Safety early warning and control method and system for non-signal-control intersection

Abstract

The invention provides a safety early warning and control method and system for a non-signal-control intersection. The method comprises the following steps: acquiring the state of a target by adopting a millimeter-wave radar and a laser radar; correcting the obtained state of the target, and obtaining the corrected state of the target; training by using the corrected state of the target to obtain an optimized early warning model, wherein the early warning model is used for predicting the optimal early warning position of the target; and determining the optimal early warning position of the target by using the early warning model, and sending out an early warning signal according to the optimal early warning position of the target. According to the invention, a plurality of sensors such as a radar and a laser sensor applied to the unmanned driving field and a multi-element perception fusion technology are innovatively applied to the non-signal-control intersection, and compared with existing products in the market, the adaptability and the precision are greatly improved; and meanwhile, the product safety performance is greatly improved while the complete functions of the system are ensured.

Description

technical field [0001] The invention relates to a safety early warning and management and control system for a non-signature-controlled intersection, and belongs to the technical field of control systems and communications. Background technique [0002] As a necessary part of traffic, road intersections are important nodes in the construction of road networks, which carry traffic and connect roads. With the development of the economy and the increase in the number of vehicles, the probability of traffic accidents at urban road intersections and nearby areas is as high as 60%, and the proportion in rural areas is even higher. How to reduce the safety risk of non-trusted intersections and reduce the occurrence of traffic accidents is a technical problem that needs to be solved. [0003] In the context of the rapid development of unmanned driving, multi-sensor applications and multi-sensory fusion technology have been initially tried and achieved good results. However, this t...

AI Technical Summary

Problems solved by technology

Some solutions that have been adopted in the industry for non-signal-controlled intersections often only use a single sensing device, and the detection accuracy and applicable scenarios are limited. Usually, they only solve point-to-point problems for a single scenario, and the adaptability is insufficient, which brings It is impossible to flexibly adapt to problems under different scenarios (cities, national highways, etc.) and different environmental factors (such as vehicles, weather, road conditions, etc.)

At the same time, the systematic construction of existing products is insufficiently considered, the linkage and analysis with the back end are insufficient, and the detection data resources are not efficiently used
