In the vehicle 1 with this construction as described above, regeneration allowable temperature model is increased in the temperature of filter 84 In the case of in enclosing, the PM being deposited at filter 84 is burned, and burning things which may cause a fire disaster occurs.In this case, if by proper amount of Air is supplied to filter 84, then can promote the burning of PM.However, even if when filter temperature Tf is in the regeneration of filter 84 When in allowed temperature range, stop fuel spray if executed in the case of lower limiting values of the filter temperature Tf close to temperature range It penetrates and so that the output shaft of engine 10 is rotated to supply air to the operation of filter 84 using the first MG 20, then excessively supply The air given also weakens the burning things which may cause a fire disaster at filter 84.Accordingly, there exist following situation, i.e. filter temperature Tf is fallen below again The lower limiting value of raw allowed temperature range.Less than the combustion that the filter temperature Tf of the lower limiting value of regeneration allowed temperature range does not promote PM It burns.Therefore, because the temperature raising of filter temperature Tf caused by the burning of regeneration PM at filter is further reduced.

Therefore, this embodiment is characterized in that, it is regenerated in filter 84, when filter temperature Tf be less than conduct When (1) predetermined temperature Tf of threshold value, ECU 200 controls the first MG 20 alternately to repeat the first control (motoring control) With the second control, first control is turned in the state of stopping fuel injection in engine 10 using the output of the first MG 20 Square makes the output shaft of engine 10 rotate, and second control stops the generation of the output torque of the first MG 20.Described below In, alternately repeatedly the operation of the first control and the second control is described as " interval motoring ", and continues the first control Operation be described as " continuous motoring ", and execute first control period be described as " motoring period ", and And the period for executing the second control is described as " motoring stops the period ".

In addition, in the case where regenerating filter 84, when filter temperature Tf is higher than (1) predetermined temperature Tf, ECU 200 The first MG 20 is controlled to execute continuous motoring, until the regeneration of filter 84 is completed.

In addition, the intake air temperature Ti and extraneous air of filter temperature Tfs of the ECU 200 based on engine 10, engine 10 At least one of temperature To temperature determines that motoring period and motoring stop the period at least one of period.

Fig. 2 is to indicate to be mounted on the functional-block diagram according to the ECU 200 on the vehicle 1 of the present embodiment.ECU 200 includes Regeneration requirements determination unit 202, temperature determining unit 204, period determination unit 206, motoring control device 208 and completion Determination unit 210.

Regeneration requirements determination unit 202 determines whether the regeneration of requirement filter 84.It is described above for determining Whether the regeneration method of filter 84 is required.Therefore, it detailed description thereof will not be repeated.

Temperature determining unit 204 determines whether filter temperature Tf is in first more than or equal to predetermined temperature Tf (1) In temperature range, whether filter temperature Tf is in the lower limiting value Tf (0) for being greater than or equal to regeneration allowed temperature range and is less than Equal to predetermined temperature Tf (1) second temperature within the scope of or filter temperature Tf whether in be less than regeneration allowable temperature model In the third temperature range of the lower limiting value Tf (0) enclosed.

Predetermined temperature Tf (1) is the high values of lower limiting value Tf (0) of the regeneration allowed temperature range than filter 84.Pre- constant temperature Tf (1) is spent to be set so that, even if in the case where the first control continuously performs until the regeneration of filter 84 is completed, Filter temperature Tf do not fall yet filter 84 regeneration allowed temperature range lower limiting value Tf (0) below.

Determine that requiring the regeneration of filter 84 and temperature determining unit 204 to determine filters in regeneration requirements determination unit 202 In the case that device temperature Tf is within the scope of second temperature, period determination unit 206 determines motoring period and motoring Stop each period in the period.

Period determination unit 206 is based on such as filter temperature Tf (particularly, the measured values of filter temperature Tf and predetermined Difference between temperature Tf (1)), at least one of intake air temperature Ti and external air temperature To temperature is when determining motoring Section and motoring stop the period.

When for example at least one of filter temperature Tf, intake air temperature Ti and external air temperature To temperature are relatively low, Period determination unit 206 can determine the motoring period so that the motoring period is shortened to reduce in the motoring period The reduction amount of filter temperatures Tf.

In addition, such as at least one of filter temperature Tf, intake air temperature Ti and external air temperature To temperature compared with When low, period determination unit 206 can determine that motoring stops the period so that elongated segment is to increase filtering when motoring stops The rise of device temperature Tf.

Determined in motoring period and motoring stopping period, the determination of period determination unit 206 refers to Show the interval number of the number of the control of repetition first and the second control.Period determination unit 206 is based on the PM at such as filter 84 Deposition determines the supply amount of the air required by burning PM.Period determination unit 206 is calculated for supplying identified supply The amount required motoring period.Period determination unit 206 calculates the number of motoring period so that the motoring period Summation be more than calculate the motoring period.Interval number can be predetermined value.

In the present embodiment, when describing period determination unit 206 and not changing motoring period and motoring and stop Until determining interval number is repeated in Duan Zhizhi motoring periods and motoring stopping period.However, for each It has a rest motoring, motoring period and motoring, which stop the period, can be based on filter temperature Tf, intake air temperature Ti and outside At least one of air themperature To temperature changes.

In addition, for example, in the construction of hybrid vehicle shown in Fig. 1, it is expected that period determination unit 206 is made to examine Revolution (is increased to the time of predetermined number of revolutions, or stops generation in the output torque of the first MG by the response for considering the first MG 20 The revolution of engine 10 is set to become for zero time afterwards) determine that motoring period and motoring stop the period.For example, it is desirable to Motoring is stopped into slot setup at making the revolution (do not become zero) of engine 10 stop generating from the output torque of the first MG Continue to next motoring period.By this method, the rotating speed of engine 10 can promptly rise during the motoring period Height arrives desired speed.

In the case of at temperature determining unit 204 determines filter temperature Tf in the first temperature range, motoring Control device 208 executes continuous motoring.In other words, motoring control device 208 is used for based on the deposition determination of PM The motoring period of the supply burning required amount of air of PM, and the first MG 20 is controlled to use the first MG 20 to execute electricity Dynamic revolution, until by the determining continuous motoring period.At this point, motoring control device 208 controls engine 10 to stop the fuel injection to engine 10.

The regenerated of filter 84, motoring control dress are not required after by the continuous motoring period Set the continuous motoring of 208 completions.At this point, motoring control device 208 controls engine 10 to restore to engine 10 Fuel injection.In addition, the regenerated of filter 84 is still required that after even across the continuous motoring period, it is electronic Rotation control device 208 executes continuous motoring again.

In the case where temperature determining unit 204 determines that temperature of transmission Tf is within the scope of second temperature, motoring Control device 208 executes interval motoring.In other words, motoring control device 208 controls the first MG 20, with according to logical The motoring period for crossing the determination of period determination unit 206 executes the first control, stops period execution second according to motoring Control, and the first control and the second control are alternately repeated by determining interval number.

The case where not requiring the regeneration of filter 84 after alternately repeating the first control and the second control with interval number Under, motoring control device 208 completes interval motoring.At this point, motoring control device 208 control engine 10 with Restore the fuel injection to engine 10.In addition, being wanted after alternately repeating the first control and the second control by interval number Ask filter 84 it is regenerated in the case of, motoring control device 208 executes interval motoring again.

It completes determination unit 210 and determines whether the regeneration of filter 84 is completed.Determination unit 210 is completed by using upstream Side pressure sensor 90 and downstream side pressure sensor 92 determine whether the regeneration of filter 84 is completed.

Particularly, in the upstream side pressure detected by upstream side pressure sensor 90 and pass through downstream side pressure sensing For difference between the downstream lateral pressure that device 92 detects less than in the case of threshold value, completion determination unit 210 determines filter 84 Regeneration complete.

For determining that threshold value that whether regeneration of filter 84 is completed can be the predetermined value by testing or designing adaptation, Or it can be changed according to the operating status of engine 10.

In addition, being used to determine that the threshold value whether regeneration of filter 84 is completed can be and be used to determine whether to require filtering The identical value of regenerated threshold value of device 84, or can be than being used to determine whether to require that the regenerated threshold value of filter 84 is small Value.

In the present embodiment, it has described motoring control device 208 and has executed continuous motoring until by continuous electricity Until the dynamic revolution period, therefore to execute continuous motoring until the regeneration of filter 84 is completed.However, for example holding During the continuous motoring of row, continuous motoring is executable until completing determination unit 210 determines that the regeneration of filter 84 is complete As only.

With reference to figure 3, by description by being mounted on the control process executed according to the ECU 200 on the vehicle 1 of the present embodiment. For example, after the system of vehicle 1 starts, ECU 200 executes process control as follows.

In step (hereinafter step will be simply referred to as S) 100, ECU 200 determines whether the regeneration of requirement filter 84.When Determine that process proceeds to S102 when requiring regeneration (being yes in S100) of filter 84.If not requiring (being no in S100), This process terminates.For example, requiring the regenerated of filter 84, ECU 200 that can open regeneration requirements in the determinations of ECU 200 Mark.

In S102, whether 200 temperature Tf of ECU locate (in other words, to be in the first temperature range and be more than or wait In the range of predetermined temperature Tf (1)).When determining (being yes in S102) in the first temperature range at filter temperature Tf, Process proceeds to S104.If being not located in the first temperature range (being no in S102), process proceeds to S110.For example, When at filter temperature Tf in the first temperature range, ECU 200 can open the first temperature and determine mark.

In S104, ECU 200 executes continuous motoring.Because continuous motoring will be as described above, will not weigh Its multiple detailed description.For example, when regeneration requirements mark and the first temperature determine mark in open state, ECU 200 can be held The continuous motoring of row.

In S106, ECU 200 determines whether the regeneration of requirement filter 84.When the determining regeneration for requiring filter 84 When (being yes in S106), process returns to S104.If not requiring (being no in S106), process proceeds to S108.

In S108, ECU 200 terminates motoring (continuous motoring or interval motoring).In S110, ECU 200 determine whether (in other words, temperature is allowed in the regeneration more than or equal to filter 84 to filter temperature Tf in second temperature range Spend the lower limiting value Tf (0) of range and the temperature range less than predetermined temperature Tf (1)) in.When determining that filter temperature Tf is in the In two temperature ranges when (being yes in S110), process proceeds to S112.(it is in S110 if be not within the scope of second temperature It is no), then this process terminates.For example, when filter temperature Tf is within the scope of second temperature, ECU 200 can open the second temperature Degree determines mark.

In S112, ECU 200 is based on temperature condition (in filter temperature Tf, intake air temperature and external air temperature At least one temperature), determine that motoring period and motoring stop the period.

In S114, ECU 200 executes interval motoring.Interval motoring is as described above.Therefore, it will not be repeated Detailed description.When regeneration requirements mark and second temperature determine mark all in open state, the executable interval electricity of ECU 200 Dynamic revolution.

In S118, ECU 200 determines whether the regeneration of requirement filter 84.When the determining regeneration for requiring filter 84 When (being yes in S118), process proceeds to S118.If not requiring (being no in S118), process proceeds to S108.For example, After completing motoring (continuous motoring or interval motoring) by motoring control device 208, ECU 200 can Determine whether the regeneration (in other words, if complete the regeneration of filter 84) of requirement filter 84, and filter ought not be required When 84 regeneration (in other words, when the regeneration completion for determining filter 84), regeneration requirements mark is closed.

In S120, whether ECU 200 determines filter temperature Tf in the first temperature range.When determining filter temperature When degree Tf is in the first temperature range (being yes in S120), process proceeds to S104.If be not in the first temperature range (being no in S120), then process proceeds to S114.

By being mounted on according to the present embodiment based on structure and flow chart explained above with reference to figure 4 and Fig. 5 descriptions The operation of ECU 200 on vehicle 1.

As shown in FIG. 4, at moment T (0), when the regeneration (being yes in S100) and filter for requiring filter 84 When temperature Tf is in the first temperature range (being yes in S102), continuous motoring (S104) is executed.

Therefore, from moment T (0) to moment T, (1) is consecutively carried out motoring, by continuous at the moment T (1) The motoring period.Because a large amount of air is supplied to filter 84, filter by being consecutively carried out motoring Temperature Tf was once reduced.However, because the burning things which may cause a fire disaster at filter 84 is strong, promotes the burning of PM by supplying air, make The process obtained at any time is elevated the temperature by the heat etc. of burning.At filter 84, the heavy of PM is reduced by the burning of PM Accumulated amount.

At moment T (1), if not requiring the regeneration (being no in S106) of filter 84, continuous motoring is completed (S108)。

On the other hand, as shown in FIG. 5, at moment T ' (0), when the regeneration (being yes in S100) for requiring filter 84 And when filter temperature Tf is within the scope of second temperature (being yes in being no in S12 and S110), determined based on temperature condition Motoring period, motoring stop period and interval number (S112) and execute interval motoring (S114).

Therefore, motoring is executed from moment T ' (0) to by T ' (1) at the time of the determining motoring period.Hereafter, Stop motoring at the time of stopping the period by motoring until T ' (2), and engine 10 becomes in operation Under state.At this point, with the beginning of motoring, rotary force is assigned to the output shaft of engine 10 by the first MG 20 so that hair The rotating speed of motivation 10 reaches desired speed, and stops by stopping motoring the generation of the output torque of the first MG 20 (in other words, stopping assigning rotary force to the output shaft of engine 10).Such operation is repeated prepause number (in Figure 5 It it is seven times).In the motoring period for executing the first control, when air is fed into filter 84, filter temperature Tf drops It is low.However, because the supply of air to filter 84 stops during the subsequent motoring for executing the second control stops the period Only, and engine 10 reaches operating status, so the discharge heat of engine 10 makes the temperature of filter 84 increase.Because with this The mode of sample alternately repeats the first control and the second control is inhibited air oversupply to filter 84, so inhibiting The weakening of burning things which may cause a fire disaster at filter 84.Because the rise of filter temperature Tf is more than in electricity during motoring stops the period The reduction amount of filter temperature Tf during the dynamic revolution period, so making filter temperature Tf at any time by repeating increase and reduction Through raising.Therefore, it is suppressed that filter temperature Tf falls below the lower limiting value of regeneration allowed temperature range.Therefore, because To promote the burning of PM, so reducing the deposition of the PM at filter 84.

At the time of repeating after determining interval number at T ' (3), (it is in S116 when not requiring the regeneration of filter 84 It is no) when, interval motoring completes (S108).

In addition, at moment T ' (3), when the regeneration (being yes in S116) and filter temperature Tf that require filter 84 increase When (being yes in S118), continuous motoring (S104) is executed in the first temperature range.If filter temperature Tf stops (being no in S118) is stayed within the scope of second temperature, then executes interval motoring (S114).

In the above described manner, according to the hybrid vehicle of the present embodiment, in the case where regenerating filter 84, even if having served as Filter temperature Tf is less than predetermined temperature Tf (1), and by using first in the state of stopping fuel injection in engine 10 When oxygen-containing air is supplied to filter 84 by the first control that the output torque of MG 20 makes the output shaft of engine 10 rotate, Can by the generation of the output torque of subsequent the first MG 20 of stopping second control inhibit by air oversupply to filter Device 84 so that can inhibit the reduction of filter temperature Tf.In addition, because air can be by alternately repeating the first control and second Control is intermittently supplied to filter 84, so can promote the regeneration of filter while inhibit the reduction of filter temperature Tf. Therefore, it is possible to provide the hybrid vehicle for inhibiting filter regeneration simultaneously filter temperature to reduce.

In addition, in the case where regenerating filter 84, when filter temperature Tf is greater than or equal to (1) predetermined temperature T, ECU 200 controls the first MG 20 to continue the first control, until the regeneration of filter 84 is completed.Therefore, because can will be big The air of amount is supplied to filter 84, so by promoting the burning of PM to promote the regeneration of filter 84 can be complete in early stage At the regeneration of filter.

In addition, because ECU 200 can pass through intake air temperature Ti and extraneous air based on filter temperature Tf, engine 10 At least one of temperature To temperature determines that motoring period and motoring stop the period at least one of period to close Determine that motoring period and motoring stop the period suitablely, so can for example inhibit by executing interval motoring Filter temperature Tf falls below the lower limiting value of the regeneration allowed temperature range of filter 84.

ECU 200 can based in filter temperature Tf, the intake air temperature Ti of engine 10 and external air temperature To extremely A few temperature determines the continuous motoring period.

In addition, during motoring stops the period, by running engine 10 during motoring stops the period, The discharge heat of engine 10 can be used to increase filter temperature Tf for ECU 200.

When determining that filter temperature Tf is not within the scope of the first temperature range or second temperature (in other words, when determining Filter temperature Tf is in third temperature range) when, ECU 200 is executable to be risen above regeneration by filter temperature Tf and allows The temperature of at least lower limiting value Tf (0) of temperature range increases control, or may wait for, until filter temperature Tf passes through engine 10 Discharge heat rise above regeneration allowed temperature range at least lower limiting value Tf (0) until.

In the present embodiment, it has described for example, assuming that the operation as follows of engine 10, that is, requiring the regenerated of filter 84 In the case of, when filter temperature Tf is within the scope of second temperature, stop during the motoring period to engine 10 Fuel injection and execution motoring, and stop motoring and operation engine 10 during motoring stops the period.So And such as in the state of stopping to the fuel injection of engine 10 allow vehicle 1 only using the 2nd MG 30 as driving source row In the case of requiring filter 84 regenerated during the EV travelings sailed, and when filter temperature Tf is within the scope of second temperature When, it can perform interval motoring.In the case, during motoring stops the period, the combustion to engine 10 can be maintained Expect the halted state of injection, or engine 10 can be run.

In the present embodiment, it has described to determine that motoring period and motoring stop the period so that filter temperature Tf processes at any time and increase while by the increase and reduction of interval motoring duplication filter temperature.However, for example Motoring period and motoring stopping period can be identified as so that filter temperature Tf passes through interval motoring and repeats to increase Adduction reduces, nearby to increase and subtract in predetermined temperature range or in preset target temperature (for example, predetermined temperature Tf (1)) It is small.

<Second embodiment>

Hereinafter, hybrid vehicle according to second embodiment will be described.With vehicle according to above-mentioned first embodiment 1 construction is compared, according to the hybrid vehicle 1 of the present embodiment the drive system and ECU 200 of vehicle 1 operating aspect It is different.Other constructions are identical as the construction of vehicle 1 according to above-mentioned first embodiment.Identical part is assigned identical attached drawing Label.The function of these same sections is also identical.Therefore, it detailed description thereof will not be repeated.

As shown in FIG. 6, it (is hereinafter retouched including engine 10, dynamotor 22 according to the vehicle of the present embodiment 1 State as MG 22), automatic transmission 23, torque-converters 24, driving wheel 72 and hydraulic pressure control device 28.

K0 clutches 26 are arranged between the output shaft of engine 10 and the output shaft of MG 22.K0 clutches 26 are being sent out From the state switching in power delivery status and power off state between the output shaft and the output shaft of MG 22 of motivation 10 To another state.

Torque-converters 24 includes the pump impeller 24a for the output shaft for being connected to MG 22 and is connected to the input shaft of automatic transmission Turbine 24b.Guide wheel is arranged between pump impeller 24a and turbine 24b.The input shaft and output shaft of torque-converters 24 are by reaching engagement 25 synchronous rotary of lock-up clutch of state, and the lock-up clutch 25 by reaching release conditions cancels the synchronization rotated.

Automatic transmission 23 can be geared automatic transmission or contiuously variable transmission (CVT).

Hydraulic pressure control device 28 includes solenoid valve, which is configured for based on the control for example from ECU 200 Signal S3 come switch oil circuit etc. and control be supplied to lock-up clutch 25 oil pressure (engaging force of lock-up clutch 25) and supply It is given to the valve of the oil pressure (engaging force of K0 clutches 26) of K0 clutches 26.

In addition, hydraulic pressure control device 28 controls the transmission of automatic transmission 23 based on the control signal S3 from ECU 200 Gear ratio.

With reference to figure 7, the control process that description is executed by the ECU 200 on the vehicle 1 according to the present embodiment.

The S100 of flow chart shown in the process and Fig. 3 of the S200 and S100 to S118 of flow chart shown in fig. 7 is extremely The process of S118 is identical.Therefore, it detailed description thereof will not be repeated.

When determining (being yes in S102) in the first temperature range at filter temperature Tf, ECU 200 is controlled in s 200 The engaging force of K0 clutches 26 processed so that K0 clutches 26 reach engagement state (open state).After this, ECU 200 permits Perhaps process proceeds to S104.

When determining that temperature of transmission Tf is within the scope of second temperature (being yes in S110), ECU 200 is controlled in S202 The engaging force of K0 clutches 26 processed so that K0 clutches 26 reach engagement state (open state).After this, ECU 200 permits Perhaps process proceeds to S112.

It will be mounted on according to the ECU on the vehicle 1 of the present embodiment based on structure discussed above and flow chart description 200 operation.

When the regeneration (being yes in S100) and filter temperature Tf that require filter 84 are in (S102 in the first temperature range In be yes) when, the engaging force of K0 clutches 26 is controlled such that K0 clutches 26 reach engagement state (S200), and executes Continuous motoring (S104).

Therefore, motoring is consecutively carried out, until by the continuous motoring period.Because by continuously performing Motoring and a large amount of air is supplied to filter 84, so filter temperature Tf was once reduced.However, because passing through confession The burning for promoting PM to air, so the process of the temperature of filter 84 at any time passes through the raisings such as the heat of burning.In filter At 84, the deposition of PM is reduced by the burning of PM.

It is complete if not requiring the regeneration (being no in S106) of filter 84 after by the continuous motoring period At continuous motoring (S108).

On the other hand, when the regeneration (being yes in S100) and filter temperature Tf that require filter 84 are in second temperature model In enclosing when (be in no and S110 in S102 be yes), the engaging force for controlling K0 clutches 26 makes K0 clutches 26 reach joint shape State (S202), and determine that motoring period, motoring stop period and interval number, and hold based on temperature condition (S112) It in the ranks has a rest motoring (S114).

Therefore, motoring is executed, until by the predetermined motoring period, and it is straight then to stop motoring Until stopping the period by motoring, and engine 10 reaches operating status.At this point, the rotation generated by the first MG 20 Turn the output shaft that power is endowed engine 10 so that when starting motoring, the rotating speed of engine 10 reaches desired speed, and And the generation for stopping the output torque of the first MG 20 by stopping motoring (in other words, stops the output shaft to engine 10 Assign rotary force).Such operation is repeated prepause number.During the motoring period for executing the first control, work as sky When gas is fed into filter 84, filter temperature Tf is reduced.However, the motoring controlled in subsequent execution second stops Stop supplying air to filter 84 during period, and engine 10 reaches operating status so that the discharge heat of engine 10 It is increased Deng by the temperature of filter 84.Because being inhibited to mistake by alternately repeating the first control and the second control by this method 84 oversupply air of filter, so inhibiting the weakening of the burning things which may cause a fire disaster at filter 84.Because stopping phase period in motoring Between filter temperature Tf rise be more than during the motoring period filter temperature Tf reduction amount, so repeat increase Filter temperature Tf is increased with time going by while adduction reduces.Therefore, it is suppressed that filter temperature Tf is reduced to low In the lower limiting value of regeneration allowed temperature range.Therefore, because promoting the burning of PM, so reducing the heavy of the PM at filter 84 Accumulated amount.

After repeating prepause number, if not requiring the regeneration (being no in S116) of filter 84, interval is electronic (S108) is completed in revolution.

In the above described manner, according to the hybrid vehicle according to the present embodiment, in the case where regenerating filter 84, even if When filter temperature Tf is less than predetermined temperature Tf (1), and K0 clutches 26 reach engagement state, and by engine 10 Middle the first control for stopping making the output shaft of engine 10 rotate using the output torque of the first MG 20 in the state of injection fuel When oxygen-containing air is supplied to filter 84, it can also pass through the second of the generation of the output torque of subsequent the first MG 20 of stopping Control inhibits air oversupply to filter 84 so that can inhibit the reduction of filter temperature Tf.In addition, because can pass through It alternately repeats the first control and air is intermittently supplied to filter 84 by the second control, so the regeneration of filter can be promoted Inhibit the reduction of filter temperature Tf simultaneously.Therefore, it is possible to provide inhibit filter regeneration simultaneously filter temperature to reduce mixed Close power car.
