So set the rotating speed of target Ne of engine 22 ^*With target torque Te ^*, motor M G1 rotating speed of target Nm1 ^*With torque command Tm1 ^*, motor M G2 torque command Tm2 ^*After, with the rotating speed of target Ne of engine 22 ^*With target torque Te ^*Transmit to Engine ECU 24, simultaneously, with the rotating speed of target Nm1 of motor M G1 ^*With torque command Tm1 ^*And the torque command Tm2 of motor M G2 ^*Transmit (step S210) to motor ECU40, finish the drive controlling routine.Accept rotating speed of target Ne ^*With target torque Te ^*Engine ECU 24 carry out fuel injection control in the engine 22 and IGNITION CONTROL etc. so that engine 22 is by rotating speed of target Ne ^*With target torque Te ^*Shown working point running.In addition, accept rotating speed of target Nm1 ^*With torque command Tm1 ^*, torque command Tm2 ^*Motor ECU40 with at torque command Tm1 ^*In the time of following drive motors MG1, at torque command Tm2 ^*The mode of following drive motors MG2 is carried out the switch control of the switch element of inverter 41,42.

In step S120, be judged to be and require power P e ^*When threshold value Pref is following, be judged to be the motor rotation pattern, shutting engine down 22 (step S220) when engine 22 runnings is with the torque command Tm1 of motor M G1 ^*Be set at numerical value 0 (step S230), afterwards, the processing of execution in step S180～S210.

In step S130, be judged to be engine 22 when being in not operating condition, will require sign Fout be set at numerical value 1 (step S240) above output, the torque T cr that the turning crankshaft of engine 22 is used is set at the torque command Tm1 of motor M G1 ^*(step S250).Then, judge that whether the rotational speed N e of engine 22 is greater than threshold value Nref (step S260).The rotating speed of engine 22 is when threshold value Nref is following, the processing of execution in step S180～S210, when the rotational speed N e of engine 22 is bigger than threshold value Nref, (step S270) such as the fuel injection control of beginning engine 22 or IGNITION CONTROL, the processing of execution in step S180～S210.At this, threshold value Nref is set at the rotating speed of the engine 22 of beginning fuel injection control or IGNITION CONTROL, for example 800rpm or 1000rpm etc.

More than, drive controlling has been described.As above-mentioned, in this drive controlling, when accelerator pedal aperture Acc is bigger than threshold value A ref or piloted engine 22 o'clock, above output require sign be set to numerical value 1 (step S150, S240).In addition, in drive controlling, set the torque command Tm2 of motor M G2 ^*When, the export-restriction Wout (step S180) of use storage battery 50.Below, the management of the export-restriction Wout of the storage battery 50 that uses in the drive controlling like this is described.

During the illustrative supervisory routine of execution graph 3, storage battery ECU52 at first, carry out input from the voltage Vb of voltage sensor 51a or from the current Ib of current sensor 51b, from temperature sensor 51 battery temperature Tb, residual capacity (SOC), surpass the processing (step S300) that output requires the outgoing management institute necessary data of storage batterys 50 such as sign Fout.At this, for residual capacity (SOC), the numerical value that the specified address input of not shown RAM by storage battery ECU52 is obtained by the integrating current Ib requires sign Fout for surpassing output, transmits input with electronic control unit 70 by communication from hybrid power.

After importing data like this,, set the export-restriction Wout (step S310) of storage battery 50 according to the battery temperature Tb and the residual capacity (SOC) of input.At this, the export-restriction Wout of setting pre-determines as the specified output of storage battery 50, can set according to the temperature characterisitic of relative storage battery 50 or the characteristic of residual capacity (SOC).Then, check whether will require sign Fout to be set at numerical value 1 (step S320) above output.As aforementioned, in drive controlling, when accelerator pedal aperture Acc is bigger than threshold value A ref, or piloted engine 22 o'clock, require sign Fout to be set to numerical value 1 above output.When requiring sign Fout not to be set to numerical value 1 above output, finish the outgoing management routine.Therefore, export-restriction Wout is set in specified output for.

When surpassing output and requiring sign Fout to be set to numerical value 1, judge from the output that surpasses last time and handle the execution of (export-restriction Wout is set than the big output of specified output and up to the processing of the step S350～S410 that removes) and whether pass through stipulated time T1 (step S330).At this, stipulated time T1 sets as carry out surpassing the interval that output handles, and can or allow that the size etc. of the output that surpasses determines by the performance of storage battery 50.During from surpassing execution that output handles and do not pass through stipulated time T1 last time, be judged as should not carry out and surpass output and handle,, finish the outgoing management routine at this.At this moment, specified output also is set at export-restriction Wout.

From last time surpass execution that output handles through stipulated time T1 the time, judge from beginning current surpass output and handle whether pass through stipulated time T2 (step S340).At this, stipulated time T2 surpasses the binding hours that output handles and sets as carrying out continuously, can or allow that the size etc. of the output that surpasses determines by the performance of storage battery 50.When not passing through stipulated time T2, by amassing of voltage Vb and current Ib, the output Wb (step S350) of calculating accumulator 50 calculates its deviation with the export-restriction Wout that sets as specified output, exports Δ W (step S360) as surpassing.Then, calculate surpass output Δ W be on the occasion of the time (step S370), the numerical value that integrating should multiply each other above the starting Δ blanking time t (being 8msec in an embodiment) of output Δ W and outgoing management routine, to calculate output ENERGY E b (step S380), the output ENERGY E b that calculates is compared (step S390) with threshold value Eref.That is, carry out time integral to beginning to surpass the output Δ W that surpasses that exports the specified output of having handled, surpass storage battery 50, this integrated value compares with threshold value Eref as output ENERGY E b.At this, threshold value Eref is for judge surpassing the numerical value that the output processing finishes, and the output that will surpass the specified output of storage battery 50 is set as the energy that can carry out in the scope, can be definite by the performance of storage battery 50.During output ENERGY E b deficiency threshold value Eref, be judged as and continue to surpass the output processing, the export-restriction Wout that sets specified output adds as surpassing of the regulation of allowing the output that surpasses exporting Wset, being set and is new export-restriction Wout (step S400), finishes the outgoing management routine.At this, the output Wset that surpasses of regulation sets the upper limit output that can surpass specified output ground output from storage battery 50, can be determined by the performance of storage battery 50.After will requiring sign Fout to be set at numerical value 1 above output, when carrying out this outgoing management routine, specified output is set at export-restriction Wout, in drive controlling, owing to set the torque command Tm2 of motor M G2 in the limited field of the export-restriction Wout that sets this specified output ^*, surpass output Δ W not can on the occasion of.And, because export-restriction this moment Wout adds that the setting value that surpasses output Wset of regulation is export-restriction Wout, when carrying out drive controlling thereafter, can a torque command Tm2 that output Wset makes motor M G2 that surpasses with regulation ^*Set greatlyyer.So just the permission that surpasses that surpasses output Wset of regulation makes starting blanking time of only sluggish outgoing management routine, but since in an embodiment this time be 8msec, the driver can not feel this time lag.

In addition,, when threshold value Eref is above, in order to finish to surpass outgoing management, when output ENERGY E b is set at numerical value 0, surpasses output and require sign Fout to be set to numerical value 0 (step S410), end outgoing management routine at output ENERGY E b.In addition, in the present embodiment, requiring sign Fout to be set at the setting of 0 value to surpassing output, is to realize to the output of hybrid power with electronic control unit 70 by from storage battery ECU52 control signal being transmitted through communication.In addition,, in step S330, be judged as from beginning specifically when surpassing output and handling, finish to surpass the output processing too through stipulated time T2 even output ENERGY E b does not reach threshold value Eref.

Fig. 7 illustrates when starting driver 83 more for a long time key diagrams of accelerator pedal aperture Acc and an example of the time variation of the output Wb of storage battery 50 to put one's foot down.83 more to put one's foot down, sets according to correspondingly accelerator pedal aperture Acc and require power P e ^*, requiring power P e ^*Greater than threshold value Pref and piloted engine 22 o'clock, require sign Fout to be set to numerical value 1 owing to surpass output, for the export-restriction Wout of storage battery 50, become the numerical value of exporting Wset that surpasses that specified output adds regulation.Output and turning crankshaft motor M G1 due to and sharply rise of the output Wb of storage battery 50 by motor M G2 surpasses specified output, but owing to reverses instruction Tm2 by what export-restriction Wout had limited motor M G2 ^*So, can not surpass export-restriction Wout (Wset is exported in surpassing of specified output+regulation).During engine 22 startings, because by motor M G1 generating, the output Wb of storage battery 50 temporarily reduces from the output of engine 22, but continue more ground to put one's foot down 83 by the driver, vehicle velocity V uprises, and the output Wb of storage battery 50 becomes export-restriction Wout once more.Therebetween, storage battery ECU52 is the outgoing management routine of execution graph 3 repeatedly, and calculates the output ENERGY E b as the time integral that surpasses output Δ W.Among Fig. 7, the zone of giving shade of " storage battery output Wb " is equivalent to export ENERGY E b.When this output ENERGY E b reached threshold value Eref, export-restriction Wout returned specified output.

Hybrid vehicle 20 according to the present embodiment of above explanation, since up to the specified output that surpasses storage battery 50, reach threshold value Eref as the output ENERGY E b of the time integral that surpasses output Δ W till, all the output that specified output one regulation of only surpassing of storage battery 50 can be surpassed output Wset is set at export-restriction Wout, and drive controlling motor M or motor M G2 etc. in the limited field of export-restriction Wout, thereby can further bring into play the performance of storage battery 50.As a result, can improve the performance of vehicle.And, when beginning so rises through stipulated time T2 above the execution of exporting processing, even, also finish to surpass output and handle, can suppress to surpass the phenomenon that the output of the specified output of storage battery 50 is carried out for a long time because output ENERGY E b does not reach threshold value Eref.

In the hybrid vehicle 20 of present embodiment, when beginning to surpass execution that output handles and rising,, also finish to surpass output and handle, even also harmless but do not carry out time restriction like this even output ENERGY E b does not reach threshold value Eref through stipulated time T2.

In the hybrid vehicle 20 of present embodiment, when accelerator pedal aperture Acc is bigger than threshold value A ref or piloted engine 22 o'clock, use from storage battery 50 output can surpass specified output, as the regulation of upper limit output surpass output Wset, but also can use the regulation of setting according to the temperature of accelerator pedal aperture Acc or storage battery 50 to surpass output Wset.In addition, in the hybrid vehicle 20 of present embodiment, surpass the binding hours that output is handled, used stipulated time T2, set stipulated time T2 but also can use according to the temperature of accelerator pedal aperture Acc or storage battery 50 as carrying out continuously.Under situation like this, export and binding hours the calculating that much less also can not export ENERGY E b owing to can only consider to surpass.To illustrate among the 2nd embodiment below for this structure.
