Sent to electrical storage device 101 by the judged result 117 that electric power is assisted decision systems 116 or possess electric power storage dress The electric power put provides equipment 103, thus carries out the electric power from electrical storage device and provide.
Fig. 2 illustrates that electrical storage device judges the concrete handling process of system 112.
In step 201, based on current vehicle location, according to away from vehicle order from the near to the remote, to possessing electric power storage dress The electric power put provides source to classify, and starts to be set to 1,2 in order from nearest position ... n, and enters step 202.
If it addition, the distance between vehicle with electrical storage device excessively separates, then due to the electricity caused via long stringing Power loss becomes big, additionally, other vehicles are just carrying out the probability of regenerative braking and are also uprising betwixt, thus to be searched to possessing The electric power of electrical storage device provides source to arrange apart from upper restriction.
In step 202., if K (searching ID)=1, step 203 is entered.
In step 203, it is determined that electric power provides whether the SOC (electric power storage state) in source (K) can carry out electric power offer State, if it is possible to carry out electric power offer, then enter step 204, if electric power offer can not be carried out, then enters step 205.
In step 204, source (K) is provided to send output order to electric power.Leave it at that.
In step 205, the K of the search ID providing source as electric power is set to (K+1), enters step 206.
Additionally, in step 206, it is judged that the upper limit (n) providing the K ＞ electric power of the search ID in source to provide source as electric power is No establishment, if K exceedes electric power and provides the upper limit in source, is then set to there is not the electrical storage device that can carry out electric power offer, and ties Bundle processes, if K is not above electric power and provides the upper limit in source, then returns to step 203, continues to search for carrying out electric power offer Electrical storage device.
Processed by above, it is possible to judge that system 112 calculates by electrical storage device and recently and can carry out with away from vehicle The 1st judged result 114 that the electrical storage device that electric power provides is relevant.
Fig. 3 illustrates the concrete handling process of electric power auxiliary judgement system 113.
In step 301, it is judged that whether vehicle-state is during power runs, if during power runs, then entering step 302, in running if not power, then enter step 304.
In step 302, it is determined that whether the car speed being included in car status information has exceeded V/f terminal velocity, In the case of having exceeded, enter step 303 and carry out output request.
On the other hand, if car speed is below V/f terminal velocity, then enter step 304, do not carry out output request, End processes.
It addition, so-called V/f terminal velocity, refer to the stringing by carrying out the state before electric power auxiliary by electrical storage device Acceleration is maintained terminal velocity that is fixing and that obtain by voltage.
Fig. 4 illustrates the concrete handling process of electric power auxiliary decision systems 116.
In step 401, it is judged that provide between source and vehicle at the electric power that determined, have invariably possess electrical storage device and only Being the electric power offer source of transformer station, the electric power without Jin Shi transformer station provides source, then entering step 402, if had being only The electric power of transformer station provides source, then enter step 403.
In step 402, sending the electrical storage device electric discharge in the electric power offer source that instruction makes to meet, end processes, in step In 403, owing to not making to provide the electrical storage device in source to carry out discharging so not sending instruction from electric power.Leave it at that.
By above process, by being in the case of power runs and exceeded V/f terminal velocity at vehicle, from ground Face electrical storage device release electric power such that it is able to promote stringing voltage.
Such as, if as it is shown in figure 5, the car speed under setting reference voltage is β as α, the car speed after acceleration, and sets By stringing voltage increase to reference voltage × beta/alpha, then the acceleration of vehicle brings up to pattern a from pattern a '.
Railway due to schedule it has been determined that so by improve acceleration, the inertia force time can be caused to increase, therefore It is capable of energy-conservation.Use Fig. 6 and Fig. 7 that the state all the time applied in the case of this control is shown.
As simply example, Fig. 6 assume AT STATION between route on exist and be respectively provided with 2 electric power of electrical storage device and carry Supply source 1 and 2 and the electric power that is only made up of transformer station the situation in source 3 is provided.
Advance on the route of Fig. 6 additionally, Fig. 7 sets 1 train, it is shown that in the case of applying the control of the present embodiment All the time state.
Illustrate in order on from [time m-speed], [time m-V/f speed judge], [time m-power run judge], [time the m-distance that source is provided with electric power], [time m-electric power provide source 1 to instruct], [time m-electric power provide source 2 to instruct], [time M-electric power provides the SOC in source 1], [time m-electric power the SOC in source 2 is provided], the relation in [time m-vehicle stringing voltage].It addition, About solid line, in the relation in [time m-speed], solid line represent the situation of the control employing the present embodiment, by dotted line Represent the situation of the control not using the present embodiment, but be set to fix by both time integral values, in order to running time Table does not changes.
These curve charts temporally carry out region segmentation illustrate.
Time zone A represents that vehicle carries out power operation from station and speed is V/f terminal velocity area below Situation.In this case, if according to the handling process of Fig. 3, then not providing request to the electric power of electrical storage device, vehicle enters The action that row is identical with not using control.
Then, if car speed is more than V/f terminal velocity, then time zone B it is transferred to.
In time zone B, owing to car speed has exceeded V/f terminal velocity, so according to the handling process of Fig. 2, only Be electrical storage device electric power provide source 1 than possess electrical storage device and transformer station both sides electric power provide source 2 away from vehicle location closer to, Additionally, the SOC that electric power provides the electrical storage device in source 1 is also enough, according to the handling process of Fig. 4, electric power provides source 1 to be power transformation than only The electric power stood provide source 3 closer to, so providing source 1 to send instruction to electric power.
Additionally, according to the handling process of Fig. 3, owing to being during power runs and car speed has exceeded V/f terminal velocity, So carrying out providing the request in source to electric power.
Thus, providing source 1 to carry out electric discharge instruction to electric power, the stringing voltage of vehicle rises, and power runnability rises, and adds Speed is enhanced.But, it being accompanied by this, electric power provides the SOC in source 1 to be gradually reduced.
Then, if vehicle enters inertia force and runs, then time zone C it is transferred to.
In this case, according to the handling process of Fig. 3, do not carry out providing the request in source to electric power.Thus, electric power provides source 1 and electric power provide source 2 SOC do not change.Then, if vehicle is again introduced into power and runs, then time zone it is transferred to D。
