ECU50 implements following regeneration actions: so that the temperature of GPF29B is increased to defined lower limit again using the heat of exhaust gas More than raw temperature, the particulate matter for trapping GPF burns.
Here, in order to regenerate GPF29B needing that GPF29B is enable to be warming up to the regenerated temperature of GPF29B.If in order to make GPF29B heating and retarded spark timing significantly, it is likely that increase the noise of engine 20 and vibration and make fuel efficiency It can decline.
It is therefore preferable that ignition timing will not be enable to postpone and can obtain significantly the engine of the regenerated temperature of GPF29B It exports operate engine 20.In addition, engine output when GPF29B regenerates is got over for the raising etc. of fuel efficiency It is small better.
For this purpose, in the present embodiment, as shown in figure 4, regeneration treatment mapping is previously stored in ECU50, at the regeneration Manage the correlation of the engine output and GPF temperature of mapping definition engine 20.
In Fig. 4, ceiling temperature line L (height) and lower limit temperature line L (low), upper limit temperature are set in regeneration treatment mapping Degree line L (height) is linked to be by the maximum temperature for corresponding to the GPF29B of engine output, and lower limit temperature line L (low) is by corresponding to It is linked to be in the minimum temperature of the GPF29B of engine output.

In the mapping of Fig. 4, in by ceiling temperature line L (height) and lower limit temperature line L (low) area encompassed, include Can be increased to GPF temperature without retarded spark timing etc. can regenerated lower limit temperature (hereinafter also referred to lower limit regenerative temperature Degree) more than region (continuous reproducible region A).
In addition, existing can be with point in by ceiling temperature line L (height) and lower limit temperature line L (low) area encompassed Delay of fiery timing etc. is the region (conditional continuous reproducible region B) that GPF temperature is increased to energy regeneration temperature by condition.
In conditional continuous reproducible region B, the range of engine output is set to include lower limit regenerative temperature.? This, " continuous " of continuous reproducible region A and conditional continuous reproducible region B refer to GPF29B not less than lower limit regenerative temperature And it being capable of continuity ground constant regeneration.
ECU50 makes GPF40 start regenerated regulation regeneration beginning condition establishment, and engine 20 can be in regeneration treatment In the region between ceiling temperature line L (height) and lower limit temperature line L (low) in mapping, engine output range quilt It is set as making engine 20 can in conditional when including that the conditional continuous reproducible region B of lower limit regenerative temperature is operated Among the B of cyclic regeneration region, GPF29B temperature is that the region B1 of lower limit regenerative temperature or more is operated.
In addition, among conditional continuous reproducible region B, the temperature of GPF29B be lower limit regenerative temperature region below B2 is that the PM in GPF29B can not be made to burn, can not implement the region of regeneration actions.
In addition, being located at starting for lower limit regenerative temperature and the intersection point C of lower limit temperature line L (low) in regeneration treatment mapping Machine output is set to upper limit engine output P (height), and it is conditional continuous reproducible region which, which exports P (height), The upper limit value of engine output in B.
In addition, being located at starting for lower limit regenerative temperature and the intersection point D of ceiling temperature line L (height) in regeneration treatment mapping Machine output is set to the initial value of limit engine output P (low), and it is that conditional can be continuous which, which exports P (low), The lower limit value of engine output in regeneration zone B.
It is that limit engine exports P (low) or more simultaneously that ECU50, which requests output in the driver that driver requests to vehicle 10, And exported in P (height) situation below for upper limit engine, operate engine 20 with upper limit engine output P (height), And make ISG40 to request the poor corresponding power generation torque of output to be sent out with upper limit engine output P (height) and driver Electricity, with from ISG40 with the torque that generates electricity generated electricity brought by, the charged state of battery 70 is to the upper limit of regulation range of management It is worth side to increase, limit engine output P (low) is corrected from initial value to increased direction.
In addition, in the present embodiment, in the case where charged state is not up to the lower limit value of range of management, ECU50 makes to send out Motivation 20 is operated with upper limit engine output P (height), and charged state is lower, and limit engine is more exported P (low) from first Initial value is corrected to reduced direction.
In addition, in the present embodiment, ISG40, which has, assigns complementary driving force to engine 20 using the electric power of battery 70 (auxiliary) function, ECU50 the charged state of battery 70 be more than range of management upper limit value in the case where, make engine 20 with Limit engine output P (low) is operated.
In addition, in the present embodiment, ECU50 is the case where driver requests output to be greater than upper limit engine output P (height) Under, make engine 20 request output to operate with driver, requests output to be less than upper limit engine output P (height) in driver In the case where, forbid the Regeneration control of GPF29B.
Referring to Fig. 2 and flow chart shown in Fig. 3, illustrate by the ECU50 progress of vehicle 10 formed as described above One example of the regeneration actions of GPF29B.
In Fig. 2, ECU50 judges whether GPF regeneration mark establishes (step S1) repeatedly.Here, GPF regeneration mark is for example It is established in the case where the PM accumulating amount being estimated as in GPF29B is regulation accumulating amount or more.ECU50 is pushed away by defined method Determine PM accumulating amount.
In the case that GPF regeneration mark is established in step sl, ECU50 is determining and updates conditional continuous reproducible area Domain (step S2).Here, ECU50 corrects limit engine output P (low), correction according to the SOC of battery 70, catalyst temperature The peak width in conditional continuous reproducible region.
Here, the upper limit value of peak width is the upper limit value (output of upper limit engine) of engine output, peak width Lower limit value is the lower limit value (limit engine output) of engine output.In step S2, the band of ECU50 referring to Figure 5 Condition continuous reproducible peak width determines mapping to be corrected.
In Fig. 5, conditional continuous reproducible peak width determine mapping be define battery 70 SOC and conditional can The mapping of the relationship of the width of cyclic regeneration region B.The lower limit value of the range of management of the mapping is for example set as 30%, upper limit value Such as it is set as 70%.
In the mapping, the width of conditional continuous reproducible region B is maximum when SOC is in range of management.In addition, The width of becoming larger or becoming smaller with SOC, conditional continuous reproducible region B becomes smaller.In the present embodiment, the SOC of battery 70 More it is greater than the upper limit value of range of management, then ECU50 is more by upper limit engine output P (height) from initial value to the direction school to become smaller Just, so that the width of conditional continuous reproducible region B be made to become smaller.And on the other hand, the SOC of battery 70 is more less than range of management Lower limit value, then ECU50 more by limit engine output P (low) from initial value to the correction for direction to become larger, to make conditional The width of continuous reproducible region B becomes smaller.
In addition, needing to generate the hair that driver requests output or more in the case where SOC is less than the lower limit value of range of management Motivation output, and charged using the output of the engine of redundance to battery 70.On the other hand, it is greater than management in SOC In the case where the upper limit value of range, due to that can not charge again to battery 70, thus the power generation of ISG40 will limit.
Upon step s 2, ECU50 judges whether to can be carried out the regeneration (step S3) of GPF29B.Here, referring to shown in Fig. 4 Regeneration treatment mapping, when can make engine 20 when conditional continuous reproducible region or continuous reproducible region operate, ECU50 is judged as the regeneration that can be carried out GPF29B.
When being judged as in the regenerated situation that not can be carried out GPF29B in step s3, ECU50 return step S2.Another party Face, when being judged as in the regenerated situation that can be carried out GPF29B in step s3, ECU50 implements GPF Regeneration control (step S4).
GPF Regeneration control is to increase the temperature of exhaust gas by improving engine output and made using the exhaust gas of high temperature GPF29B carries out regenerated movement.The details of GPF Regeneration control is aftermentioned.
Next, ECU50 judges whether the regeneration of GPF29B terminates (step S5), do not have in the regeneration for being judged as GPF29B Return step S2 in the case where end terminates this movement in the case where being judged as the regeneration ending of GPF29B.
In the following, illustrating the details of the GPF Regeneration control of step S4 referring to Fig. 3.
In Fig. 3, ECU50 is determining and updates conditional continuous reproducible region (step S11).Next, ECU50 judges Whether 3 conditions are all set up below: speed is greater than regulation vehicle velocity V (a)；Accelerator opening is greater than regulation accelerator opening Th (a)；And gear is traveling gear (step S12).In step S12, ECU50 is the case where this 3 conditions are all set up Under be judged as YES, be not all of set up in the case where be judged as NO.
In addition, accelerator opening be less than regulation accelerator opening Th (a) and engine 20 be in idling mode the case where Under, it is determined as in step s 12 no.If implementing the regeneration of GPF29B in the idling state, engine 20 becomes the shape that dallies State, in addition, starting performance (accelerating ability etc.) can be hindered.Therefore, idling mode is excluded from the regeneration implementation condition of GPF29B.
ECU50 terminates this movement in the case where being judged as NO in step s 12, in the case where being judged as YES, determination is driven The person of sailing requests output P (dr) (step S13).Here, it is that driver passes through accelerator operation to vehicle that driver, which requests output P (dr), The outputs of 10 requests.
ECU50 determines that driver requests output P (dr) according to accelerator opening etc..In the present embodiment, it is contemplated that battery 70 SOC etc. determines that engine output and ISG output request output to meet driver.
Next, whether it is P that ECU50 judges that driver requests the relationship of output P (dr) and upper limit engine output P (height) (dr) >=P (height) (step S14).When P (dr) >=P (height) in step S14 (when being in step S14), ECU50 is obtained Take the SOC (step S15) of battery 70.
Next, ECU50 judges any one whether true (step in SOC < SOC (low) or SOC (height) < SOC S16).Here, SOC (low) refers to the lower limit value (such as 30%) of the range of management of SOC.
SOC (height) refers to the upper limit value (such as 70%) of the range of management of SOC.
That is, whether ECU50 judge SOC below the lower limit value of range of management or greater than management in step s 16 The upper limit value of range.
ECU50 is in step s 16 in the case where SOC is not up to the lower limit value of range of management or greater than range of management Be judged as YES in the case where upper limit value, SOC be greater than range of management lower limit value and in the upper limit value of range of management it is below In the case of be judged as NO.
ECU50 in the case where being judged as YES, sets target engine output P (eg) in step S16 in step S17, And correct limit engine output P (low).In step S17, ECU50 by target engine output P (eg) be set as with The value that driver requests output P (dr) different.In the case where the charged state of battery 70 is greater than the upper limit value of range of management, by In can not to battery 70 further charge, therefore ECU50 by limit engine output P (low) be set as target engine export P(eg).And on the other hand, battery 70 charged state be range of management lower limit value situation below under, need to battery 70 chargings.In this case, due to that can be generated electricity in ISG40 using the redundance that engine exports, Upper limit engine output P (height) is set as target engine output P (eg) by ECU50.In addition, the charged state in battery 70 exists In the case where in range of management, upper limit engine output P (height) is set as target engine output P (eg), is enabled to It is generated for the regenerated heat of GPF29B and the electric power for charging for ISG40 using the engine output of redundance. In addition, limit engine output P (low) is corrected from initial value referring to Fig. 5, ECU50, so that conditional can in step S17 The width of cyclic regeneration region B is corresponding with the charged state of battery 70.For example, due to charged state be range of management under In the case where the width that reduce conditional continuous reproducible region B below limit value, ECU50 is from initial value to increased direction (right direction of Fig. 4) corrects limit engine output P (low).And on the other hand, range of management is being greater than due to charged state Upper limit value and in the case where reducing the width of conditional continuous reproducible region B, ECU50 does not export P to limit engine (low) carries out increase correction, but is maintained initial value.After implementation steps S17, ECU50 enters step S18.In step In the case where being judged as NO of S16, ECU50 enters step S18 without implementation steps S17.
In step S18, ECU50 determines that target ISG exports P (isg).Target ISG output P (isg) refers to that ISG40 is exported Target value.In detail, in step S18, ECU50 is defeated by subtracting driver's request from target engine output P (eg) Out P (dr) come determine target ISG export P (isg).
Next, ECU50 controls engine to generate the target engine set in step S17 output P (eg), and control ISG40 processed terminates this movement to generate the target ISG determined in step S18 output P (isg) (step S19).
In this way, in the present embodiment, it, can when P (dr) >=P (height) in step S14 (when being in step S14) Target engine output P (eg) is set greater than driver and requests output P (dr), and the excess portion that engine exports is set up separately It is set to target ISG output P (isg).
To make the heat of exhaust gas increase by increasing target engine output P (eg), GPF29B can be made to be warming up to It can regenerated temperature.It is recycled in addition, the engine of redundance can be exported as electric energy, can be improved fuel efficiency.
On the other hand, when in step S14 not being P (dr) >=P (height) while being no (in step S14), ECU50 will drive The person of sailing requests output P (dr) to be set as target engine output P (eg) (step S20), implementation steps S19.
That is, ECU50 controls engine 20, so that being only just able to satisfy driver by engine output requests output P (dr).This is because GPF29B liter only can be made by engine output at this time in the case where P (dr) >=P (height) is set up Temperature arrives can regenerated temperature.In addition, ECU50 is without the power generation that is carried out by ISG40.This is because not generating redundance Engine output.
As described above, in the present embodiment, be previously stored in ECU50 define the engine output of engine 20 with The regeneration treatment of the correlation of GPF temperature maps.
In addition, being set with ceiling temperature line L (height) and lower limit temperature line L (low), the above-mentioned upper limit in regeneration treatment mapping Temperature line L (height) is linked to be by the maximum temperature for corresponding to the GPF29B of engine output, and above-mentioned lower limit temperature line L (low) is What the minimum temperature by corresponding to the GPF29B of engine output was linked to be.
Also, (the step S1 of Fig. 2 is yes making GPF29B start regenerated regulation regeneration beginning condition establishment by ECU50 Situation), and engine 20 can regeneration treatment mapping in be located at ceiling temperature line L (height) and lower limit temperature line L (low) it Between region in, engine output range be set to include lower limit regenerative temperature conditional continuous reproducible region B When being operated the case where (the step S3 of Fig. 2 be being), make engine 20 among conditional continuous reproducible region B, GPF Temperature is that the region B1 of lower limit regenerative temperature or more is operated (the step S4 of Fig. 2).
To the case where regenerating the establishment of beginning condition and engine 20 can be in conditional continuous reproducible region B operating Under, by operating region B1 of the engine 20 more than the lower limit regenerative temperature among conditional continuous reproducible region B, energy The enough regeneration for continuously carrying out GPF29B.In addition, the operation range of the engine 20 in the Regeneration control of GPF29B is limited at In the B1 of region, ignition timing will not postpone significantly, therefore, can prevent from increasing noise and vibration due to ignition timing retard And fuel efficiency performance decline.
In addition, can prevent the GPF temperature in the regeneration of GPF29B from falling to not up to lower limit regenerative temperature.In addition, by Then GPF temperature is set as lower limit regenerative temperature rather than the temperature of exhaust gas is set as lower limit regenerative temperature, it therefore, can Prevent from generating the temperature position lower than lower limit regenerative temperature due to gas flow distribution in GPF29B etc., can prevent by In the low temperature position generation and deteriorate GPF29B.
As a result, the noise of engine 20 and vibration increase and fuel in the regeneration actions of GPF29B can be prevented The decline of efficiency performance.
In addition, in the present embodiment, vehicle 10 includes ISG40, generated electricity using engine output；And battery 70, the electric power that storage ISG40 is generated.
In addition, being located at starting for lower limit regenerative temperature and the intersection point C of lower limit temperature line L (low) in regeneration treatment mapping Machine output is set to upper limit engine output P (height), and it is conditional continuous reproducible region which, which exports P (height), The upper limit value of engine output in B.
In addition, being located at starting for lower limit regenerative temperature and the intersection point D of ceiling temperature line L (height) in regeneration treatment mapping Machine output is set to the initial value of limit engine output P (low), and it is that conditional can be continuous which, which exports P (low), The lower limit value of engine output in regeneration zone B.
Also, requesting output in the driver that driver requests to vehicle 10 is that limit engine exports P (low) or more simultaneously And exported in P (height) situation below for upper limit engine, ECU50 carries out engine 20 with upper limit engine output P (height) Operating, and the poor corresponding power generation torque for making ISG40 to export with upper limit engine output P (height) and driver's request into Row power generation.
Also, with from ISG40 with the torque that generates electricity generated electricity brought by, the charged state of battery 70 is to regulation management The upper limit value side of range increases, and limit engine output P (low) is corrected by ECU50 from initial value to increased direction.
That is, as in the range (11) shown in range of management in Fig. 5, increase with from charged state to upper limit value side, Limit engine output P (low) in Fig. 4 is corrected by ECU50 from initial value to increased direction.
To which lower limit can be securely maintained again by operating engine 20 with upper limit engine output P (height) Raw temperature, can suitably carry out the regeneration of GPF29B.
In addition, due to that driver can be requested output and the output difference of upper limit engine output P (height) return as electric energy It receives in battery 70, therefore, is able to suppress the deterioration of fuel efficiency.
In addition, in the case where operating engine 20 with upper limit engine output P (height), due to without carrying out a little Delay of fiery timing etc. can make GPF29B reach lower limit regenerative temperature, therefore, can reduce the fuel consumption of engine 20.
In addition, in the case where the charged state of battery 70 has reached the upper limit value of defined range of management, due to can not Charge again to battery 70, it is therefore desirable to terminate regeneration actions, still, by by limit engine output P (low) from initial It is worth to increase side and is corrected to reduce conditional continuous reproducible region B, regeneration actions can be promoted and charges to battery 70 Stopping.
In addition, in the present embodiment, ECU50 makes to send out in the case where charged state is not up to the lower limit value of range of management Motivation 20 is operated with upper limit engine output P (height).Moreover, starting from initial value to increased correction for direction lower limit In the case that machine exports P (low), charged state is lower, then ECU50, which is got over, exports P (low) to return initial value for limit engine Direction changes.
That is, in the case that charged state is in not up to region (10) of the lower limit value of range of management in Fig. 5, ECU50 operates engine 20 with upper limit engine output P (height) of Fig. 4.Moreover, from initial value to increased side In the case where correcting limit engine output P (low), in the region (10) of Fig. 5, charged state is lower, then ECU50 is got over Limit engine output P (low) is changed to the direction for returning to initial value.
To in the case where charged state is not up to the lower limit value of range of management, by sending out engine 20 with the upper limit Motivation output P (height) is operated, and increase delivery temperature and suitably increase GPF temperature.
In addition, driver can be requested to export by operating engine 20 with upper limit engine output P (height) It recovers energy with the output difference of upper limit engine output P (height) as the power generation torque of ISG40, therefore, is able to suppress fuel Efficiency deteriorates with regeneration actions.
In addition, when operating engine 20 with upper limit engine output P (height), due to without carrying out ignition timing Delay etc. GPF29B can be made to reach lower limit regenerative temperature, therefore, the fuel consumption of engine 20 can be reduced.
In addition, in the case where exporting P (low) to increased correction for direction limit engine from initial value, charged state It is lower, then more limit engine output P (low) is changed to the direction for returning to initial value, thus, and by limit engine The output direction P (low) Xiang Zengjia has carried out timing and has compared, and conditional continuous reproducible region B expands, and is able to suppress again lively The stopping made and charged to battery 70.
In addition, in the present embodiment, ISG40, which has, assigns complementary driving force to engine 20 using the electric power of battery 70 Function, ECU50 charged state be more than range of management upper limit value in the case where, export engine 20 with limit engine P (low) is operated.
