Abstract

The invention relates to a method for realizing behavior decision of an automatic driving automobile, and belongs to the technical field of automatic driving automobiles. The method comprises the following steps: S1, constructing a signal lamp crossroad simulation training scene containing environmental uncertainty factors; s2, constructing an implicit quantile network model, including constructing a state space, an action space and a reward function; s3, optimizing the implicit quantile network model constructed in the step S2 by using a neural network; and S4, according to reward distribution information output by the implicit quantile network model optimized in the step S3, generating a behavior decision with risk perception capability in combination with a Wang function. According to the method, the risk caused by uncertain factors in the environment can be sensed, and the safety of the automatic driving automobile passing through the crossroad with the signal lamp is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic driving vehicles, and relates to a method for realizing behavioral decision-making of automatic driving vehicles. Background technique [0002] When an autonomous vehicle operates in a real environment, its decision-making system needs to consider various factors of the environment, including surrounding vehicles and pedestrians. However, when faced with complex driving conditions, how to ensure the driving safety of autonomous vehicles remains unresolved. Especially at intersections with signal lights, how to consider the illegal behaviors of surrounding vehicles and pedestrians in the behavior decision-making system, such as running red lights and other dangerous behaviors, is very important to improve the safety of autonomous vehicles. [0003] At this stage, decision-making methods for autonomous vehicle intersections mainly include: rule-based decision-making methods, partially observable ...
