A pedestrian collision avoidance system and method based on vehicle-road coordination

Abstract

The invention discloses a pedestrian collision avoidance system and method based on vehicle-road coordination. The system includes a vehicle-mounted module, a roadside module, a vehicle-road communication module, a central processing module, and a display and control module. The information interaction between the roadside module and the vehicle-mounted module is carried out through the vehicle-road communication module, and the data of the two are sent to the central processing module together. The central processing module fuses and processes the multi-source information, and sends instructions to the display and control module to perform anti-collision measure. The invention obtains wider and more accurate pedestrian information by means of vehicle-road coordination, determines the collision risk of pedestrians and vehicles, and then takes corresponding anti-collision measures to achieve the purpose of safe and intelligent assisted driving.

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
