Pedestrian automatic emergency braking system with active passive safety function

Abstract

Aiming at the problem that man-machine interaction and ground collision damage protection are not considered in existing achievement, the invention provides a pedestrian automatic emergency braking system with an active passive safety function. The system comprises a sensing system, a computing center, a man-machine interaction system, a pre-collision braking system and a post-collision braking control system; and the sensing system is responsible for sensing the environment outside a vehicle and monitoring human motion response in an accident in real time, the computing center is responsible for making a decision according to sensing information to guide other systems to work, the man-machine interaction system is composed of acousto-optic warning lamps installed on a roof and is responsible for warning pedestrians, the pre-collision braking system brakes the vehicle according to instructions of the computing center, and the post-collision braking control system controls the vehicle to brake according to instructions of the computing center. Compared with the prior art, the pedestrian automatic emergency braking system has the beneficial effects that the vehicle is braked before collision, pedestrians are warned to improve the accident avoidance rate, vehicle braking is controlled after collision to reduce human-ground collision damage, and accordingly the pedestrians are protected to the maximum extent.

Description

technical field [0001] The invention relates to the field of smart cars, and more specifically, to an automatic emergency braking system for pedestrians with active and passive safety functions. Background technique [0002] Judging from the existing research results of pedestrian automatic emergency braking system and the current situation of smart car collision accidents, it is difficult for smart cars to completely avoid collision accidents in the short term, and safety, especially the ability to protect vulnerable traffic participants A great obstacle to popularization and application. Therefore, it is necessary to explore a pedestrian automatic emergency braking system with active passive safety functions that actively avoids collisions beforehand and minimizes injuries afterwards, so as to quickly and effectively improve the ability of smart cars to protect vulnerable traffic participants. [0003] The existing pedestrian automatic emergency braking system does not co...
