Detailed Description

In order to effectively control DPF regeneration time and improve the probability of DPF regeneration success, thereby reducing the risk of DPF overload, the embodiment of the application provides a DPF regeneration control method, a device, electronic equipment and a storage medium.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are for illustration and explanation only, and not for limitation of the present application, and embodiments of the present application and features of the embodiments may be combined with each other without conflict.

In order to facilitate understanding of the present application, the present application relates to the technical terms:

electronic control unit (Electronic Control Unit,) ECU: the ECU is also called an "engine electronic control unit", and is a controller that performs computation, processing, and judgment according to signals input from the sensors, and then outputs instructions to control the operation of the actuator.

Particulate matter trapping technology (Diesel Particulate Filter, DPF): the particulate matters in the exhaust gas of the engine are filtered and trapped through diffusion, deposition and impact mechanisms, and when the quantity of the trapped particulate matters reaches a certain degree, passive regeneration or active regeneration is required, so that the trapping capacity of the DPF on the particulate matters is recovered.

The exhaust particulate matter of an engine mainly comprises two components: unburned soot, ash, where particulate emissions are mostly composed of tiny particles of carbon and carbide.

The oxidation catalytic technology (Diesel Oxidation Catalysis, DOC) of particulate matter is to coat noble metal catalyst (such as Pt) on honeycomb ceramic carrier, and can be installed before DPF, so as to reduce the chemical reaction activation energy of HC, CO and SOF in the tail gas of engine, make these substances can be oxidized with oxygen in the tail gas at lower temperature and finally converted into CO ₂ And H ₂ O。

Active regeneration: by controlling air inlet and oil injection in an engine cylinder, the DOC is utilized to assist in improving the temperature in the particle catcher, so that carbon particles and oxygen are combusted and reacted, and the higher the temperature is, the faster the regeneration rate is.

Passive regeneration: the regeneration mode of low-temperature combustion reaction of carbon particles and nitrogen dioxide on the surface of the filter carrier is utilized without external intervention, and compared with active regeneration, the regeneration mode has the advantages that the temperature required by passive regeneration is lower, continuous regeneration of the DPF can be realized, but the regeneration efficiency is low.

It should be noted that the description of "first", "second", etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of technical features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present application.

Along with the lengthening of the working time, more and more particles are accumulated on the DPF, so that the filtering effect of the DPF is influenced, the exhaust back pressure is increased, the ventilation and combustion of an engine are influenced, the power output of the engine is reduced, the oil consumption is increased, and the performance of the engine is reduced.

Currently, active regeneration in DPF regeneration is generally performed periodically, and active regeneration refers to raising the temperature in the DPF by using external energy to burn particulate matters. Specifically, when the differential pressure sensor detects that the back pressure of the front and the rear of the DPF is too large, the accumulated carbon quantity carried by the DPF is considered to be reached, and at the moment, the temperature in the DPF is increased by external energy, such as diesel oil injection and combustion before the DOC, so that the temperature in the DPF reaches a certain temperature, and deposited particulate matters are oxidized and combusted to achieve the aim of regeneration. The DPF temperature is raised to a prescribed temperature, typically 550 ℃ or higher, and the trapped particulates therein are burned to restore the trapping ability of the DPF. However, the operation condition of the engine of some special-purpose vehicles for hybrid power is poor, and the exhaust temperature cannot reach the required temperature, so that the DPF in the aftertreatment system is often subjected to incomplete regeneration in an active regeneration mode, and the carbon load can be judged inaccurately due to multiple incomplete regenerations, so that particulate matters are accumulated, and the risk of DPF overload is caused.

In view of this, the inventors have found that, when the engine drives the generator to generate electricity, the engine load increases, and the aftertreatment temperature increases during this process, which is advantageous for DPF regeneration. Accordingly, the DPF regeneration control method provided by the embodiment of the present application may include: and the ECU acquires the carbon load in the DPF, and when the carbon load is determined to be larger than a first carbon load threshold, judges whether the driving state is in a driving power generation state, wherein the driving power generation state characterizes an engine to drive a generator to charge a battery, and controls the DPF to enter a regeneration mode after the driving state is determined to be in the driving power generation state.

Like this, when the carbon loading in the DPF satisfies first carbon loading threshold value, utilize the generator to charge the mode that increases engine load for engine oil injection volume increases, and then leads to DPF inside temperature to rise in the aftertreatment, has improved the probability that DPF regeneration was successful, thereby has reduced DPF overload risk.

In order to facilitate understanding of the specific implementation of the DPF regeneration control method according to the embodiment of the present application, the following description will be given with reference to the accompanying drawings.

Fig. 1 is a flowchart of a DPF regeneration control method according to an embodiment of the present application, which is applied to an ECU, and includes the following steps.

Step 101: the carbon loading within the particulate trap DPF is obtained.

In specific implementation, the carbon loading in the DPF may be obtained by means of an exhaust back pressure method, a travel time method, a soot emission method, a model calculation method, a differential pressure-based carbon loading estimation method, and the like, which may not be specifically limited in the embodiment of the present application.

Step 102: and when the carbon loading is determined to be larger than the first carbon loading threshold, judging whether the driving state is in a driving power generation state, wherein the driving power generation state represents that the engine drives the generator to charge the battery.

In practice, the carbon loading in the DPF is continuously accumulated, and when the carbon loading is accumulated to a certain value, the DPF needs to be cleaned, for example, the DPF is cleaned once every time the carbon loading is accumulated to 3.5g, that is, the regeneration process is performed, so the first carbon loading threshold can be set to 3.5g, that is, the preset carbon loading when triggering the regeneration of the DPF can also be set to be lower than 3.5g, which can be specifically set by a technician.

In particular, vehicle driving power generation is typically triggered by the vehicle controller (Hybrid Control Unit, HCU) determining that a preset driving power generation condition is met, for example, when the battery power of the vehicle is lower than a preset power threshold, for example, 30%, when driving power generation is triggered, the engine drives the generator to charge the battery, and because the generator generates power, the engine load is increased, and when the HCU determines that a preset vehicle exiting power generation condition is met, the vehicle exiting power generation state is controlled.

Wherein the preset exiting driving power generation condition includes, but is not limited to, part or all of the following conditions:

the battery charge reaches a full threshold, such as 80% of the charge;

the charging time length reaches a preset time length threshold value;

receiving a power generation instruction for stopping driving;

the vehicle is turned off and the engine stops running.

Step 103: and after the running state is determined to be in the running power generation state, controlling the DPF to enter a regeneration mode.

When the DPF is in the regeneration mode, the DPF is controlled to enter the regeneration mode, so that the DPF can be better regenerated, and the probability of success of regeneration is increased.

In practical applications, a certain regeneration time is usually required during DPF regeneration, so in order to better help DPF regeneration, the probability of success of DPF regeneration is increased, and in fact, the probability of success of DPF regeneration can be further increased by controlling the DPF regeneration timing in the following manner.

Fig. 2 is a flowchart of another DPF regeneration control method according to an embodiment of the present application, which is applied to an ECU, and includes the following steps.

In step 201, a carbon loading within a particulate matter trap DPF is obtained and it is determined that the carbon loading is greater than a first carbon loading threshold.

Step 202, judging whether the driving state is in a driving power generation state, wherein the driving power generation state represents that an engine drives a generator to charge a battery, if so, entering step 203, and if not, entering step 205.

Step 203, determining whether the remaining duration of the running power generation is greater than a preset regeneration duration, wherein the remaining duration of the running power generation is a charging duration from the current battery power to the first battery power, the preset regeneration duration is a duration from the start of regeneration to the end of regeneration of the DPF, if yes, entering step 204, and if no, entering step 205.

In specific implementation, the remaining duration of the driving power generation is actually estimated charging duration from the current battery power to the first battery power, and the first battery power may be preset power for indicating the end of the driving power generation, for example, 100% or 80%, and may be specifically modified as required.

For example, taking the first battery power as 80% as an example, a preset number of driving power generation time periods from 30% to 80% of the battery power are obtained in advance to obtain an average value of the driving power generation time periods, and then when the driving power generation remaining time periods are judged, the driving power generation remaining time periods from the current battery power to the first battery power can be determined according to the average value of the current battery power and the driving power generation time periods.

Assume that the driving power generation time periods when the battery is charged from 30% to 80% are respectively time period a:50 minutes, time period b:48 minutes, and time period c:52 minutes, the average value of the obtained driving power generation duration is 50 minutes, if the carbon load is greater than the first carbon load threshold and the driving state is in the driving power generation state, and the current battery power is 50 minutes, the driving power generation time from 50% to 80% can be estimated to be 30 minutes according to the average value of the driving power generation duration of 50 minutes, namely the driving power generation remaining duration is 30 minutes, a timer can also be set, when the driving power generation is determined, the driving power generation duration is started by using the timer, when the carbon load is greater than the first carbon load threshold and the driving state is in the driving power generation state, the difference value between the timing result and the average value of the driving power generation duration of 50 minutes is determined to be the driving power generation remaining duration, or when the driving power generation is determined to be started, the average value of the driving power generation duration of 50 minutes is taken as the starting value of the timer, then the countdown is started, when the carbon load is greater than the first carbon load and the driving power generation state is not in the driving power generation state, the timing result is determined to be the driving power generation remaining duration, and the driving power generation remaining duration can be determined in other ways.

The DPF preset regeneration duration is an estimated duration from the regeneration start to the regeneration end, wherein the regeneration start refers to reaching the DPF regeneration timing, the regeneration start is the regeneration start, the regeneration end refers to reaching the DPF exit timing, the regeneration end is the regeneration end, and the DPF exit status can be obtained specifically through multiple tests, for example, under different working conditions, the duration from the regeneration start to the regeneration end of multiple times is counted, and then the average value or the maximum value of the multiple regeneration durations is determined as the preset regeneration duration.

Step 204, control DPF enters a regeneration mode.

When the running power generation remaining time is longer than the preset regeneration time, the DPF is controlled to enter a regeneration mode, so that the DPF can be further ensured to be completely regenerated, and the probability of success of DPF regeneration is improved.

In step 205, control does not enter the regeneration mode for the DPF.

Since the DPF regeneration requires a certain time to be complete, in order to better ensure the regeneration time of the DPF, the embodiment of the present application may further perform the action of step 202 after determining that the current battery level satisfies the regeneration condition.

In specific implementation, before judging whether the driving state is in the driving power generation state, the current battery power is lower than the second battery power, wherein the charging time period from the second battery power to the first battery power is lower than the preset regeneration time period.

Assuming that the preset regeneration period is 20 minutes, the first battery power is 100%, and 20 minutes are required on average from 80% to 100%, then the second battery power may be set to 80%, because when the carbon load satisfies the first carbon load threshold, if the current battery power is already 80%, on one hand, the current battery power may be in a running power generation state, but the running power generation remaining period at this time is likely not to satisfy the preset regeneration period, even if the control is in the regeneration mode, the regeneration is not guaranteed to be complete, on the other hand, the current battery power reaches 80%, meaning that the battery power is sufficient, and may not be in the running power generation state, so, in order to ensure the regeneration to be complete, the current battery power is not controlled to enter the regeneration mode at this time, and the control is performed to enter the regeneration mode according to whether the running power generation state is in the running power generation state after the battery power consumption.

Therefore, the DPF regeneration time length can be primarily screened, the flexibility and convenience of the scheme are improved, and the effectiveness of judging the running power generation state is ensured.

In a specific implementation, after determining that the carbon loading is greater than the first carbon loading threshold, it may also be determined whether the carbon loading is greater than a second carbon loading threshold, where the second carbon loading threshold is determined according to a lower limit of the carbon loading overload interval, and when determining that the carbon loading is greater than the second carbon loading threshold and the DPF does not enter the regeneration mode, the DPF is controlled to enter the regeneration mode.

For example, the first carbon loading threshold is set to 3.5g, and when the carbon loading in the DPF reaches 7g, the carbon loading overload interval lower limit may be determined to be 7g, then the second carbon loading threshold may be set to be lower than 7g according to the carbon loading overload interval lower limit, or may be set to be 7g, or may be set by a technician, for example, the second carbon loading threshold is set to be 5g, so that when the carbon loading is greater than the second carbon loading threshold, the DPF regeneration is started immediately without judging other conditions such as driving state, and DPF overload may be further prevented.

Thus, when the DPF carbon loading is greater than the second carbon loading threshold, if the DPF does not enter the regeneration mode at this time, the DPF can be immediately controlled to enter the regeneration mode to protect the DPF from overload.

In specific implementation, after the DPF is controlled to enter the regeneration mode, when it is determined that the carbon load reaches the exit regeneration threshold, the DPF may be controlled to exit the regeneration mode, for example, the exit regeneration threshold is set to 0.5g.

Thus, by setting the exit regeneration threshold, DPF cycle regeneration can be avoided, and DPF burn-out can be prevented.

Based on the same technical concept, the embodiment of the application also provides a DPF regeneration control device, and the principle of solving the problem of the DPF regeneration control device is similar to that of the DPF regeneration control method, so that the implementation of the DPF regeneration control device can be referred to the implementation of the DPF regeneration control method, and the repetition is omitted.
