Problems solved by technology

However, the disadvantage of this solution is that the sensing range of sensors such as cameras, microwaves, and radars is limited, and the maximum distance is usually within 200m, which cannot cover all roads; and the installation and maintenance costs are high, and the economic benefits are low

Abstract

The invention discloses a cooperative perception system, method and vehicle based on a V2X system, including an autonomous sensor module, a V2X communication terminal, a GNSS positioning system, a driving assistance system and a human-computer interaction system. The present invention obtains the surrounding target obstacle information through the autonomous sensor on the vehicle equipped with the V2X communication terminal, and broadcasts it through the V2X wireless communication system; other vehicles equipped with the V2X communication terminal can pass through the The V2X communication system perceives the existence of target obstacles; since this method does not need to add additional roadside terminals and vehicle hardware devices, it is low in cost and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and in particular relates to a V2X system-based cooperative perception system, method and vehicle. Background technique [0002] As V2X technology and related standards gradually mature, the time for large-scale application is getting closer. However, for a long period of time in the future, vehicles equipped with V2X systems and ordinary vehicles not equipped with V2X systems that cannot communicate with other vehicles will coexist in the market for a long time, resulting in social and economic benefits that V2X systems cannot produce. [0003] The current solution to this problem is mainly through the large-scale installation of V2X roadside communication terminals and sensors such as cameras, microwaves, and radars on the roadside; the sensors detect pedestrians, vehicles, etc. in the area, and push the detection results to the equipment through the V2X communication system V...
