It should be noted that descriptions such as first, second, third, fourth, and the like appearing in the following embodiments are only for distinguishing different objects, and do not constitute any other limitation.

Fig. 4 is a flowchart of an information interaction method according to an embodiment of the present application. The interaction subject of the method is a vehicle, a road side unit and a cloud server. Referring to fig. 4, the method flow includes:

401. the target vehicle sends service query information to the first roadside unit.

For example, the first roadside unit may be the roadside unit that is currently closest to the target vehicle. For example, the target vehicle may send the service query information to a roadside unit nearby after entering the road network.

The service query information is used for requesting the cloud server to query at least one service. The service may be any service that the cloud server can provide for the vehicle-side user in the car networking environment, including but not limited to weather service, road condition service (such as a road fault point), map service, music service, and the like, which is not specifically limited in this embodiment of the present application.

In the embodiment of the present application, whenever a target vehicle passes through one rsu, basic information of the target vehicle, such as driving data of the target vehicle, is reported to the passing rsu. In one possible implementation, the travel data may include a license plate number, a current travel speed, a travel direction, a destination, GPS (Global Positioning System) data, and the like. Wherein the GPS data is used to indicate the current specific geographical location of the target vehicle.

As an example, the target vehicle may send the service query information to the first road side unit in the form of a query request; in addition, the query request may also carry, for example, driving data of the target vehicle, which is not specifically limited in the embodiment of the present application.

402. After receiving the service query information sent by the target vehicle, the first road side unit generates an identity matched with the service query information and returns the identity to the target vehicle.

In this embodiment of the present application, after receiving service query information sent by a target vehicle, a first roadside unit first generates an identity identifier uniquely corresponding to the query request, where the identity identifier may also be referred to as an RID herein. I.e. one query request corresponds to one unique RID. Illustratively, the RID may be in a number form, an alphabet form, or a mixed form of numbers and alphabets, which is not particularly limited in the embodiments of the present application. After generating the RID, the first roadside unit may return the generated RID to the target vehicle immediately.

403. And the first road side unit sends the service query information, the identity identification and the current first running data of the target vehicle to the cloud server.

In order to distinguish the traveling data appearing here from the traveling data appearing later, the traveling data appearing here is referred to as first traveling data. And the first travel data refers to travel data of the target vehicle passing the first roadside unit.

In this embodiment of the application, the first road side unit may report the service query information sent by the target vehicle, the generated RID, and the current first driving data of the target vehicle to the cloud server, so as to be specifically processed by the cloud server, in addition to returning the generated RID to the target vehicle.

404. The cloud server processes the service query information and generates service response information matched with the service query information; and determining at least one target road side unit according to the current first running data of the target vehicle, and sending the identity and the service response information to the at least one target road side unit.

And the service response information generated by the cloud server corresponds to the service query information. For example, taking the service query information as an example for querying weather, the generated service response information may include weather information of the current geographic location of the target vehicle; taking the service query information as an example for querying the road condition, the generated service response information may include a road fault point, a water accumulation point, a congestion point, and the like occurring in front of the vehicle. In a possible implementation manner, the cloud server may process the service query information through a preset rule or a trained machine learning model, which is not specifically limited in the embodiment of the present application.

As an example, the current first traveling data of the target vehicle may include a current traveling speed of the target vehicle, GPS data of the target vehicle, and a current traveling direction of the target vehicle, and the cloud server may further determine a location of a roadside unit that the target vehicle may pass next according to the current traveling speed, GPS data, and traveling direction of the target vehicle, where the number of the roadside units determined by the cloud server may be one or more, and these roadside units are referred to herein as target roadside units.

In the embodiment of the present application, the next possible rsu that the target vehicle may pass through may be limited by a set time period, that is, the target rsu may be another rsu that the target vehicle may pass through within the set time period, except for the first rsu. For example, the set time period may be a numerical value such as 2 minutes or 5 minutes, which is not particularly limited in the embodiment of the present application.

Illustratively, the cloud server may send the identity and the service response information to at least one target rsu in a form of wireless broadcast.

For emutemutemutexample, referring to FIG. 5, when the target vehicle passes through the RSU-A, the target vehicle sends service query information to the RSU-A and receives the RID returned by the RSU-A. Then, the RSU-A uploads the service query information, the RID and the current driving data of the target vehicle to a cloud server; then, the cloud server determines that the next road side units which are possibly passed by the target vehicle are RSU-B and RSU-C according to the uploaded driving data; and then, the cloud server broadcasts the generated service response information and RID to the RSU-B and the RSU-C.

In this embodiment of the application, after receiving the identity and the corresponding service response information sent by the cloud server, any one target road side unit caches the identity and the corresponding service response information locally.

In one possible implementation, the cloud server sets a timeout time (referred to as a first timeout time herein) for the service response message sent to the target rsu, so that the service response message is deleted by the target rsu after the service response message fails. In another expression, after receiving data sent by the cloud server, any one target road side unit caches the received RID and the corresponding service response information locally until the service response information is deleted after being invalid. Namely, the embodiment of the present application further includes: the cloud server sends the first timeout time matched with the service response information to at least one target road side unit; and the at least one target road side unit locally caches the identity and the corresponding service response information, and deletes the locally cached identity and the corresponding service response information after the first timeout is reached.

In another possible implementation manner, the cloud server further sets a timeout time (referred to as a second timeout time herein) for the locally cached service response information, so as to delete the locally cached service response information after the locally cached service response information fails. Namely, the embodiment of the present application further includes: the cloud server sets a second timeout time matched with the service response information; and after the second overtime is reached, the cloud server deletes the locally cached identity and the corresponding service response information.

It should be noted that the second timeout period is greater than the first timeout period, for example, the first timeout period takes 10 minutes, and the second timeout period takes 2 hours, which is not specifically limited in this embodiment of the application.

405. When the target vehicle passes through the second road side unit, the identity mark is sent to the second road side unit; and the second road side unit locally searches whether the service response information matched with the identity is cached. If so, the following step 406 is performed.

During driving, the target vehicle may again pass through roadside units other than the first roadside unit (referred to herein as a second roadside unit). As shown in FIG. 5, the second road side unit passed by the target vehicle may be RSU-B, RSU-C, or RSU-D, i.e. the road side unit passed by the target vehicle nemutext may be any one other than RSU-A.

In this embodiment, when the target vehicle encounters the second roadside unit, the identity returned by the first roadside unit is automatically sent to the second roadside unit. Illustratively, after receiving the identity, the second roadside unit is responsible for retrieving whether service response information matched with the identity exists in a message queue of a local cache; if so, it indicates that the target vehicle may pass RSU-B or RSU-C as shown in FIG. 5.

406. And if the second road side unit locally retrieves the service response information matched with the identity, returning the service response information to the target vehicle.

In the embodiment of the application, if the second roadside unit locally retrieves the corresponding service response information, the service response information is returned to the target vehicle, so that the service response information is sent to the target vehicle, and the information interaction process is finished.

For example, after receiving the service response message, the target vehicle may display the service response message through a display screen, or broadcast the service response message in a voice broadcast manner, which is not specifically limited in this embodiment of the application.

In the method provided by the embodiment of the application, after the target vehicle sends the service query information to the first road side unit, the first road side unit generates the identity label matched with the service query information and returns the identity label to the target vehicle; then, the first road side unit also sends the service query information, the identity mark and current first running data of the target vehicle to a server, the server generates service response information matched with the service query information, determines at least one target road side unit according to the first running data, and sends the identity mark and the service response information to the at least one target road side unit; and then, when the target vehicle passes through the second road side unit, the target vehicle sends the identity identifier to the second road side unit, and if the second road side unit locally retrieves the service response information matched with the identity identifier, the corresponding service response information is returned to the target vehicle to complete information interaction. Based on the above description, it can be known that information interaction is carried out between vehicle and the road side unit, the road side unit is each other through the high in the clouds server cooperation based on V2X in this application embodiment, has reached the interactive effect of cooperation information, and this kind of diversification of information interaction mode has promoted the service quality to the vehicle under the driving environment, and is comparatively intelligent, the effect preferred.

605. When the target vehicle passes through other road side units again in the driving process, the identity mark is sent to other road side units; and other road side units locally search whether the service response information matched with the identity is cached. If so, the following step 606 is performed. If not, the following step 609 is performed.

606. And if the other road side units retrieve the service response information matched with the identity identification locally, returning the service response information to the target vehicle.
