Problems solved by technology
[0003] However, radar detection is not sensitive to biological obstacles. When the radar detects multiple obstacles, it cannot quickly distinguish the type of obstacle, that is, it cannot quickly determine that the obstacle is a biological obstacle, such as pedestrians, animals, etc. Or other non-biological obstacles, such as vehicles, bicycles, electric vehicles
The reflected wave of pedestrians is weak, and the resolution of radar to pedestrians is not high

The invention discloses a control method and control system for active braking of a vehicle, and the method comprises the steps: obtaining a near-infrared image in a set range around a vehicle, and extracting the coordinate information of a living body obstacle; acquiring point cloud data in a set range around the vehicle, determining a living body obstacle target, and acquiring a distance between the vehicle and the living body obstacle target; segmenting the point cloud data by utilizing the coordinate information of the organism obstacle to obtain a region of interest, and determining a motion trend of the organism obstacle by utilizing the region of interest; and when the vehicle or the environment within the set range around the vehicle meets the preset braking condition, using the distance between the vehicle and the organism obstacle target and the interested area for judging the motion trend of the organism obstacle, and controlling the vehicle to execute the active braking process. According to the invention, the motion trend of the living body obstacle can be predicted, and the active braking process of the suddenly occurring living body obstacle is realized.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and a control system for active braking of a vehicle. Background technique [0002] When the vehicle is driving at night, the radar installed on the vehicle is generally used to detect the biological obstacles in front of the vehicle, and according to the relative speed between the vehicle and the biological obstacles, and the vehicle and biological obstacles detected by the radar According to the distance between vehicles, it is judged whether there is a risk of collision, and the driver adjusts the speed and driving route of the vehicle according to the risk of collision, so as to avoid the collision between the vehicle and biological obstacles. [0003] However, radar detection is not sensitive to biological obstacles. When the radar detects multiple obstacles, it cannot quickly distinguish the type of obstacle, that is, it cannot quickly determine that th...
