Problems solved by technology

Even if the technology matures and the price drops to 1 / 10 of the current cost, the cost of OBU equipment and RSU equipment is still the biggest problem in deploying V2X systems

Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0035] Existing V2X uses OBU devices with DSRC or C-V2X communication capabilities for short-distance and timely communication. Taking vehicle collision detection as an example, the communication process of the existing C-V2X OBU device is as follows:

[0036] Step 1: The main vehicle continuously broadcasts its own status to surrounding vehicles through C-V2X during driving. Self-state information is included in the Internet of Vehicles protocol message, including vehicle driving position, vehicle identification, speed and acceleration and other information.

[0037] Step 2: If the slave car is within the broadcast communication distance of the master car (C-V2X is...

Abstract

The embodiment of the invention discloses a novel V2X system. The system comprises a vehicle-mounted central control unit of a main vehicle, a vehicle-mounted central control unit of a slave vehicle in the same cluster as the main vehicle, a vehicle-mounted central control unit of a slave vehicle in a cluster adjacent to the main vehicle, a low-layer cluster server, a top-layer cluster server andan adjacent low-layer cluster server. The units and the servers realize information interaction between the master vehicle and the slave vehicles by broadcasting, receiving and forwarding the Internetof Vehicles protocol messages, so that additional power consumption of braking, acceleration and the like of the vehicles is reduced, vehicle pollutant emission is reduced, traffic accidents are reduced, and traffic jam is relieved; a novel V2X system is deployed without depending on expensive OBU equipment and RSU equipment, and the cost and difficulty of system deployment are greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a novel V2X system. Background technique [0002] The V2X (Vehicle-to-Everything) system is used to realize the information exchange between the vehicle and all entities that may affect the vehicle. V2X mainly includes V2V (Vehicle-to-Vehicle, vehicle-to-vehicle), V2I (Vehicle-to-Infrastructure, vehicle-to-infrastructure), V2N (Vehicle-to-Network, vehicle-to-network) and V2P (Vehicle-to-Pedestrian , car connects people). Vehicles supporting V2X have greatly improved road safety and reduced the probability of collision accidents. [0003] However, the biggest problem currently hindering the commercial use of V2X is the cost issue. In order to deploy as figure 1 In the V2X system shown, an OBU (On Board Unit) needs to be installed on the vehicle, and an RSU (Road Side Unit) needs to be deployed on the roadside to support D2D (Device to Device) communication...
