That is, in the auxiliary system of the present embodiment, the first information collecting unit 110 is disposed on the street lamp end 100, and the first information collecting unit 110 collects the first road information around the street lamp end 100 and sends the first road information to the nearby automatic driving vehicle; the automatic driving vehicle collects second road information around the vehicle through a second information collecting unit on the automatic driving vehicle, receives the first road information, and finally determines a driving strategy of the vehicle through the first road information and the second road information. Meanwhile, the road lamp terminal 100 receives the second road information, determines a target 500 that may affect the vehicle to travel according to the first road information and the second road information, and controls the warning unit 120 on the road lamp terminal 100 to send a warning to the target.
In the assistance system of this embodiment, since the vehicle end 200 finally determines the driving policy of the vehicle according to the first road information and the second road information, compared with the existing autonomous driving vehicle, the driving policy is determined only according to the second road information, because the road information obtained by the vehicle end 200 of this embodiment is more sufficient and comprehensive, the driving policy finally determined is obviously more reasonable and safer. In addition, the warning unit 120 on the street lamp terminal 100 warns the target of the possible danger of the target 500, thereby further reducing the possibility of traffic accidents.
In this embodiment, the second information acquisition unit specifically includes a second image acquisition module, a second radar module, and a second GPS module; the second image acquisition module is used for acquiring image information around the vehicle end 200, the second radar module is used for acquiring three-dimensional point cloud data around the vehicle end 200, and the second GPS module is used for acquiring position information of the vehicle end 200. The second image acquisition module may be a monocular and/or binocular camera, for example, the second radar module may include a millimeter radar wave radar and/or a laser radar, and the second road information includes road structure information, vehicle/pedestrian recognition, dynamic and static target recognition, position, speed, acceleration, heading of the vehicle end 200 itself, and state observation information of other vehicles and pedestrians around the vehicle end 200 itself, and the like.
The first information acquisition unit 110 specifically includes a first image acquisition module, a first radar module, and a first GPS module; the first image acquisition module is used for acquiring image information around the street lamp end 100, the first radar module is used for acquiring three-dimensional point cloud data around the street lamp end 100, and the first GPS module is used for acquiring position information of the street lamp end 100.
