between the secondary limit and the tertiary limit, releasing regeneration at a certain time interval T2 if the interruption is finished, and if the carbon loading is lower than the tertiary limit, not releasing regeneration until the carbon loading reaches the regeneration limit again; a grading control scheme is adopted, and the fuel economy and the safety are considered; setting a time interval for re-entering regeneration according to the carbon loading; the method can prevent the regeneration from frequently exiting and entering due to the jump of the regeneration condition, so as to prevent the oil consumption from increasing; improves the fuel economy and has better market prospect.
