26 etc..In controller of vehicle 1, according to the information being detected by these various sensors 21～26, implement idle stop control
System, uphill starting auxiliary control and driving force correction controls.
(2. control content) so-called idle stop controls, and is automatically to make engine 11 according to stopping, the starting of vehicle 10
The control temporarily cease, restarted.The beginning condition that idle stop controls, is for example to detect that brake pedal 16 is trampled,
And speed v substantially 0 etc..On the other hand, the termination condition that idle stop controls, is to detect that brake pedal 16 is not trampled
Or detect that accelerator open degree aps (stampede operation of gas pedal) is setting with first-class.
So-called uphill starting auxiliary controls, and is to suppress uphill starting using the latter in two kinds of functions of hydraulic pressure unit 15
When vehicle downslide control.Uphill starting auxiliary control beginning condition, be for example speed v substantially 0 (vehicle 10 stops
In) and the absolute value of road surface gradient theta exceedes setting θ 0 etc..Thus, when vehicle 10 is temporary transient in upward slope to a certain degree, descending
During stopping, in one section of period after release brake pedal 16, brake hydraulic p automatically continuingly acts on wheel drag
14, thus suppressing the downslide of vehicle 10.
The correction of so-called driving force controls, and is the car exporting wheel 13 side after correction vehicle 10 ground zero from variable-speed motor 12
Wheel drive force, improves riding stability during vehicle start and the control driving sense.In this control, such as according to uphill starting
The deviation of engine drive power when having the deviation of efficacious prescriptions, engine 11 to start of the brake force that auxiliary controls, corresponding driver
Starting requires and acceleration request and variation of target drive force of setting etc., to adjust the interlocking confining force in variable-speed motor 12.
The driving force correction of present embodiment controls, real when controlling vehicle 10 starting when being recovered from idle stop
Apply.In addition, the size of interlocking confining force, can be controlled by the fastening force degree of change friction engagement element, become to specific
The method of more tightness is arbitrary.Below, describe the content that driving force correction controls in detail.
(3. controller of vehicle) is provided with calculating section 2 and variable-speed motor control unit 7 on controller of vehicle 1.These are each
Key element, both can be realized by circuit (hardware), or was alternatively the software of programming, or also can make the part in these functions
For hardware, other parts are software.
The purposes of calculating section 2 is to calculate the various parameters relevant with driving force correction control.Here as shown in fig. 1, if
It is equipped with engine drive power calculating section 3, brake force calculating section 4, target drive force calculating section 5 and interlocking confining force calculating section 6.
The purposes of engine drive power calculating section 3 (engine drive power calculates component) is to calculate produced by engine 11
Engine drive power a.Here, engine drive power a is calculated according to engine speed ne and accelerator open degree aps.In addition, in vehicle
In the case that 10 have engine ecu, may be alternatively configured the control knot reading in the engine drive power a being calculated by engine ecu
Structure.The information of the engine drive power a obtaining here is passed to interlocking confining force calculating section 6.
The purposes of brake force calculating section 4 (brake force calculates component) is to calculate brake force b resulting from wheel drag 14.
Here, for example examined according to the brake hydraulic p that detected by brake hydraulic sensor 23 and by brake liquid temperature sensor 26
Brake liquid temperature t measured and calculate brake force b.Therefore, for brake force b, not only comprise the brake force of uphill starting auxiliary,
Also comprise to trample occurred brake force by brake pedal 16.The information of brake force b calculating here is passed to interlocking
Confining force calculating section 6.
For brake force b calculating herein, reflect the state of brake liquid temperature t.For example, brake liquid temperature t is high
Warm brake force b is less or the computing of variable gradient that enter to exercise brake force b more increase.On the contrary, brake liquid temperature t is low
Warm brake force b is bigger or the computing of variable gradient that enter to exercise brake force b more reduction.So, the information of brake liquid temperature t
For holding the characteristic related to the easness that disappears of brake force.
The purposes of target drive force calculating section 5 (target drive force calculates component) is the drive calculating as required for vehicle 10
Target drive force c of the desired value of power.Target drive force c is the driving force travelling for making vehicle 10 smoothly start to walk, according to
Engine speed ne, accelerator open degree aps and road surface gradient theta and calculate.The value of target drive force c is calculated as such as road surface slope
Degree θ bigger (being more inclined upwardly) and bigger, road surface gradient theta less (more downward-sloping) and less.Here the target drives calculating
The information of power c is passed to interlocking confining force calculating section 6.
The purposes of interlocking confining force calculating section 6 (interlocked control component) is to calculate the interlocking confining force d of variable-speed motor 2 generation.
Interlocking confining force d calculates according to engine drive power a and the difference of brake force b.Here, the variable gradient to interlocking confining force d
Operation method in the case of being controlled and the operation method in the case that size is controlled illustrate.
In the case that the variable gradient to interlocking confining force d is controlled, during vehicle 10 starting, interlocking confining force d is set
Surely become initial holding force d0 set in advance, meanwhile, breakaway speed δ d (the open speed of interlocking of interlocking confining force d thereafter
Degree) calculated according to engine drive power a and the difference of brake force b.For example, as the difference (a- of engine drive power a and brake force b
When b) being less than target drive force c, the breakaway speed δ d of the time per unit of interlocking confining force d is just maked corrections to increase direction.
This correction is equivalent to the operation of the minimizing speed improving interlocking confining force d.On the other hand, when engine drive power a and brake force b

The operation of the minimizing speed of interlocking confining force d.
In addition, to control breakaway speed δ d also dependent on brake liquid temperature t.For example, brake liquid temperature t low temperature, leaves
Put speed δ d more to be maked corrections to increase direction, brake liquid temperature t high temperature, breakaway speed δ d more obtains to minimizing direction
Correction.In addition, brake force b being calculated by brake force calculating section 4 for present embodiment, reflect brake liquid temperature t
State.
Interlocking confining force d such as root in the case that the size to interlocking confining force d is controlled, during vehicle 10 starting
Calculate according to following formula 1.In the case of being somebody's turn to do, when target drive force c mono- timing, the corresponding engine drive power a of interlocking confining force d and braking
The difference of power b and change.That is, interlocking confining force d calculates according to engine drive power a and the difference of brake force b.If in addition, having in mind
In the relation with target drive force c, then interlock confining force d after the difference according to engine drive power a and brake force b calculates,
Become the value after making corrections according to target drive force c.The information of the interlocking confining force d calculating here is passed to variable-speed motor control
Portion 7.
D=a-b-c ... (formula 1)
The purposes of variable-speed motor control unit 7 (interlocked control component) is, according to the interlocking being calculated by interlocking confining force calculating section 6
Confining force d and its breakaway speed δ d etc. and the fastening force of the friction engagement element within variable-speed motor 12 is controlled.That is, become
Fast machine control unit 7 is controlled to the fastening state keeping the friction engagement element to variable-speed motor 12 and applies brake force to wheel 13.
Here, corresponding to two kinds of operation methods about the confining force d that interlocks it is contemplated that implementing two kinds of controls.
First method is: improve the fastening pressure of friction engagement element, until interlocking confining force d during vehicle 10 starting
Reach initial holding force d0, after interlocking confining force d reaches initial holding force d0, calculate according to by interlocking confining force calculating section 6
And the breakaway speed δ d after being maked corrections reduces the fastening pressure of friction engagement element.In the case of being somebody's turn to do, such as when target drive force c
During more than value (a-b), postpone fastening speed and the breakaway speed of interlocking, when target drive force c is less than value (a-b), accelerate to rub
Wipe fastening speed and the breakaway speed of engagement element.
The state that c ＞ (a-b) sets up, is that the driving force after engine drive power a deducts brake force b is driven with respect to target
When power c is slightly smaller.In this case, the variable-speed motor 12 interlocking confining force d of that should be absorbed, reduce friction engagement element
Fastening speed, breakaway speed, extend the action time of interlocking confining force d.On the other hand, the state that c ＜ (a-b) sets up, be from
Engine drive power a deduct brake force b after driving force with respect to target drive force c be big when.In this case, should shorten
The action time of interlocking confining force d, improve fastening speed, the breakaway speed of friction engagement element.
In addition, in the occasion in view of brake liquid temperature t, brake liquid temperature t high temperature, the viscosity of brake fluid is got over
Decline, the action time of brake force b gets over and shortens.Therefore, in this occasion, the action time of interlocking confining force d should be extended and prolong
The releasing time of interlocking late, thus reduce the fastening speed of friction engagement element, breakaway speed.On the contrary, if brake liquid temperature t is
Low temperature, should shorten the action time of interlocking confining force d, thus improving the fastening speed of friction engagement element, breakaway speed.
Second method is: the fastening force of friction engagement element is controlled into, is produced by variable-speed motor 12 and keep with by interlocking
The brake force of the interlocking confining force d formed objects that power calculating section 6 calculates.In this case, actual interlocking confining force d is with sending out
Motivation driving force a increases and becomes big, reduces with engine drive power a and diminishes.On the other hand, with respect to brake force b and mesh
Mark the change of driving force c and take contrary movement, for example, brake force b is got over and increased, and more reduces the interlocking confining force d of reality,
Brake force b is got over and is reduced, and more increases actual interlocking confining force d.
Using the control of first method, can be considered the control of the time increase and decrease making interlocking confining force d be acted on.The opposing party
Face, using the control of second method, can be considered the control of the size of increase and decrease interlocking confining force d.The no matter situation of which kind of method
Under, the size of the wheel driving force exporting to wheel 13 side from variable-speed motor 12 is suitably changed, and improves traveling during vehicle start
Stability and driving sense.
(4. flow chart) Fig. 2 is the flow chart illustrating the order that the driving force correction implemented in controller of vehicle 1 controls.
Here, the flow process during control of time that illustration enforcement increase and decrease interlocking confining force d is acted on.
In step a10, in controller of vehicle 1, judge whether the beginning condition that idle stop controls is set up.Here,
In the case that the beginning condition that idle stop controls is set up, enter step a20, in the case of invalid, terminate its computing
The flow process in cycle.
In addition, in step a20, judging whether the beginning condition that uphill starting auxiliary controls is set up.For example, judge road surface
Whether the absolute value of gradient θ exceedes setting θ 0.Here, if the beginning condition that uphill starting auxiliary controls is set up, enter step
Rapid a30, starts uphill starting auxiliary and controls.Should in the case of, the braking that keeps the tread-on quantity of corresponding brake pedal 16 and produce
Device hydraulic pressure p, enters step a40.On the other hand, if the beginning condition that uphill starting auxiliary controls is false, enter at that
Step a40.
In step a40, implement idle stop and control.In this step, the fuel supply feeding to engine 11 is cut-off, sends out
Motivation 11 is out of service.In step a50 then, judge whether the termination condition that idle stop controls is set up.For example, if inspection
Measure the not released of brake pedal 16, then the termination condition that idle stop controls is set up, and enters step a60.On the other hand,
In the case of termination condition is invalid, then controls and return to step a40, continue idle stop and control.
In step a60, start again at the fuel supply to engine 11, engine 11 is again started up automatically.Then
Step a70 in, target drive force calculating section 5 calculates target drive force c according to engine speed ne and road surface gradient theta.Separately
Outward, in then its step a80, interlocking confining force d is set to initial holding force d0 set in advance, simultaneously initial with this
The corresponding control signal of confining force d0 exports variable-speed motor 12 from controller of vehicle 1.Thus, incite somebody to action in the inside of variable-speed motor 12
To initial holding force d0 fastening force as desired value, the fastening pressure of the engagement element that rubs rises, and interlocking confining force d gradually increases
Plus.
Further, in step a90, judge whether engine speed ne exceedes the startup rotating speed ne0 of regulation, here,
In the case of the establishment of ne ＞ ne0, then enter step a100.On the other hand, in the invalid situation of decision condition of step a90
Under, then control and return to step a60, continue the start-up operation of engine 11.
In step a100, judge whether the variable quantity δ ne of the time per unit of engine speed ne is steady less than regulation
Determine Grad δ ne0, here, in the case that δ ne ＜ δ ne0 sets up, then enter step a110.On the other hand, in step
In the case of the decision condition of a100 is invalid, then controls and return to step a60, continue the start-up operation of engine 11.
In step a110, interlocking confining force d is controlled so as to, and interlocking confining force d reduces the open speed of regulation set in advance
Degree δ d0.In this step, control signal corresponding with regulation breakaway speed δ d0 exports variable-speed motor from controller of vehicle 1
12.Thus, the fastening pressure of friction engagement element declines, and interlocking confining force d is gradually reduced.
In step a120, target drive force c is calculated by target drive force calculating section 5.Here, according to engine speed
Ne, accelerator open degree aps and road surface gradient theta and calculate target drive force c, correction target drive force is intended to according to the starting of driver
c.In step a130 then, calculated according to engine speed ne and accelerator open degree aps by engine drive power calculating section 3 and send out
Motivation driving force a.In addition, in step a140, brake force b is calculated according to brake hydraulic p by brake force calculating section 4.
In step a150, judge whether target drive force c is bigger with the difference (a-b) of brake force b than engine drive power a.
In the case that this decision condition is set up, it is judged as that actual transfer arrives driving force ratio target drive force c of wheel 13 side greatly (i.e.,
It is the sufficiently large state of brake force b) and enter step a160, the breakaway speed δ d of interlocking confining force d is mended to increasing direction
Just.On the other hand, in the case of the decision condition of step a150 is invalid, it is judged as the driving force ratio target drive force of reality
C little (that is, brake force b is not enough) simultaneously enters step a170, and the breakaway speed δ d of interlocking confining force d is maked corrections to reducing direction.
In these steps a160, a170, fill from wagon control with the corresponding control signal of breakaway speed δ d being maked corrections
Put 1 output to variable-speed motor 12.Thus, the action time of interlocking confining force d is properly adjusted, defeated to wheel 13 side from variable-speed motor 12
The size of the wheel driving force going out suitably is changed.In addition, in step a180, judge interlocking confining force d size be whether 0 with
Under.Here, in the case of being d 0, terminate this flow process, driving force correction control terminates.On the other hand, in the feelings being d ＞ 0
Under condition, control and return to step a110, control breakaway speed δ d until interlocking confining force d is 0.
In addition, above-mentioned flow chart is the diagram that the action time to interlocking confining force d is controlled.In this regard, controlling
In the case of interlocking confining force d size, as long as change step a80 and step a150～a170.For example, if rubbing to reducing
Interlocking confining force d during the fastening pressure of engagement element is controlled, then it is contemplated that such control structure: in step a150
In, interlocking confining force d is calculated according to formula 1, corresponding control signal is exported variable-speed motor 12 from controller of vehicle 1.
In this case, step a160, a170 can be omitted.Equally, may be alternatively configured such control structure: if to making friction
Interlocking confining force d when the fastening pressure of engagement element increases is controlled, then calculate interlocking confining force d in step a80, will be with
Its corresponding control signal exports variable-speed motor 12 from controller of vehicle 1.
In addition, in the case of making brake liquid temperature t be reflected in the control of interlocking confining force d, in above-mentioned flow chart
Before step a170, also can increase according to brake liquid temperature t to increasing direction or reduce direction to interlocking the opening of confining force d
The step that speed δ d is maked corrections.If additionally, the interlocking confining force d when fastening pressure making friction engagement element is increased enters
Row controls, also can in step a80 according to brake liquid temperature t the initial holding force d0 that makes corrections, or, to increasing direction or minimizing
Direction makes corrections to the fastening speed of interlocking confining force d.
(5. act on) Fig. 3 (a)～(g) represent for illustrate vehicle 10 when stopping to controller of vehicle 1 during starting
The time diagram of control action.Moment t1 be trample the vehicle 10 in traveling brake pedal 16 and stop after moment, the moment
T2 is the moment that the beginning condition that idle stop controls is set up.In addition, the interlocking confining force d shown in Fig. 3 (e) represents variable-speed motor 12
In confining force variation, described variable-speed motor 12 has the speed change oil pump being operated using the driving force of engine 11.
When idle stop controls beginning, as shown in Fig. 3 (b), with out of service, the engine drive power of engine 11
A reduces.Now, it is switched to, from forward travel state, shape of interlocking shown in the state such as Fig. 3 (d) of the clutch being built in variable-speed motor 12
State.
When this vehicle 10 stops, in the case that the absolute value of road surface gradient theta exceedes fixed value θ 0, start ramp and rise
Step auxiliary controls.Thus, step on power corresponding brake hydraulic p with brake and be held in wheel drag 14.Then, in the moment
During t3 release brake pedal 16, as shown in Fig. 3 (c) chain lines, brake is stepped on power and is reduced.But, due to indicated by the solid line
Brake force b after release brake pedal 16 period also slightly a moment later be maintained, thus suppressing the downslide of vehicle 10.Separately
Outward, if the termination condition that idle stop controls is set up because of release brake pedal 16, start the start-up operation of engine 11,
Start simultaneously at driving force correction to control.
Uphill starting auxiliary controls the moment t4 after t3 have passed through the stipulated time from the moment to terminate, then under brake force b
Fall.Here, shown in solid such as in Fig. 3 (c), if brake liquid temperature t is the minimizing speed of high temperature, brake force b, engine
The difference (a-b) of driving force a and brake force b is just rapid to be risen, i.e. poor (a-b) relative target driving force c and relatively easy change
Greatly.
Therefore, the breakaway speed δ d of interlocking confining force d is easily maked corrections to minimizing direction, and as solid line in Fig. 3 (e)
Shown, the open delay of friction engagement element, thus extend the action time of interlocking confining force d.That is, the disappearance portion of brake force b
Divide to be supplemented by interlocking confining force d.Therefore, as wheel shown in solid in Fig. 3 (f), transmitting to gear 13 side from variable-speed motor 12
Driving force smoothly rises.In addition, for the acceleration of car body, drastically will not change as shown in solid in Fig. 3 (g), energy
Enough suppress the sense that flies out of vehicle 10.
On the other hand, as shown in dotted line in Fig. 3 (c), the minimizing speed being low temperature and brake force b when brake liquid temperature t is relatively
When slow, engine drive power a is just slow with the difference (a-b) of brake force b to be risen, i.e. poor (a-b) is with respect to target drive force c
Relatively easy diminish.Therefore, the breakaway speed δ d of interlocking confining force d is readily obtained correction to increasing direction, and such as Fig. 3 (e) is empty
Shown in line, promote the opening of friction engagement element and shorten the action time of interlocking confining force d.That is, it is difficult to decline in brake force b
In the state of, interlocking confining force d is just rapid to be reduced, and the driving force to the transmission of wheel 13 side will not too become big, suppresses hook sense.
Situation shown in solid in the acceleration of wheel driving force and car body such as Fig. 3 (f), (g), with the minimizing speed of brake force b
Under change substantially in the same manner.
Even if in addition, the minimizing speed of brake force b be faster in the case of, when idle stop control just terminate after trample
During gas pedal, the starting of this driver requires to be reflected in target drive force c, the difference of engine drive power a and brake force b
(a-b) relatively easy with respect to target drive force c diminish.
Therefore, the breakaway speed δ d of interlocking confining force d is readily obtained correction to increasing direction, such as Fig. 3 (e) chain lines
Shown, interlocking confining force d action time than interlocking confining force d indicated by the solid line curve map shortening.That is, from variable-speed motor 12
Driving force to wheel 13 transmission increased in the more early moment.Therefore, as shown in Fig. 3 (f), (g) chain lines, wheel driving force and
The acceleration of car body looks like according to the starting of driver and increases rapidly, and the acceleration reactivity of vehicle 10 improves.
(6. effect) (1) so, using above-mentioned controller of vehicle 1, due to according to engine drive power a and brake force
The difference (a-b) of b and control interlocking confining force d, therefore, even if in the case that the size of brake force b and action time are change,
Also the driving force being delivered to wheel 13 side can be suppressed drastically to change.Therefore, it is possible to improve the riding stability of vehicle.
(2) in addition, in above-mentioned controller of vehicle 1, not only according to the difference (a- of engine drive power a and brake force b
B), and according to target drive force c control interlocking confining force d.Thus, can be anticipated according to the starting of road surface gradient theta and driver
Think and control the movement of vehicle 10, riding stability when vehicle advances can be improved and accelerate reactivity.
(3) especially, in above-mentioned controller of vehicle 1, due to the difference (a- according to engine drive power a and brake force b
B) to control the breakaway speed δ d of interlocking confining force d with the magnitude relationship of target drive force c, to drive therefore, it is possible to suitably process
The starting meaning of the person of sailing and the interlocking confining force d (effect implementing time and interlocking confining force d that for example, driving force correction controls
Time, size of interlocking confining force d etc.), it is possible to increase riding stability when vehicle advances and acceleration reactivity.
(4) additionally, in above-mentioned controller of vehicle 1, target drive force c is calculated according to road surface gradient theta.For example, exist
When the gradient on abrupt slope is advanced, target drive force c calculate value than flat road advance when big, the confining force d that interlocks quickly reduces,
Therefore wheel driving force rises in advance.Therefore, downslide when vehicle advances and the inhibition flying out can be improved.
(5) in addition, in above-mentioned controller of vehicle 1, keeping to controlling interlocking when recovering from idle stop
Power d is controlled using driving force correction and controls.Thus, unstable rotation institute after suitably suppressing to restart because of engine 11
The unstable variation of the driving force causing is such that it is able to improve the riding stability of vehicle.
(6) in addition, in above-mentioned controller of vehicle 1, being controlled using idle stop at the same time and uphill starting auxiliary
Under the situation controlling, also maked corrections using driving force and control thus controlling interlocking confining force d.Thus, even if in engine drive power a
Rise time and brake force b fall time inconsistent in the case of, also can suitably apply the confining force d that interlocks, improve vehicle
Riding stability.
(7) in addition, in above-mentioned controller of vehicle 1, controlling connection with brake force b calculating according to brake liquid temperature t
The action time of lock confining force d.For example, if brake liquid temperature t is relatively low, it is braked the change of the increase of power b or brake force b
The computing that gradient reduces, the confining force d that is therefore controlled so as to interlock relatively diminish or the confining force d that interlocks breakaway speed δ d to increasing
General orientation is maked corrections.On the other hand, if brake liquid temperature t is high temperature, power b that is braked reduces or the change of brake force b is terraced
The computing that degree increases, the confining force d that is therefore controlled so as to interlock relatively becomes the breakaway speed δ d of big or interlocking confining force d to minimizing
Direction is maked corrections.
So, using the control of the interlocking confining force d according to brake liquid temperature t, the viscosity of brake fluid can suitably be evaluated, can
Accurately hold the characteristic (for example, from the decrease speed of moment brake force b of release brake pedal 16) of brake force b, can
Reflected into the control of interlocking confining force d.Improve vehicle therefore, it is possible to the not size according to brake force b (effective situation)
Riding stability.
(8) in addition, brake liquid temperature t high temperature, the viscosity more decline of brake fluid, brake force b disappears in advance.On the contrary,
In above-mentioned controller of vehicle 1, due to controlling interlocking confining force d so that the time point of opening is postponed, therefore available interlocking keeps
Power d supplements the insufficient section of brake force b.Therefore, engine drive power a will not be applied excessively or insufficiently in vehicle start
Brake force, it is possible to increase the riding stability of vehicle.
(9) in addition, in above-mentioned controller of vehicle 1, in such as brake liquid temperature t, high temperature is got over to minimizing direction
To interlocking confining force d breakaway speed δ d make corrections in the case of, extend interlocking confining force d the applying of essence during.
Thus, even if in the case of disappearing within the brake force b short time, also ensuring that during vehicle start with respect to engine drive power a
Brake force, thus improving the riding stability of vehicle.
(7. variation) in the above-described embodiment, exemplified with when from idle stop control recovered when vehicle 10
Implement driving force correction during starting to control, but implement the time point not limited to this that driving force correction controls.For example, it is not limited to from idle
When speed stopping control being recovered, also can implement driving force correction when vehicle 10 is started to walk all the time and control, or slow in vehicle 10
When speed travels while travelling (such as slowly) and usual implement driving force correction control when travelling.Which kind of, either in the case of, all obtain
Obtain and the effect of above-mentioned embodiment identical and effect.
In addition, in the above-described embodiment, right as controlling exemplified with the confining force d and its breakaway speed δ d that will interlock
As also or replacing and using the fastening speed of interlocking confining force d as control object, incite somebody to action on this control formation base
As control object during the applying of interlocking confining force d.For example it is contemplated that: when target drive force c be more than value (a-b) when, will join
The solid speed of locking is maked corrections to increasing direction, when target drive force c be value (a-b) below when, speed will be fastened to minimizing side
To being maked corrections.In the former case, interlocking confining force d is rapid becomes big, and result interlocking confining force d is reinforced.On the other hand,
In the latter case, because interlocking confining force d slowly increases, therefore result interlocking confining force d weakens.
In addition it is contemplated that: when target drive force c is more than value (a-b), extend during the applying of interlocking confining force d, when
Target drive force c be value (a-b) below when, by interlocking confining force d applying during shorten.In the former case, with regard to long when
Between effect interlocking confining force d, that is, interlocking confining force d be reinforced.On the contrary, in the latter case, interlocking confining force d weakens.As
This, by complementally processing the power of brake force b and the power of interlocking confining force d, thus obtain and above-mentioned embodiment phase
Same effect and effect.
In addition in the above-described embodiment, exemplified with the difference (a-b) according to engine drive power a and brake force b and mesh
Mark the magnitude relationship of driving force c and control interlocking confining force d, but specific control method is not limited to this.For example, also dependent on
Above-mentioned formula 1 computing interlocking confining force d, the Interlock Status of variable-speed motor 12 is controlled into the holding making reality be occurred by variable-speed motor 12
Power with interlocking confining force d operation values consistent (or close).
Or, control interlocking confining force d also dependent on brake liquid temperature t being detected by brake liquid temperature sensor 26.
In this case it is contemplated that: brake liquid temperature t low temperature, more reduce interlocking confining force d, or by breakaway speed δ d to increase
Direction is maked corrections.Contrary it is contemplated that: brake liquid temperature t high temperature, more increase interlocking confining force d, or by breakaway speed δ
D is maked corrections to reducing direction.
That is, being controlled into according to the brake characteristic changing with brake liquid temperature t: easily disappear in brake force
Under state, it is supplemented with interlocking confining force d, do not make interlocking confining force d superfluous in the state of brake force is difficult to disappear.
For example, become high temperature with brake liquid temperature t, make the time that releasing is interlocked (interlocking confining force d start time and the knot of opening
Time of Shu Kaifang etc.) postpone.In this control, also obtain and the effect of above-mentioned embodiment identical and effect.
In addition, in the above-described embodiment, calculate brake force b exemplified with brake liquid temperature t, control interlocking to protect accordingly
Holding force d, but brake liquid temperature t also can be replaced using external air temperature and car indoor temperature etc..If at least with confirm as with
The related environment temperature of brake force b, just obtains and above-mentioned embodiment identical effect and effect.
