The application is that application number is " 200310123129.3 ", and denomination of invention is " rewriting control device of onboard program ", and the applying date is the dividing an application of application on Dec 19th, 2003.
Technical field
The present invention relates to a kind of device of rewriting the control of onboard program.
Background technology
In the building machinery of exploitation in recent years, be equipped with the clocking value (accumulative total working time) of the present position of collecting car body, supporting instrument, be effectively or the various controllers of the car status information (to call vehicle status data in the following text) of the starting locking information of the starting blocking time section of invalid and current setting etc. in the mistake experience in esoteric past of car, in the experience in past of the esoteric error code of car, key switch accumulator terminal information of voltage, the starting locking of whether opening the present terminal voltage of key switch information, the accumulator of (in the ACC position) at present.In such Vehicle Controller, CPU is housed,, carries out calculation process according to the onboard program among the EEPROM (ROM of electric erasable) that is stored in flash memory etc., carry out vehicle-state data aggregation and with the processing of external transmission information etc.Such as, between Vehicle Controller and the external server, can keep free communication to connect by means of communication such as the Internets, the vehicle status data that Vehicle Controller is collected is sent to server.Perhaps by the attendant directly to building machinery, on Vehicle Controller, connect the home computer, vehicle status data is input to the home computer.
When upgrading vehicle-mounted program version, or when wanting to change into, be necessary that it is new onboard program that a used car that is stored in flash memory is carried program rewriting to the threshold value that produces error code on each vehicle or the error code of each vehicle etc. is judged unusually.
In patent documentation 1 (TOHKEMY 10-212739 communique), put down in writing relevant building machinery, when the controller that is used for the collection work data is housed, away from the place monitoring arrangement with server capability has been installed.So, utilize communicator to connect controller and monitoring arrangement that these collection work data are used, according to the requirement of monitoring arrangement, rewrite the interior operational data handling procedure of controller that the collection work data are used.Promptly send new operational data handling procedure from monitoring arrangement after, the collection work data in the starting building machinery with the rewrite control program on the controller ROM, are begun to rewrite and handle, new operational data handling procedure temporarily is kept among the RAM.Then, from RAM to EEPROM, the operational data handling procedure that transcription is new, thus system's control is transferred to new operational data handling procedure.
In the vehicle status data of in building machinery, collecting, the clocking value of supporting instrument (accumulative total working time), be can not be along with rewriting the data of handling and resetting with continuity at the esoteric error logging in the past of car etc.As the RAM of the interior magazine of Vehicle Controller, be low capacity mostly.Though considered the enough data capacities of this RAM during design, because the increase of the size of code that the increase of function afterwards causes, as perform region, temporary realm, the capacity that can use is along with the increase of function diminishes in RAM.Therefore, in the time of being rewritten into new onboard program, though new onboard program can temporarily be stored in the perform region of RAM, because the deficiency of perform region residual capacity, high capacity onboard program that might be new can not positively be cached to the perform region of RAM.
This point though put down in writing the situation that relevant new operational data handling procedure temporarily is stored into RAM, is not documented in and has successional operational data on the same RAM and how to be retained on the RAM in patent documentation 1.
When using usually, the controller that the collection work data are used in the building machinery then, according to the requirement of monitoring arrangement, is sent to monitoring arrangement to the operational data after handling according to operational data handling procedure collection work data and processing.When rewriting, carry new operational data handling procedure from monitoring arrangement to building machinery, make that old operational data handling procedure is rewritten into new operational data handling procedure in the controller that collection work data in building machinery use.
From being in long-range server (monitoring arrangement) with the onboard program process in the remote control rewriting building machinery, the situation that communication abnormality or communication are hung up takes place sometimes.If take place unusually in rewriting the onboard program processing procedure, onboard program is after this inoperative so, and self has lost function Vehicle Controller, can not collect the situation of vehicle status data in the time of might appearing at common utilization.Particularly when rewrite handling with Remote, when each time communication abnormality or communication taking place and hang up, must arrive far building machinery scene by the attendant, change, the shop truck set controller.Therefore, not only greatly reduce the work efficiency of building machinery, in order to recover normal, need cost great amount of manpower, time, energy simultaneously.
Because the data volume of onboard program reaches the hundreds of kilobyte, and is very big, when server (monitoring arrangement) transmitted onboard program with many building machinery as object, because the confusion of communication line, rewriting to handle needed for a long time.At this time, taken because communication line rewrites the signal post of processing, long-time situation of interrupting can appear in the communication that utilization processing usually might occur.This point is not pointed out relevant because communication line is rewritten the shared problem that causes of processing and prevented measure in patent documentation 1.
If the elements such as RAM in the Vehicle Controller have abnormal occurrencies such as damage, so, in the onboard program process in the far local remote control rewriting building machinery of distance server (monitoring arrangement), itself loses function Vehicle Controller, when using usually, vehicle status data might can not be collected.Particularly Vehicle Controller according to onboard program, possesses the function that the lock release order is started in output for the starting locked loop, if but Vehicle Controller has lost function, just can not remove the starting locking.But, because building machinery is to work under abominable situation sometimes, so must remove the starting locking.In addition, if Vehicle Controller has lost function under the starting blocking, the attendant must reach the spot and change and could move so, so work efficiency descends significantly.Mostly building machinery is usually at remote local work, for the workplace of building machinery, exists owing to reasons such as communication disruption, rewrite to handle can not normal termination possibility.
This point is in above-mentioned patent documentation 1, and record is for rewriting the problem that how to prevent in advance under the above-mentioned unfavorable condition of appearance of handling.
Summary of the invention
At the invention of above-mentioned truth, its purpose is can reliably keep irreducible data when rewriting onboard program, on the storer of low capacity, can rewrite jumbo onboard program simultaneously just in the present invention.Even have its purpose to be in rewriting processing, to occur causing unusually also can preventing that work efficiency from descending again, avoid owing to the communication chief who rewrites processing takies the time.Further its purpose is to avoid in advance to rewrite the state of affairs that processing can not normal termination.
The rewriting control device of one of relevant the present invention's onboard program comprises the Vehicle Controller that is arranged in the vehicle; In the storage medium of the information gathering controller of Vehicle Controller, the data area of preserving vehicle status data is set; In case provide the order that is rewritten into new onboard program, earlier the vehicle status data that is kept at the data area, be written to storage areas in the storage medium, different with the data area, or preserve in the storage medium different with storage medium, carry out the rewriting that is rewritten into new onboard program then and handle; If after rewriting the processing end, just carry out the processing that the vehicle status data of preserving is written back to the data area.And in the rewriting control device of onboard program, the storage medium different with storage medium also can be with storage medium be arranged in addition storage medium in the information gathering controller, vehicle interior be arranged on storage medium outside the information gathering controller, the outside of vehicle pass through communication agency connect into the storage medium of Vehicle Controller in can the server of free communication at least one.
Constitute according to relevant, processing is irreducible at rewriting, but want the vehicle data inherited, when rewriting processing, be saved in other the storage medium, after rewriting the processing end, be written back to original data area, but reach thus on the reservoir that the wearing or featuring stage armour vehicle status data remains into the information gathering controller.
In rewriting control device, during the preservation vehicle status data, the data area also can be used as the buffer area of onboard program and uses.Constitute according to relevant, can be on the memory storage of the low capacity in the information gathering controller, the jumbo onboard program of reliable cache, and reliably carry out to rewrite and handle.
The rewriting control device of relevant the present invention's two onboard program, but comprise server, be arranged on Vehicle Controller in the vehicle, server and Vehicle Controller are connected into the communication agency of free communication; Have the changeable one-tenth of communications status, i) between server and Vehicle Controller the transmission vehicle-state common application mode, ii) the onboard program of Vehicle Controller, be rewritten as the Overtype Mode of the new onboard program that sends by server; When having onboard program to rewrite instruction from server, just switch to Overtype Mode from common application mode, in Overtype Mode, when the switching command that sends to common application mode, just be converted to common application mode from Overtype Mode.And in rewriting control device, switching command also can be based on from the signal of time movement or withdraw from signal.
Constitute according to relevant, even rewrite in the processing procedure carrying out, abnormal conditions such as communication abnormality has taken place or hang up also can reliably be started old onboard program, keep the function of information gathering controller.Therefore, can carry out common utilization really and handle, prevent because the information gathering controller has lost function, the decline of the work efficiency that causes.Because according to switching command, transfer to common application mode by Overtype Mode, so can avoid because the communication line problem that takies for a long time that the communication of rewrite handling causes, guarantee communication that common utilization is handled and do not breaking down in handling in utilization usually.
The rewriting control device of relevant the present invention's three onboard program, but comprise server, be arranged on Vehicle Controller in the vehicle, server and Vehicle Controller are connected into the communication agency of free communication; Server passes through communication agency, and when the rewriting of the onboard program of carrying out Vehicle Controller was handled, server judged whether carry out the rewriting processing of onboard program by the memory contents with reference to above-mentioned Vehicle Controller.In rewriting control device, the memory contents of Vehicle Controller also can comprise at least one in onboard program and the vehicle status data.In rewriting control device, server also can compare the memory contents of Vehicle Controller and the stored contents of source file when judging whether carry out the rewriting processing of onboard program.
Have, in rewriting control device, when server was handled in the rewriting that judges whether to carry out onboard program, vehicle status data that yet can the verification vehicle when starting of its content representation vehicle is in blocking, was not carried out to rewrite and is handled again.In rewriting control device, when server was handled in the rewriting that judges whether to carry out onboard program, vehicle status data that also can the verification vehicle when its content representation vehicle is positioned at certain location, was carried out to rewrite and is handled.
Relevant formation is applicable to the occasion of utilizing the onboard program in the long-range rewriting vehicle of communication means according to the requirement of server.According to these formations since when rewrite handling a prior calibration vehicle status data, can avoid rewriting the situation that processing can not normal termination or the unsafe condition of appearance.By the memory contents of Vehicle Controller relatively with source file, whether just can verify between the data of data that vehicle is interior and source file unanimity, can correctly judge thereafter processing according to this result.In addition, when starting is in blocking, do not carry out to rewrite and handle, so, can avoid the state irremovable situation of vehicle, and then avoid the decline of work efficiency in advance in the starting locking.

In the car body of building machinery 50, starting locked loop 55 is housed.Starting locked loop 55 is made up of relay etc., and between key switch 54,57 the starting device 56 of piloting engine.The power supply of starting device 56 is vehicle-mounted accumulators 53, and accumulator 53 also is the power supply of each controller 20,30,40.
If send starting locking setting command from engine controller 40, the relay of starting locked loop 55 is switched on, and becomes the state of setting the starting locking.Even just key switch 54 has closed (ACC position), the output voltage of accumulator 53 can not be applied on the starting device 56.Therefore, starting device 56 becomes inoperative state, makes fail to start engine 57.So if send the releasing instruction of starting locking from engine controller 40, the relay of starting locked loop 55 is disconnected, and becomes the state of removing the starting locking.Promptly because key switch 54 is closed (ACC positions), starting device 56 is just started working, and can pilot engine 57.The releasing instruction of the setting command of starting locking and starting locking according to onboard program 60, by the communication line 51 in the car body, is sent to engine controller 40 from information gathering controller 20.The setting command of starting locking and the instruction of starting lock release are when being set at present starting locking " effectively ", just from 20 outputs of information gathering controller.Judging whether to enter the time period of starting locking, is that clocking value with the calendar watch 25 in the information gathering controller 20, timer 26 is a foundation.
The information of key switch 54 closures (in the ACC position) is to pass through communication line 51 in the car body from engine controller 40, is transported in the information gathering controller 20.
Usually utilization server 2 is being managed the vehicle status data in a plurality of building machineries that comprise building machinery 50.Rewriting private server 3, is the server that Long-distance Control is rewritten onboard program 60.Usually utilization server 2 has source file 6.Be input to the up-to-date vehicle status data in the common utilization server 2, be stored in the source file 6.In addition, rewrite private server 3 and have source file 6 '.Usually data of being preserved by source file 6 in the utilization server 2 are imported into by the Internet 7 and rewrite in the private server 3, and what form the preservation content identical with source file 6 is the source file 6 ' of " duplicate ".
Below in the lump with reference to Fig. 8, illustrate relevant building machinery 50 is connected and how connects switching controls with which server.In original state, in the information gathering controller 20 of building machinery 50, setting the own IP address " ID3 " corresponding with the identification id " ID1 " of utilization server 2 usually is " effectively ", and the server identification ID " ID2 " of setting and rewriting private server 3 is corresponding, and the IP address " ID4 " of oneself is engineering noise (a common application mode).In information gathering controller 20, be set at oneself the IP address date " ID3 " of " effectively ", by communication line 51 in the car body, be transported in the communication controler 30 from information gathering controller 20.
The vehicle status data order of the building machinery 50 that requires by common utilization server 2, by industrial siding 14, ground wave base station 8, industrial siding 9, antenna 10, carry to building machinery 50 in radio communication 11 modes, then by the antenna 31 reception information of building machinery 50, these data are received by communication controler 30.Passing the data of coming, comprise server identification ID " ID1 " from common utilization server 2.In communication controler 30, be set at present IP address " ID3 ", and comprise server identification ID " ID1 " in the data that receive, just be judged as both corresponding (being that " ID1 ", " ID3 " belong to a network), set up the contact of communication, becoming can be from the state of building machinery 50 sides output vehicle status data.(the 401st step be judged as YES).
Therefore, the order of request vehicle status data, is transported in the information gathering controller 20 by communication line 51 in the car body from communication controler 30.Such as, if ask the order of the clocking value of current service instrument SMR, be transported in the information gathering controller 20, so, be kept at the clocking value of the current service instrument SMR of RAM23 data area, be transported in the communication controler 30 from information gathering controller 20 by communication line in the car body 51.Therefore, export in radio communication 11 modes,, be transported to common utilization server 2 by antenna 10, industrial siding 9, ground wave base station 8, industrial siding 14 from the antenna 31 of communication controler 30.
So-called starting locking is effective, invalid for setting, the order of the starting locking information of starting blocking time section, from the occasion of common utilization server 2 to building machinery 50 outputs, with the same manner, the starting locking information of order is set in information gathering controller 20.Even can send identical order by 2 pairs of building machineries 50 of common utilization server from each client terminal of common utilization server 2.
In building machinery 50, take place specific unusual or be in specific moment etc. during specific incident, taking place constantly in incident, unusual content of in RAM23, preserving or the vehicle status data that should regularly export etc.,, be transported in the communication controler 30 by communication line 51 in the car body from information gathering controller 20.Then, from the antenna 31 of communication controler 30, transmit (sending information automatically) with communication 11.Automatically the vehicle status data that is transmitted is transported to common utilization server 2 by antenna 10, industrial siding 9, ground wave base station 8, industrial siding 14.
Be transported to the vehicle status data of the building machinery 50 in the common utilization server 2, by from the network that belongs to common utilization server 2, each client terminal visit of promptly being connected utilization server 2 usually with the Internet 7, intranet 4, be presented on the display of each client terminal.Be transported to the up-to-date vehicle status data of common utilization server 2, when being saved to source file 6, be saved in (the 405th step) in the source file 6 ' by the Internet 7.
When having upgraded onboard program 60, or want to change owing to each building machinery generation error code, when judging the threshold value that causes unusually, the old onboard program 60 ' that is kept in the flash memory 22 is rewritten by new onboard program 60.In the following description, old onboard program 60 is cast aside with new onboard program 60 with one and is differentiated.
From rewriting private server 3, by industrial siding 15, ground wave base station 8, industrial siding 9, antenna 10, in radio communication 11 modes, carry the words of the order of the onboard program 60 of rewriting building machinery 50 to building machinery 50, the antenna 31 of building machinery 50 arrives this data delivery in the communication controler 30 with regard to reception information.Carry the data of coming from rewriting private server 3, comprise server identification ID " ID2 ".In communication controler 30, be set at present IP address " ID3 ", in the data that receive, comprise server identification ID " ID2 ".Therefore, be judged as both not corresponding (because of " ID2 ", " ID3 " are not same networks), cut off and to communicate to connect (the 401st step be judged as NO).
Inconsistent this information that communicates to connect of having cut off owing to identification id is transported in the information gathering controller 20 by communication line in the car body 51 from communication controler 30.After receiving this information, in information gathering controller 20, the IP address " ID4 " of oneself corresponding with the server identification ID " ID2 " that rewrites private server 3, be switched to " effectively ", the IP address " ID3 " of oneself corresponding with the server identification ID " ID1 " of common utilization server 2 is switched to engineering noise (Overtype Mode).In information gathering controller 20, be set to oneself the IP address date " ID4 " of " effectively ",, be transported to (the 402nd step) in the communication controler 30 by communication line 51 in the car body from information gathering controller 20.
After rewriting private server 3 receives the incident of having cut off communication, send the rewriting order once more to building machinery 50.Carry the data of coming from rewriting private server 3, comprise server identification ID " ID2 ".In communication controler 30, owing to set current IP address " ID4 ", in the data that receive, comprised server identification ID " ID2 ", so being judged as both corresponding (is " ID2 " and " ID4 ", belong to same network), set up the contact (the 403rd step was judged as YES) of communicating by letter.Afterwards, be prerequisite to remove certain condition, according to from rewriting the order that private server 3 is come, in information gathering controller 20, (the 404th step) handled in the rewriting of carrying out onboard program 60.
As mentioned above, according to present embodiment, between each server of building machinery 50 and so-called common utilization server 2, rewriting private server 3, can communicate the switching of connection.Therefore, as shown in figure 10, as many building machineries 50,50a, 50b ... the time, set up certain building machinery and use communicating to connect between the server 2 usually, carry out when utilization is handled usually, can set up other building machinery therewith synchronously and rewrite communicating to connect between the private server 3, rewrite processing.Therefore, eliminated because the problem of occupying communication line that server overload and transmitted data amount big program cause, just data between transmission server and many building machineries stably.
Fig. 2 has represented to rewrite the treatment scheme of onboard program 60 according to the order of rewriting private server 3.The recovery control of relevant application mode usually is described.As shown in Figure 2, in the 403rd step of Fig. 8, communicate to connect (the 101st step of Fig. 2) if set up between building machinery 50 and the rewriting private server 3, so, timer 26 is set in acquisition of information controller 20, carries out timing task (the 102nd, 108,109 step).The setting-up time of timer 26 is to rewrite to handle the time T of setting after required time is allowed some leeway at this moment.
What information gathering controller 20 carried out is the multi-task operation, and timing task and other tasks are promptly rewritten task (the 103rd～107 step) and worked alone.Therefore, even other tasks go wrong, and the timing task is still operated accurately, and according to oneself reset processing, the starting used car carries program 60 ' becomes possible (the 109th step).When rewriting task (～107 steps of the 103rd step) normal termination, timer 26 was eliminated before surpassing the time T of setting, and was rewritten as new onboard program 60.
To this, in rewriting task (～107 steps of the 103rd step) process, if the words that communication abnormality take place or hang up; even surpass the setting-up time T of timer 26; do not stop rewrite handling (the 108th step be judged as YES) yet, carry out reset processing, start old onboard program 60 '.That is to say,, also do not stop rewriting when handling,, carry out reset processing, and switch to common utilization and handle according to switching command based on the signal of timer 26 even surpassed the time T of setting.
Communications status between building machinery 50 and the server switches to common application mode from Overtype Mode.Promptly in information gathering controller 20, revert to engineering noise with the corresponding own IP address " ID4 " of the server identification ID " ID2 " that rewrites private server 3, revert to " effectively " (common application mode) with corresponding oneself the IP address " ID3 " of the server identification ID " ID1 " of common utilization server 2.In information gathering controller 20, be set at oneself the IP address date " ID3 " of " effectively ",, be transported in the communication controler 30 by communication line 51 in the car body from information gathering controller 20.Therefore, common utilization server 2 afterwards and the communication between the building machinery 50 become possibility, also can carry out common utilization and handle (the 109th step).
As mentioned above,, in rewriting processing procedure,, also can start old onboard program 60 ' reliably, keep the function of information gathering controller 20 even communication abnormality takes place or hang up to wait unusually according to present embodiment.Therefore, can carry out common utilization reliably and handle, can prevent because information gathering controller 20 loses the decline of the work efficiency that function causes.In addition, if surpassed the time T that timer 26 is set, Overtype Mode just switches to common application mode.Based on this, can avoid because the communication of rewrite handling and for a long time to the taking of communication line, guaranteed the communication that common utilization is handled makes that utilization is not broken down in handling usually.Switching to common application mode from Overtype Mode, also can be by from being connected respectively to intranet 5 or the terminal 36 of the Internet 7 or terminal 37, exports the signal (switching command) that withdraws to rewriting private server 3 at any time and carries out.
Next the checking treatment of relevant vehicle status data is described.In the 101st step of Fig. 2, if set up communicating to connect between the communication controler 30 of rewriting private server 3 and building machinery 50, then from rewriting the rewriting order that private server 3 is brought,, be transported in the information gathering controller 20 by communication line 51 in the car body from communication controler 30.After information gathering controller 20 is received and rewritten order, in ensuing the 103rd step, carry out the processing of the current vehicle status data of verification.In the 104th step,, carry out the judgement that (rewrite whether handle may) be handled in the rewriting whether should carry out onboard program 60 according to the result of verification.
Checking treatment, the judgment processing in the 103rd step, 104 steps are to carry out in rewriting private server 3.Be that information gathering controller 20 is received and rewritten order, vehicle status data that should verification from information gathering controller 20, is transported to communication controler 30 by communication line in the car body 51.Therefore, vehicle status data that should verification from the antenna 31 of communication controler 30, is exported in radio communication 11 modes, by antenna 10, industrial siding 9, ground wave base station 8, industrial siding 15, is transported to and rewrites private server 3.
Rewriting the vehicle status data that private server 3 verifications receive, is condition all to satisfy following conditions, is judged as carry out to rewrite to handle.
Condition 1: the state that is not the starting locking;
Condition 2: building machinery 50 is not the state in the work;
Condition 3: current old onboard program 60 ' is a version of rewriting object.
As rewriting the executive condition of handling, is condition 1 because worry that information gathering controller 20 loses function in rewriting processing procedure, worries that information gathering controller 20 loses function, just can not export the order of removing the starting locking.So-called " not being the state of starting locking " is to judge according to the starting locking information that is kept in the information gathering controller 20.Such as, starting locking when being set at engineering noise and starting locking " effectively " and current time be in starting blocking time section outer the time, can be judged as " not being the state that starts locking ".
As the condition of rewriting processing, is condition 2 because of worrying that according to duty (in walking) possibility communication disruption or communication instability, rewriting processing can not normal termination in the onboard program 60 new to 50 inputs of the building machinery in the work.So-called " building machinery 50 is not the state in the work " judged according to the key switch information that is kept in the information gathering controller 20.Such as, key switch 54 is when turn-offing (leaving the ACC position), to be judged as " building machinery 50 is not the state in the work ".Whether building machinery 50 is the state in the work, also can judge according to the output voltage of verification alternator or the revolution of engine 57.
As condition, is condition 3 to handle because there is no need to carry out to rewrite.As previously mentioned, the version number of current onboard program is kept at information gathering controller 20 as vehicle status data.In addition, also can suitably increase following condition.
Condition 4: the communication terminal (communication controler 30) that is through with and begins to check;
Condition 5: accumulator terminal voltage belongs to normal scope;
Condition 6: building machinery 50 should be positioned at the local or safe place that can stably carry out radio communication 11.
As condition, is condition 4 because the preparation of management building machinery 50 is not also carried out in the server aspect.As condition, if be to exceed normal range because worry the output voltage of accumulator 53, the CPU21 of information gathering controller 20 can not steady operation, rewrite that handle can not normal termination condition 5.So-called " accumulator terminal voltage belongs to normal range ", can judge according to the accumulator terminal information of voltage that is kept in the information gathering controller 20.
As condition, is condition 6 to import in new onboard program 60 processes to building machinery 50 because of worry, and owing to communication disruption, communication instability, the rewriting processing can not normal termination.In addition, even controller has lost function, also can guarantee the safety of building machinery 50.So-called " building machinery 50 should be positioned at the local or safe place that can stably carry out radio communication 11 " is to judge according to the absolute location information that is kept at information gathering controller 20.But being not all satisfying condition 1～6 as carrying out the condition of rewriting processing, also can be any combination more than 1 or 2 in these conditions, as carrying out the condition of handling of rewriting.
Rewriting private server 3, is with reference to the vehicle status data that is kept in the information gathering controller 20, judges whether to carry out to rewrite and handles.But, in source file 6 ', because preserved the up-to-date vehicle status data of building machinery 50, so, also can judge whether to carry out to rewrite and handle with reference to the vehicle status data that is kept in the source file 6 '.Can also be in the lump with reference to being kept at the vehicle status data in the information gathering controller 20 and being kept at vehicle status data in the source file 6 ', judge whether to carry out to rewrite and handle.
Fig. 7 is illustrated in the lump when being kept at the vehicle status data in the information gathering controller 20 and being kept at vehicle status data in the source file 6 ', the treatment scheme of both data of verification.If promptly rewrite to have set up between private server 3 and the communication controler 30 and communicate to connect (the 301st step), so, by building machinery 50, information gathering controller 20 inside are answered the vehicle status data of verification, be transported to and rewrite private server 3, in rewriting private server 3, obtain data (the 302nd step).
On the other hand, rewrite private server 3 with reference to source file 6 ', obtained equally should verification vehicle status data.Therefore, with reference to source file 6 ', the vehicle status data of Huo Deing and by the inner vehicle status data that obtain of information gathering controller 20 (the 303rd step) more in advance just can be judged the two whether unanimity.Such as, according to the information of starting locking, whether the data that can judge the data of source file 6 ' and information gathering controller 20 inside consistent (the 304th goes on foot).
This result is (the 304th step was judged as Y) when the two is consistent, and the checking treatment in the 103rd step of execution graph 2 is carried out the judgment processing of whether rewriting (the 305th step) in the 104th step further.But, when the two is inconsistent (the 305th step be judged as N), the judgment processing of just interrupt later checking treatment, whether rewriting, the processing of the reason of execution analysis data exception (the 306th step).
Be judged as and carry out and rewrite when handling (the 104th step be judged as YES) when rewriting private server 3, just carry the data of its meanings of expression to building machinery 50 from rewriting private server 3.Afterwards, in information gathering controller 20, become the old onboard program 60 ' of execution rewriting and be new onboard program 60 (the 105th～107 step).But, be judged as and should not carry out and rewrite when handling (the 104th step be judged as NO) when rewriting private server 3, just carry the data of its meanings of expression to building machinery 50 from rewriting private server 3, be transported to information gathering controller 20 then.After information gathering controller 20 received these data, the situation that surpasses setting-up time T with timer 26 was identical, carried out reset processing, the old onboard program 60 ' of starting.And then the communications status between building machinery 50 and the server switches to common application mode from Overtype Mode.Therefore, after this use communicating to connect between server 2 and the building machinery 50 to become possibility usually, can carry out common utilization and handle (the 109th step).
As mentioned above, according to present embodiment because verification in advance handle the vehicle status data that adapts with rewriting, so, can avoid rewriting the situation that processing can not normal termination in advance, or the generation of dangerous situation.Particularly because can avoid information gathering controller 20 to lose function, so just can avoid the decline of work efficiency in advance at the state of starting locking.
Together with reference to Fig. 2 and Fig. 3 A～Fig. 3 F, (preservation of vehicle status data is handled) handled in the rewriting in the 105th～107 step in the key diagram 2 below.Flash memory 22 before Fig. 3 A represents to rewrite, the state of RAM23.As shown in Figure 3A, in the program area of flash memory 22, in store onboard program 60 '.And, at the in store rewrite control program 61 in the storage area of flash memory 22 (not drawing among the figure).Rewrite control program 61 is to carry out the handling procedure that old onboard program 60 ' is rewritten as new onboard program 60.RAM23 is that the data area 23b by perform region 23a, 23c and in store vehicle status data 60d constitutes.Perform region 23a, 23c are the zones of spatial capacity.
Rewrite private server 3, carry out when rewrite handling being judged as (the 104th step be judged as YES), express the data of its meaning,, be transported to building machinery 50 in radio communication 11 modes from rewriting private server 3 by industrial siding 15, ground wave base station 8, industrial siding 9, antenna 10.Then, antenna 31 receptions by building machinery 50, are transported in the information gathering controller 20 by communication line 51 in the car body from communication controler 30.After receiving this information, CPU21 reads vehicle status data 60d from data area 23b shown in Fig. 3 B, and it is passed through communication line 51 in the car body from information gathering controller 20, is transported to communication controler 30.Therefore, vehicle status data 60d transmits in radio communication 11 modes from antenna 31, delivers to and rewrites private server 3.
Rewriting private server 3, is by in the storage medium 32 (with reference to Fig. 1) that vehicle status data 60d is kept at regulation in the server 3, realizes (the 105th step of Fig. 2) of preserving.Rewrite in the private server 3 if there is vehicle status data 60d to be saved in, then new onboard program 60 just from rewriting private server 3 through same path, is transported in the information gathering controller 20.After receiving this information, CPU21 arrives temporary realm 23d to new onboard program 60 temporary caches that receive shown in Fig. 3 C.Temporary realm 23d comprises that not only perform region 23a, 23c also comprise data area 23b.Though the capacity of promptly new onboard program 60, be mostly and the suitable size in the whole zone of RAM23, but owing to preserved vehicle status data 60d, make it possible to data area 23b is used as the buffer area of new onboard program 60, so can be veritably on RAM23, the jumbo new onboard program 60 of buffer memory.
Be kept at the rewrite control program 61 in the flash memory 22, be copied to the storage area of RAM23 regulation, thus, system's control has been transferred to the RAM23 that is replicated and has been gone up so-called rewrite control program 61, and flash memory 22 becomes Overtype Mode.Therefore, after this shown in Fig. 3 D, according to the rewrite control program on the RAM23 61, the used car on the flash memory 22 carries program 60 ' to be rewritten by the new onboard program on the RAM23 60.Promptly to being cached to the new onboard program 60 among the 23d of temporary realm, after carrying out CRC check, new onboard program 60 be copied to flash memory 22 program area, be the zone that in store used car carries program 60 ', used car carries program 60 ' and is rewritten as new onboard program 60 (the 106th step).
Shown in Fig. 3 E, if new onboard program 60 has been copied to flash memory 22, so, express the data of its meaning,, be transported to and rewrite private server 3 by communication line 51 in the car body etc. from information gathering controller 20.After rewriting private server 3 these information of reception, the vehicle status data 60d that is saved in the storage medium 32 is flowed to building machinery 50.Vehicle status data 60d is received by antenna 31, is transported in the information gathering controller 20.After receiving this information, CPU21 carries out the processing (the 107th step) that the vehicle status data 60d that receives is written back to the original data area 23b of RAM23 shown in Fig. 3 F.
Finish if rewrite processing, CPU21 carries out own reset processing.Therefore, system's control is just transferred to flash memory 22, and flash memory 22 becomes normal mode, and the new onboard program 60 that is stored in flash memory 22 program area just begins starting., if used car carries program 60 ' and is rewritten as new onboard program 60, change sometimes the address of vehicle status data 60d.Therefore, in rewriting private server 3, preserve during the vehicle status data 60d, corresponding with new onboard program 60, change the address of vehicle status data 60d etc., carry out the processing of rewriting vehicle status data 60d, also can be written back to original data area 23b to the vehicle status data 60d that is rewritten.
As mentioned above, according to present embodiment, the vehicle status data 60d that inherits for the clocking value (accumulated operating time) that can not delete service instrument SMR when rewrite handling, at the needs of the esoteric wrong in the past record of car etc. is saved in the storage medium 32 of rewriting private server 3 from data area 23b rewriting when handling.Therefore, rewrite after processing finishes, because of being written back to original data area 23b, so, can be on the reservoir of information gathering controller 20, the vehicle status data 60d that inherits is wanted in reliable reservation.In addition, because the data area 23b that has preserved behind the vehicle status data 60d, use as the buffer area of new onboard program 60, so, can be on the low capacity reservoir in the information gathering controller 20, the jumbo onboard program 60 of reliable cache can positively be carried out to rewrite and handle.
In the above-described embodiment, rewrite the storage medium 32 of private server 3 though vehicle status data 60d is saved in the outside of building machinery 50, but when rewriting processing, because as long as vehicle status data 60d is saved in other storage areas or other storage mediums, so, also can preserve in building machinery 50 inside.Such as, so-called other storage area, the storage area 23e (with reference to Fig. 5 A) of RAM23 described later is arranged.In addition, so-called other storage medium, such as, the flash memory 22 in the information gathering controller 20 of Vehicle Controller 35 or the storage medium 58 (with reference to Fig. 1) of setting the Vehicle Controller 35 of building machinery 50 inside outside are arranged.
Fig. 5 A～Fig. 5 D has represented storage areas different on same RAM23, the state transformation of the storage device when preserving vehicle status data 60d.Describe with reference to the process flow diagram of Fig. 5 A～Fig. 5 D and Fig. 6 in the lump below.Shown in Fig. 5 A, be kept at the vehicle status data 60d of data area 23b, the storage area 23e that is copied to the end of RAM23 is preserved (the 201st step).Shown in Fig. 5 B,, temporarily be cached to (the 202nd step) in the temporary realm 23d that comprises data area 23b from rewriting the new onboard program 60 that private server 3 receives.
Shown in Fig. 5 C, be cached to the new onboard program 60 of temporary realm 23d, be copied to the program area (the 203rd step) of flash memory 22.After this rewriting processing finished, the new onboard program 60 that is retained in temporary realm 23d was eliminated (the 204th step).Under look like shown in Fig. 5 D, be saved in the vehicle status data 60d of storage area 23e, be written back to the data area 23b (the 205th step) of original tram.After write-back finished, the vehicle status data 60d that is retained in storage area 23e was eliminated (the 206th step).And the removing in the 204th step, 206 steps is handled and can be carried out as required, also can not remove former state prewired program, data.
In Fig. 5 A～Fig. 5 D, be vehicle status data 60d, be saved in the RAM23 that belongs to same storage medium and gone up different storage areas, also can the same manner be saved in and the different storage medium of RAM23 in the car body.Such as, as shown in Figure 1, in building machinery 50, beyond information gathering controller 20, the controller of communication controler 30, engine controller 40 etc. is installed.Therefore, when rewriting processing, pass through communication line 51 in the car body from information gathering controller 20, vehicle status data 60d, be saved in the storage medium in other controllers, after rewriting the processing end, also can be written back to original data area 23b in the information gathering controller 20 to vehicle status data 60d from other controllers.So-called other storage mediums different with RAM23, such as, as shown in Figure 1, the interior storage medium 41 of storage medium 33 in the communication controler 30 or engine controller 40 is arranged.
In the above-described embodiment, vehicle status data 60d is saved in other storage area, but has rewritten when handling, only otherwise the vehicle status data 60d that resets gets final product, might not need to be saved in other zones.Promptly as shown in Figure 4, when data area 23b is set at the zone that can not write, temporary realm 23d is set at the zone that can write.Therefore, the new onboard program 60 that transmits from rewriting private server 3, temporary cache is to the temporary realm 23d that can write, and the data area 23b buffer memory that can not write.Thus, can prevent from when rewrite handling, to be kept at the state of affairs that the vehicle status data 60d of data area 23b is reset.
In the embodiment of above explanation, imagining 2 servers is respectively that execution uses the situation of handling, rewriting processing to be illustrated usually, and common utilization is handled, rewriting is handled but also can carry out with 1 server.Such as, handle with using server 2 not only to carry out utilization usually usually, also can carry out and rewrite processing.Fig. 9 has represented to carry out the treatment scheme of switching common application mode and Overtype Mode using usually between server 2 and the building machinery 50.
At this moment, as the application program on common utilization server 2, with the communication protocol between the application program on the building machinery 50, provide the agreement of 2 transmit port layers of UDP and TCP.Therefore, according to the communication protocol of UDP, if transmit data, the then communication controler 30 on the building machinery 50 from common utilization server 2, set up being connected between the application program with UDP, make and the application program of the opposing party's TCP between be connected to invalid (the 501st go on foot be judged as Y).After receiving this information, communication controler 30 is judged as common application mode, then, carries out utilization usually by information gathering controller 20 and handles (the 503rd step).To this, according to the communication protocol of TCP, transmit data from common utilization server 2, communication controler 30 is set up being connected between the application program with TCP, make and the application program of the opposing party's UDP between be connected to invalid (the 502nd go on foot be judged as Y).After receiving this information, communication controler 30 is judged as Overtype Mode, then, carries out rewriting by information gathering controller 20 and handles (the 504th step).
In addition, when 2 servers are set, serve as main the use with one of them server, and another server also can be used as standby server use.Such as, can carry out common utilization with a server and handle and rewrite and handle, safeguard when waiting for this server but also can work as, start another pre-standby server, carry out that common utilization is handled and the rewriting processing.At this moment, the switching that communicates to connect between 2 servers and the building machinery can be suitable for the method for the above embodiments.In the present embodiment, though explanation is building machinery 50 as vehicle, the present invention to rewrite general automobile etc., the onboard program of vehicle all is suitable for arbitrarily.
