Specific embodiment

For existing communication control system as shown in Figure 1, it was found by the inventors of the present invention that 1 mould of SW (Software) These three communication request modules with communication requirement of block, SW2 module and SW3 module, to NM (Network Management, network management) 1 module and Com (Communication, communication) module has control to require；SW2 module and SW3 The two communication request modules of module have control to require NM2 module；SW3 module and NM2 module are to CAN2 (Control Area Network, controller LAN) module have control require；SW1 module, SW2 module, SW3 module, NM1 module and NM2 Module has control to require Com module.In this way, when SW1 module, SW2 module and SW3 module these three communication request modules State changes, and variation sequence is different, it will cause to generate conflict to the use of same communication channel simultaneously, that is, It says, the coupling between each communication request module in the existing this network architecture is larger, when causing to do code migrating, work Amount is big, and difficulty is high.

Wherein, NM1 module and NM2 module can be network management module, for managing SW1 module, SW2 module and SW3 Transmission/reception of the unlatching/closing and the communication channel of communication channel needed for module executes to message；This communication of Com module Module can be management message and send/received module, and the present embodiment can be denoted as message management module, CAN1 module and CAN2 module can be driving network message transmission/received module, be properly termed as CAN drive module, in practical applications, can To connect different communication channels.

In order to improve the above problem, the present inventor proposes to adjust the network architecture as shown in Figure 1, and reduction respectively has Coupling between the communication request module of communication requirement, finds by continuously attempting to, and a communication management module can be set ComM (Communication Manager), to be managed collectively the communication requirement and message management mould of each communication request module SW Reception/transmission of the block Com to message data, and a network management integration module NmIn (Network management is set Integrate), the communication requirement of each communication request module SW is uniformly responded, controls multiple network management module NM, triggers phase The CAN drive module answered, at least one corresponding communication channel of unlatching/closing, to terminate each communication request module SW to network Management module NM's and message management module Com directly controls requirement and each network management module NM to message management module Com's directly controls requirement, to reduce the dependence between each communication request module SW, that is, reduces each communication request mould Coupling between block SW, and then improve code portability.

It is to be appreciated that the present invention does not do the network architecture of the new communication control system obtained based on above-mentioned core idea It limits.

In order to keep the above objects, features and advantages of the present invention more obvious and easy to understand, below in conjunction with of the invention real The attached drawing in example is applied, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described implementation Example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common Technical staff's every other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.

Referring to Fig. 2, the communication control system provided in an embodiment of the present invention for being used to realize communication control method is shown Network architecture diagram, the core idea based on the above described for constructing the System Network Architecture, as shown in Fig. 2, the system can wrap It includes but is not limited to following functions module:

Multiple communication request module SW are (as SW1, SW2 and SW3 in Fig. 2 have communication requirement under operation Software function module), multiple network management module NM (NM1 and NM2 in such as Fig. 2), with multiple network management module NM mono- One be correspondingly connected with multiple CAN drive modules (CAN1 and CAN2 in such as Fig. 2), message management module Com, and connect respectively The communication management module ComM of multiple communication request module SW (SW1, SW2, SW3 in such as Fig. 2), message management module Com is met, It is separately connected the network management integration module NmIn of communication management module ComM and multiple network management module NM.From system structure From the point of view of, relative to the network architecture shown in figure 1 above, the present embodiment will be multiple communication request modules by communication management module ComM SW provides unified telecommunication management interface, as shown in Fig. 2, multiple communication request module SW are by original network structure, directly with The connection of network management module NM, message management module Com or CAN drive module, be changed to only with the communication management module ComM connection, then other modules are connected by communication management module ComM, it is then by network pipe for network management module NM Reason integration module NmIn is connect with communication management module ComM, and the CAN drive module that connects one to one, so that network management Module NM, CAN drive module and message management module Com are no longer directly controlled by communication request module SW, and message pipe Reason module Com is also no longer directly controlled by each network management module NM, communication request module SW.

As it can be seen that the communication control system for the network structure as shown in Figure 2 that the present embodiment proposes, greatly reduces each communication Request module SW, network management module NM, the correlation degree between message management module Com and CAN drive module, that is, reduce Coupling between communication request module SW, improves code portability.

The network architecture of communication control system provided in this embodiment based on the above described, will be by communication management module ComM is according to the request content of the communication request of the multiple communication request objects currently listened to, such as communication channel of request communication And communicating requirement etc. is opened or closed to the communication channel, according to object priority weighing mechanism, decide whether to request network It manages integration module NmIn and responds communication request, be specifically in response to the communication request of which communication request object, response communication is asked Asking may include opening or closing the corresponding network communicating function of network management module NM, enable/forbidden energy message management module Com Whether send/receive message.

It, will be according to as it can be seen that the present embodiment is listening to there is currently in the case where the communication request of multiple communication request objects According to the processing priority of each communication request object, determines and the response for responding corresponding multiple communication requests is handled, rather than press According to the generation sequence of each communication request, communication request is successively responded, ECU work at present requirement is met, avoids different communication Request the communicating requirement to same communication channel on the contrary, causing to use collision problem to the communication channel.

Such as, SW1 module is power management software, and when preset high-pressure forbids communicating；SW2 module is that ignition switch acquisition is soft Part enables communication when default ignition switch is in effective status.According to the network architecture shown in FIG. 1, if high pressure first occurs for ECU Failure, then ignition switch is in effective status, and system can enable to communicate, forbid communicating when this is with preset high pressure and violate；If ECU ignition switch is first in effective status, then occurs high voltage fault, and system can control communication in disabled state, this with it is pre- If ignition switch when being in effective status enabled communication disagree.

System is built according to the network architecture as shown in Figure 2 at this time, the same time listens to power management software module High voltage fault occurs, ignition switch is in effective status, and the present invention will be according to the two communication request object priority height, first The communication request of the higher communication request object of processing priority, if the preferential of this communication request object of high voltage fault occurs Grade is higher, even if there is the communication request to same communication channel before this, also can first respond this communication request object Communication request forbids communicating, the communication function in communication close channel, and transmission/reception of forbidden energy message, solves above-mentioned existing The technical issues of with the presence of communication control scheme.

The network architecture of the communication control system in conjunction with shown in figure 2 above, it is real that the invention proposes a kind of communication control methods Apply the flow diagram of example, this method can be applied to the equipment such as Vehicle Controller, as shown in figure 3, this method may include but It is not limited to following steps:

Step S11 listens to the communication request of communication request object；

In the present embodiment, can will control communication channel open or close, enabled/forbidden energy message send/it is received Object can cause communication interface state to change, or the object that triggering communication channel opens or closes, and be denoted as communication request Object.The communication request of communication request object can refer to that request opens or closes the communication function requirement of communication channel, and make Energy/forbidden energy message transmission/reception, this can be determined according to the communication feature for being directed to each communication request object existing for ECU in advance, The present embodiment to the communication request content of each communication request object without limitation.

Referring to Automobile Network System framework shown in Fig. 4, entire Automobile Network System is segmented into several networks, if this A dry network can connect into vehicle network by gateway Gateway, as shown in figure 4, whole network can by CAN interface or LIN (Local Interconnect Network, local interconnect network) interface, realizes the communication between each sub-network, these Sub-network may include the Powertrain (power drive system) connected by different CAN interfaces, Diagnostics (diagnosis System), Comfort (comfort mode, i.e. running car mode) and Infotainment (vehicle multimedia system) etc., this four The functional module that sub-network specifically includes is as follows, but is not limited to functional module enumerated herein:

It may include ESP (ElectronicStabilityProgram, electronic stability control system in Powertrain system System), TCU (Transmission Control Unit, automatic gear-box control unit), EMS (Engine Manegement System, engine management system) and AFS (Adaptive Frontlighting System, adaptive lighting system), and The AFS control system can connect Lamp Motor (lampshade motor) by LIN interface；Diagnostics system may include Diag Tool (system diagnostic tools)；Comfort system may include BCM (body control module, car body control module), The BCM can also include the Rain Sensor (precipitation rain fall sensor) connected by LIN interface；Infotainment system can be with Including NAV (Navigation, navigation).

In conjunction with auto communication control field common sense, each network as shown in Figure 4 can include several I/O equipment, lead to Believe interface (such as above-mentioned CAN interface or LIN interface), the control opened or closed for communication interface depends not only on I/O and sets Standby state might also depend on the network state of each network, and therefore, the communication request object that the present embodiment listens to can wrap The various events with communication requirement are included, the condition with communication requirement is also possible to.

The communication request object of the Automobile Network System as shown in figure 4 above, the present embodiment can be unlatching ignition switch (an I/O equipment i.e. in power drive system) event, the condition determined by network state, such as certain network in CAN bus Node sends network management message etc..

Optionally, communication request object can determine that the requirement description file can be with based on the requirement description file of client Description comprising opening or closing condition or event to communication channel, therefore, the present embodiment can will be in the requirement description file Description, there are the condition of communication requirement and event to be denoted as communication request object, and extract these communication request objects, supervises accordingly Listen whether telecommunication management interface receives the communication request for these communication request objects.

It can be before project starts it is to be appreciated that the demand describes file, client controls automobile according to itself Demand determine, the present embodiment to it includes particular content be not construed as limiting, for different types of client, determine The content of requirement description file may be different, the content of thus obtained communication request object may also difference, the present invention This is not described further.

And above-mentioned telecommunication management interface can be the data of the communication management module ComM in the network architecture shown in Fig. 2 Interface, the present embodiment to the type of the telecommunication management interface and to its monitor method without limitation.

Step S12 parses each communication request listened to, obtains the object ID of respective communication request object；

The present embodiment can predefine each communication request object present in network system with communication requirement, be every One unique object ID of communication request object distribution, the number such as since 0, i.e., 0,1,2 ... etc..In this way, in the present embodiment, Respective object ID request communication management module ComM can be used in each communication request object, by monitoring the communication management module The communication request of the telecommunication management interface of ComM, each communication request object listened to can carry object ID, parse the communication Request, the object ID of the available each communication request object listened to.

Step S13, from the information configuration table prestored, it is right correspondingly with the object ID of each communication request object to obtain As type and communication attributes；

It, can be based on the specific communicating requirement of communication request object, to multiple communication requests pair in ECU in the present embodiment As classifying, obtain multiple object types, can be denoted as respectively Lock (locking) object (or being denoted as the first object), Local (local) object (the second object can also be denoted as), Remote (long-range) object (or being denoted as third object) and Disable (disability) object (the 4th object can also be denoted as).

Wherein, the communicating requirement of Lock object, which can be, closes certain communication channel；The communicating requirement of Local object can be The local communication of some communication channel is opened, i.e., carries out local communication using certain communication channel；The communicating requirement of Remote object It can be the telecommunications functions for opening some communication channel, i.e., carried out telecommunication using some communication channel；Disable pairs The communicating requirement of elephant can be the message transmission/reception for closing some communication channel, that is, forbid certain communication channel transmitting message number According to.

As it can be seen that the communicating requirement of different types of communication request object is often different, in the present embodiment practical application, The object type that can first determine the communication request object listened to is rung according still further to the communicating requirement of the preset object type Should communication request object communication request.

It may include channel attributes and message attribute for the communication attributes for the communication request object that the present embodiment proposes. Wherein, the channel attributes of communication request object can characterize which communication channel of the communication request object control, and message attribute can Message/network management message is applied to characterize communication channel reception/transmission.

Under normal conditions, communication channel (i.e. network channel) quantity of ECU is greater than 1, controls each communication channel for convenience, Can for each communication channel distribute a unique logic channel number, such as 0,1,2,3 ..., due to ECU communication channel quantity often No more than 32, therefore, the present embodiment can indicate channel attributes with one 32 hexadecimal integers, by be converted into two Each bit value in system number indicates whether communication request object allows to control unlatching/closing of corresponding communication channel, such as Numerical value 1 on certain can indicate that communication request object has the control of corresponding communication channel.

Such as, the channel attributes of communication request object are 0x000C, and after being converted into binary number due to it, each indicates one A communication channel, 0 expression logical communication channel 0 of ascending the throne, position 1 indicate logical communication channel 1, and position 2 indicates logical communication channel 2, Position 3 indicates logical communication channel 3 ... ... etc., can learn that position 2 and position 3 are set to 1 by the binary number of the channel attributes, so It says, the communication request of communication request object affects the communication of logical communication channel 2 and logical communication channel 3, realizes to communication The method of the communication control in channel is without limitation.

Optionally, it for the message attribute of communication request object, can be indicated with one 8 hexadecimal integers, position 0 (i.e. least significant bit) indicates to apply the transmission of message, and position 1 indicates to apply the reception of message, and position 2 indicates network management message It sends, position 3 indicates the reception of network management message.

For example, if the message attribute of communication request object is 0x05 (corresponding binary number be 0101), Bit0 and Bit2 set 1 indicate the communication request object initiate communication request when, forbid answering for which channel specified by its channel attributes With the transmission of message and network management message.

In conjunction with the analysis above to channel attributes and message attribute, above-mentioned communication attributes can be used to refer to communication request pair Any type sent/receive as which or the multiple communication channels unlatching/closing that can be controlled, and using the communication channel Message multiple numbers, the meaning is specifically indicated by numerical value on different positions, be specifically referred to above to channel attributes and The analysis of message attribute, the meaning that the present embodiment no longer indicates the numerical value on each position in the communication attributes are illustrated.

In the present embodiment practical application, multiple communication request objects with communication requirement that may be present for ECU, The object type and communication attributes of each communication request object can be predefined, and sets object ID for it, is stored to information In allocation list, therefore, in the communication request for listening to communication request object, and the object ID of each communication request object is determined Afterwards, can be searched directly from information configuration table with the object type and communication attributes of one an object of object ID, as currently The object type and communication attributes of the respective communication request object listened to.

As it can be seen that information configuration table may include the communication request object of different object types, communication control specifically how is realized System includes how opening or closing for each communication channel of control ECU, and how to realize transmission/reception of message.The present embodiment It without limitation to the generation method of the information configuration table, specifically can be using the generation side of the hereafter description of corresponding embodiment Method.

Step S14 weighs machine according to object priority based on the object type and communication attributes of each communication request object System, responds the communication request of each communication request object.

In the present embodiment practical application, if listening to current time there are the communication request of multiple communication request objects, And the communication attributes of each communication request object by obtaining, determine the communication request that there is communication requirement to same communication channel The quantity of object be it is multiple, the present embodiment, can be according to different right after the object type for obtaining this multiple communication request object As the communication attributes of the communication request object of type, the excellent of the communication request for handling the communication request object of each object type is determined First grade, i.e. generation object priority weighing mechanism, the present embodiment does not limit for specific generation method.

Optionally, there is the preferential of multiple communication request objects of communication requirement to same communication channel in the present embodiment Grade, can be set according to communication request object type, as the sequence of priority from high to low successively may is that Lock object, Local object, Remote object, Disable object.Therefore, when there are the communication request objects of multiple object types by ECU, and It, can be according to setting in the case that current time has communication requirement to the same communication channel there are multiple communication request objects Each object type communication request object processing priority, to the communication requests of the multiple communication request objects listened into Row processing.

Wherein, current time has multiple communication request objects of communication requirement to the same communication channel, can be simultaneously Communication request is initiated, communication request can also be initiated in different moments, but because the communication request of initiation does not discharge, so that currently There are multiple communication requests for the communication channel in the moment, in order to avoid the use conflict to the communication channel, the present embodiment Multiple communication requests existing for current time will be handled according to object priority weighing mechanism.It is to be appreciated that in the object priority It is as follows to the processing requirement of the communication request of the communication request object of different object types in grade weighing mechanism:

For Lock object, usually communication management module ComM is requested to close some or multiple communication channels, when to this The communication request object for having the object type that communication channel has control to require, regardless of the communication request object of other object types There is He Yaoqiu to the communication channel, communication management module ComM can request closing to network management integration module NmIn, and this is logical Believe the communication function in channel.When there is no Lock object, communication tubes for the communication request object for having control to require the communication channel Reason module ComM can the communication request of communication request object to other object types handle.

For Local object, the local communication for opening some or multiple communication channels is usually required that.Due to its priority It is only below Lock object, in the communication request object for thering is control to require the communication channel, as long as Lock object is not present, so that it may To execute the communicating requirement of the Local object, i.e., in the case where not hearing Lock object, determination has control to the communication channel The communication request object that system requires includes Local object, and communication management module ComM can be to network management integration module The local communication function of the communication channel is opened in NmIn request；If it is determined that the communication request pair for thering is control to require the communication channel As comprising Lock object and Local object, communication management module ComM can not respond the communication request pair of other object types The communication request of elephant.

For Remote object, the telecommunications functions for opening some or multiple communication channels are usually required that, due to this The processing priority of object type is lower than Lock object and Local object, when the communication request for having control to require communication channel Lock object and Local object is not present in object, and there are at least one Remote object, communication management module ComM is ok The telecommunications functions of the unlatching communication channel are requested to network management integration module NmIn.Wherein, when Remote object is full The condition of sufficient telecommunications functions, it may not be necessary to which the request of communication management module ComM, the inside network management module NM are automatic It closes, realizes the telecommunication of communication channel.

For Disable object, usually require that closing some or multiple communication channels send/receive message.Specifically exist In the case that the local/remote communication function of communication channel is opened, i.e., after execution Local/Remote object, to the communication channel The communication request object for having control to require includes at least one Disable object, and communication management module ComM manages mould to message Transmission/reception of the communication channel to message is closed in block Com request；When the communication request pair for thering is control to require the communication channel As there is no after Disable object, communication management module ComM can just request to open the communication channel to message management module Com Transmission/reception to message.

It can be seen that only do not hear the communication request of Lock object, can just respond the communication request of Local object with And the release to Local object, wherein the communication request for not hearing Lock object illustrates currently to have discharged the Lock object Communication request.And the communication request of Remote object does not need to discharge, and is determined by automotive networking administrative mechanism.

Processing priority analysis based on the communication request object above to each object type, the present embodiment are currently supervised After the object type for hearing multiple communication request objects, it can determine how communication management module ComM responds to multiple logical The communication request of letter request object, i.e., according to the processing priority of the communication request object of each object type from high to low suitable Sequence, the communication request of response respective communication request object.

Optionally, for the information configuration table in foregoing embodiments, communication request object can be generated in the following way Information configuration table, but be not limited to the present embodiment description this generating mode, as shown in figure 5, this method may include:

Step S21 obtains each communication request object under operating status with communication requirement；

Such as above-mentioned analysis, the object that the present embodiment can will cause communication channel to open or close is denoted as communication request Object specifically can be event caused by I/O equipment in Vehicle Control Network system, such as open ignition switch, or by network The condition that state determines, such as certain network node send network management message.

Optionally, the present embodiment can be analyzed by the requirement description file to client, be obtained existing for current ECU All communication request objects with communication requirement, concrete methods of realizing is without limitation.Under normal conditions, acquisition has communication The quantity of the communication request object of demand is multiple.

Step S22 distributes one-to-one object ID for each communication request object；

In practical applications, a communication request object can control multiple communication channels, and many communication requests simultaneously It is independent from each other between object, will appear some time interior one communication channel of multiple communication request object controls, just for area Divide each communication request object, the present embodiment can distribute unique object ID for each communication request object.

It is to be appreciated that the present embodiment to the content of above-mentioned object ID without limitation, can be continuously numbered for or character etc. Deng being illustrated so that object ID is number since 0 as an example herein, i.e., 0,1,2 ... are sequentially allocated to multiple communications of acquisition Request object.

Step S23, according to the communication feature of each communication request object, determine the communication request object object type and Communication attributes；

In the present embodiment, the communication feature of each communication request object can be predefined, specifically can be according to current scene Lower real work demand determines, such as power supply high pressure or low voltage failure, it is desirable that communication close；Bus error failure, it is desirable that forbid reporting Text sends and executes fault recovery；Ignition switch is opened, it is desirable that opens local communication etc., the present embodiment no longer arranges one by one herein It lifts.

It as an alternate embodiment of the present invention, is referred to mode shown in fig. 6 and realizes above-mentioned steps S14, such as Fig. 6 institute Show, can specifically include but be not limited to following steps:

Step S31 determines the requested communication channel of communication request object；

Such as above-mentioned analysis, the communication channel in ECU has multiple, and different communication requests object can be according to respective communication special Point, for corresponding communication channel initiate communication request, and each communication request object initiate communication request can be it is independent, because This may receive the communication request of multiple communication request objects for each communication channel whithin a period of time, For this communication channel, the present embodiment can be handled according to preset object priority weighing mechanism, specific processing side The rapid description content of formula following steps, however, it is not limited to this.

Step S32 detects whether that there are the communication requests of Lock object, if so, entering step S33；If not, executing Step S34；

In conjunction with the description content above for object priority weighing mechanism, the present embodiment is according to all types of communication requests The sequence of the processing priority of object from high to low, communication of the response for multiple communication request objects of the same communication channel Request.Therefore, the present embodiment can first detect whether have Lock object in the communication request object for the communication channel, i.e., The highest object type of processing priority such as exists, by the communication request of priority processing Lock object；It if it does not exist, will be according to The sequence of processing priority from high to low, is successively detected.

Specifically, as above-described embodiment analysis, the present invention can by query information allocation list, obtain listen to it is each The object type of communication request object, later, directly at least one object type corresponding to different communication channel of acquisition It is detected, to determine the communication request object that whether there is this object type of Lock object for each communication channel.

Step S33, the communication attributes according to Lock object handle the communication channel；

In the present embodiment, which is the above-described process content to Lock object, that is, closes the communication Channel, specifically according to the communication attributes content of preset Lock object, to close the communication channel, i.e., according to the Lock object Communication attributes content inputs corresponding high/low signal to each communication channel, to close the communication channel.

Optionally, in the present embodiment practical application, determine that the communication request for the communication channel includes Lock object Communication request, i.e., to the communication channel have communication requirement communication request object include Lock object, as shown in Figure 7a, this Embodiment can first detect whether the last communication request object for the communication channel includes Lock object, if comprising, The so last communication request for necessarily having responded to the Lock object, that is, be turned off the communication channel, do not need at this time again Secondary closing can directly terminate process；Conversely, executing step S33 again, that is, close the communication channel.It specifically can be by communication tube It manages module ComM and is based on the testing result, request network management integration module NmIn closes the communication channel.

It can be seen that determining to include Lock pairs in the communication request object for the communication channel in above-mentioned steps S32 As rear, as shown in Figure 7a, the present embodiment can first detect the last communication request object for the communication channel whether include Lock object, if so, terminating this process flow；If not, the communication is closed in request according to the communication attributes of Lock object Channel.

Step S34 detects whether that there are the communication requests of Local object, if so, entering step S35；If not, holding Row step S36；

Determine that the communication channel there is no in the case where Lock object, further detects at least one obtained communication request Whether the object type of object is Local type, if so, system asks the communication that first response belongs to the Local object type Seek the communication request of object；Conversely, in the presence of further detecting whether a priority object type communication request object.

Step S35, the communication attributes according to Local object handle the communication channel；

Similar with the processing of above-mentioned steps S33, the present embodiment is determining that there are Local objects (Lock object is not present In the case where), by according to the communication attributes of the Local object prestored, belong at least one communication request pair of the object type The communication request of elephant is handled, specifically, input meets the control signal of the communication attributes, will open the sheet of the communication channel Ground communication function.

Optionally, the trigger condition and executive mode of step S35, trigger condition and the side of execution with above step S33 Formula is similar, is specifically referred to flow diagram shown in Fig. 7 b, determines the communication request for the communication channel by step S34 Lock object is not present in object, but there are Local object, and the present embodiment can detecte the last communication for being directed to the communication channel Request whether object includes Local object, if so, it is considered that the local communication function of the current communication channel has been opened It opens, can directly terminate the process, if not, can request to open the communication channel according to the communication attributes of Local object Local communication mode.

Step S36 detects whether that there are the communication requests of Remote object, if so, entering step S37；If not, holding Row step S38；

The present embodiment is determining that currently there is no Lock object and Local pairs for the communication request object of the communication channel As in the case where, system can just control the communication request of the communication request object of communication channel response Remote type；Conversely, The present embodiment will be handled according to above-described object priority authority mechanism.

Step S37, the communication attributes according to Remote object handle the communication channel；

Referring to the description to step S33 and step S35 above, the present embodiment determines the communication request for being directed to the communication channel Lock object and Local object is not present in object, but there are Remote object, the communication request for executing the Remote object it Before, as shown in Figure 7 c, can first detect the last communication request object for the communication channel whether there is Remote object, If it does, process can be terminated, if it does not, the communication is opened in request according still further to the communication attributes of the Remote object The remote communication mode in channel.

Step S38 is inquired in the last communication request object for the communication channel listened to the presence or absence of Local Object, if it does not, terminating process, if it does, entering step S39.

The communication channel local communication mode is closed in step S39, request.
