Abstract

The invention discloses an intelligent decision-making method for an unmanned vehicle based on motivation and risk assessment. First, the surrounding environment conditions and motivation are analyzed when the vehicle needs to change state in a high-speed environment. On this basis, the motivation to change the driving state is extracted, and it is taken as the core of behavior decision-making, and the decision is made only when there is motivation to trigger, while the current driving state remains in other cases. At the same time, a risk assessment model for the surrounding environment of unmanned vehicles is established to dynamically verify the decision-making results, judge the rationality of the decision-making, and calculate the optimal target point of the decision-making. The invention can avoid too many meaningless decisions of the decision-making system during the driving process of the unmanned vehicle, improve the calculation efficiency, and realize the real-time, efficient and safe driving decision of the unmanned vehicle under the dynamic uncertain environment.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle decision-making, in particular to an intelligent decision-making method for unmanned vehicles based on motivation and risk assessment. Background technique [0002] With the rapid development of computer and communication technology, self-driving cars have gained more and more attention. Major auto companies around the world are also stepping up research and development of higher-level technologies for autonomous driving. Advanced auxiliary technologies and decision-making algorithms such as BSD, CTA, IACC, etc. developed to cope with different scenarios have been put into the market one after another. Among them, behavior decision-making and planning in the face of various traffic environments and emergency situations is the core technology to ensure safe and efficient driving of vehicles. At present, driving behavior decision-making is mainly based on rule-based or learning algorithm-...
