Embodiment Construction

[0102] The technical solution in this application will be described below with reference to the accompanying drawings.

[0103] figure 1 It is a functional block diagram of the vehicle 100 provided by the embodiment of the present application.

[0104] In one embodiment, the vehicle 100 is configured in a fully or partially autonomous driving mode.

[0105] For example, the vehicle 100 can control itself while in an automatic driving mode, and can determine the current state of the vehicle and its surrounding environment through human operation, determine the likely behavior of at least one other vehicle in the surrounding environment, and determine the behavior of the other vehicle. The likelihood of the possible behavior corresponds to a confidence level for controlling the vehicle 100 based on the determined information. While the vehicle 100 is in the autonomous driving mode, the vehicle 100 may be set to operate without human interaction.

[0106] Vehicle 100 may inclu...

Abstract

The application, which relates to artificial intelligence, provides a behavior planning method and behavior planning device for an autonomous vehicle. The method includes: acquiring vehicle information, including locations of other N vehicles at an intersection; according to the locations of other N vehicles and an intersection point, determining (N+1) candidate vehicle gaps including a first vehicle gap, an intermediate vehicle gap, and an (N+1)th vehicle gap; and determining a target vehicle gap based on evaluation values of the (N+1) candidate vehicle gaps. The evaluation values are used for evaluating safety of the autonomous vehicle at the time of entering the intersection at the candidate vehicle gaps; and the target vehicle gap is used for enabling the autonomous vehicle to enter the intersection through the target vehicle gap. Therefore, the autonomous vehicle passes the intersection safely and rapidly.

Description

technical field [0001] The present application relates to the field of automatic driving, in particular to a behavior planning method and a behavior planning device for an automatic driving vehicle. Background technique [0002] Artificial intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is the branch of computer science that attempts to understand the nature of intelligence and produce a new class of intelligent machines that respond in ways similar to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-making. Research in the field of arti...
