Data are imported into controller 12 via signal circuit respectively, and the detection of this accelerator pedal jaw opening sensor 13 is equivalent to accelerator pedal
The accelerator pedal aperture of the amount of treading in, the gear lever that this disconnect switch (inhibitor switch) 15 detection vehicle is possessed
Operating position.
Based on above structure, hybrid power drives electric automobile 20 to carry out the EV mould of the power merely with motor generator 1
The HEV mode that formula travels with the power using motor generator 1 and explosive motor 6 simultaneously travels.
When travelling to HEV mode traveling switching from EV pattern, make the first friction engagement element 5 and the second frictional engagement unit
Part 3 is sliding-modes, so that the motor torsional moment of motor generator 1 increases, and the most push-jump explosive motor 6.In this state
Under, explosive motor 6 is supplied fuel and makes explosive motor 6 start.
Start explosive motor 6 in travelling about EV pattern, be roughly divided into following two situation: driver treads in acceleration and steps on
The situation of plate, i.e. based on acceleration request situation, and reduce such as the charge volume of battery and need to carry out the situation of battery charging
Such situation based on system request.In the latter case, the driving force utilizing explosive motor 6 makes vehicle row
Sail, be driven battery is charged as electromotor using motor generator 1.This is independently carried out with acceleration request
Operation.
In the case of the degree of acceleration request is big, it is desirable to make the output moment of torsion of motor generator 1 increase rapidly, thus short
Start explosive motor 6 in time, make the input torque response to automatic speed variator 4 input increase well.On the other hand,
In the case of starting explosive motor 6 under the situation that the degree that there is not acceleration request or this acceleration request is little, in order to press down
The generation that brought impact is increased dramatically of the output moment of torsion of motor generator 1 processed, it is desirable to make the output of motor generator 1 turn round
Square increases lentamente.In order to meet this contrary request, controller 12 performs the engine start control routine shown in Fig. 2.
When with reference to Fig. 2, in the case of there is engine start request, perform this routine.
In step sl, controller 12 judges that the degree of acceleration request sent by driver is the biggest.Specifically, exist
Accelerator pedal aperture APO detected by accelerator pedal jaw opening sensor 13 exceedes regulation aperture or accelerator pedal aperture APO
In the case of increment rate exceedes fixing speed, it is judged that the degree of the acceleration request for being sent by driver is big.
In the case of the judgement of step S1 is affirmative, determine the target for setting motor generator 1 in step s 6
Parameter t of motor torsional moment, R, h, carry out target setting motor torsional moment based on parameter t, R, h.
Then, with reference to Fig. 3 D and Fig. 4 B, parameter t, R, h are illustrated.
When with reference to Fig. 3 D, the dotted line in figure is the common mesh treading in corresponding motor generator 1 with accelerator pedal
Mark motor torsional moment.As shown in this dotted line, even if in the case of not starting explosive motor 6, the target motor of motor generator 1
Moment of torsion also correspondingly increases with treading in of accelerator pedal.In the case of the engine start control routine performing Fig. 2, no matter walk
Rapid S1 determines how, and all utilizes the rotation torque of motor generator 1 to start explosive motor 6.To this end, such as the institute of A portion in figure
Showing, the target motor the most additionally increasing the motor generator 1 for starting explosive motor 6 relative to the dotted line in figure is turned round
Square.Parameter t, R, h are for determining that this additionally increases the value of method.
When with reference to Fig. 4 B, parameter t represents that t1 plays beginning extra increase target horse in time starting push-jump explosive motor 6
Reach the time of moment of torsion.Parameter h represents the absolute magnitude of extra increase.Parameter R represents the speed reaching extra increments h.In other words
Saying, parameter t is the shortest, parameter h is the biggest, parameter R is the biggest, and target motor torsional moment is more increased dramatically.
Controller 12, by referring to the corresponding diagram prestored in ROM of the characteristic shown in Fig. 4 A, is stepped on according to acceleration
Plate aperture APO determines parameter t, R, h respectively.As known according to figure, accelerator pedal aperture APO is the biggest, parameter t is set
For the least value, parameter h is set as the biggest value, parameter R is set as the biggest value.Controller 12 is according to according to like this
Parameter t that sets, R, h calculate the target motor torsional moment of motor generator 1, and by defeated by motor generator 1 of inverter 7
Go out moment of torsion to control as target motor torsional moment.Thus, defeated with the motor generator 1 carried out in step S5 described later and step S7
The control going out moment of torsion is compared, it is possible to response starts explosive motor 6 well, it is possible to obtain high booster response.
On the other hand, in the case of being judged as negative of step S1, controller 12 is in step s 2 based on carrying out self-blocking
Whether the input-signal judging automatic speed variator 4 of switch 15 is set to motor pattern.Motor pattern is that driver passes through operation
Gear lever and the driving mode that is pre-selected.In the case of automatic speed variator 4 is set to motor pattern, controller 12 is carried out
The process of step S6.
In the case of automatic speed variator 4 is not set to motor pattern, controller 12 in step s3 based on from
The input signal of disconnect switch 15 judges whether automatic speed variator 4 is set to manual mode.Manual mode is that driver is led to
Cross manual operation to change the driving mode of gear ratio.Manual mode is pre-selected by operation gear lever.Additionally,
Hybrid power drives in electric automobile 20, as the driving mode in addition to motor pattern, manual mode, be set be applied to general
The current economic model sailed.In the case of automatic speed variator 4 is set to manual mode, controller 12 carries out the place of step S6
Reason.
The place of step S6 identical when why carrying out big with the degree of acceleration request under motor pattern, manual mode
Reason, is owing in these modes, more paying attention to the response for operation compared with preventing from impacting.
In the case of automatic speed variator 4 is not set to manual mode in step s3, controller 12 is in step s 4
Judge explosive motor 6 starts whether request derives from the startup request sent by hybrid electric drive system.Here, by base
Startup in the explosive motor 6 of the reason in addition to the acceleration request of driver is all set to derive from system request.Coming
The startup of the explosive motor 6 coming from system request includes that charging of battery etc. is in maintaining hybrid electric drive system
The startup of burn engine 6.
In the case of the judgement of step S4 is affirmative, in the same manner as step S6, controller 12 is in step s 5 based on adding
Speed pedal aperture APO determines parameter t, R, h, based on parameter t, R, h target setting motor torsional moment.Here, step S5 uses
Parameter t, R, h corresponding diagram with in step S6 use corresponding diagram compared with, be set to relative to identical accelerator pedal aperture
APO provides bigger t, less h and less R.This corresponding diagram is also pre-stored in ROM.
Its result, in step s 5 according to parameter t, the target motor torsional moment of the motor generator 1 of R, h calculating and in step
The target motor torsional moment determined in S6 is compared, and the extra beginning increased is delayed, and the extra absolute magnitude increased diminishes, and target motor
The speed of absolute magnitude that moment of torsion reaches additionally to increase is the most slack-off.As result, the increase of the target motor torsional moment of motor generator 1
Rest on slow and little amount, the impact caused by being increased dramatically of motor torsional moment of motor generator 1 thus without generation,
Driver, co-driver will not feel well due to impact yet.
On the other hand, in the case of being judged as negative of step S4, in the same manner as step S6, controller 12 is in step S7
In based on accelerator pedal aperture APO determine parameter t, R, h, based on parameter t, R, h target setting motor torsional moment.Here, in step
Parameter t, the corresponding diagram of R, h that use in S7 are set to the t of degree, the h of middle degree and the R of middle degree in offer.So-called
Middle degree, refers to parameter t, R, h and the corresponding diagram institute used in step s 6 that the corresponding diagram used in step s 5 is provided
Parameter t of offer, the respective intermediate value of R, h.This corresponding diagram is also pre-stored in ROM.Controller 12 is like this in step
S5, S6 and S7 use different corresponding diagram.
The extra of the target motor torsional moment set in the step s 7 increases time started t, extra increments h and reaches volume
Speed R of outer increments is respectively the value set in step s 5 and the intermediate value of the value set in step s 6.Step S7 institute
Perform is the acceleration request of driver, and is the little situation of the degree of acceleration request.In this case, by ginseng
Number uses intermediate value, it is possible to suppress by starting the impact that explosive motor 6 causes to a certain extent, while obtaining certain
The booster response of the degree of kind.After the process of the either step in step S5, S6 and S7, controller 12 terminates routine.
The result of the execution of the engine start control routine of Fig. 2 is described with reference to Fig. 3 A-Fig. 3 E.The figure shows at Fig. 2
Routine in carried out the situation of process of step S6.
When with reference to Fig. 3 A, the moment t1 after accelerator pedal aperture from idling transport condition increases, controller 12
Determine to start explosive motor 6.At this time point, as shown in FIGURE 3 E, the transmission moment of torsion of the first friction engagement element 5 is
Zero.On the other hand, controller 12 makes the hydraulic pressure utilizing hydraulic pressure unit 8 to supply to the second friction engagement element 3 reduce, so that the
The transmission moment of torsion of two friction engagement element 3 reduces.
The result of the process of step S6 of the routine of Fig. 2 is, as shown in Figure 3 D, have passed through time t's from moment t1
Time point, the target motor torsional moment of motor generator 1 starts additionally to increase.Additionally increase with speed R, reaching extra increments
After h, target torque increases in parallel with the dotted line of figure.
After the time t 2, as shown in FIGURE 3 E, controller 12 makes from hydraulic pressure supply unit 9 to the first friction engagement element 5
The hydraulic pressure of supply rises, and makes the first friction engagement element 5 carry out action in sliding mode.Similarly, as shown in Figure 3 D, control
Device 12 makes the hydraulic pressure supplied to the second friction engagement element 3 from hydraulic pressure unit 8 rise, and makes the second friction engagement element 3 slide
Action is carried out under pattern.It addition, as shown in Figure 3 C, controller 12 is after the time t 2 by the control relevant with motor generator 1
Object switch to rotating speed from moment of torsion.It is to say, make the control of target torque based on motor generator 1 terminate, transfer to
The control of rotating speed of target based on motor generator 1.Thus, the change of the motor torsional moment of the period from moment t2 to t3 is rotating speed
The result controlled.
At moment t3, controller makes the supply hydraulic pressure of hydraulic pressure supply unit 8 further up, makes the second friction engagement element
3 tend to engagement state.Synchronization at moment t4, the rotating speed of explosive motor 6 and motor generator 1.Controller 12 makes liquid
The supply hydraulic pressure of pressure feed unit 9 is further up and makes the first friction engagement element 5 for engagement state.Afterwards, utilization becomes
First friction engagement element 5 and the second friction engagement element 3 of engagement state, uses explosive motor 6 and dynamoelectric and power generation simultaneously
The power of machine 1 carries out hybrid power and drives the operating of electric automobile 20.
Send out as it has been described above, this engine start control device starts in the case of the degree of the acceleration request of driver is big
During motivation, the target motor torsional moment of motor generator 1 is started increase timing from start push-jump delay time t contracting
Short.It is to say, perform the extra increase of the target motor torsional moment of motor generator 1 the most in advance.Therefore, it is possible to for adding
The operation of the accelerator pedal needed for speed request and response starts explosive motor 6 well, and utilize the torsion of explosive motor 6
Square makes hybrid power drive electric automobile 20 to accelerate rapidly.
On the other hand, when starting electromotor in the case of the degree of acceleration request is little, big with the degree of acceleration request
Situation compare, the timing starting the target motor torsional moment of motor generator 1 to increase from start push-jump the time t of delay
Extend.Therefore, it is possible to the impact that suppression is increased by the moment of torsion of the motor generator 1 under the less desirable state of driver and causes.
It addition, this engine start control device starts electromotor in the case of the degree of the acceleration request of driver is big
Time, make extra increments h of the target motor torsional moment of motor generator 1 increase.Can be further by increasing extra increments h
Improve the response accelerated.
It addition, this engine start control device starts electromotor in the case of the degree of the acceleration request of driver is big
Time, make speed R reaching extra increments h increase.The response of acceleration can be improved further by making arrival rate R increase.
Additionally, in this embodiment, three parameters t, h, R all change, but are not necessarily required to all become these three
More, by by least one change in parameter t, h, R, it is possible to realize impact when preventing acceleration request little, and obtain with
The effect that booster response when raising acceleration request is big matches.
In this embodiment, the size of acceleration request, as shown in Figure 4 A, root are judged according to accelerator pedal aperture APO
Setup parameter t, h, R is come according to accelerator pedal aperture APO.Therefore, it is possible to make the acceleration of driver be intended to quickly and reliably reflect
On the moment of torsion of motor generator 1.
In this embodiment, when starting explosive motor 6 under motor pattern and manual mode, ask based on acceleration
The corresponding diagram that the situation of asking big is identical comes setup parameter t, h, R.Therefore, under the two pattern and economic model, improve response
Different with the proportion preventing impact, it is possible to carry out the multiple setting relevant with taking sense.
In the above embodiment, about the situation that the degree of the acceleration request of driver is little, enter in step s 4
One step is divided into situation that the degree of acceleration request is little and there is not the situation of acceleration request, about the moment of torsion control of motor generator 1
System, S7 carries out different process in step s 5.However, it is also possible to do not carry out the judgement of step S4 and the process of step S7,
In the case of being judged as negative of step S3, whether there is acceleration request and all carry out the process of step S5.
