In vehicular field it is known that diesel engine in the combustion process of fuel/air mixture due to not exclusively firing
Burning will generate various types of particles, these particles include soot (carbon black) particle of such as tiny nanoparticle.From bavin
The soot of oil turbine and other particles have aggravated the Particulate Pollution in air, and to people's health nocuousness.Therefore, example
As since two thousand nine, particulate filter is widely installed in automobile, for filtering for example due to diesel fuel
Imperfect combustion generate hazardous particulate matter.The particulate filter can for example capture harmful charcoal of about 30%-95%
Cigarette, to improve urban air-quality and meet the laws and regulations requirement of such as EU 5 and the above standard.
As the emission regulation in global range is increasingly stringenter (such as release of EU 6C), many vehicular manufacturer are just
Considering for this particulate filter to be used for petrol engine, especially for the petrol engine using direct injection technology.
In addition, hazardous particulate matter will be gathered constantly on particulate filter with the lasting use of particulate filter.It is logical
Often, particulate filter is designed to need that it will be carried out in use for some time cleaning treatment (for example, in vehicle with certain
Load or speed traveling a period of time after, enough heats are generated, particulate filter is increased to sufficiently high temperature,
To burn the particle of accumulation；Or by pre-programmed engine is run under the mode that can be improved exhaust gas temperature),
So that particulate filter is restored to original working condition, and ensure the effective operation and service life of particulate filter.This
It is referred to as " filter regeneration " in this field.
If the regenerative process of particulate filter unsatisfactorily occurs during the normal use of vehicle, then can
Lead to the blocking of particulate filter.As a result, it is possible to create excessive back pressure, or even needs are eventually led to entire particle mistake
Filter is replaced.
For example, if vehicle usually exists regularly in high speed or high load downward driving sufficiently long time

Stroke or driving status by make its according to be conducive to particulate matter it is regenerated in a manner of carry out.In the case, for example, if very
The stroke of vehicle or driving status are unsuitable for the regeneration of particulate filter in long a period of time, then usually finally will be inevitable
The obstruction of ground generation particulate filter.
Especially, in the above prior art, generally can not provide or be readily available has with the regeneration event of particulate matter
The information of pass, therefore driver can not understand the regeneration event of particulate filter in real time.In the case, even if driver can
The alarm that warning light sending can be received before Severe blockage occurs in particulate filter may also can not make this appropriate
Reaction (or response), to also effectively can not prevent or avoid the generation of the blocking of particulate filter.

Specific embodiment
Below by way of exemplary embodiment the present invention is described in detail.It is noted that in the following description, in the application
The particulate filter mentioned is, for example, the diesel particulate filter used in the motor vehicles equipped with diesel engine, or
For the diesel particulate filter device used in the motor vehicles equipped with petrol engine.
Before the embodiment of the present invention is described, Typical particle mistake in the prior art is described with reference first to Fig. 1
The flow chart of filter regeneration process, in which it can be seen that soot load level in particulate filter gradually rise and it is related
The processes such as the sending of alarm signal.
As shown in Figure 1, in conventional particles filter regeneration in the prior art, with the fortune of vehicle motor
Row, such as the soot load in particulate filter is detected by charcoal smoke sensor.When soot load reaches " orange " water
When flat (rank), such as " orange " alarm can be issued and shown by the warning light in instrument board.
Then it, such as by temperature of the exhaust gas signals processor to the exhaust gas being discharged from the exhaust pipe of vehicle examines
It surveys, and verifies whether it meets required regeneration condition.If meeting regeneration condition, such as can be in the electronic control list of vehicle
The regeneration of particulate filter is automatically carried out under the control of first (ECU)；Otherwise it will continue to show " orange " alarm, and continue to test
Soot load and inspection regeneration condition are whether it is satisfied.
Then, if driving condition is constantly unfavorable for the generation of regenerative process and soot load continues to rise,
It is likely to be breached serious " red " level, it means that carrying out regeneration at this time is unsafe (such as Tai Re or temperature too high).
If soot load has reached serious " red " level, the person of being forbidden to use is used into regeneration strategy, and thus
Issue " red " alarm.Then, in the case where determining not up to safety margins, only allow vehicle dealer in strict control
Under the conditions of carry out forced regeneration process.
If above-mentioned grave warning by driver ignore and continue to test to soot load it is further up, need into one
Step judge soot load whether reach safety margins (that is, it is judged that soot load whether be too high and to can not to carry out it is safe again
It is raw).If soot load has reached safety margins, forbid all regenerative processes, only possible remedial measure is will be whole
A particulate filter is replaced (i.e., it is necessary to install new particulate filter), this will need to pay high cost.
Obviously, in the regenerative process of the above-mentioned prior art, driver can not comprehensively, in real time, accurately understand actual
Regeneration event, and positive or appropriate reaction can not be also made when the regeneration condition of particulate filter is not able to satisfy, thus
Ideal regeneration condition or regeneration effect cannot be obtained.
To overcome the defects of above-mentioned regenerative process in the prior art, according to an exemplary embodiment of the invention, propose
Particulate filter regeneration management system as shown in Figure 2 and particulate filter regeneration management method as shown in Figure 3.

In the use process of vehicle (such as automobile), as the engine of vehicle is activated, such as electronic control unit (ECU) will be requested
Soot load signal and the exhaust gas signals related to this from exhaust gas signals processor from soot load cell.It is logical
In normal situation, if soot load is sufficiently high and meets regeneration condition, electronic control unit will issue regeneration instructions to try
Figure starts regenerative process.However, if required regeneration condition cannot be satisfied forever and soot load continuous rise, most
Soot load is caused to meet or exceed predeterminated level at last.In the case, it will be necessary to issue initial warning letter to driver
Number, this is usually realized by the Amber Alert lamp on instrument board.
However, in particulate filter regeneration management method of the invention, main purpose is to enable driver
Sufficiently, the generation of regenerative process is understood in time, and is energetically got involved in the management of regenerative process, so that regenerative process energy
It reaches desirably or advantageous mode occurs, rather than the alarm signal that simply receiving may be ignored.
More specifically, it as shown in figure 3, in particulate filter regeneration management method of the invention, is run in engine
Period, such as loaded using the soot in soot load cell monitoring particulate filter.When confirmation soot load reaches pre-
After fixed horizontal, i.e. " orange " level, such as sentenced using the exhaust gas signals from the particulate filter that exhaust gas signals processor obtains
It is disconnected that regeneration condition (such as whether exhaust gas temperature reaches predeterminated level or sufficiently high) whether met.Meet regeneration condition in confirmation
In the case of, start the regenerative process of particulate filter, and export information related with regeneration event, example in real time on instrument board

Begin or carrying out, text message can show the prompt information for driver (for example, " if possible please with this
Mode continues to travel " etc. word contents), regeneration event item can show that regeneration is carrying out and its progress, thus driver
Such as it can be apprised of or prompt regeneration event.In other words, driver can obtain a variety of letters related with regeneration event
It ceases (such as text message, regeneration event item etc.), and can be guided or be encouraged with advantageous by these information or combinations thereof
Continue to drive vehicle in the mode of regenerative process.
