Embodiment
Hereinafter, embodiments of the present invention are illustrated according to Fig. 1~Fig. 8.
As shown in figure 1, the four-wheel drive vehicle of present embodiment has the hair that Vehicular body front is equipped in a manner of horizontal
Motivation E, the speed changer T being connected with engine E and the differential gear D being integrally provided with speed changer T, from differential gear D courts
The drive axle Sf extended to the left and right is connected with the left and right front-wheel Wf as main drive wheel.In addition, from differential gear D towards rear
The power transmission shaft Sp of extension rear end is connected with left and right clutch C, from left and right clutch C towards the rear drive shaft Sr of left and right and conduct
The left and right trailing wheel Wr connections of secondary driving wheel.
Therefore, increased by the moment of torsion for increasing left and right clutch C engaging force and distributing to left and right trailing wheel Wr, and divided
Dispensing or so front-wheel Wf moment of torsion reduces.If set as caused by engine E, total torque is 100%, trailing wheel distribution moment of torsion quilt
Control is in the range of such as 70%~30%, and correspondingly, front-wheel distribution moment of torsion is carried out in the range of 30%~70%
Change.
In addition, in the case where left and right clutch C engaging force is equal, off hind wheel Wr distributes equal moment of torsion to the left, but
It is that any of 0%~100% scope of moment of torsion can be distributed with trailing wheel by making left and right clutch C engaging force different
Ratio distributes moment of torsion to left and right trailing wheel Wr.
Fig. 2 is the figure for showing to be arranged at the moment of torsion display device on the liquid crystal panel of instrument board.The moment of torsion display device has
There are 4 bar-shaped moment of torsion display unit If, Ir corresponding with left and right front-wheel Wf and left and right trailing wheel Wr respectively, shown using moment of torsion single
First If, the Ir height for lighting part represents the size of the moment of torsion of the wheel.Each moment of torsion display unit If, Ir are divided into series connection
5 section S of ground configuration, each section of S is made up of 10 subsegment s, therefore, it is possible to carry out moment of torsion sendout by amounting to 50 subsegment s
It is substantially continuous display of zero (the full section S extinguishings) to 51 stages of moment of torsion sendout maximum (full section S is lighted).
As shown in figure 3, form the electronic control unit of control mode display unit If, Ir the moment of torsion display device lighted
There is U series to determine processing unit M1, Exception handling portion M2 and display processing portion M3.Series determines that processing unit M1 has torque ratio
Example calculating part m1, front side series determining section m2 and rear side series determining section m3, Exception handling portion M2 have processing unit outside front side
M4 and rear side Exception handling portion m5, display processing portion M3 have front side display speed limiting unit m6 and rear side display speed limiting unit
m7。
Series determines that processing unit M1 moment of torsion ratio calculating part m1 is transfused to left and right front-wheel Wf and a left side as caused by engine E
The basic distribution ratio of off hind wheel Wr total torque and trailing wheel distribution moment of torsion, display processing portion M3 front side display speed limitation
Portion m6 is connected with left and right front-wheel Wf moment of torsion display unit If, display processing portion M3 rear side display speed limiting unit m7 and left and right
Trailing wheel Wr moment of torsion display unit Ir connections.
Next, determine that processing unit M1 effect illustrates to series.
Distribute in moment of torsion in trailing wheel, preset according to front-wheel Wf and trailing wheel Wr car body weight distribution (dead load)
Basic distribution ratio (for example, 40%), therefore, the 60% of total torque is assigned to left and right substantially as caused by engine E
Front-wheel Wf, the 40% of total torque is assigned to left and right trailing wheel Wr.Also, in the feelings of rotating speed of the front-wheel Wf rotating speed more than trailing wheel Wr
Under condition, by make basic distribution ratio from 40% increase and increase to trailing wheel Wr distribution moment of torsion sendout so that front-wheel Wf and
Trailing wheel Wr speed discrepancy converges to zero.On the contrary, in the case of rotating speed of the trailing wheel Wr rotating speed more than front-wheel Wf, by making base
This distribution ratio reduces from 40% and increases the moment of torsion sendout to front-wheel Wf distribution, so that front-wheel Wf and trailing wheel Wr speed discrepancy
Converge to zero.
Moment of torsion ratio calculating part m1 comes by using the maximum of front-wheel distribution moment of torsion divided by the moment of torsion that can distribute to front-wheel Wf
Calculate front side ratio.Although left and right front-wheel Wf is calculated respectively front side ratio, due to left and right front-wheel Wf be allocated it is equal
Moment of torsion, therefore, for left and right front-wheel Wf, front side ratio turns into identical value.In addition, moment of torsion ratio calculating part m1 is by using trailing wheel
Distribution moment of torsion divided by can distribute to trailing wheel Wr moment of torsion maximum come calculate rear side ratio.Although left and right trailing wheel Wr is counted respectively
Rear side ratio is calculated, still, due to that left and right trailing wheel Wr is allocated different moments of torsion be present, therefore, for left and right trailing wheel Wr,
Rear side ratio not necessarily becomes identical value.
In order to control lighting for left and right front-wheel Wf moment of torsion display unit If, front side series determining section m2 passes through at filtering
Each front-wheel distribution moment of torsion after reason determines moment of torsion display unit If's compared with the peak torque that can distribute to each front-wheel Wf
Light level (processing of the 1st series).Specifically, when each front-wheel distributes moment of torsion as that can distribute to each front-wheel Wf peak torque
0% when, light series and be set as the 0th grade and extinguish the section S of whole, when front-wheel distribution moment of torsion be more than 0% and 20% with
When lower, light series and be set as the 1st grade and light a section S, when front-wheel distribution moment of torsion is more than 20% and when below 40%,
Light series to be set as the 2nd grade and light 2 section S, when front-wheel distribution moment of torsion is more than 40% and when below 60%, light level
Number is set as 3rd level and lights 3 section S, when front-wheel distribution moment of torsion is more than 60% and when below 80%, lights series and is set
4 section S are lighted for the 4th grade, when front-wheel distribution moment of torsion is more than 80%, light series be set as the 5th grade and by 5 section S
Light.
As shown in figure 4, front side series determining section m2 also has the counter counted to the duration for respectively lighting level,
What when the gate time of counter continue for the defined time, determination was final lights level (processing of the 2nd series).
More than, series is lighted to the left and right front-wheel Wf moment of torsion display unit If that is realized by front side series determining section m2
The determination of amount is illustrated, and is lighted by the rear side series determining section m3 left and right trailing wheel Wr realized moment of torsion display unit Ir
The determination of level is similarly carried out.
Next, the effect to display processing portion M3 illustrates.
By series lighting of determining that processing unit M1 determines, level is stepped in units of section S to be changed, therefore, such as
This lights level and carrys out lighting for control mode display unit If, Ir the direct use of fruit, then the 10 subsegment s mono- included in a section S
It is lit or extinguishes together, so as to there is the worry that can not accurately show actual change in torque.However, according to this implementation
Mode, as shown in figure 5, front side display speed limiting unit m6 the stair-stepping change respectively lighting level by being smoothed
And it is set to smoothly carry out change.So that 50 subsegment s are continuously lighted or extinguished one by one, so as to accurately
Show actual change in torque.
If if in addition, enter at the same rate when being smoothed the stair-stepping change respectively lighting level
Row smoothing processing, then when the series of change is more, convergence time can be elongated, and actual moment of torsion can not accurately be shown by existing
The worry of change.However, according to present embodiment, so that smoothing processing and the series of change independently press regular hour T1
The mode that (reference picture 5) terminates, i.e. by change series it is more when accelerate subsegment s and light/extinguish speed (diminution is lighted/and put out
Go out time interval), change series it is few when slow down the subsegment s side for lighting/extinguishing speed (increase light/fall time interval)
Formula, to prevent convergence time from becoming long.For example, Fig. 5 shows the 5th grade → the 0th grade of 5 phase changes and the 2nd grade → the 0th
The situation that two phase changes of level are completed in identical time T1.
Next, the effect to Exception handling portion M2 illustrates.
As shown in fig. 6, the 0th grade is judged to the command value that moment of torsion is distributed according to front-wheel and the 1st grade of threshold value sets hysteresis,
When the command value of front-wheel distribution moment of torsion reduces and when being less than the 1st torque threshold LO, then the 0th grade is turned to from the 1st grade of change, when front-wheel divides
When command value with moment of torsion exceeds more than the 1st torque threshold LO the 2nd torque threshold HI, then the 1st grade is turned to from the 0th grade of change.Its
Although as a result, causing driver to step on the throttle pedal, but occur to show as the front-wheel Wf of main drive wheel moment of torsion
Unit If shows the 0th grade, the situation of whole section S extinguishings, there is a possibility that to bring difference to feel to driver.
Therefore, in " the 1st Exception handling " of present embodiment, as shown in fig. 7, even if input display level becomes from the 1st grade
Into the 0th grade, when the accelerator pedal is operated, front side Exception handling portion m4 and rear side Exception handling portion m5 also protect output display level
Hold at the 1st grade, also, at the time of driver unclamps gas pedal, when releasing the rolling counters forward defined time, perform
Output display level is set to become the difference sense of the 1st Exception handling, thus elimination driver that turn to the 0th grade from the 1st grade.
In addition, in the case of operating air-conditioning device and right in order to recover from idle stop state when stopping
In the case that engine E carries out Kick-start, due to not calculating total torque correctly, therefore following possibility be present：To the greatest extent
Pipe driver does not step on the throttle pedal, but display level or moment reach the 2nd grade or 3rd level, and peculiar sense is brought to driver.
Therefore, in " the 2nd Exception handling " of present embodiment, gas pedal is not stepped on to defined amount in driver
More than in the case of, front side Exception handling portion m4 and rear side Exception handling portion m5 are performed the ceiling restriction of output display level the
1 grade of the 2nd Exception handling, thus eliminate the difference sense of driver.
In addition, during Reduced Speed Now the speed untill to 60km/h or so, according to being carried out only with starting
The slow deceleration of brake still carries out the abrupt deceleration using service brake, and front-wheel Wf and trailing wheel Wr car body weight are distributed and sent out
Changing, therefore, front-wheel distribution moment of torsion and trailing wheel distribution moment of torsion become unstable, so in the presence of following possibility：Front-wheel Wf's
Moment of torsion display unit If display level becomes the 0th grade or becomes the 1st grade and cause unstable, and peculiar sense is brought to driver.
Therefore, in " the 3rd Exception handling " of present embodiment, front side Exception handling portion m4 and rear side Exception handling portion m5
Front-wheel Wf moment of torsion display unit If display level is forcibly set as the 0th grade, thus felt to eliminate the difference of driver.
If be described in detail to the processing,
Pulverised condition 1：Gear is parking gear or neutral；
Pulverised condition 2：Gas pedal is disconnected and brake pedal is connected；
Pulverised condition 3：Gas pedal is disconnected and deceleration regime continues the defined time, or the state that brake pedal is connected is held
Time as defined in continuous.
When any condition in these three conditions is set up, forcibly by front-wheel Wf moment of torsion display unit If display
Level is set as the 0th grade (extinguishing full section S).Also, when following pulverised condition subsequents are set up, above-mentioned pulverised condition 3 is released from,
So as to which enforceable 0th grade of setting is released from.
Pulverised condition subsequent：Speed is reduced to below threshold value, or the state that gas pedal is connected continues the defined time.
Fig. 8 is to show that front-wheel Wf moment of torsion display unit If display level is forcibly set as to the 0th grade of the 3rd exception
The time diagram of one of processing.In moment t1, gear is that P is kept off or N gears, pulverised condition 1 are set up, and in moment t2, pulverised condition 1 becomes
Into invalid, enforceable 0th grade of setting is released from.In moment t3, throttle disconnects and brake engagement, pulverised condition 2 into
Vertical, in moment t4, throttle disconnects, and the state of deceleration continues during time T2, and pulverised condition 3 is set up, thus, front-wheel Wf's
It is set as the 0th grade to moment of torsion display unit If being forced property of display level.Then, in moment t5, state that throttle is connected when
Between continue during T3, thus, pulverised condition 3 becomes invalid, and enforceable 0th grade of setting is released from.
In addition, in moment t6, throttle disconnects, and the state of deceleration continues during time T4, and pulverised condition 3 is set up, by
This, is set as the 0th grade to front-wheel Wf moment of torsion display unit If being forced property of display level.Then, in moment t7, speed is in threshold
It is worth following state during time T5 to continue, thus, pulverised condition 3 becomes invalid, enforceable 0th grade of setting quilt
Release.
It is optimal to first carry out " the 3rd exception in above-mentioned " the 1st Exception handling ", " the 2nd Exception handling " and " the 3rd Exception handling "
Processing ", " the 2nd Exception handling " preferentially then is performed, finally perform " the 1st Exception handling ", thereby, it is possible to prevent these three exceptions
