Description

Communication means between vehicle and system, be used for the server of inter-vehicular communication

Technical field

The present invention relates to communication technical field, particularly the communication means between a kind of vehicle and system, be used for the server of inter-vehicular communication.

Background technology

Along with popularizing of vehicle, the self-driving travel of forming a team becomes a kind of popular mode of going on a tour gradually.In the process of self-driving travel of forming a team, vehicle condition and road conditions that each car faces are different, and each car driver's driving technology also is not quite similar, and the position in the same fleet between each vehicle is mostly different.Usually, keep a determining deviation between each car, the distance that whole fleet stretches is also long, for the integrality that keeps fleet (situation that does not allow vehicle in the fleet occur falling behind) and safety, in the driving process generally by one or several cars as the keeper of whole fleet (for example can with a car and the trailer keeper as fleet), by in time assigning instruction to other vehicles, direction of traffic and the road speed of control vehicle make whole fleet keep complete formation to advance; On the other hand, other vehicles need current driving situation and vehicle location are immediately fed back or active reporting to the keeper too, are convenient to the plan that the keeper can in time make according to emergency case reply.For this reason, need to realize the real time communication between the vehicle in the fleet.

At present, the common implementation of the real time communication between the vehicle comprises the traditional intercom conversation of employing, mobile phone/car phone conversation etc. in the fleet.Connect although these existing implementations can be set up conversation, all have problem separately.For example, tradition intercom (for example hand platform or vehicle radio station) by on the frequency of setting with the mode transferring voice of wireless signal, because the finiteness of frequency resource, so there is easily situation about disturbing, and when conversing by intercom, speech quality often is subject to the restriction of both call sides distance, when emergency case occurring and cause spaces of vehicles to increase, might exceed the conversation allowed band and can't connect.Again for example, converse for adopting mobile phone/car phone, hold mobile phone/car phone converses and the driver is divert one's attention and then affect traffic safety while driving, although rely on the hand-free function of mobile phone/car phone can guarantee to a certain extent traffic safety, the conversation cost that mobile phone/car phone is higher also is to cause one of major obstacle that it can not extensive use.

Development along with the communication technology, especially the extensive use of digital mobile communication technology, in fleet's trip (self-driving travel of for example forming a team) process, adopt the mode of digital handset to realize the real time communication between the vehicle in the fleet, owing to can improve the utilance of frequency spectrum resource, improve voice call quality, raising and improvement voice-and-data are integrated, the signal that changes traditional intercom transmission increases the weakness that reduces with communication distance, is the inexorable trend of following intercom technical development therefore.The specific implementation process of digital handset is roughly: when the digital handset of vehicle is in the situation of unlatching, if vehicle (other passengers in driver or the car) wish is initiated conversation (or being called for short speech), can start call function, the voice messaging that gathers is passed through 2G/3G (Second Generation/Third Generation with the form of digital signal, the second generation/third generation) cordless communication network sends to server, the described voice messaging that will be received by described server again sends to the digital handset of target vehicle, described target vehicle refers to the specified conversation object of vehicle of initiating to converse, it can be the conversation that a car is initiated to another car, also can be the conversation that a car is initiated to many cars, the latter initiates conversation to the vehicle that belongs in the same group.After target vehicle receives described voice messaging, by the digital handset in the vehicle voice are broadcasted.Certainly, no matter be traditional intercom or digital handset, general all can't realize multi-party simultaneous talking, must wait for that the voice broadcasting that finishes could begin afterwards the opposing party broadcast in a side voice.

Yet, fleet is in traveling process, except the keeper assigns the instruction to other vehicles, other vehicles also can make a speech to broadcast voice messaging to other vehicle at any time, the general importance of content that broadcast this moment is not high or policy-making not strong, but because existing, the broadcasting of voice messaging receives first the characteristics of broadcasting first, and fleet normally remains on transport condition, this will cause the keeper in time not make indication according to emergency case, can not guarantee that namely keeper's speech is kept complete formation to advance by in time broadcasting to control better whole fleet.

The correlation technique of inter-vehicular communication can be the Chinese patent application of CN 101313491A with reference to publication number also, this Patent Application Publication the various technology that allow the interior passenger of passenger and another vehicle in the vehicle to communicate by letter.

Embodiment

Prior art is difficult to guarantee that the voice messaging that the keeper in the fleet sends is in time broadcast.The technical program is in the situation of the urgent speech of needs, during urgent speaking request by sending when the talkback unit that receives vehicle, close down the voice messaging in the formation to be broadcast, and reception sends the emergency speech information of the talkback unit transmission of described urgent speaking request, again described emergency speech information is broadcast the talkback unit to target vehicle, in time broadcast thereby can guarantee to send the emergency speech information that the talkback unit of the vehicle of described urgent speaking request sends.

For above-mentioned purpose of the present invention, feature and advantage can more be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.

Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization in the situation of intension of the present invention.Therefore the present invention is not subjected to the restriction of following public embodiment.

Fig. 1 is the schematic flow sheet of the communication means between the vehicle that provides of embodiment of the present invention.As shown in Figure 1, the communication means between described vehicle comprises:

Step S101 when urgent speaking request that the talkback unit that receives vehicle sends, closes down the voice messaging in the formation to be broadcast;

Step S102 receive to send the emergency speech information that the talkback unit of described urgent speaking request sends, and described emergency speech information is broadcast talkback unit to target vehicle.

In specific embodiment, when described emergency speech information is preferentially broadcast to the talkback unit of target vehicle, can continue again to broadcast the voice messaging in the formation described to be broadcast, also can no longer broadcast the voice messaging in the formation described to be broadcast, namely after receiving described urgent speaking request, just delete the voice messaging in the formation described to be broadcast.In addition, usually the talkback unit that is not any vehicle can both send described urgent speaking request and emergency speech information, in the specific embodiment, corresponding user role and the priority of each user role can be set the talkback unit of each vehicle, only have the user role that acquires a certain degree when priority just to have the authority of urgent speech (triggering described urgent speaking request).

Need to prove, in the embodiment of the present invention, for formation to be broadcast in voice messaging distinguish to some extent, the voice messaging that the talkback unit that sends described urgent speaking request is sent is called emergency speech information.

The below elaborates to the communication means between above-mentioned vehicle with specific embodiment.

Embodiment one

In the present embodiment, communication in the self-driving travel of forming a team between many automobiles of whole fleet is as example, each automobile is provided with talkback unit, described talkback unit is integrated among the mobile unit, be specifically as follows digital handset, also can be for realizing the software module (can think the digital handset of software implementation) of intercom function, it relies on vehicle-mounted radio communication terminal to realize the conversation of user between vehicle, and various information all are to transmit with the form of digital signal.

In addition, present embodiment except talkback unit set on the vehicle, also needs to have server in order to realize the communication between vehicle.As described in the background art, digital handset at vehicle is in the situation of unlatching, after vehicle (other passengers in driver or the car) is initiated conversation (speech), generally the voice messaging that gathers can be sent to server with the form of the digital signal cordless communication network by 2G/3G, the described voice messaging that will be received by described server again sends to target vehicle.No matter be traditional intercom or digital handset, general all can't realize multi-party simultaneous talking, must wait for that the voice broadcasting that finishes could begin afterwards the opposing party broadcast in a side voice.Yet, because fleet is in traveling process, except the keeper of fleet assigns the instruction to other vehicles, other vehicles also can be broadcast voice messaging by server to other vehicle at any time, the general importance of content that broadcast this moment is not high or policy-making not strong, such as to the impression of landscape on every side, brief chatting and laughing etc., but because the characteristics of broadcasting are first received first in the common existence of broadcasting of voice messaging, this can cause the keeper in time not make indication according to emergency case, can not guarantee that namely keeper's speech is in time broadcast.

For the speech that can guarantee the keeper can in time be broadcast, the inventor considers, if in the situation of the urgent speech of needs, talkback unit by vehicle sends a urgent speaking request to server, when described server receives described urgent speaking request, stop to treat the broadcasting of broadcasting the voice messaging in the formation, and reception sends the emergency speech information of the talkback unit transmission of described urgent speaking request, again described emergency speech information is broadcast the talkback unit to target vehicle, so just can be guaranteed to send the emergency speech information (for example keeper's of fleet urgent speech) that the talkback unit of the vehicle of described urgent speaking request sends and preferentially to be broadcast.Therefore, with server of the prior art is distinguished to some extent be, the voice messaging that server described in the present embodiment sends except the talkback unit of the common reception vehicle that has and send voice messaging to the effect of the talkback unit of target vehicle, also be used for receiving urgent speaking request and/or emergency speech information, stop to treat the broadcasting of broadcasting the voice messaging in the formation based on described urgent speaking request, and described emergency speech information is broadcast talkback unit to target vehicle.

When forming a team self-driving travel, after forming fleet, should pre-determine the keeper of fleet, described keeper can have several, generally can be decided to be the keeper by two cars (car and trailer) fleet is first, fleet's tail, speed and direction that car guiding fleet advances, trailer guarantees that the vehicle in the middle of the fleet holds up, certainly, in fleet, also can increase other keeper.Generally (do not need promptly to make a speech), communication between vehicle can be according to existing techniques in realizing, when being in an emergency, the situation of falling behind etc. appears such as road ahead temporary enclosed, the predetermined traffic route of Iterim Change, certain car, this moment, the keeper need to promptly make a speech, namely change current speech transmission sequence, described urgent speech is at first broadcast.

In the communication that realizes in the situation of the urgent speech of needs between vehicle, consult Fig. 1, execution in step S101 at first when urgent speaking request that the talkback unit that receives vehicle sends, closes down the voice messaging in the formation to be broadcast.Described urgent speaking request generally can be triggered by the talkback unit of keeper's vehicle of living in of fleet, certainly, present embodiment is not restricted the user's (talkback unit of this user vehicle of living in) who triggers described urgent speaking request, also can be triggered by the talkback unit of other users vehicle of living in the fleet, need to can trigger the talkback unit setting of vehicle the parts (also can be software module) of urgent speaking request.Particularly, can be in the situation that needs are promptly made a speech, start the urgency traffic function and (for example press " button of promptly making a speech ", get final product and generally only need press " common speech button "), can trigger urgent speaking request this moment, by talkback unit described urgent speaking request is sent to server, when server receives described urgent speaking request, just stops to treat the broadcasting of broadcasting voice messaging in the formation.And, after sending urgent speaking request (simultaneously or and then), namely open the sound-recording function (recording device that can cooperate mobile unit) of described talkback unit, then think word under the record, the emergency speech information under will being recorded by talkback unit again sends to server (instruction that sends described emergency speech information can trigger by the button that bleeds off " button of promptly making a speech " or press similar " transmission ") with the form of digital signal by cordless communication network.Certainly, in the specific implementation, server is after receiving described urgent speaking request, also can send a feedback information (shows and receives this urgent speaking request, prepare to receive the emergency speech information that this talkback unit sends) to described talkback unit, described talkback unit can just send to server with described emergency speech information after receiving described feedback information.In the present embodiment, described talkback unit is integrated in the mobile unit, and described mobile unit has the terminal equipment that can realize radio communication, can adopt the mobile communication of 2G/3G and server to communicate.

In the present embodiment, when described server received described urgent speaking request, the talkback unit that can also shield other vehicles sent voice messaging.When the keeper promptly makes a speech, even the talkback unit of other vehicles sends voice messaging to server, this voice messaging generally also can be placed in the formation to be broadcast, at least need by the time keeper's urgent speech just might to be broadcast after finishing, because the emergency speech information that the talkback unit of keeper's vehicle of living in sends can preferentially be broadcast, the urgent speech meeting that is the keeper is broadcast at first, if the keeper ceaselessly promptly makes a speech, then other users are difficult to have an opportunity make a speech, therefore, if keeper's urgent speech is longer, the voice messaging that then probably causes the talkback unit of other vehicles to send to server is difficult to be broadcast, namely allow to be broadcast, that also needs wait for a long time, broadcasts away more when the time comes to seem outdated.So the talkback unit of other vehicles sent voice messaging again and just seemed and have little significance that the talkback unit that shields other vehicles sends voice messaging and can save the communication resource, can also alleviate to a certain extent the burden of server this moment.Certainly, in other embodiments, the talkback unit that also can not shield other vehicles sends voice messaging.

After receiving described urgent speaking request, execution in step S102 then receives the emergency speech information that the talkback unit that sends described urgent speaking request sends, and described emergency speech information is broadcast talkback unit to target vehicle.As previously mentioned, after server receives the described urgent speaking request of talkback unit transmission, stopped treating the broadcasting of broadcasting voice messaging in the formation, this moment, server then further received the emergency speech information that described talkback unit (sending the talkback unit of described urgent speaking request) sends, and this emergency speech information priority that will receive broadcasts the talkback unit to target vehicle, can guarantee that like this keeper's urgent speech is at first broadcast away.Generally speaking, in case receiving described emergency speech information just can go out its broadcasting immediately, if urgent speaking request and emergency speech information that the follow-up talkback unit that does not receive keeper's vehicle of living in sends, just can receive the voice messaging that the talkback unit of other vehicles sends and broadcast other voice messagings of not broadcasting in the formation described to be broadcast.Yet, when reality is implemented, after described server receives described urgent speaking request, if certain keeper carries out in the promptly speech process, last the emergency speech information that yet may exist the keeper to send is not also broadcasted, and the rear situation that emergency speech information is received that this keeper sends then can place a rear voice messaging last voice messaging to broadcast afterwards this moment.In addition, equally after server receives described urgent speaking request, the user of other keepers or promptly speech also can promptly make a speech, if have many because of the urgent emergency speech information of making a speech and receiving, the time order and function that then receives according to each emergency speech information is by arranged sequentially to evening early, particularly, one buffer queue can be set, the emergency speech information that successively receives is all placed described buffer queue, after last emergency speech information is broadcast, from this buffer queue, transfer again next bar emergency speech information and broadcast.

In the present embodiment, server is after having broadcast all emergency speech information, if urgent speaking request and emergency speech information that the follow-up talkback unit that does not receive keeper's vehicle of living in sends, just can receive the voice messaging of the talkback unit transmission of other vehicles, and again broadcast other voice messagings of not broadcasting in the formation described to be broadcast, specifically the voice messaging in the formation described to be broadcast is broadcast successively the talkback unit to target vehicle.

Target vehicle described in the step S102 refers to the specified conversation object of vehicle of initiating to converse, it can be the conversation (may be defined as the private chat pattern) that a car is initiated to another car, it also can be the conversation that a car is initiated to many cars, the latter initiates conversation (may be defined as the group chat pattern) to the vehicle that belongs in the same group, for example, in the present embodiment, all vehicles in the fleet that the self-driving travel of forming a team can be formed are made as same group.Certainly, an above-mentioned vehicle is realized by described talkback unit and server to the conversation of another vehicle or many car initiations, such as, the user can select call mode by talkback unit in advance, when selecting the private chat pattern, the user clicks the user name of specifying the conversation object and sends to server, and talkback unit ejects simultaneously interface prompt and whether carries out private chat, after the user confirmed, talkback unit showed the private chat modal window; When selecting the group chat pattern, talkback unit shows the group chat modal window, and the voice data that Server Default sends the user sends to all members of user place group.Therefore, in the intercommunication application process, as long as pressing " common speech button " or " button of promptly making a speech ", the user voice data (passing through server) that records can be sent to target vehicle.After target vehicle received voice messaging or emergency speech information, the audio playing function that can automatically open described talkback unit broadcasted voice (also can cooperate the audio playing apparatus of mobile unit to realize).In addition, need to prove, when server finish treat the broadcasting of broadcasting certain the bar voice messaging in the formation or finish described buffer queue in after the broadcasting of certain bar emergency speech information, this voice messaging can be deleted maybe from formation to be broadcast this emergency speech information is deleted from described buffer queue, so that formation described to be broadcast or described buffer queue can hold more voice messaging or emergency speech information.

Pass through above-mentioned steps, just can guarantee to send the emergency speech information that the talkback unit of urgent speaking request sends can preferentially be broadcast, so, the voice messaging (this keeper's urgent speech) that the talkback unit of the keeper's vehicle of living in the fleet sends can be broadcast in time, the talkback unit of other vehicle just can be understood the indication that the keeper assigns after receiving described emergency speech information and broadcast.When reality was implemented, if the keeper constantly promptly makes a speech, then usually other users did not have the chance speech, and namely other user generally is difficult to realize " robbing wheat " (only other keepers maybe can promptly make a speech user); And in the constantly speech process of other users, if the keeper needs urgent speech, then can interrupt other users' speech, the operation of the keeper of realization fleet " robbing wheat ".

In addition, the communication means between described vehicle can also comprise: when the length of formation described to be broadcast reached predetermined threshold value, the talkback unit of shielding vehicle sent voice messaging.Generally consider the efficient of server and the instantaneity of the voice of playing, can control the amount of the voice messaging of storing, namely control the length of formation described to be broadcast, particularly, can set in advance for the length of formation to be broadcast a threshold value, described predetermined threshold value is to define the critical value whether formation to be broadcast has been booked, when the length of the formation to be broadcast of reality equals or exceeds this predetermined threshold value, just no longer receive the voice messaging of the talkback unit transmission of vehicle, can make by sending a control information talkback unit of vehicle can't send voice messaging (for example can't press " common speech button ") this moment.The length of formation described to be broadcast can be determined by total data volume of the voice messaging that receives or total reproduction time.For example, described predetermined threshold value can be made as the value (such as 1M, 2M, 5M etc.) of a certain data volume, when total data volume of the voice messaging that receives equals or exceeds the control message that talkback unit that this predetermined threshold value then triggers the shielding vehicle sends voice messaging; Also described predetermined threshold value can be made as the value (such as 1 minute, 2 minutes, 5 minutes etc.) of a certain reproduction time, when the reproduction time summation of all voice messagings that receive equals or exceeds the control message that talkback unit that this predetermined threshold value then triggers the shielding vehicle sends voice messaging.Certainly, the length of formation described to be broadcast can also be determined with the difference of the time that receives the latest voice messaging by receiving the earliest the time of voice messaging in the formation to be broadcast.For example, be designated as t1 if receive the earliest the time of voice messaging in will formation be broadcast, the time that receives the latest voice messaging in the formation to be broadcast is designated as t2, then t2-t1 determines the length of formation described to be broadcast, if described predetermined threshold value is made as 20 seconds, namely require in the formation to be broadcast the earliest and the latest the difference of the time of received voice messaging can not equal or exceed 20 seconds, (talkback unit that t2-t1 〉=20s) then triggers the shielding vehicle sends the control message of voice messaging if equal or exceed 20 seconds, no longer allow the talkback unit of all vehicles to send voice messaging to server this moment, can guarantee that like this voice messaging that the talkback unit of vehicle is play all is nearest speech, and can not exist speech for a long time played again, guaranteed the instantaneity of the voice messaging of playing.

Need to prove, although when the length of formation described to be broadcast reaches predetermined threshold value, the talkback unit that shields other vehicles sends voice messaging, but the talkback unit that does not but shield the user place vehicle that uses urgent competence of speech sends urgent speaking request and emergency speech information.After receiving described urgent speaking request, even the length in formation to be broadcast has reached in the situation of predetermined threshold value, still can receive the emergency speech information that the talkback unit that sends described urgent speaking request sends, and described emergency speech information priority is broadcast talkback unit to target vehicle.When the length of formation described to be broadcast reached predetermined threshold value, the talkback unit of shielding vehicle sent voice messaging, and this is not only applicable to need inter-vehicular communication in the urgent speech situation, and is applicable to generally inter-vehicular communication; And foregoing server is when receiving described urgent speaking request, and the talkback unit that shields other vehicles sends voice messaging, and this need to be only applicable to the inter-vehicular communication in the urgent speech situation.In the specific implementation, can adopt simultaneously above-mentioned two kinds of talkback units to vehicle to send the mode that voice messaging shields.

Based on the communication means between the described vehicle of present embodiment, present embodiment also provides a kind of server for inter-vehicular communication.Fig. 2 is the structural representation of the server that is used for inter-vehicular communication that provides of the embodiment of the invention one, can consult Fig. 2, described server 10 comprises: receiving element 101, be suitable for receiving voice messaging and/or urgent speaking request that the talkback unit of vehicle sends, and after receiving described urgent speaking request, receive the emergency speech information of the talkback unit transmission that sends described urgent speaking request; First broadcasts unit 102, link to each other with described receiving element 101, be suitable for will formation 100 be broadcast (as shown in Figure 2, comprising voice messaging 1, voice messaging 2, voice messaging 3...... voice messaging n in the formation 100 to be broadcast) voice messaging broadcast successively talkback unit to target vehicle; Control unit 103, broadcasting unit 102 with described receiving element 101, first links to each other, be suitable for when described receiving element 101 receives the urgent speaking request that the talkback unit of vehicle sends, control described first and broadcast unit 102 and close down voice messaging in the formation 100 described to be broadcast; Second broadcasts unit 104, links to each other with described receiving element 101, is suitable for the emergency speech information that described receiving element 101 receives is broadcast talkback unit to target vehicle.

In the present embodiment, described server 10 also comprises the first screen unit 105, links to each other with described receiving element 101, is suitable for when receiving described urgent speaking request, and the talkback unit that shields other vehicles sends voice messaging.In addition, described server 10 also comprises secondary shielding unit 106, is suitable for when the length of formation 100 described to be broadcast reaches predetermined threshold value, and the talkback unit of shielding vehicle sends voice messaging.Particularly, the length of formation 100 described to be broadcast can be determined by total data volume of the voice messaging that receives or total reproduction time, also can determine with the difference of the time that receives the latest voice messaging by receiving the earliest the time of voice messaging in the formation 100 to be broadcast.In the specific embodiment, described the first screen unit 105 and secondary shielding unit 106 can integrate.

In the present embodiment, described control unit 103 also be suitable for described second broadcast unit 104 and send described emergency speech information after, control described first and broadcast unit 102 voice messaging in the formation 100 described to be broadcast is broadcast talkback unit to target vehicle successively.

The implementation of the described server for inter-vehicular communication of present embodiment can with reference to the enforcement of the communication means between above-mentioned vehicle, not repeat them here.

Embodiment two

The difference of present embodiment and embodiment one mainly is, among the embodiment one, be not restricted for the user's (talkback unit of this user vehicle of living in) who triggers described urgent speaking request, can be triggered by the talkback unit of keeper's vehicle of living in of fleet, also can be triggered by the talkback unit of other users vehicle of living in the fleet, if so the talkback unit of each vehicle can both trigger described urgent speaking request, described urgent speaking request and emergency speech information that the talkback unit that then may cause server to receive a plurality of users vehicle of living in sends, wherein may there be the unimportant voice messaging of content, so just be difficult to guarantee that real important emergency speech information (for example emergency speech information of keeper's transmission) is in time broadcast, therefore need to the user type that trigger described urgent speaking request be managed.Employing manages the user who triggers described urgent speaking request the mode that user role arranges priority in the present embodiment.Particularly, the priority of user role corresponding to each talkback unit and each user role is set, described user role comprises the first user role; The user role that the talkback unit of the described urgent speaking request of described transmission is corresponding is the user role that first user role or priority are higher than described first user role.In the present embodiment, described first user role is specially the keeper of fleet, namely only has the keeper of fleet or user that priority is higher than the keeper could trigger described urgent speaking request and emergency speech information.

In addition, in the situation that does not need urgent speech, the transmission sequence of the voice messaging in the formation described to be broadcast is to carry out according to receiving first the mode of broadcasting first in the prior art, is difficult to so equally make the voice messaging of some outbalances preferentially to be broadcast; And in the present embodiment, owing to be provided with the priority of user role corresponding to the talkback unit of each vehicle, before receiving described urgent speaking request, voice messaging in the formation described to be broadcast is by from high to low tactic of the priority of user role corresponding to the talkback unit that sends voice messaging, thereby the voice messaging that talkback unit (for example talkback unit of the keeper place vehicle in the fleet) with high-priority users role is sent can preferentially be broadcast.Certainly, if it is identical to send the priority of user role corresponding to the talkback unit of voice messaging, then putting in order of voice messaging is to determine by the sequencing that receives voice messaging in the formation described to be broadcast.

For no matter the speech that can guarantee the keeper is can be by preferential the broadcasting (in the situation that does not need urgent speech or in the situation of the urgent speech of needs), the inventor considers, if the voice messaging by treating broadcasting or the speech side of emergency speech information carry out the priority setting, determine with the height of the priority of the side of speech its transmission voice messaging transmission sequence or noly can trigger described urgent speaking request and emergency speech information, so just can preferentially broadcast voice messaging or the emergency speech information of some outbalances.Because being the talkback unit by vehicle, voice messaging sends, the user of use talkback unit has user role separately, therefore the priority of speech side is again corresponding to the priority of user role corresponding to talkback unit, in other words corresponding to the priority of the talkback unit of the user's vehicle of living in certain user role.Therefore, with server of the prior art is distinguished to some extent be, the voice messaging that server described in the present embodiment sends except the talkback unit of the common reception vehicle that has and send voice messaging to the effect of the talkback unit of target vehicle, the whole effects (mainly being processing and the transmitting-receiving emergency speech information to urgent speaking request) that not only have server described in the embodiment one, but also be used for to accept setting for the priority of the talkback unit of vehicle, and determine the transmission sequence of voice messaging or noly can trigger described urgent speaking request and emergency speech information based on the priority of user role corresponding to the talkback unit of vehicle.

When forming a team self-driving travel, after forming fleet, should pre-determine the keeper of fleet, described keeper can have several, generally can be decided to be the keeper by two cars (car and trailer) fleet is first, fleet's tail, speed and direction that car guiding fleet advances, trailer guarantees that the vehicle in the middle of the fleet holds up, certainly, in fleet, also can increase other keeper.The predeterminable higher priority of the talkback unit of keeper's vehicle of living in (being generally the highest priority), the priority that sets can be identical, can be not identical yet, namely also arranged among the keeper dividing of rank; The talkback unit of other vehicles is default lower priority then, and the priority that sets can be identical, can be not identical yet, and the talkback unit of the vehicle of namely following in the fleet also can have dividing of rank.Therefore, before communicating between the vehicle in fleet, need to pre-set the priority of the talkback unit of each vehicle.For example, the priority of the talkback unit of vehicle can be divided into three grades, be respectively the first priority, the second priority, the 3rd priority, wherein, the priority of the talkback unit of the residing vehicle of keeper is made as the first priority, the priority of the talkback unit of the more rich user of some driving experiences institute steering vehicle is made as the second priority, and the priority of the talkback unit of the user institute steering vehicle that some driving experiences are less is made as the 3rd priority.Certainly, above-mentioned setting for priority only is simply to give an example, generally the keeper in the fleet can be made as the highest priority, can guarantee that like this voice messaging that the keeper sends is preferentially broadcast, thereby make the keeper can be in time other vehicles in the fleet assign instruction, direction of traffic and the road speed of control vehicle make whole fleet keep complete formation to advance.Certainly, in other embodiments, can also be according to the more multi-level priority of driver or passenger's dissimilar settings, even the priority of the talkback unit of certain car or a few cars can be arranged to such an extent that be higher than the talkback unit of the residing vehicle of keeper.Such as: when have vehicle that the leader takes in the fleet, escort vehicle, when escorting vehicle that the manager of vehicle takes etc., escort the keeper that the manager of vehicle advances as whole fleet, has higher priority, although the leader does not relate to the management that fleet advances, but it has highest decision-making power (such as determining destination, change travel route etc.), therefore, the talkback unit of leader's ride-on vehicles has the priority higher than the keeper, generally can be set to the highest priority.

Need to prove, above-mentioned priority is corresponding with the talkback unit of vehicle in the present embodiment, when described talkback unit is when realizing the software module of intercom function, the priority of talkback unit is specifically bound with the user account of the described talkback unit of login, and it is irrelevant with concrete vehicle, as long as namely preseted priority corresponding to keeper's user account, then no matter which car it drives, and the priority of the talkback unit of this car is exactly the priority that the keeper has.After the priority level initializing with the talkback unit of all vehicles in the fleet, the priority configuration information is sent to server, after described server is preserved described priority configuration information, when follow-up inter-vehicular communication, just can determine based on the priority of each talkback unit that sends voice messaging the transmission sequence of voice messaging.

When under not needing promptly speech situation, carrying out inter-vehicular communication, at first receive the voice messaging of the talkback unit transmission of vehicle.Particularly, as the user (other passengers in driver or the car) of certain car when wanting to make a speech, then can start call function (for example pressing " common speech button "), namely open the sound-recording function (recording device that can cooperate mobile unit) of described talkback unit, then record is lower thinks word, and the voice messaging under will being recorded by talkback unit again sends to server (instruction of transmission voice messaging can trigger by the button that bleeds off " common speech button " or press similar " transmission ") with the form of digital signal by cordless communication network.In the present embodiment, described talkback unit is integrated in the mobile unit, and described mobile unit has the terminal equipment that can realize radio communication, can adopt the mobile communication of 2G/3G and server to communicate.

After described server received the voice messaging that the talkback unit of vehicle sends, identification respectively sent the priority corresponding to talkback unit of voice messaging.Particularly, the talkback unit of vehicle is when sending voice messaging, generally all can enclose the information of transmit leg (speech side), in the present embodiment, the information of the transmit leg of enclosing is the user account (ID number) of foregoing login talkback unit, and this user account is showed in the form that the talkback unit of each car can the pet name certainly.Therefore, identify priority corresponding to talkback unit that respectively sends voice messaging and namely identify the user account of binding with the voice messaging that sends.For example: suppose that A is arranged, three cars of B, C, wherein the driver of A is the keeper, has the first priority, and its user account that logs in talkback unit is ID001; B is the more rich driver of driving experience, has the second priority, and its user account that logs in talkback unit is ID002; C is the less driver of driving experience, has the 3rd priority, and its user account that logs in talkback unit is ID003.The user account that identifies with the binding of the voice messaging that receives when described server is ID001, then can determine that the priority of this user account (talkback unit) is the first priority based on pre-stored priority configuration information.In like manner, be ID002 or ID003 if identify the user account of binding with the voice messaging that receives, can determine respectively that then the priority of this user account (talkback unit) is the second priority or the 3rd priority.

After identifying priority corresponding to the talkback unit that respectively sends voice messaging, according to priority from high to low order voice messaging that each talkback unit is sent places among the formation to be broadcast.In the prior art, generally be that the voice messaging that receives is first broadcast first, namely embody and receive first the principle of broadcasting first.And present embodiment, specifically by priority order from high to low corresponding to described talkback unit, the voice messaging that each talkback unit is sent places among the formation to be broadcast.For example: suppose in a certain short time period, B is successively arranged, C, the talkback unit of three cars of A sends voice messaging to server, priority corresponding to the talkback unit of three cars as previously mentioned, then server is after identifying the priority of talkback unit, the voice messaging that the talkback unit of A car is sent places (suppose that before this formation is without voice messaging to be broadcast) first of the formation to be broadcast, the voice messaging that the talkback unit of B car is sent places thereafter (after the voice messaging that the talkback unit of A car sends), and the voice messaging that the talkback unit of C car is sent places after the voice messaging that the talkback unit of B car sends.Can comparatively visually queue table to be broadcast at this moment be shown: A-B-C.If there is again this moment the talkback unit of a D car to send voice messaging to server, and priority corresponding to the talkback unit of D car is the second priority, in the situation that the voice messaging that the talkback unit of A, B, C three cars sends is not all broadcast, the voice messaging that then talkback unit of D car is sent places after the B car, before the C car, can comparatively visually queue table to be broadcast at this moment be shown: A-B-D-C.Therefore, have higher priority as long as send the talkback unit of voice messaging, can guarantee that the voice messaging of its transmission is in formation to be broadcast all the time than the position of front, namely can preferentially be broadcast.Certainly, can know for example from top, if it is identical to identify priority corresponding to the talkback unit of the vehicle more than, then still determine that with the sequencing that receives voice messaging described voice messaging places putting in order of formation described to be broadcast, although the talkback unit that is the D car has identical priority with the talkback unit of B car, but the time that server receives the voice messaging that the talkback unit of B car sends is more Zao than the time of the voice messaging that the talkback unit that receives the D car sends, so in formation to be broadcast, the voice messaging that the talkback unit of B car sends is front, and the voice messaging that the talkback unit of D car sends is rear.Thus, realized the ordering of voice messaging that each talkback unit is sent.In reality is implemented, the ordering of voice messaging is in the state of continuous renewal in the formation described to be broadcast, be that in a single day server receives new voice messaging, just can determine its ordering in formation described to be broadcast according to the priority of the talkback unit that sends this voice messaging, the forward voice messaging that sorts can preferentially be broadcast.

After the voice messaging that receives sorted, based on putting in order of voice messaging in the formation described to be broadcast, successively voice messaging is broadcast the talkback unit to target vehicle.Particularly, after the ordering of the voice messaging that each talkback unit is sent, according to putting in order of voice messaging in the formation to be broadcast that forms, successively voice messaging is broadcast the talkback unit to target vehicle.For example, still describe with previous example, after the formation to be broadcast of formation such as " A-B-D-C ", the voice messaging that server at first sends the talkback unit of A car is broadcast the talkback unit to target vehicle, and the voice messaging that then successively the talkback unit of B, D, three cars of C is sent is broadcast the talkback unit to target vehicle.Described target vehicle refers to the specified conversation object of vehicle of initiating to converse, it can be the conversation that a car is initiated to another car, it also can be the conversation that a car is initiated to many cars, the latter initiates conversation to the vehicle that belongs in the same group, for example, in the present embodiment, all vehicles in the fleet that the self-driving travel of forming a team can be formed are made as same group.Certainly, the conversation initiated to another vehicle or many cars of an above-mentioned vehicle realizes by described talkback unit and server.After target vehicle received described voice messaging, the audio playing function that can automatically open described talkback unit broadcasted voice (also can cooperate the audio playing apparatus of mobile unit to realize).In addition, need to prove, after server is finished the broadcasting for the treatment of certain the bar voice messaging in the broadcasting formation, this voice messaging can be deleted from formation to be broadcast, so that formation to be broadcast can be held more voice messaging.

Pass through above-mentioned steps, just can guarantee to have the voice messaging that the talkback unit of high priority sends can preferentially be broadcast, so, the voice messaging that the talkback unit of the keeper's vehicle of living in the fleet sends can be broadcast in time, the talkback unit of other vehicle just can be understood the indication that the keeper assigns after receiving described voice messaging and broadcast.When reality was implemented, if the keeper constantly makes a speech, the user that then other priority are lower (talkback unit that priority is lower) was just have no chance to chip in, even keeper's speech slightly has pause, other user also is difficult to " robbing wheat "; And in the lower constantly speech process of user of other priority, if the keeper needs speech, then can interrupt the low user's of priority speech, realize the keeper's of fleet the operation of " robbing wheat ".

And when carrying out inter-vehicular communication in the promptly speech situation of needs, owing to be provided with the priority of user role corresponding to each talkback unit and each user role, in the present embodiment, the keeper of fleet is described first user role, its priority that has can trigger described urgent speaking request and emergency speech information, and the leader's of fleet user role is the user role than described first user role (keeper) higher priority, naturally also can trigger described urgent speaking request and emergency speech information, and the priority of other users' user role all is lower than described first user role (keeper), does not therefore have the authority (talkback unit of this type of user role does not arrange " button of promptly making a speech ") that triggers described urgent speaking request and emergency speech information.So, in the present embodiment, by the mode of user role priority corresponding to talkback unit is set, guaranteed that the emergency speech information that the keeper of fleet or the user that priority is higher than the keeper send can preferentially be broadcast.

Need to prove, although by the mode of user role priority corresponding to talkback unit is set, in the time of can under not needing promptly speech situation, carrying out inter-vehicular communication, make the higher user of priority realize " robbing wheat " operation, but when the length of formation described to be broadcast reaches predetermined threshold value, even the talkback unit of user's vehicle of living in of high priority also can't send voice messaging, but present embodiment can be by triggering described urgent speaking request and emergency speech information, thereby realized that the emergency speech information that the user (keeper) of high priority sends is in time broadcast.

Based on the communication means between the described vehicle of present embodiment, present embodiment also provides a kind of server for inter-vehicular communication.Fig. 3 is the structural representation of the server that is used for inter-vehicular communication that provides of the embodiment of the invention two, can consult Fig. 3, described server 10 ' is except comprising that the 10 included receiving elements 101, first of server described in the embodiment one are broadcast unit 102, control unit 103, second is broadcast unit 104, the first screen unit 105, the secondary shielding unit 106, also comprise setting unit 107, link to each other with described receiving element 101, be suitable for arranging the priority of user role corresponding to each talkback unit and each user role, described user role comprises the first user role; The user role that the talkback unit of the described urgent speaking request of described transmission is corresponding is the first user role, or priority is higher than described first user role's user role.

In the present embodiment, the voice messaging in the formation 100 described to be broadcast is by from high to low tactic of the priority of user role corresponding to the talkback unit that sends voice messaging.If it is identical to send the priority of user role corresponding to the talkback unit of voice messaging, then putting in order of voice messaging is to determine by the sequencing that receives voice messaging in the formation 100 described to be broadcast.

Other implementations of the described server 10 ' for inter-vehicular communication of present embodiment can with reference to the implementation of server 10 described in the communication means between the described vehicle of present embodiment and the embodiment one, not repeat them here.

Embodiment three

The difference of present embodiment and embodiment one, embodiment two is, among embodiment one and the embodiment two, when described emergency speech information is preferentially broadcast to the talkback unit of target vehicle, still continue to broadcast the voice messaging in the formation described to be broadcast, namely after receiving urgent speaking request, server is not deleted the voice messaging in the formation to be broadcast, and in the present embodiment, when receiving urgent speaking request, voice messagings all in the formation to be broadcast will be deleted.

When specific embodiment, when described server receives described urgent speaking request, with all voice messagings in the deletion formation described to be broadcast.Because after general management person promptly makes a speech, voice messaging in the formation to be broadcast before urgent speech is just somewhat outdated, therefore voice messagings all in the formation described to be broadcast all can be deleted, can be vacateed like this memory space of formation to be broadcast in order to can hold the more voice messaging that the talkback unit of other vehicles sends.Certainly, in embodiment one or embodiment two, although still keep the voice messaging that receives in the before formation to be broadcast of urgent speaking request, promptly make a speech and broadcast away again after finishing Deng the keeper, but in actual conditions, if during the memory space inadequate of formation to be broadcast (length that mainly refers to formation to be broadcast surpasses predetermined threshold value), then can be with being in the voice messaging deletion of formation described to be broadcast, until formation to be broadcast can be held the voice messaging that newly receives.

But the enforcement of the communication means among other implementation reference examples one of the communication means between the described vehicle of present embodiment or the embodiment two between vehicle does not repeat them here.

Based on the communication means between the described vehicle of present embodiment, present embodiment also provides a kind of server for inter-vehicular communication.Fig. 4 is the structural representation of the server that is used for inter-vehicular communication that provides of the embodiment of the invention three, can consult Fig. 4, described server 10 " receiving element 101 except comprising that server described in the embodiment one 10 is included; first broadcasts unit 102; control unit 103; second broadcasts unit 104; the first screen unit 105; outside the secondary shielding unit 106, also can comprise the setting unit in the server 10 ' 107 described in the embodiment two, also comprise: delete cells 108, link to each other with described receiving element 101, be suitable for when described receiving element 101 receives described urgent speaking request, deleting all voice messagings in the formation 100 described to be broadcast.

Need to prove, with server 10 ' described in embodiment one described server 10 or the embodiment two is distinguished to some extent be, the described server 10 of present embodiment " control unit 103 that comprises and first broadcasts between the unit 104 and there is no annexation; because delete cells 108 is when described receiving element 101 receives described urgent speaking request; will delete all voice messagings in the formation 100 described to be broadcast; and also present embodiment has the first screen unit 105 equally; and described the first screen unit 105 is when receiving described urgent speaking request; can shield the talkback unit transmission voice messaging of other vehicles, therefore there is not voice messaging in the formation 100 described to be broadcast, thus follow-up described control unit 103 described second broadcast unit 104 and send described emergency speech information after, just can not go to control described first and broadcast unit 102 voice messaging in the formation 100 described to be broadcast is broadcast talkback unit to target vehicle successively.

The described server 10 for inter-vehicular communication of present embodiment " other implementations can with reference to the implementation of server 10 ' described in server 10 described in the communication means between the described vehicle of present embodiment and the embodiment one or the embodiment two, not repeat them here.
