It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In the description of this application and the claims that follow, the terms "first," "second," "third," etc. are used merely to distinguish between descriptions and should not be construed to indicate or imply relative importance.
Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.
Some terms of art to which this application pertains are described below.
The internet of vehicles (vehicle to everything, V2X) communication is a key technology of a future intelligent transportation system, and the compatibility of manual driving and automatic driving is realized by integrating a global positioning system navigation technology, a vehicle-to-vehicle communication technology, a wireless communication and remote sensing technology and the like. The vehicle type of the system is matched, and under the automatic driving mode, the optimal driving route of the road condition can be automatically selected through analysis of real-time traffic information, so that traffic jam is greatly relieved. In addition, through using on-vehicle sensor and camera system, can also perceive the surrounding environment, make rapid adjustment to realize "zero traffic accident". For example, if a pedestrian suddenly appears, it may automatically slow down to a safe speed or stop.
Road Side Unit (RSU), also called road side sensing device, road side base station, intelligent base station, including laser radar, video camera, millimeter wave radar, etc. The road side equipment supports access to wind direction/wind force detector, remote measuring road surface condition sensor, variable traffic sign board and other equipment. Based on the multisource sensor fusion sensing technology, the artificial intelligent edge computing technology and the like, the road side equipment can comprehensively and accurately acquire real-time dynamic information of road traffic participants, and the information is transmitted to surrounding vehicles by utilizing a V2X communication protocol.
An on-board unit (OBU), also known as an in-vehicle terminal, in-vehicle device, refers to a microwave device that communicates with a roadside unit using V2X communication technology, such as short range communication (dedicated short range communication, DSRC) technology. In V2X communication, the vehicle-mounted unit establishes a microwave communication link with road side equipment by adopting a V2X communication protocol, and vehicle identity recognition, electronic fee deduction and the like can be realized under the condition of no stopping during vehicle running. It should be noted that, in the embodiments of the present application, the OBU supporting V2X communication is simply referred to as V2X-OBU.
The Uu interface is the most important interface in wideband code division multiple access (wideband code division multiple access, WCDMA) systems, whose main functions are broadcast paging and handling of radio resource control (radio resource control, RRC) connections. A User Equipment (UE) may access the fixed network part of the WCDMA system through a Uu interface.
In general, in V2X communication, various data may be collected by using a vehicle-end sensing device (for example, at least one of a millimeter wave radar sensor, a lidar sensor, and a camera provided on a vehicle) mounted on the vehicle, and then an in-vehicle terminal on the vehicle may transmit the data to a road side device through a V2X communication protocol, and the road side device may broadcast the vehicle information to surrounding vehicles through the V2X communication protocol, so that other surrounding vehicles mounted with the in-vehicle terminal may receive the information based on the V2X communication protocol and perform V2V scene triggering according to the information.
However, in some cases, some vehicles may not support V2X communication, so that the vehicles cannot interact with the road side unit, and the surrounding vehicles cannot acquire information of the vehicles, or the vehicles cannot acquire information of the surrounding vehicles, so that V2V scene triggering cannot be performed.
For this reason, the embodiments of the present application make improvements on the basis of the conventional road side device, and use the server and the road side device as intermediate devices of the first vehicle-mounted terminal that transmits the vehicle information and the second vehicle-mounted terminal that receives the vehicle information. Specifically, the first vehicle-mounted terminal firstly sends vehicle information to the server, and after the server obtains vehicle information sent by at least one vehicle, a first message based on a first communication protocol is generated according to the vehicle information and sent; and then, the road side equipment receives the first message based on the first communication protocol, generates a second message conforming to the second communication protocol according to the first message, and transmits the second message based on the second communication protocol, so that a second vehicle-mounted terminal supporting the second communication protocol can analyze the second message and acquire the vehicle information of the first vehicle-mounted terminal. Therefore, for vehicles which do not support the V2X communication protocol, not only can the information of surrounding vehicles be obtained, but also the surrounding vehicles can be enabled to obtain the information of the vehicles, so that the scene triggering of V2V is realized.
The following embodiments are used to describe exemplary information interaction methods, devices, terminals, storage media and the like provided in the embodiments of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of an information interaction system according to an embodiment of the present application. As shown in fig. 1, the system includes a cloud server 01, an edge server 021, a roadside apparatus 022, a vehicle 031, a vehicle 032, and a vehicle 033.
The cloud server 01, also called a cloud computing server, a cloud host, is deployed in a backbone data center of the internet, manages all computing servers, shared storage, etc., and can provide computing, storage, online backup, broadband services, etc. For example, in V2X communication, the cloud server 01 may acquire traffic data in real time, analyze the traffic data, and then provide weather prediction for registered users, plan an optimal driving route, and provide comprehensive services such as safety precaution.
The edge server 021 is connected to the cloud server 01 and the road side equipment 022, respectively. Wherein, vehicle 031 and vehicle 032 are located within the coverage of edge server 021. The edge server 021 is a channel where the vehicle 031 and the vehicle 032 access the cloud server 01, and at the same time, becomes a channel where the vehicle 031 and the vehicle 032 communicate with the roadside apparatus 022. Because the edge server 021 can locally complete certain processing operations, the cloud server 01 is not required to be used, for example, the edge server 021 is used for completing analysis and encapsulation of the acquired vehicle information, so that the load of the cloud server 01 is reduced to a certain extent, and the response speed of the vehicle request is improved.
The road side equipment 022 comprises information acquisition equipment such as a laser radar, a video camera, a millimeter wave radar and the like, supports access to a remote measuring road surface condition sensor, a variable traffic sign board and the like, and can also communicate with the V2X-OBU in the coverage range of the road side equipment 022. The road side device 022 may upload all or part of the acquired information to the cloud server 01, or may transmit some messages issued by the cloud server 01 to the vehicle-mounted terminals in the coverage area. In addition, since the roadside apparatus 022 is connected to the edge server 021, a message can be transferred therebetween.
It should be noted that, the server referred to in the embodiments of the present application may be an edge server. Taking the example that the vehicle-mounted terminals of the vehicle 031 and the vehicle 032 do not support V2X communication, the vehicle-mounted terminals of the vehicle 031 and the vehicle 032 and the road side device 022 cannot transmit messages by adopting a V2X communication protocol. The vehicle terminals of the vehicle 031 and the vehicle 032 may firstly send the collected information of the speed, heading angle, position, etc. of the vehicle to the edge server 021 based on UU interface communication protocol, then the edge server 021 transmits the information to the road side device 022, and then the road side device 022 broadcasts the information by adopting V2X communication protocol, so that the vehicle 033 located in the coverage area of the road side device 022 can receive the information through V2X-OBU. Information interaction between vehicles supporting V2X communication and vehicles not supporting V2X communication is thus achieved.
In this embodiment of the present application, the in-vehicle terminal for transmitting the vehicle information is referred to as a first in-vehicle terminal, and the in-vehicle terminal for receiving the vehicle information is referred to as a second in-vehicle terminal. Aiming at the problem that at least one of the first vehicle-mounted terminal and the second vehicle-mounted terminal does not support V2X communication, the embodiment of the application provides an information interaction method, which comprises the following steps:
s1, receiving a first message transmitted by a server by road side equipment based on a first communication protocol; the first message is a message generated from at least one vehicle information corresponding to a first vehicle terminal in communication with the server.
S2, the road side equipment generates a second message conforming to a second communication protocol according to the first message, and transmits the second message based on the second communication protocol; the second message may be parsed by a second vehicle terminal.
And S3, the vehicle-mounted terminal receives a second message based on a second communication protocol.
S4, the vehicle-mounted terminal analyzes the second message and acquires vehicle information contained in the second message.
For the information interaction scene of the vehicle-mounted terminal which does not support V2X communication, the information interaction scene is specifically divided into the following steps:
in the first scenario, the first vehicle-mounted terminal transmitting the vehicle information does not support V2X communication, and the second vehicle-mounted terminal receiving the vehicle information supports V2X communication.
In the second scenario, the first vehicle-mounted terminal transmitting the vehicle information supports V2X communication, and the second vehicle-mounted terminal receiving the vehicle information does not support V2X communication.
Neither the first vehicle-mounted terminal transmitting the vehicle information nor the second vehicle-mounted terminal receiving the vehicle information support V2X communication in scenario three.
In order to more clearly describe the above S1-S4, an exemplary description will be respectively developed for the information interaction method provided in the embodiment of the present application around these three scenarios.
Scene one:
for the scenario that the first vehicle terminal for sending the vehicle information does not support V2X communication, and the second vehicle terminal for receiving the vehicle information supports V2X communication, since the conventional vehicle generally supports other communication functions, such as UU interface communication protocols, under the precondition that the vehicle setting is not improved, data collected by the vehicle can be sent to the server based on other communication protocols, the server forwards the information to the road side device, so that the road side device broadcasts the vehicle information to surrounding vehicles by adopting the V2X communication protocol, and the vehicles supporting V2X communication in the surrounding can receive the information and trigger the V2V scene according to the information.
Fig. 2 is a schematic flow chart of an information interaction method according to an embodiment of the present application. The information interaction method includes S201 to S208 described below. It should be noted that, fig. 2 is an example of two first vehicle-mounted terminals, which is not limited to the embodiment of the present application, and the number of the first vehicle-mounted terminals may be one or more, and may be determined according to actual use requirements.
S201, the server receives at least one piece of vehicle information. A vehicle information corresponds to a first vehicle terminal in communication with the server. The first vehicle terminal does not support V2X communication.
The first vehicle-mounted terminal can be provided with various information acquisition devices such as a millimeter wave radar sensor, a laser radar sensor, a camera and the like. During the travel of the first vehicle-mounted terminal, the first vehicle-mounted terminal can acquire various information about the vehicle through the information acquisition devices. Such as vehicle speed, heading angle, position, lamp status, antilock braking system operating conditions, brake pedal depression conditions, auxiliary braking system operating conditions, etc.
Optionally, each of the vehicle information comprises at least one vehicle parameter, one vehicle parameter being used to represent one of the information of the vehicle.
Further, the at least one vehicle parameter may include at least one of:
a. identification of the vehicle. The identification may represent vehicles, with different vehicle identifications being different, thereby facilitating the differentiation of the individual vehicles by other vehicles.
b. The transmission time of the vehicle information. For example, the transmission time of the vehicle information is indicated by a time stamp, and other vehicles can determine the transmission time of the vehicle according to the transmission time and predict the current position of the vehicle by combining parameters such as the vehicle speed.
c. The vehicle is in a position. For example, the longitude and latitude of the vehicle or the position relative to a target object, which is a landmark building, road or roadside equipment, or the like.
d. Heading angle of the vehicle.
e. Longitudinal acceleration of the vehicle.
f. The type of vehicle. This type may be a car, truck or bus, etc.

h. Vehicle lamp status of the vehicle. Such as whether the vehicle's lights are on, the intensity of the lights that are on, the number of lights that are on, etc.
i. The condition of the vehicle braking anti-lock system. Such as whether the brake anti-lock system is active.
j. An auxiliary brake system for a vehicle. Such as whether the auxiliary braking system is active.
k. The brake pedal of the vehicle is depressed. Such as whether the brake pedal is depressed.
It should be noted that the above vehicle parameters are exemplary descriptions, and do not limit the embodiments of the present application in any way. It will be appreciated that other vehicle parameters may also be set depending on the use requirements.
In the embodiment of the application, the first vehicle-mounted terminal does not support V2X communication, but supports other communication protocols. For example, the communication protocol employed by the server with the first vehicle terminal includes at least one of: UU interface communication protocol, wireless fidelity (wireless fidelity, wiFi) interface protocol, bluetooth (blue) interface protocol.
Illustratively, the vehicle information is transmitted between the first vehicle terminal and the server via a UU interface communication protocol. If the network side issues a paging message including contents such as a paging record list (paging record list), an ETWS identifier (e tws-Indication), a paging UE identifier (paging UE-Identity), etc., the first vehicle terminal may establish an RRC connection with the network side. Then, the first vehicle-mounted terminal can send the collected vehicle information to the server through the Uu port, so that the server receives the vehicle information based on the Uu interface communication protocol.
It should be noted that, because the vehicle parameters of the vehicle are changed in real time during the driving process, for example, the vehicle position is always changed, in order to enable other vehicles to more timely learn the vehicle parameters of the vehicle, the vehicle may report the vehicle information to the server according to a preset period.
S202, the server generates a first message conforming to a first communication protocol according to at least one piece of vehicle information.
S203, the server sends a first message to the road side equipment.
S204, the road side equipment receives a first message based on a first communication protocol.
For vehicle information collected by a vehicle that does not support the V2X communication protocol, does not install the V2X-OBU, or does not function properly due to a V2X-OBU failure, the prior art has not specified what communication protocol to employ to transmit such vehicle information to the roadside device after the server obtains such vehicle information, i.e., the communication protocol between the server and the roadside device has not been specified. To this end, the present application proposes a first communication protocol. The first mode is that the first communication protocol is a V2X communication protocol, namely, a V2X communication protocol is adopted between a server and road side equipment to transmit messages; the second way is that the first communication protocol is a communication protocol other than a V2X communication protocol, for example, UU interface communication protocol, wiFi interface protocol, bluetooth interface protocol; in a third way, the first communication protocol is a completely new communication protocol, and the communication protocol specifies a protocol format for transmitting messages between the server and the roadside device.
Specifically, for the third mode, the first communication protocol may include:
(1) At least one field, each field for indicating a vehicle parameter.
(2) The type corresponding to each field.
(3) A data range corresponding to each field.
It should be noted that, in addition to the fields, the types corresponding to each field, and the data ranges corresponding to each field, the first communication protocol may define any other possible contents, which may be determined according to actual use.
Optionally, the first message generated based on the first communication protocol may include at least one of:
at least one field, each field for indicating a vehicle parameter;
a type corresponding to each field, the type corresponding to each field being determined based on the content of the vehicle parameter characterization of the respective field;
a data range corresponding to each field.
For example, table 1 is a correspondence table of fields in the first communication protocol, a type corresponding to each field, a protocol description, and a data range corresponding to each field provided in the present application.

Alternatively, the first communication protocol and the second communication protocol may be the same protocol or different protocols. For example, the first communication protocol is the brand new communication protocol provided in the above embodiment, and the second communication protocol may be a V2X communication protocol.
Further, the second information is basic security information (basic safety message, BSM).
Optionally, the first message is in the form of a first installation package and the second message is in the form of a second installation package. The vehicle-mounted terminal can decode the first installation packet according to the first communication protocol to obtain at least one vehicle parameter; and then, according to a second communication protocol, recombining at least one vehicle parameter into a second installation package, and broadcasting the second installation package according to the second communication protocol. It will be appreciated that the rate at which messages are transmitted in the form of installation packets is higher, i.e. the rate at which messages are transmitted is increased.
In this embodiment, when the first vehicle terminal that sends the vehicle information does not support V2X communication, and the second vehicle terminal that receives the vehicle information supports V2X communication, a server is introduced, so for a vehicle that does not support V2X communication, does not load V2X-OBU, or cannot normally work due to a V2X-OBU fault, various data collected by the vehicle may be sent to the server, and the server forwards these information to the road side device, so that the road side device may obtain the vehicle information, broadcast the vehicle information to surrounding vehicles through a V2X communication protocol, and further other surrounding vehicles that support V2X communication may receive the information, and perform V2V scene triggering according to the information.
Scene II:
for the scenario that the first vehicle-mounted terminal transmitting the vehicle information supports V2X communication and the second vehicle-mounted terminal receiving the vehicle information does not support V2X communication, two schemes are provided in the application:
the 1 st aspect is to change a communication protocol between the road side device and the second vehicle-mounted terminal to meet a requirement that the second vehicle-mounted terminal obtains vehicle information of the first vehicle-mounted terminal from the road side device, and specifically includes S301 to S308 described below.
S301, the server receives at least one piece of vehicle information. A vehicle information corresponds to a first vehicle terminal in communication with the server. The first vehicle terminal supports V2X communication.
A first possible implementation manner is that the first vehicle-mounted terminal is within a coverage area of the server, and the first vehicle-mounted terminal and the server both support V2X communication, so that the first vehicle-mounted terminal can transmit vehicle information of the vehicle to the server based on the V2X communication protocol, and the server receives at least one vehicle information based on the V2X communication protocol.
A second possible implementation manner is that the first vehicle-mounted terminal is within a coverage area of the server, the first vehicle-mounted terminal supports V2X communication, and the server does not support V2X communication, so the first vehicle-mounted terminal may transmit vehicle information of the vehicle to the server based on a UU interface communication protocol, a WiFi interface protocol, a bluetooth interface protocol, and the like.
A third possible implementation manner is that the server is connected to a plurality of roadside devices based on the first communication protocol, and the coverage area of each roadside device is different. Assuming that one first vehicle-mounted terminal is within the coverage area of the first road side equipment, the first vehicle-mounted terminal and the first road side equipment both support V2X communication, so that the first vehicle-mounted terminal can transmit vehicle information of the vehicle to the first road side equipment based on a V2X communication protocol, and then the first road side equipment sends the vehicle information to the server based on the first communication protocol. As such, the server may receive vehicle information from a plurality of in-vehicle terminals in the same or different coverage areas based on the first communication protocol. It should be noted that, for the first communication protocol, reference may be made to the description in the foregoing embodiment, which is not repeated here.
S302, the server generates a first message conforming to a first communication protocol according to at least one piece of vehicle information.
S303, the server sends a first message to the road side equipment based on the first communication protocol.
S304, the road side equipment receives a first message based on a first communication protocol.
It should be noted that the roadside device in S303 to S306 and the first roadside device in the third possible implementation manner may be the same device or different devices.
Taking the two as different devices as examples, after the first vehicle-mounted terminal transmits the vehicle information of the vehicle to the first road side device based on the V2X communication protocol, and the first road side device sends the vehicle information to the server based on the first communication protocol, the server may send the vehicle information of the plurality of vehicle-mounted terminals to at least one second road side device based on the first communication protocol.
Optionally, the first communication protocol is a V2X communication protocol, a UU interface communication protocol, or a completely new communication protocol provided in the foregoing embodiment, which is not limited in this embodiment.
And S305, the road side equipment generates a second message conforming to the second communication protocol according to the first message.
S306, the road side equipment transmits a second message based on a second communication protocol. The second message may be parsed by a second vehicle terminal. The second vehicle terminal does not support V2X communication.
S307, the vehicle-mounted terminal receives the second message based on the second communication protocol.
And S308, the vehicle-mounted terminal analyzes the second message based on the second communication protocol to acquire vehicle information contained in the second message.
Since the second vehicle-mounted terminal does not support V2X communication, the second communication protocol may be a UU interface communication protocol, a WiFi interface protocol, or a bluetooth interface protocol, which is not limited in this embodiment.
It should be noted that, for S301 to S308, reference may be made to the descriptions of S201 to S208 in the above embodiments, and the descriptions are not repeated here.
In this embodiment, when a first vehicle-mounted terminal that sends vehicle information supports V2X communication and a second vehicle-mounted terminal that receives vehicle information does not support V2X communication, a server is introduced between the first vehicle-mounted terminal and a road side device, and a communication protocol between the road side device and the second vehicle-mounted terminal is changed, so that various data collected by the first vehicle-mounted terminal can be sent to the server, and the server forwards the information to the road side device, so that after the road side device obtains the vehicle information, the vehicle information can be sent to surrounding vehicles through other communication protocols, and then other vehicles that do not support V2X communication, do not load V2X-OBU or cannot normally work due to V2X-OBU faults can receive the information, and V2V scene triggering is performed according to the information.
In the 2 nd scheme, the first vehicle-mounted terminal sends the vehicle information to the road side device, and the road side device sends the vehicle information to the server, and then the server forwards the vehicle information to the second vehicle-mounted terminal, which specifically includes S401 to S408 described below.
S401, the road side equipment receives at least one piece of vehicle information. A vehicle information corresponds to a first vehicle terminal in communication with the roadside device. The first vehicle terminal supports V2X communication.
In this embodiment of the present application, the first vehicle-mounted terminal and the road side device both support V2X communication, so the first vehicle-mounted terminal may send vehicle information based on the V2X communication protocol, and correspondingly, the road side device may receive vehicle information based on the V2X communication protocol.
S402, the road side equipment generates a first message conforming to a first communication protocol according to at least one piece of vehicle information.
S403, the road side equipment sends a first message to the server based on the first communication protocol.
S404, the server receives and analyzes the first message based on the first communication protocol.
Reference may be made to the description of the above embodiments for the first communication protocol, which is not repeated here.
S405, the server generates a second message conforming to the second communication protocol according to the parsed first message.
S406, the server transmits a second message based on a second communication protocol. The second message may be parsed by a second vehicle terminal. The second vehicle terminal does not support V2X communication.
S407, the vehicle-mounted terminal receives the second message based on the second communication protocol.
S408, the vehicle-mounted terminal analyzes the second message based on the second communication protocol to acquire vehicle information contained in the second message.
Since the second vehicle-mounted terminal does not support V2X communication, the second communication protocol is different from the V2X communication protocol, for example, the second communication protocol is a UU interface communication protocol, a WiFi interface protocol, or a bluetooth interface protocol, which is not limited in this embodiment.
It should be noted that, for S401 to S408, descriptions of S201 to S208, S301 to S308 may be referred to in the above embodiments, and are not repeated here.
In this embodiment, when the first vehicle-mounted terminal that sends the vehicle information supports V2X communication, and the second vehicle-mounted terminal that receives the vehicle information does not support V2X communication, various data collected by the first vehicle-mounted terminal may be sent to the roadside device by using the V2X communication protocol, and the roadside device forwards these information to the server, so that after the server obtains the vehicle information, the server may send the vehicle information to the surrounding vehicles through other communication protocols, and further other vehicles that do not support V2X communication, do not load V2X-OBU, or vehicles that cannot normally work due to the V2X-OBU fault may receive the information, and perform V2V scene triggering according to the information.
Scene III:
for the first vehicle-mounted terminal sending the vehicle information and the second vehicle-mounted terminal receiving the vehicle information do not support V2X communication, the communication protocol between the road side equipment and the second vehicle-mounted terminal is changed so as to meet the requirement that the second vehicle-mounted terminal obtains the vehicle information of the first vehicle-mounted terminal from the road side equipment, and the method specifically comprises S501 to S508.
S501, the server receives at least one piece of vehicle information. A vehicle information corresponds to a first vehicle terminal in communication with the server. The first vehicle terminal does not support V2X communication.
In a first possible implementation manner, the first vehicle-mounted terminal is within the coverage area of the server, and because the first vehicle-mounted terminal does not support V2X communication, the first vehicle-mounted terminal may transmit vehicle information of the vehicle to the server based on a UU interface communication protocol, a WiFi interface protocol, a bluetooth interface protocol, or the like, so that the server receives at least one vehicle information.
A second possible implementation manner is that the server is connected to a plurality of roadside devices based on the first communication protocol, and the coverage area of each roadside device is different. Assuming that a first vehicle-mounted terminal is within the coverage area of the first road side device, because the first vehicle-mounted terminal does not support V2X communication, the first vehicle-mounted terminal may transmit vehicle information of the vehicle to the first road side device based on a UU interface communication protocol, a WiFi interface protocol, a bluetooth interface protocol, or the like, and then the first road side device may send the vehicle information to the server based on the first communication protocol. As such, the server may receive vehicle information from a plurality of in-vehicle terminals in the same or different coverage areas based on the first communication protocol. It should be noted that, for the first communication protocol, reference may be made to the description in the foregoing embodiment, which is not repeated here.
S502, the server generates a first message conforming to a first communication protocol according to at least one piece of vehicle information.
S503, the server sends a first message to the road side equipment based on the first communication protocol.
S504, the roadside device receives the first message based on the first communication protocol.
It should be noted that the roadside device in S503 to S506 and the first roadside device in the second possible implementation manner may be the same device or different devices.
Taking the two as different devices as examples, after the first vehicle-mounted terminal transmits the vehicle information of the vehicle to the first road side device based on the UU interface communication protocol and the first road side device sends the vehicle information to the server based on the first communication protocol, the server may send the vehicle information of the multiple vehicle-mounted terminals to at least one second road side device based on the first communication protocol.
Optionally, the first communication protocol is a V2X communication protocol, a UU interface communication protocol, or a completely new communication protocol provided in the foregoing embodiment, which is not limited in this embodiment.
S505, the road side equipment generates a second message conforming to a second communication protocol according to the first message.
S506, the road side equipment transmits a second message based on a second communication protocol. The second message may be parsed by a second vehicle terminal. The second vehicle terminal does not support V2X communication.
S507, the vehicle-mounted terminal receives a second message based on a second communication protocol.
S508, the vehicle-mounted terminal analyzes the second message based on the second communication protocol, and vehicle information contained in the second message is obtained.
Since the second vehicle-mounted terminal does not support V2X communication, the second communication protocol may be a UU interface communication protocol, a WiFi interface protocol, or a bluetooth interface protocol, which is not limited in this embodiment.
It should be noted that, for S501 to S508, descriptions of S201 to S208, S301 to S308, and S401 to S408 may be referred to in the above embodiments, and are not repeated here.
In this embodiment, when the first vehicle-mounted terminal that sends the vehicle information and the second vehicle-mounted terminal that receives the vehicle information do not support V2X communication, a server is introduced between the first vehicle-mounted terminal and the road side device, and a communication protocol between the road side device and the second vehicle-mounted terminal is changed, so that various data collected by the first vehicle-mounted terminal can be sent to the server, and the server forwards the information to the road side device, so that after the road side device obtains the vehicle information, the vehicle information can be sent to surrounding vehicles through other communication protocols. In this way, other vehicles that do not support V2X communications, are not loaded with V2X-OBU, or are not working properly due to V2X-OBU failure can receive this information and perform V2V scene triggering based on this information.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
Fig. 3 is a schematic diagram of an application scenario of an information interaction method according to an embodiment of the present application. As shown in fig. 3, a vehicle a and a vehicle b traveling in the direction indicated by the arrow in lane 1 and a vehicle c traveling in the direction indicated by the arrow in lane 2 are about to meet at the intersection.
Assuming that the vehicles a and b are located within the coverage of the server d, the vehicles a and b do not support the V2X function, but support the mobile communication function. Vehicle information can be collected during the running of the vehicles a and b, and the vehicle information can be sent to the server d through a Uu port, so that the server d can receive the vehicle information of the vehicles a and b and generate a first message based on a first communication protocol, wherein the first message comprises: at least one field, each field for indicating a vehicle parameter; a type corresponding to each field, the type corresponding to each field being determined based on the content of the vehicle parameter characterization of the respective field; a data range corresponding to each field. Server d then sends the first message to roadside device e in a first communication protocol. Then, the road side device e receives the first message based on the first communication protocol, generates a second message conforming to the V2X communication protocol according to the first message, and transmits the second message based on the V2X communication protocol, so that the vehicle c supporting the V2X communication protocol can receive and parse the second message, thereby obtaining the vehicle information of the vehicle a and the vehicle b. In this way, it is achieved that the vehicle c supporting the V2X communication protocol acquires the vehicle information of the vehicles a and b that do not support the V2X communication protocol in the surroundings.
Further, after the vehicle c receives the vehicle information of the vehicle a and the vehicle b, the vehicle c can accurately estimate the current running states and running tracks of the vehicle a and the vehicle b according to various vehicle parameters of the vehicle a and the vehicle b, and whether the risk of collision exists, such as forward collision early warning of adjacent lanes, forward collision early warning of the same lane and collision early warning lamps of an intersection, so as to perform running adjustment. For example, as shown in fig. 3, assuming that the vehicle c predicts that a collision is imminent at the intersection of the lane 1 and the lane 2 after 20 seconds, the vehicle c may quickly make an adjustment of automatically decelerating to a safe speed, stopping, or whistling, etc., before the collision occurs, thereby reducing the possibility of occurrence of a traffic accident.

As shown in fig. 4, the road edge side is provided with a roadside apparatus 41 and a roadside apparatus 42, and coverage areas of the two roadside apparatuses have overlapping areas. When the vehicle 43 travels rightward along the arrow, the vehicle 43 may transmit the collected vehicle data to the server 44 based on the Uu communication protocol. The server 44 may determine that the vehicle is within the coverage area of the roadside device 41 and forward the vehicle data to the roadside device 41, 42 so that the roadside device 41, 42 may obtain the vehicle information and broadcast the vehicle information over the V2X communication protocol so that the vehicle 46 within the coverage area of the roadside device 41 may receive the information and the vehicle 45 within the coverage area of the roadside device 42 may receive the information. Since the vehicle 43 runs opposite to the vehicle 45 and the vehicle 46, the vehicle 45 and the vehicle 46 can avoid the vehicle 43 in time.

A communication module 51, configured to transmit the second message based on the second communication protocol; the second message may be parsed by a second vehicle terminal. Wherein the first vehicle-mounted terminal and/or the second vehicle-mounted terminal does not support V2X communication.
Taking the example that the first vehicle-mounted terminal does not support V2X communication, the second vehicle-mounted terminal supports V2X communication. After the first vehicle-mounted terminal collects various data, the data can be sent to the server through the Uu port, so that the server generates a first message based on a first communication protocol and sends the first message to the road side equipment by adopting the first communication protocol. The working process of each module in the road side equipment is as follows: receiving the first message by the communication module 51 and sending the first message to the processing module 52; the processing module 52 generates a second message according to the second communication protocol according to the first message and sends the second message to the communication module 51; the communication module 51 broadcasts the second message based on the V2X communication protocol.

And the processing module 62 is configured to parse the second message to obtain vehicle information contained in the second message.
Taking the example that the first vehicle-mounted terminal supports V2X communication, the second vehicle-mounted terminal does not support V2X communication. After the first vehicle-mounted terminal collects various data, the data can be sent to the server based on the V2X communication protocol, so that the server generates a first message based on the first communication protocol and sends the first message to the road side equipment by adopting the first communication protocol. The road side equipment generates a second message conforming to a second communication protocol according to the first message, and broadcasts the second message based on a UU interface communication protocol.
