Abstract

The invention discloses a method for predicting the interactive behavior of surrounding vehicles based on game theory. The method includes collecting the state information of the self-driving vehicle and the surrounding vehicles in real time; predicting the future trajectory of the self-driving vehicle and the surrounding vehicles; establishing a driving benefit evaluation function Calculate the income of the movement of the self-driving vehicle and the surrounding vehicles under different driving behaviors; use the method of game theory to model and analyze the interaction between the surrounding vehicles and the self-driving vehicle, and comprehensively consider the possible future movement of the surrounding vehicles and Its expected income under different interaction behaviors with self-driving vehicles is used to probabilistically predict the future interaction behavior of surrounding vehicles. The present invention fully considers the uncertainty of the trajectory brought about by the interaction between the autonomous vehicle and the surrounding vehicles, and predicts the possible future interaction behavior of the surrounding vehicles, so that the autonomous vehicle can make more decisions when planning. Safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a method for predicting the interactive behavior of surrounding vehicles based on game theory. Background technique [0002] Autonomous driving technology has the advantages of significantly improving traffic safety and reducing traffic congestion, which has attracted more and more attention. Autonomous driving technology usually mainly includes three parts: environment perception, decision-making planning and control execution. Vehicle decision-making planning is one of the key technologies to measure the intelligence level of vehicles. The development of intelligent decision-making technology can improve the ability of vehicles to deal with complex traffic scenarios. [0003] The decision planning of the vehicle mainly includes two parts: on the one hand, the self-driving vehicle needs to predict the movement of the surrounding environment before making a ...
