Embodiment Construction

[0061] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0062] This embodiment proposes a highway overtaking behavior decision method applied to autonomous vehicles. The overtaking behavior can not only meet the driving habits of specific drivers, but also meet the basic requirements of safety, comfort, and efficiency. overtaking behavior figure 1 In the second and third types of overtaking behavior, that is, the behavior of overtaking the vehicle ahead in this lane; the simple behavior of the first type of parallel overtaking will not be considered. The expressway facilities are complete, there are no pedestrians, no faulty vehicles, only motor vehicles running normally.

Abstract

The invention relates to an expressway overtaking behavior decision making method applied to an automatic drive vehicle. The method includes the following steps that S1, an overtaking intention model is established; S2, whether an overtaking intention is generated or not is judged; S3, if yes, S3 is executed, and if not, a lane keeping state continues to be kept; S3, whether overtaking conditions are met or not is judged, if yes, S4 is executed, and if not, the lane keeping state continues to be kept; S4, the vehicle gets into an overtaking sub-state. The overtaking intention is generated through an artificial neural network algorithm, and then judgment is carried out through safety, comfort and other conditions based on rules. The problems about whether it is necessary to carry out overtaking and whether overtaking succeeds or not are solved, the objective rules of the overtaking process are reflected, the subjective factors of the overtaking behavior are fully considered, and automatic drive shows the drive habits of human beings under the condition of guaranteeing overtaking safety, comfort and the like.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a decision-making method for expressway overtaking behavior applied to automatic driving vehicles. Background technique [0002] Intelligence is an inevitable trend in the development of the automobile industry, and autonomous driving technology is an important research content of automobile intelligence, and is therefore supported and encouraged by relevant national policies. In the "Made in China 2025" [22] issued by the State Council, it is clearly required that "by 2025, master the overall technology of autonomous driving and various key technologies." The U.S. government will launch a national blueprint for self-driving car standards across the United States in July 2016, and allocate $4 billion from the 2017 budget to support the research and development of self-driving technology. [0003] From the perspective of the development process of the industrialization ...
