It should be noted that the vehicle may be a vehicle with an automatic driving capability or a vehicle without an automatic driving capability, and is not particularly limited in the embodiment of the present application.
Any roadside RSU device may receive, at the vehicle end, a first type of data broadcast, which may be understood to be for determining an overlapping coverage area. And since each of the roadside RSU devices broadcasts, the first type data includes a plurality.
In some embodiments, the first type data may indicate a coverage area of a currently corresponding roadside RSU device, and similarly, a plurality of the first type data may determine at least one overlapping coverage area, or no overlapping coverage area. As shown in fig. 3.
Step S120, when the vehicle is located in the overlapping coverage area, selecting target road-side RSU equipment for interaction according to the current driving intention of the vehicle, wherein the target road-side RSU equipment comprises road-side RSU equipment covering a subsequent driving area.
And judging whether the vehicle is positioned in the overlapping coverage area, and when the vehicle is positioned in the overlapping coverage area, selecting the target road side RSU equipment for interaction by the vehicle according to the current driving intention of the vehicle.
It will be appreciated that it may be determined whether the vehicle is located in the overlapping coverage area based on the speed of travel of the vehicle and the vehicle position (the autonomous vehicle may be a combined positioning result of the IMU + RTK/GPS).
In addition, the selected target road-side RSU device mainly refers to a road-side RSU device covering a subsequent driving area of the vehicle, that is, the road-side RSU device is selectable by the vehicle when the vehicle is determined to be located under different overlapping coverage areas according to the intention of the vehicle.
In some embodiments, the vehicle may be provided with a travel intent from a current overlapping coverage area to another overlapping coverage or non-overlapping coverage area.

And judging whether the vehicle exits from the second overlapping coverage area and is about to enter a third overlapping coverage area according to the current position of the vehicle, wherein the judgment of whether the vehicle exits or not needs to be carried out according to the current position of the vehicle because the vehicle travels from one overlapping coverage area to the next overlapping coverage area.
Further, switching target road-side RSU equipment for interaction or keeping interacting with the target road-side RSU equipment if the vehicle is judged to have exited the second overlapping coverage area and be about to enter a third overlapping coverage area according to the current position of the vehicle. That is, the target RSU device may be switched when entering the third overlapping coverage area (without the previous RSU device information, for example, the previous RSU device information corresponding to the second overlapping coverage area is relied on before), or may be kept interacting with the target RSU device when entering the third overlapping coverage area (while the previous RSU device information is still needed).
As shown in fig. 4, if the vehicle is in the overlapping area, the roadside RSU devices covered by the subsequent driving area may be screened according to the driving intention of the vehicle, for example, the roadside RSU a device enters the coverage area of the roadside RSU C device, but not the coverage area of the roadside RSU B device, the roadside RSU a device and the roadside RSU C device may be screened, and corresponding service interaction may be performed. For another example, when the roadside RSU a device enters the coverage area of the roadside RSU C device, the roadside RSU a device and the roadside RSU C device are screened out, but still interact with the roadside RSU B device.
In one embodiment of the present application, the method further comprises: receiving second type data broadcast by any RSU equipment at the road side, wherein each second type data is used for determining a supported preset service type; and determining target road-side RSU equipment for interaction based on the non-overlapping coverage area and the current position of the vehicle.

In specific implementation, when a plurality of RSU devices are screened out, the RSU devices give corresponding guiding opinions, and when the guiding opinions given by the RSU devices are different, the safest suggestion is selected. For example, in fig. 4, the opinion guided by the RSU a is that the vehicle can change lanes, and the opinion given by the RSU B is that the vehicle delays changing lanes, the suggestion of the RSU B is selected, so that the vehicle can run more safely.
It should be noted that the current preset safety level may be determined according to the current driving road, or may be determined according to the vehicle, for example, the level of some special vehicles may be higher than that of ordinary vehicles.
