Embodiment Construction

[0035] The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

[0036] The technical solution of the present invention will be further described below in conjunction with the embodiments.

[0037] For a vehicle equipped with the said invention "an intelligent automatic emergency braking method for pedestrian protection", in an inevitable collision, pedestrians are protected by the following methods:

[0038] S1: When a pedestrian is found within the vehicle monitoring range, the vehicle flashes green and is ready to brake.

[0039] S2: When the risk of a collision between a person and a vehicle is detected, the vehicle flashes a yellow light and brakes the vehicle according to the distance between the person and the vehicle. The criterion for judging the risk of collision is as follows: assuming that the driving speed of a vehicle is v, the distance between the detected person and the vehicle is d, and the friction coeffic...

Abstract

Aiming at the problem that man-machine interaction and ground collision damage protection are not considered in existing achievement, the invention provides an intelligent automatic emergency braking method for protecting pedestrians. According to the method, interaction with pedestrians is achieved through acousto-optic warning before collision occurs, and a vehicle is controlled to move after collision so as to prevent the pedestrians from being damaged by collision. Compared with the prior art, the method has the beneficial effects that the vehicle is braked before collision, pedestrians are warned to improve the accident avoidance rate, the vehicle is controlled to move 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 intelligent automatic emergency braking method for protecting pedestrians. Background technique [0002] Judging from the existing research results of pedestrian automatic emergency braking methods and the current situation of smart car collision accidents, it is difficult for smart cars to completely avoid vehicle-person collisions 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 scheme 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 scheme does not consider at l...
