Embodiment Construction
[0132] In order to make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0133] 1) Vehicle-mounted devices, such as on-board unit (OBU), are generally installed on vehicles. In the ETC system, roadside units (road side unit, RSU) are erected on the roadside, and the OBU can communicate with the RSU, for example, Communication is via microwaves. When the vehicle passes the RSU, microwaves can be used for communication between the OBU and the RSU. In the electronic toll collection (ETC) system, the OBU uses dedicated short range communications (DSRC) technology to establish a microwave communication link with the RSU, which can realize Processes such as vehicle identification or electronic fee deduction.
[0134] Or, in addition to the OBU, the vehicle-mounted device may also be other device...

The invention relates to a vehicle-road cooperation method and device which can be applied to the Internet of Vehicles, such as V2X, LTE-V and V2V, or can be applied to the fields of intelligent driving, intelligent network connection vehicles and the like. A first device obtains first information including information of a road and / or information of objects on the road, the objects on the road include vehicles and / or pedestrians on the road. The first device determines the driving behavior of the first device according to the first information and the capability of the first device. Even if the capability of the first device cannot completely process the first information, the first device can determine the driving behavior of the first device according to a part of information of the first information so that the problem that the capability of the device cannot be completely matched with the roadside information is solved. According to the technical scheme provided by the embodimentof the invention, devices with different capabilities and different roads can be cooperated so that the passing efficiency and safety are improved.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a vehicle-road coordination method and device. Background technique [0002] Future travel needs to be safer, more efficient and faster, and traffic safety, traffic congestion, and environmental pollution are the three major problems facing the current transportation field, and they are also problems that must be solved to achieve future smart travel. To this end, it is currently proposed to build an intelligent operation management system to promote automatic driving of vehicles, and has established related key demonstration projects for smart highways and urban traffic. [0003] Regarding automatic driving, the roadside equipment can determine the movement information and state information of the target in the target area by detecting the target area, and send the movement information and state information of the target to the on-board equipment. In this...
