Description
Technical field
The present invention relates to communication technical field, the communication means particularly between a kind of vehicle and system, server for inter-vehicular communication.
Background technology
Along with popularizing of vehicle, self-driving travel of forming a team becomes a kind of popular mode of going on a tour gradually.In the process of forming a team self-driving travel, the vehicle condition that each car faces and road conditions different, and the driving technology of each car driver is also not quite similar, and the position in same fleet between each vehicle is mostly different.Usually, a determining deviation is kept between each car, the distance that whole fleet stretches is also long, in order to keep the integrality of fleet (not allowing the vehicle in fleet occur the situation of falling behind) and safety, generally by one or several cars keeper's (such as can using head car and the trailer keeper as fleet) as whole fleet in driving conditions, by in time assigning instruction to other vehicles, control direction of traffic and the road speed of vehicle, make whole fleet keep complete formation to advance; On the other hand, other vehicles need current driving conditions and vehicle location immediately to carry out feeding back or active reporting to keeper too, are convenient to keeper can make reply in time plan according to emergency case.For this reason, the real time communication realized in fleet between vehicle is needed.
At present, the common implementation of the real time communication in fleet between vehicle comprises employing traditional intercom call, mobile phone/car phone call etc.Connect although these existing implementations can set up call, all there is respective problem.Such as, tradition intercom (such as hand platform or vehicle radio station) is passed through in the frequency of setting with the mode transferring voice of wireless signal, due to the finiteness of frequency resource, therefore easily there is the situation of interference, and when being conversed by intercom, speech quality is often subject to the restriction of both call sides distance, when occurring that emergency case causes spaces of vehicles to increase, likely can exceed call allowed band and cannot connect.Again such as, employing mobile phone/car phone is conversed, drive while hold mobile phone/car phone and carry out call and can make driver distraction and then affect traffic safety, although rely on the hand-free function of mobile phone/car phone can guarantee traffic safety to a certain extent, the call cost that mobile phone/car phone is higher is also cause it can not one of the major obstacle of extensive use.
Along with the development of the communication technology, especially the extensive use of digital mobile communication technology, in fleet's trip (self-driving travel of such as forming a team) process, the mode of employing digital handset realizes the real time communication in fleet between vehicle, due to the utilance of frequency spectrum resource can be improved, improve voice call quality, improve and improve voice-and-data integrated, the signal changing the transmission of traditional intercom increases and the weakness of reduction with communication distance, is therefore the inexorable trend of following intercom technical development.The specific implementation process of digital handset is roughly: when the digital handset of vehicle is in unlatching, if vehicle (driver or car other passengers interior) is for initiating call (or abbreviation is made a speech), call function can be started, the voice messaging gathered is passed through 2G/3G (SecondGeneration/ThirdGeneration with the form of digital signal, the second generation/third generation) cordless communication network send to server, by described server, the described voice messaging received is sent to the digital handset of target vehicle again, described target vehicle refers to the conversation object specified by vehicle of initiating call, it can be the call that a car is initiated to another car, also can be the call that a car is initiated to many cars, the latter initiates call to the vehicle belonged in same group.After target vehicle receives described voice messaging, by the digital handset in vehicle, voice are broadcasted.Certainly, no matter be traditional intercom or digital handset, generally all cannot realize multi-party simultaneous talking, must wait for the voice of a side broadcast terminate after could start the voice broadcasting of the opposing party.
But, fleet is in traveling process, except keeper assigns except 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 the content now broadcast is not high or policy-making not strong, but because the broadcasting existence of voice messaging first receives the feature first broadcast, and fleet normally remains on transport condition, this will cause keeper can not make instruction in time according to emergency case, namely can not guarantee that the speech of keeper is broadcast to control better whole fleet in time and kept complete formation to advance.
The correlation technique of inter-vehicular communication can be also the Chinese patent application of CN101313491A with reference to publication number, the patent application discloses the various technology of the passenger in permission one vehicle and the passenger traffic in another vehicle.

Embodiment
Prior art is difficult to guarantee that the voice messaging that the keeper in fleet sends is broadcast in time.The technical program is by the talkback unit pre-set priority to vehicle, when communicating between vehicle, after the voice messaging that the talkback unit receiving vehicle sends, identify the priority that the talkback unit of each transmission voice messaging is corresponding, the voice messaging that sent by each talkback unit of height according to priority sorts waiting to broadcast in queue again, wait to broadcast putting in order of voice messaging in queue based on described, successively voice messaging is broadcast the talkback unit to target vehicle, thus the voice messaging that the talkback unit (talkback unit of the keeper place vehicle in such as fleet) can guaranteeing to have high priority sends can preferentially be broadcast.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
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 to implement with multiple, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention.Therefore the present invention is not by 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, the voice messaging that the talkback unit receiving vehicle sends;
Step S102, identifies the priority that the talkback unit of each transmission voice messaging is corresponding;
Step S103, according to priority the voice messaging that each talkback unit sends is placed in and waits to broadcast among queue by order from high to low;
Step S104, waits to broadcast putting in order of voice messaging in queue based on described, successively voice messaging is broadcast the talkback unit to target vehicle.
With specific embodiment, the communication means between above-mentioned vehicle is elaborated below.
In the present embodiment, for the communication between many automobiles of fleet whole in self-driving travel of forming a team, each automobile is provided with talkback unit, described talkback unit is integrated among mobile unit, be specifically as follows digital handset, also can for realizing the software module (digital handset of software implementation can be thought) of intercom function, it relies on vehicle-mounted radio communication terminal to realize the call of user between vehicle, and various information is all carry out transmitting with the form of digital signal.
In addition, the present embodiment, in order to realize the communication between vehicle, except talkback unit set on vehicle, also needs to have server.As described in the background art, when the digital handset of vehicle is in unlatching, after call (speech) initiated by vehicle (driver or car other passengers interior), generally the voice messaging of collection can be sent to server with the form of digital signal by the cordless communication network of 2G/3G, then by described server, the described voice messaging received be sent to target vehicle.No matter be traditional intercom or digital handset, generally all cannot realize multi-party simultaneous talking, must wait for the voice of a side broadcast terminate after could start the voice broadcasting of the opposing party.But, because fleet is in traveling process, except the keeper of fleet assigns except instruction to other vehicles, other vehicles also can broadcast voice messaging by server to other vehicle at any time, the general importance of the content now broadcast is not high or policy-making not strong, such as to impression, the brief chatting and laughing etc. of around landscape, but because the broadcasting of voice messaging exists the feature first receiving and first broadcast usually, this can cause keeper can not make instruction in time according to emergency case, namely can not guarantee that the speech of keeper is broadcast in time.
In order to guarantee that the speech of keeper can preferentially be broadcast, inventor considers, if carry out priority setting by the speaking party of the voice messaging treating broadcasting, determine the transmission sequence of its voice messaging sent with the height of the priority of speaking party, so just preferentially can broadcast the voice messaging of some outbalances.Because voice messaging is sent by the talkback unit of vehicle, therefore the priority of speaking party corresponds to again the priority of talkback unit.Therefore, what distinguish to some extent with server of the prior art is, the voice messaging that server described in the present embodiment sends except the talkback unit of usual had reception vehicle and send except voice messaging to the effect of the talkback unit of target vehicle, also for accepting the setting of the priority of the talkback unit for vehicle, and based on vehicle talkback unit corresponding to the transmission sequence of priority determination voice messaging.
Form a team self-driving travel time, after composition fleet, the keeper of fleet should be pre-determined, described keeper can have several, generally can be decided to be keeper by two cars (head car and trailer) that is fleet is first, fleet's tail, the speed that head car guides fleet to advance and direction, trailer guarantees that the vehicle in the middle of fleet is held up, certainly, in fleet, also can increase other keeper.The predeterminable higher priority (being generally the highest priority) of the talkback unit of vehicle residing for all keepers, set priority can be identical, also can not be identical, namely also has dividing of rank in keeper; The talkback unit of other vehicles then presets lower priority, and set priority can be identical, also can not be identical, and the talkback unit of the vehicle of namely following in fleet also can have dividing of rank.Therefore, before communicating between the vehicle in fleet, the priority of the talkback unit pre-setting each vehicle is needed.Such as, 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 vehicle residing for keeper is set to the first priority, the priority of the talkback unit of more rich for some driving experiences user institute steering vehicle is set to the second priority, the priority of the talkback unit of user less for some driving experiences institute steering vehicle is set to the 3rd priority.Certainly, the above-mentioned setting for priority is only simply give an example, generally the keeper in fleet can be set to the highest priority, can guarantee that the voice messaging that keeper sends preferentially is broadcast like this, thus enable keeper assign instruction to other vehicles in fleet in time, control direction of traffic and the road speed of vehicle, make whole fleet keep complete formation to advance.Certainly, in other embodiments, can also according to the more multi-level priority of the dissimilar setting of driver or passenger, even the priority of the talkback unit of certain car or a few cars can be arranged higher than the talkback unit of the vehicle residing for keeper.Such as: when having vehicle that leader takes in a fleet, escort vehicle, when escorting vehicle etc. that the manager of vehicle takes, the keeper that the manager escorting vehicle advances as whole fleet, there is higher priority, although 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 keeper, generally can be set to the highest priority.
It should be noted that, in the present embodiment, above-mentioned priority is with corresponding to the talkback unit of vehicle, when described talkback unit is the software module realizing intercom function, the priority of talkback unit is specifically bound with the user account logging in described talkback unit, and have nothing to do with concrete vehicle, as long as namely preset the priority that the user account of keeper is corresponding, then no matter which car it has driven, and the priority of the talkback unit of this car is exactly the priority that keeper has.After the priority level initializing of the talkback unit of vehicles all in fleet, priority setting information is sent to server, after described priority setting information is preserved by described server, when communicating between subsequent vehicle, just can based on the transmission sequence of the priority determination voice messaging of each talkback unit of transmission voice messaging.
When communicating between vehicle, first perform step S101, the voice messaging that the talkback unit receiving vehicle sends.Particularly, when the user (driver or car in other passengers) of certain car thinks speech, then can start call function (such as pressing " speech button "), namely the sound-recording function (recording device of mobile unit can be coordinated) of described talkback unit is opened, then think word under record, then by talkback unit, voice messaging lower for record is sent to server (instruction of transmission voice messaging triggers by the button bleeding off " 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 mobile unit, and described mobile unit has the terminal equipment that can realize radio communication, and the mobile communication of 2G/3G can be adopted to communicate with server.
After the voice messaging that the talkback unit that described server receives vehicle sends, perform step S102, identify the priority that the talkback unit of each transmission voice messaging is corresponding.Particularly, the talkback unit of vehicle is while transmission voice messaging, the general information all enclosing transmit leg (speaking party), in the present embodiment, the information of the transmit leg enclosed is the user account (No. ID) of foregoing login talkback unit, certainly this user account each car talkback unit can the pet name form show.Therefore, identify that namely the priority that the talkback unit of each transmission voice messaging is corresponding identify and the user account that sent voice messaging is bound.Such as: suppose there are A, B, C tri-cars, wherein the driver of A is keeper, has the first priority, its user account logging in talkback unit is ID001; B is the more rich driver of driving experience, has the second priority, and its user account logging in talkback unit is ID002; C is the less driver of driving experience, and have the 3rd priority, its user account logging in talkback unit is ID003.Be ID001 when described server identifies the user account bound with the voice messaging received, then can determine based on the priority setting information prestored that the priority of this user account (talkback unit) is the first priority.In like manner, if identifying the user account bound with the voice messaging received is ID002 or ID003, then can determine that the priority of this user account (talkback unit) is the second priority or the 3rd priority respectively.
After identifying priority corresponding to the talkback unit of each transmission voice messaging, perform step S103, according to priority the voice messaging that each talkback unit sends is placed in and waits to broadcast among queue by order from high to low.In prior art, be generally the voice messaging first received first is carried out broadcast, namely embody the principle first receiving and first broadcast.And the present embodiment, specifically by the priority order from high to low that described talkback unit is corresponding, the voice messaging that each talkback unit sends is placed in and waits to broadcast among queue.Such as: suppose in a certain shorter time period, successively there is B, C, the talkback unit of A tri-cars 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 sends is placed in and waits to broadcast (before supposing, this queue is without voice messaging to be broadcast) first of queue, the voice messaging that the talkback unit of B car sends is placed in thereafter (after the voice messaging of the talkback unit transmission of A car), after the voice messaging that the talkback unit voice messaging that the talkback unit of C car sends being placed in B car sends.Can comparatively visually by now wait broadcast queue be expressed as: A-B-C.If now there is again 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, when A, B, C tri-car talkback unit send voice messaging all do not broadcast, after then the voice messaging that the talkback unit of D car sends being placed in B car, before C car, can comparatively visually by now wait broadcast queue be expressed as: A-B-D-C.Therefore, as long as the talkback unit sending voice messaging has higher priority, can ensure that its voice messaging sent is in all the time and wait to broadcast the position before queue comparatively, namely can preferentially be broadcast.Certainly, can know from citing above, if the priority that the talkback unit identifying the vehicle of more than is corresponding is identical, then still determine that described voice messaging is waited to broadcast putting in order of queue described in being placed in the sequencing receiving voice messaging, although namely the talkback unit of D car has identical priority with the talkback unit of B car, but the time of the voice messaging that the time of the voice messaging that the talkback unit that server receives B car sends sends than the talkback unit receiving D car is more Zao, so waiting to broadcast in queue, the voice messaging that the talkback unit of B car sends is front, the voice messaging that the talkback unit of D car sends is rear.Thus, the sequence to the voice messaging that each talkback unit sends is achieved by step S103.In reality is implemented, described sequence of waiting to broadcast voice messaging in queue is in the state of continuous renewal, namely server is once receive new voice messaging, just can determine that it broadcasts the sequence in queue described waiting according to the priority of the talkback unit sending this voice messaging, the forward voice messaging that sorts can preferentially be broadcast.
After being sorted by the voice messaging of reception, perform step S104, wait to broadcast putting in order of voice messaging in queue based on described, successively voice messaging is broadcast the talkback unit to target vehicle.Particularly, based on step S103 to after the sequence of the voice messaging that each talkback unit sends, wait to broadcast putting in order of voice messaging in queue according to what formed, successively voice messaging is broadcast the talkback unit to target vehicle.Such as, still be described with previous example, formed such as " A-B-D-C " wait broadcast after queue, the voice messaging that first talkback unit of A car sends by server broadcasts the talkback unit to target vehicle, and the voice messaging then sent by the talkback unit of B, D, C tri-cars successively broadcasts the talkback unit to target vehicle.Described target vehicle refers to the conversation object specified by vehicle of initiating call, it can be the call (may be defined as private chat pattern) that a car is initiated to another car, also can be the call (may be defined as group chat pattern) that a car is initiated to many cars, the latter initiates call to the vehicle belonged in same group, such as, in the present embodiment, all vehicles in the fleet that self-driving travel of forming a team can be formed are set to same group.Certainly, an above-mentioned vehicle is realized to the call of another vehicle or many car initiations by described talkback unit and server, such as, user can select call mode by talkback unit in advance, when selecting private chat pattern, user clicks and specifies the user name of conversation object and send to server, and talkback unit ejects interface prompt simultaneously and whether carries out private chat, after user verification, talkback unit display private chat modal window; When selecting group chat pattern, talkback unit display group chat modal window, the voice data that user sends by Server Default sends to all members of user place group.Therefore, in intercommunication application process, as long as user presses " speech button " just the voice data (passing through server) recorded can be sent to target vehicle.After target vehicle receives described voice messaging, voice are broadcasted (audio playing apparatus of mobile unit also can be coordinated to realize) by the audio playing function automatically can opening described talkback unit.In addition, it should be noted that, after server completes the broadcasting treating certain voice messaging broadcast in queue, this voice messaging can be deleted from waiting to broadcast queue, to enable to wait that broadcasting queue holds more voice messaging.
Pass through above-mentioned steps, just can guarantee that the voice messaging that the talkback unit with high priority sends can preferentially be broadcast, so, the voice messaging that the talkback unit of vehicle residing for the keeper in fleet sends can be broadcast in time, the talkback unit of other vehicle receives described voice messaging and after broadcasting, just can understand the instruction that keeper assigns.When reality is implemented, if keeper constantly makes a speech, then user's (talkback unit that priority is lower) that other priority are lower just has no chance to chip in, even if keeper's speech slightly pauses, other user is also difficult to " robbing wheat "; And in the lower user's constantly speech process of other priority, if keeper needs speech, then can interrupt the speech of the lower user of priority, realize the operation of " robbing wheat " of the keeper of fleet.
In addition, the communication means between described vehicle also comprises: when the described length wait broadcasting queue reaches predetermined threshold value, the talkback unit shielding all vehicles sends voice messaging.Generally consider server efficiency and play the instantaneity of voice, the amount of stored voice messaging can be controlled, namely the length broadcasting queue is waited described in controlling, particularly, can for waiting that the length broadcasting queue pre-sets a threshold value, described predetermined threshold value is define the critical value treating whether broadcasting queue has been booked, when the length until broadcasting queue of reality equals or exceeds this predetermined threshold value, just the voice messaging that the talkback unit no longer receiving vehicle sends, now make the talkback unit of vehicle cannot send voice messaging (such as cannot press " speech button ") by sending a control information.Describedly wait that broadcasting the length of queue can be determined by total data volume of received voice messaging or total reproduction time.Such as, described predetermined threshold value can be set to the value (such as 1M, 2M, 5M etc.) of a certain data volume, when total data volume of received voice messaging equals or exceeds the control message that this predetermined threshold value then triggers the talkback unit transmission voice messaging shielding all vehicles; Also described predetermined threshold value can be set to the value (such as 1 minute, 2 minutes, 5 minutes etc.) of a certain reproduction time, then trigger when the reproduction time summation of received all voice messagings equals or exceeds this predetermined threshold value the control message that the talkback unit shielding all vehicles sends voice messaging.Certainly, wait described in that the length broadcasting queue can also by waiting that broadcasting the time receiving voice messaging in queue the earliest determines with the difference of the time receiving voice messaging the latest.Such as, if will wait that broadcasting the time receiving voice messaging in queue is the earliest designated as t1, to wait that broadcasting the time receiving voice messaging in queue is the latest designated as t2, then t2-t1 determine described in wait to broadcast the length of queue, if described predetermined threshold value is set to 20 seconds, namely the difference requiring to wait to broadcast in queue the earliest and the latest time of received voice messaging can not equal or exceed 20 seconds, if equal or exceed 20 seconds (t2-t1 >=20s), the talkback unit triggering all vehicles of shielding sends the control message of voice messaging, the talkback unit of vehicle is now no longer allowed to send voice messaging to server, can ensure that the voice messaging that the talkback unit of vehicle is play is all nearest speech like this, and the speech that can not exist for a long time is played again, ensure that the instantaneity of play voice messaging.
Based on the communication means between above-mentioned vehicle, embodiment of the present invention additionally provides a kind of server for inter-vehicular communication.Fig. 2 is the structural representation of the server for inter-vehicular communication that embodiment of the present invention provides, and can consult Fig. 2, and described server 10 comprises: receiving element 101, the voice messaging that the talkback unit being suitable for receiving vehicle sends; Recognition unit 102, is connected with described receiving element 101, is suitable for the priority identifying that the talkback unit of each transmission voice messaging is corresponding; Sequencing unit 103, is connected with described recognition unit 102, and the voice messaging that each talkback unit sends is placed in by the priority order from high to low that each talkback unit being suitable for identifying by described recognition unit 102 is corresponding to be waited to broadcast among queue; Broadcast unit 104, be connected with sequencing unit 103, be suitable for waiting to broadcast putting in order of voice messaging in queue based on described, successively by voice messaging broadcasting to the talkback unit of target vehicle.
Certainly, described recognition unit 102 is in identifying, if priority corresponding to the talkback unit identifying the vehicle of more than is identical, then described sequencing unit 103 determine to be placed in the sequencing receiving voice messaging described in wait to broadcast putting in order of queue.
