Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. In the description and in the claims "and/or" means at least one of the connected objects.

The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the spirit and scope of the disclosure. Various examples may omit, substitute, or add various procedures or components as appropriate. For example, the described methods may be performed in an order different than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

For the application scenario of C-V2X, many application scenarios involve information interaction with the road-end RSU, for example, in the "cooperative ramp merging" application scenario shown in fig. 1 to 2, at an entrance ramp of an expressway or expressway, a ramp vehicle HV sends a request message for merging into a main road to the road-end RSU, and the road-end RSU coordinates the vehicles HV on the ramp and the vehicles RV1 to RV2 on the rightmost lane of the main road by sending merging instructions (acceleration and deceleration, merging position, and the like), guides the vehicles on the ramp to safely and efficiently merge into the main road, and after the HV merges into the main road, may also report the current state of completed merging into the main road to the RSU, and the RSU may also notify the RV of completed merging into the RV and adjust the driving strategy of these RVs to the RV of the main road.

The road-end RSU can guide, suggest, decide and schedule the condition that vehicles converge into the ramp by collecting the information of vehicles on the main road and the ramp, and sends the service information of the convergence instruction to the main vehicle or the remote vehicle in the form of issuing the instruction, thereby cooperatively finishing the application scene of cooperative ramp convergence.

In the above application scenario, the vehicle end cannot know the reliability of the service information of the internet of vehicles, such as guidance, advice, decision, scheduling, and the like provided by the road end RSU. How to know the credibility of the guiding, suggesting, deciding, scheduling and other vehicle networking service information provided by the RSU and how much the vehicle networking service information provided by the RSU is credible, and in addition, when the guiding, suggesting, deciding, scheduling and other service information generated by the vehicle end per se is inconsistent with the service information provided by the RSU, the vehicle end should trust whether the self-generated service information is the service information provided by the RSU, and the prior art does not provide a solution.

In order to solve at least one of the above problems, an embodiment of the present invention provides a communication method in a car networking, where the method may be applied to a first device in the car networking, and specifically, the first device may be a road-side device (such as an RSU) in the car networking, or a multi-access edge computing device cloud device, or a certain vehicle (referred to as a first vehicle for convenience of description) in the car networking, and as shown in fig. 3 and fig. 4, the method includes:

step 41, the first device sends the first service information and the first reliability information of the first service information to the second vehicle.

Here, the first service information may be various service information in the internet of vehicles, for example, any service information related to road condition notification, vehicle guidance, vehicle driving advice, vehicle driving decision, and vehicle scheduling, and in addition, the first device may generate service information for the second vehicle according to related implementation manners of the prior art or according to related standards in the future, and the embodiment of the present invention does not specifically limit the type and the generation manner of the first service information.

And the first credibility information is used for indicating the credibility of the first business information so as to help a second vehicle to judge whether the first business information is credible or not. Specifically, the reliability information in the embodiment of the present invention may be indicated in different expression manners, for example, according to the order from low reliability to high reliability, the reliability information is divided into:

1) Expressing based on the score: 0-100 percent (percent), and 100 minutes of full score;

2) Expressing based on the number of stars: 1 to 5 stars, and 5 stars at most;

3) Expressing based on the grade: low, medium and high gears;

4) Expressing based on the grade: D. c, B and A are in four grades;

5)…

the above examples show some expression modes that may be adopted by the reliability information in the present invention, and of course, the present invention may also adopt other modes besides the above modes, as long as the communication parties know the expression mode of the reliability information in advance, and the present invention is not limited to this specifically.

Through the above steps, in the embodiment of the present invention, the first device may indicate the reliability of the service information sent by the first device to the second vehicle, so as to help the second vehicle to decide whether to adopt the service information sent by the first device.

According to at least one embodiment of the present invention, when the first service information and the first reliability information of the first service information are transmitted to the second vehicle, the first device may further transmit a first applicable condition of the first reliability information to the second vehicle, wherein the first applicable condition includes one or more of the following conditions: time, weather, road conditions, and traffic conditions. Specifically, the above-mentioned various conditions may include, but are not limited to, the following forms:

1) Time: such as day, evening or night, and the like, and can be specific time or period of the day, such as 8;

2) Weather: such as sunny days, cloudy days, foggy days, rainy and snowy days, etc.;

3) The road conditions are as follows: such as slippery roads or dry roads;

4) Traffic conditions: the information may be information reflecting smooth traffic or congestion, or vehicle density, such as dense or sparse vehicle

5)…

The above examples show several expression modes that the applicable conditions in the present invention can adopt, and of course, the present invention can also adopt other modes besides the above modes, as long as the communication parties know the expression mode of the applicable information in advance, and the present invention is not limited to this specifically.

Table 1 gives an example of the credibility information under different applicable conditions, and this example only takes the applicable conditions as weather as an example, wherein a sunny day is represented when the illumination intensity is greater than or equal to 500lx, and a cloudy day is considered otherwise. As can be seen from table 1, the same reliability information, for example, 5 stars, may indicate different reliabilities under different application conditions, in the embodiment of the present invention, a correspondence (specifically, may be represented in a table manner) between the first device and the second vehicle, where the correspondence is defined in advance, and the correspondence may be configured in advance, or the first device sends the reliability of each reliability information under different application conditions to the second vehicle.

TABLE 1

Through the mode, the embodiment of the invention can further introduce the application condition of the credibility information on the basis of the credibility information, thereby more accurately distinguishing the credibility of the same credibility information under different application conditions, improving the accuracy of the credibility indicated by the credibility information, better providing a decision basis for a vehicle end and further improving the safety of a vehicle networking system.

In the embodiment of the present invention, when a second vehicle receives first service information sent by a first device and first reliability information of the first service information, it may determine whether to adopt the first service information by itself, so as to determine whether to use a service behavior indicated by the first service information. In addition, the second vehicle may further evaluate the first service information and send evaluation information to the first device, where the evaluation information (for convenience of description, also referred to as first evaluation information herein) is used to reflect whether the first service information conforms to a current scene of the second vehicle, and may specifically be represented by an expression manner similar to the above reliability information, which is not specifically limited in this embodiment of the present invention.

In this way, the first device may further receive first evaluation information, which is sent by a second vehicle and is directed to the first service information, and then generate or update the first reliability information of the first service information according to the first evaluation information, or the first device may also forward the received first evaluation information, which is directed to the first service information, to a second device in the internet of vehicles, where the second device is a device different from the first device and includes, but is not limited to, a cloud device, a statistical computing center, and the like, and then the second device generates or updates the first reliability information of the first service information, and the first device may receive the first reliability information of the first service information generated or updated by the second device.

In addition, various evaluation algorithms may be adopted to evaluate the specific manner of generating or updating the reliability information of the service information based on the evaluation information, which is not specifically limited in the embodiment of the present invention.

Through the mode, the embodiment of the invention can realize the evaluation of the service information by the receiver based on each service information, and generate or update the credibility information of the generator or the sender of the service information, thereby realizing the acquisition or the improvement of the credibility information of the equipment.

In order to further improve the security of the evaluation process and ensure the accuracy of the device reliability information, the embodiment of the present invention may further introduce a traceable evaluation, for example, when the second terminal evaluates the first service information sent by the first device, in order to ensure that the evaluation is true and reliable, the second terminal sends the first evaluation information for the first service information to the first device in a traceable manner. At this time, the first device receives first evaluation information for the first service information, which is transmitted by the second vehicle in a traceable manner.

Specifically, the vehicle end traceable modes include, but are not limited to, the following modes:

1) Certificate tracing

The vehicle end acquires a unique digital certificate of the vehicle from a cloud certificate library of the vehicle end/cloud end, the digital certificate is uniquely bound with the vehicle end information, the vehicle end certificate information needs to be attached when service information is evaluated each time, when vehicle end evaluation is counted, the vehicle end certificate and message content (integrity) are checked through the certificate library, and evaluation information which fails in checking is discarded, so that malicious evaluation can be avoided, the evaluation credibility is ensured, and the evaluation credibility is increased.

At this time, when receiving the evaluation information of the first service information, the first device may further receive a digital certificate of the second vehicle sent by the second vehicle; then, the first device further verifies the digital certificate of the second vehicle, and generates or updates the first credibility information of the first business information after the verification is passed, or forwards evaluation information of the first business information to the second device in the internet of vehicles.

2) Username password tracing

The vehicle end can perform real-name binding in the cloud end in advance before evaluating the road end/cloud end service information, an evaluated user name and an evaluated password are sent through the real-name binding, when the vehicle evaluates the service information each time, the user name and the password are firstly used for logging in and then the evaluated information is sent, the road end/cloud end carries out statistical processing on the evaluation information submitted by the vehicle after the user name and the password are verified, and the statistical processing is refused to be carried out on the evaluation information submitted by the vehicle which is not verified by the user face and the password, so that the evaluation reliability is ensured, and the evaluation reliability is increased.

After the second vehicle successfully logs in the cloud end of the internet of vehicles by using the user name and the password which are registered and bound in the cloud end in advance through the real-name system, the first device receives the evaluation information aiming at the first service information sent by the second vehicle, and at the moment, the first device can generate or update the first credibility information of the first service information, or can forward the evaluation information of the first service information to the second device in the internet of vehicles.

The communication method of the internet of vehicles according to the embodiment of the present invention is described above from the first device side, and the flow of the above method at the second vehicle is described below.

Referring to fig. 3 and 5, when the communication method in the internet of vehicles provided by the present invention is applied to a second vehicle in the internet of vehicles, the method includes:

step 51, a second vehicle receives first service information sent by a first device and first credibility information of the first service information, wherein the first device is a road-side device, a cloud device, a first vehicle or a statistical calculation center in the internet of vehicles.

And step 52, the second vehicle judges whether to use the first service information according to the first credibility information.

Here, the second vehicle may ignore the first service information when the reliability indicated by the first reliability information is lower than a preset threshold (e.g., greater than or equal to 4 stars and 90 minutes, greater than or equal to 4 stars, greater than or equal to a high-grade, greater than or equal to a grade a, etc.); and when the credibility indicated by the first credibility information is not lower than a preset threshold, using the first service information.

According to different functions of the service information, using or ignoring the first service information may have different behaviors, for example, when the service information is road condition notification type information, using the first service information may be storing the first service information; ignoring the first traffic information may be discarding the first traffic information. For another example, when the service information is vehicle guidance information, the first service information may be used, such as controlling vehicle running according to the first service information, and discarding the first service information if the first service information is ignored.

In this way, the second vehicle can determine the reliability (mismatching) of the first reliability information based on the expression modes such as the score expression, the star number expression, the rank expression, and then determine whether to use the first service information based on the reliability (mismatching) of the reliability information.

Through the mode, the embodiment of the invention can provide the reliability of the service information to the second vehicle, thereby helping the second vehicle to decide whether to adopt the service information sent by the first equipment or not and improving the safety of the vehicle networking system.

In addition, when introducing the applicable condition of the reliability information, in step 41, when the second vehicle receives the first service information sent by the first device, the embodiment of the present invention may further receive a first applicable condition of the first reliability information sent by the first device; in this way, the second vehicle may determine the reliability of the first reliability information under the first application condition according to the reliability correspondence table of each reliability information under different application conditions, which is obtained in advance, and then proceed to step 52 to determine whether to use the first service information according to the first reliability information.

In addition, after the step 52, the second vehicle may further generate first evaluation information for the first service information; then, first evaluation information for the first business information is sent to the first device to help the first device or other devices to generate or update first credibility information of the first business information.

Specifically, the second vehicle may generate the evaluation information of the first service information in one or more of the following manners:

1) And the second vehicle compares second service information generated by the second vehicle with the first service information to obtain a first comparison result, and generates the first evaluation information according to the first comparison result.

For example, if the second service information generated by the second vehicle is the same as or similar to the first service information, evaluation information for positive evaluation may be generated for the first service information; and when the second service information is different from or greatly different from the first service information, evaluation information of negative evaluation can be generated for the first service information. The difference may be greater than a predetermined threshold.

2) And the second vehicle generates the first evaluation information according to the first use result of the first service information.

For example, after the second vehicle uses the first service information, the second vehicle may determine whether the first service information is good or bad according to a first usage result of the first service information, thereby generating positive or negative evaluation information. For example, if the first usage result is a negative usage result (e.g., a traffic accident occurs or there is a risk of causing vehicle driving safety or reducing vehicle driving efficiency), negative evaluation information may be generated, whereas if the first usage result is a positive usage result (e.g., no traffic accident occurs or there is no risk of causing vehicle driving safety or improving vehicle driving efficiency, etc.), positive evaluation information may be generated.

3) The second vehicle compares second service information generated by the second vehicle with the first service information to obtain a first comparison result, and generates the first evaluation information according to the first comparison result and a first use result of the first service information.

It is to be understood that the evaluation may be performed according to different criteria or evaluation algorithms in the embodiments of the present invention, and the above example is only one means that can be adopted in the embodiments of the present invention, and the embodiments of the present invention are not limited in this respect.

In addition, when introducing the traceable evaluation, the second vehicle may send first evaluation information for the first service information to the first device in a traceable manner.

For example, when the second vehicle sends the evaluation information of the first service information to the first device, the second vehicle may log in to the cloud of the internet of vehicles by using a user name and a password which are registered and bound in the cloud in advance through a real-name system; and then, after the cloud is successfully logged in, sending evaluation information of the first service information to the first equipment. Further, when the second vehicle sends the evaluation information of the first service information to the first device, the second vehicle may also send a digital certificate of the second vehicle to the first device.

The following describes the implementation of the vehicle networking communication method in the embodiment of the invention on both the first device and the second vehicle. Several examples of the communication method of the internet of vehicles to which the embodiments of the present invention are applied are further provided below with reference to the accompanying drawings. In the following examples, the first devices are all described by taking a road side RSU or a cloud device as an example.
