However, the regeneration energy when the vehicle in using traveling is slowing down carries out the above-mentioned of refresh charging to electrical storage device
In garbage truck as patent document 1, if short and cannot get the reasons such as sufficient deceleration time for the distance between operation field,
Cause the charge volume of electrical storage device not enough, then the voltage of electrical storage device often drops to abnormal low, and apparatus for work can not be driven.
In such case, that is, in the case of assuming that external power source can not be used, it can also be sent out in operation field by vehicle traveling engine driving
Motor, to electrical storage device forced charge.But, before electrical storage device charging to a certain degree, it is impossible to carry out operation.
Even if in addition, electrical storage device is in the state of full charge, making vehicle travel engine in operation field and stopping, only by storing
In the case that the electric power of electric installation makes apparatus for work long-time Continuous Drive, the voltage of electrical storage device, which also tends to be reduced to, makes work
The stage that industry device can not be driven.
The content of the invention
Therefore, it is an object of the present invention to which the regeneration energy in being travelled using vehicle is carried out regeneration to electrical storage device and filled
There is provided discharge the generation of gas in a kind of operation of suppression as far as possible and can suppress in operation field because electric power storage is filled in the working truck of electricity
The working truck for the state of affairs that the voltage put reduces and makes apparatus for work not driven.

Dally arresting stop, by not making idle running arresting stop work in above-mentioned usual charge mode, so that also can be in electrical storage device
Voltage be higher than can make Vidacare corp work minimum voltage assigned voltage below in the case of make electrical storage device
Charging proceeds.On the other hand, due to making idle running arresting stop work in refresh charging pattern, therefore can be for less than completely filling
Make vehicle travel engine in the case of more than the assigned voltage of the voltage of electricity to stop, can suppressing to discharge the generation of gas.
In addition, the working truck of the present invention wishes that control unit is again with the generator that engine is driven is travelled by vehicle
In raw charge mode, electrical storage device is charged by the output of generator when vehicle travels the accelerator shut-off of engine,
In usual charge mode, whether accelerator break-make, charges by the output of generator to electrical storage device.
Thus, in refresh charging pattern, when accelerator is opened（During acceleration）The load of generator is not added on vehicle row
Sail on engine, the influence travelled to vehicle can be reduced.On the other hand, in usual charge mode, due to the voltage of electrical storage device
Be reduced to higher than can make Vidacare corp work minimum voltage assigned voltage below, so no matter accelerator break-make with
It is no, electrical storage device is charged by the output of generator, thus, can carry out full charge quick to electrical storage device.

Operation is carried out under state.Therefore, in operation, compared with the garbage truck using PTO, noise is reduced, also not discharge gas.
Then, on situation that " refresh charging " is have selected by charging option switch 14c control unit 12 processing, be based on
Fig. 3 flow chart is illustrated.
Generally, control unit 12 takes the refresh charging that the regeneration energy in being travelled using vehicle is charged to capacitor 2
Pattern（Step S101）.In refresh charging pattern, if control unit 12 turns off sensor 9 in vehicle traveling by means of accelerator
Accelerator shut-off is detected, then the regenerated electric power produced by generator 6a is supplied into capacitor 2 by AVR6b, charged.Again
Have, in the case of by means of accelerator shut-off sensor 9, accelerator is turned off, not only comprising adding brake to make vehicle deceleration
Situation, also comprising making the situation of vehicle constant speed drive using inertia.
In addition, in the refresh charging pattern, control unit 12 performs the sky that vehicle travels engine 5 by idle running arresting stop 11
Turn to stop（Step S102）.Idle running stop the detection that parking brake is opened done by means of parking brake sensor 8 and
Carry out, the open signal linkage for the parking brake that idle running arresting stop 11 is done with parking brake sensor 8 makes vehicle row
Engine 5 is sailed to stop.
Then, control unit 12 monitors whether the voltage of capacitor 2 is higher than can make refuse collector 20 by monitoring arrangement 7
The assigned voltage of the minimum voltage of work（Hereinafter, it is referred to as " charge switching value usually ".）Below L（Step S103）, to be flat
Often in the case of charging below switching value L, switch to the driving energy for travelling engine 5 using vehicle and capacitor 2 is charged
Usual charge mode（Step S104）.In usual charge mode, control unit 12 turns off the detection of sensor 9 regardless of accelerator
As a result how, capacitor will be supplied by AVR6b by means of travelling the electric power produced by engine 5 drives generator 6a as vehicle
2, charged.In addition, in the usual charge mode, the vehicle traveling that the cancellation idle running arresting stop 11 of control unit 12 is done is drawn
The idle running for holding up 5 stops（Step S105）.Then, control unit 12 monitors whether the voltage of capacitor 2 is less than full by monitoring arrangement 7
The assigned voltage of the voltage of charging（Hereinafter, it is referred to as " refresh charging switching value ".）More than H（Step S106）, filled when for regeneration
In the case of electric more than switching value H, foregoing refresh charging pattern is switched to（Step S101）.
Then, the specific processing on control unit 12, reference picture 4 and Fig. 5 timing diagram are described in further detail.Figure
4 be the figure for showing the timing diagram in the case of it have selected " refresh charging " by charging option switch 14c, and Fig. 5 is shown by filling
Electric selecting switch 14c have selected the figure of the timing diagram in the case of " charging usually ".
In the case where have selected " refresh charging " by charging option switch 14c, as shown in figure 4, between a-b, in sky
Turn refuse collector 20 under halted state to work, therebetween, the voltage of capacitor 2 is with the decline of the charge capacity of capacitor 2
Straight line declines.In the interval, refuse collector 20 is to stopping since work, and the voltage of capacitor 2 maintains usual charging
More than switching value L, control unit 12 is refresh charging pattern.
Then, if releasing parking brake in c points, idle running stops to turn off, and vehicle traveling engine 5 is driven.So
Afterwards, accelerator is opens, and vehicle is in giving it the gun between e-f.Now, as it was previously stated, refresh charging pattern is in continuation, by
In not measuring accelerator shut-off by means of the accelerator shut-off inspection of sensor 9, so the charging to capacitor 2 can not be carried out.
It is accelerator is turned off and the interval in constant speed drive during vehicle is travelled between ensuing f-g.Now, due to by
In accelerator shut-off sensor 9 detect accelerator turn off, so as vehicle travel engine 5 driving in generator 6a produced by
Electric power, capacitor 2 is supplied by AVR6b, and is electrically charged.It is because accelerator is turned off and is in deceleration between ensuing g-h
Interval, similarly, since by means of accelerator shut-off sensor 9 detect accelerator turn off, so produced by generator 6a
Regenerated electric power, capacitor 2 is supplied by AVR6b, and is electrically charged.
Then, in h points, if vehicle stops, the charging to capacitor 2 also stops.In i points parking brake to open,
Idle running stops also as unlatching.
It is the interval for making refuse collector 20 work under idle stop state between ensuing j-k, in the interval, electricity
With the decline of the charge capacity of capacitor 2, straight line declines the voltage of container 2.Moreover, in k points, in refuse collector 20
The voltage of capacitor 2 in way that works is in charging below switching value L usually, and control unit 12 is from refresh charging pattern switching to usual
Charge mode.
It is to switch to the interval for also making refuse collector 20 work after the usual charge mode between ensuing k-l.
In the interval, while the usual charge mode is switched to, control unit 12 cancels the vehicle row that idle running arresting stop 11 is done
The idle running for sailing engine 5 stops, and forcibly starts vehicle traveling engine 5.Thus, generator 6a is driven by vehicle traveling engine 5,
Capacitor 2 is charged.Further, in the present embodiment, because the consumption electric power of refuse collector 20 is more than generator
6a electricity power, so the charge capacity of capacitor 2 is reduced gradually, is corresponded, and the voltage of capacitor 2 is also declining.
It is that refuse collector 20 stops under usual charge mode between ensuing l-n, vehicle travels engine 5 in idle running
The interval charged under state to capacitor 2.Then, in n points, accelerator is opens, and between n-o, vehicle is giving it the gun
In, but due in the interval, it is different between foregoing e-f, in usual charge mode, therefore carry out the charging to capacitor 2.
Further, in the interval, the charge volume of the time per unit portion higher than idling conditions than the revolution of big vehicle traveling engine 5 between l-n
Point.
Then, in o points, if the voltage of capacitor 2 is in more than refresh charging switching value H, control unit 12 charges from usual
Pattern switching is to refresh charging pattern.Now, because accelerator is opens, so the charging to capacitor 2 between o-p stops.
On the other hand, in the case where have selected " charging usually " by charging option switch 14c, no matter parking brake
Whether is break-make, and idle running stopping is shut-off, and vehicle traveling engine 5 is driven.Therefore, as shown in figure 5, between a '-b ', rubbish
Collection device 20 also charges to capacitor 2 at work.Further, in the present embodiment, due to the consumption electricity of motor 4
Power is more than generator 6a electricity power, so the charge capacity of capacitor 2 is reduced gradually, corresponds, the voltage of capacitor 2
Also decline.
It is that refuse collector 20 stops between ensuing b '-c ', vehicle travels engine 5 in the idling condition to capacitor
2 intervals charged.Hereinafter, in the case of by charging option switch 14c selections " charging usually ", to capacitor 2
Charging proceeds.
Further, in the present embodiment, either above-mentioned usual charge mode or refresh charging pattern will not be with
The full charge of capacitor 2 turns off the work of direct-current generating device 6 as triggering.So, even if also to electric capacity after full charge
Device 2, which continues to charge, not to be a problem yet, because above-mentioned direct-current generating device 6（AVR6b）Upper voltage limit control function rise
The reason of effect.That is, due to by making direct-current generating device 6（AVR6b）Rated output voltage and capacitor 2 desired by
Full charge voltage is consistent, so as to reach poised state when capacitor 2 is full charge, therefore can prevent on the voltage of capacitor 2
Rise to more than the full charge voltage set.
Processing that can be by more than is summarized as follows.
To the charge timing of capacitor 2
<The situation of refresh charging pattern>
Charging to capacitor 2 is carried out when following 3 conditions are complete：
Vehicle speed sensor 10 is opened
Accelerator shut-off sensor 9 is opened
Parking brake sensor 8 is turned off
That is, in the acceleration of vehicle, engine 5 is travelled to vehicle due to can at least mitigate
Load, therefore to the charging of capacitor 2 without.On the other hand, vehicle is carried out because inertia is in constant speed drive
Charging to capacitor 2.For the load caused by the generator 6a that is charged to capacitor 2 due to travelling engine 5 with vehicle
Driving force is compared less greatly, therefore the charging in the constant speed drive is possibly realized.In addition, in the deceleration of vehicle, due in hair
Regenerated electric power is produced in motor 6a, therefore capacitor 2 is charged with the regenerated electric power.In addition, in the parking of vehicle, in idle running shape
Even if vehicle traveling engine 5 drives under state, to the charging of capacitor 2 also without.
<The situation of usual charge mode>
Charging to capacitor 2 drives in vehicle traveling engine 5 and carried out usually during generator 6a work.
（B）The timing that idle running stops
<The situation of refresh charging pattern>
The execution and its releasing that idle running stops can for example be performed as follows.
Idle running stops performing
Parking brake is opened
Idle running stops releasing
Parking brake is turned off
<The situation of usual charge mode>
Idle running is set to stop function stop.That is, even if vehicle parking, idle running stops also not performing.
The switching timing of refresh charging pattern and usual charge mode
The voltage of capacitor 2 has lower limit and higher limit.Lower limit is the motor 4 of the driving of refuse collector 20
It is changed into idle voltage（The motor driver of converting means 3 is changed into idle voltage）.Higher limit is that capacitor 2 is changed into
The voltage of full charge.Refresh charging switching value H and usually charging switching value L are set between the higher limit and lower limit.
It is higher limit in the voltage of capacitor 2（Full charge）In the case of, take refresh charging pattern.In capacitor 2
Voltage is from higher limit（Full charge）State make in the case that refuse collector 20 drives, the voltage of capacitor 2 stores with it
The decline of electricity and straight line declines.Then, if the voltage of capacitor 2 is less than charging switching value L usually, from refresh charging pattern
Switch to usual charge mode.In addition, in the state of usual charge mode is taken, capacitor 2 is charged, capacitor 2
If voltage exceed refresh charging switching value H, switch to refresh charging pattern from usual charge mode.
As described above, in the garbage truck of present embodiment, the regeneration energy being usually taken in being travelled using vehicle is carried out
The refresh charging pattern of charging carries out the charging of the capacitor 2 of the electric power to accumulating drive motor 4, but when capacitor 2
When voltage is reduced to below the assigned voltage L higher than the minimum voltage that can make the work of motor 4, by switching to charging mould usually
Formula, thus using vehicle travel engine 5 driving energy capacitor 2 is charged, when rise to be less than full charge voltage
More than assigned voltage H when, switch to refresh charging pattern.Therefore, even only by make use of the Regenerated energy in vehicle traveling
The charging of amount, the not enough such situation of charge volume of capacitor 2, prevented also from the electric voltage exception of the capacitor 2 of drive motor 4
Ground is reduced, and makes it possible that the charge volume of capacitor 2 quickly accomplishes full charge, when making vehicle parking, because capacitor 2 is full
Charging, relatively carries out making it possible that vehicle travels the operation that engine 5 stops for a long time.
In addition, in the garbage truck of present embodiment, making vehicle row with being linked with the open signal of parking brake
The idle running arresting stop 11 of the stopping of engine 5 is sailed, control unit 12 makes idle running arresting stop 11 work in refresh charging pattern, flat
Due to not making idle running arresting stop 11 work in normal charge mode, so can be higher than motor 4 can be made in the voltage of capacitor 2
During below the assigned voltage L of the minimum voltage of work, proceed the charging of capacitor 2.On the other hand, in refresh charging mould
In formula, due to making idle running arresting stop 11 work, therefore in the case of for more than the assigned voltage H less than the voltage of full charge,
