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 sensing system and method based on a V2X system and a vehicle. The cooperative sensing system comprises an autonomous sensor module, a V2X communication terminal,a GNSS positioning system, a driving assistance system and a man-machine interaction system. According to the invention, surrounding target obstacle information is obtained through an autonomous sensor on a vehicle provided with the V2X communication terminal and is broadcasted through a V2X wireless communication system; other vehicles provided with the V2X communication terminals can sense theexistence of the target obstacle through the V2X communication system after receiving the message; according to the method, a roadside terminal and vehicle-mounted hardware equipment do not need to beadditionally added, so that the cost is low, and the architecture is simple.

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...
