Problems solved by technology

However, due to the fact that there are still dynamic driving participants such as pedestrians, bicycles, and cars in the actual traffic scene, the dynamic driving participants are uncertain and ambiguous
The model established by the artificial potential energy field is not effective for the risk perception of the uncertain and ambiguous dynamic driving participants, and it is difficult to make an accurate assessment of the risk probability. At this time, there are great hidden dangers in vehicle driving

Embodiment Construction

[0033] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their sequence is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0034] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "ex...

Abstract

The invention discloses a driving risk control method, a driving risk control device and a computer storage medium, relates to the technical field of risk early warning, and aims to solve the problemsthat the risk probability of driving participants cannot be accurately provided and the driving safety of vehicles cannot be ensured. The driving risk control method comprises the steps of receivingmotion information of at least two driving participants; determining that the risk degrees of the at least two driving participants are the same, and analyzing the motion information by utilizing a risk cloud model to obtain a distribution proportion of the risk probability of each driving participant in a preset distribution area, wherein the risk cloud model comprises at least one Gaussian clouddroplet model one of the risk degree, the mean value function of each Gaussian cloud droplet model is a potential energy field model function associated with the motion information, and the variancefunction is an uncertainty function associated with the motion information; and displaying the driving early warning information according to the distribution proportion of each driving participant inthe preset distribution area. The driving risk control device provided by the invention is used for executing the driving risk control method.

Description

technical field [0001] The present invention relates to the technical field of risk early warning, in particular to a driving risk control method, a driving risk control device, and a computer storage medium. Background technique [0002] In the process of driving a vehicle, it is necessary to perceive the surrounding environment and evaluate the driving risk to ensure safe driving, such as risk assessment for driving participants. [0003] At present, the model established by the artificial potential energy field is usually used to perceive the risk of the driving environment. The above-mentioned model established by the artificial potential energy field has a better effect on the risk perception and assessment of static obstacles such as trees and traffic signs. However, due to the fact that there are still dynamic driving participants such as pedestrians, bicycles, and cars in the actual traffic scene, the dynamic driving participants are uncertain and ambiguous. The mod...
