Automatic emergency braking system and method based on camera and cloud real-time map

The invention discloses an automatic emergency braking system and method based on a camera and a cloud real-time map. The automatic emergency braking system comprises an image data obtaining and processing module, cloud map data, a TTC threshold value dynamic prediction module and an emergency braking execution module. Obtaining an image in front of the vehicle shot by a vehicle-mounted camera, and calculating the TTC value of the vehicle and the potential dangerous vehicle; acquiring a crowdsourcing map of a cloud; predicting the next image calculation time and network delay according to the previous image data calculation time and the cloud data transmission delay so as to dynamically set a TTC (Time to Collision) threshold value of the two vehicles; the TTC threshold value obtained through calculation is compared with the TTC threshold value dynamically set, and graded braking decisions are automatically adopted. Compared with the prior art, the method has the advantages that the TTC can be predicted and d
