System and method for preventing pedestrians from collision based on vehicle-road cooperation

Abstract

The invention discloses a system and a method for preventing pedestrians from collision based on vehicle-road cooperation. The system comprises a vehicle-mounted module, a road-side module, a vehicle-road communication module, a central processing module and a display and control module. Information interaction between the road-side module and the vehicle-mounted module is realized by use of the vehicle-road communication module, and the data of the road-side module and the vehicle-mounted module both are sent to the central processing module; the central processing module is used for fusing and processing multi-source information and sending an instruction to the display and control module to execute a collision preventing measure. The system and the method for preventing pedestrians from collision based on vehicle-road cooperation have the advantages that more accurate pedestrian information within a wider range can be obtained in a vehicle-road cooperation manner and then the pedestrian-vehicle collision risk is determined, and furthermore, the corresponding collision preventing measures can be adopted, and therefore, the purpose of safe and intelligent driving aid can be achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a pedestrian collision avoidance system and method based on vehicle-road coordination. Background technique [0002] Since my country's traffic mode is still dominated by mixed traffic mode, that is, pedestrians, non-motor vehicles, and motor vehicles are often mixed on the roads of our country, so the collision between vehicles and pedestrians and non-motor vehicles in our country is the cause of traffic accident casualties. main reason. Some pedestrian anti-collision devices have been disclosed at home and abroad. [0003] A vehicle-road coordination device for warning drivers is disclosed in China (Chinese Patent No.: 201020289870.2). The vehicle-road coordination device directly prompts the driver on the adjacent vehicle of the information that there are non-motorized vehicles passing on the road, so that the driver can respond in advance. This device onl...

Problems solved by technology

This device only relies on on-board equipment to detect pedestrians in front, and the pedestrian detection capability is very limited, which is specifically reflected in: ① cannot solve the intersection building / vehicle occlusion problem; ② cannot cope with complex traffic environments (multiple pedestrians); ③ cannot cope with adverse light and harsh environment, at the same time, there are too many on-board equipment, the price is high, and it is difficult to promote
