Data processing method and system used for behavioral description of intelligent vehicle

Abstract

The embodiment of the invention relates to a data processing method and system used for the behavioral description of an intelligent vehicle. The method comprises the steps that environmental sensinginformation and vehicle state information are obtained; behavioral parameters and state parameters of the intelligent vehicle are extracted; behavioral parameters and state parameters of obstacles areextracted; execution object fields, driving action fields, to-be-executed object fields and constraint condition fields are generated; a driving statement structural model is called, and the fields are assembled into driving behavioral statement information; semantic recognition analysis is conducted on the driving behavioral statement to obtain a predicted running trajectory and state machine behavioral information of the intelligent vehicle; a running trajectory of the intelligent vehicle is generated. According to the method, through the driving statement structural model, description of the intelligent vehicle and target complicated behaviors can be accurately and clearly described in details so that the running trajectory of the intelligent vehicle can be accurately planned, the complicated degree of the system is simplified, and therefore the route planning time of the intelligent vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to a data processing method and system for intelligent vehicle behavior description. Background technique [0002] With the development of artificial intelligence technology and modern manufacturing industry, autonomous driving technology has gradually entered people's daily life, subtly changing the way people travel. Autonomous driving technology has great application prospects in both military and civilian applications. For military use, it can be used not only as an unmanned transportation platform, but also as an unmanned demolition vehicle, unmanned combat platform, unmanned patrol and surveillance vehicle, etc.; in civilian use, it can not only bring convenience to human life, but also reduce The incidence of traffic accidents and the improvement of road traffic efficiency. [0003] Autonomous driving behavior planning is an important part of driving bra...

Problems solved by technology

[0004] The label-based behavior description method in the prior art can only express simple motion behaviors, and cannot describe complex behaviors such as giving way and giving way, and the description of behaviors lacks depth, resulting in the inability of the vehicle to drive accurately; moreover, the existing technology A set of behavior description specifications has not been established, lack of standardization and modular structure, which is not conducive to the incremental generation of new behaviors; in addition, existing technologies usually use other methods to describe other target behaviors in the scene, increasing the complexity of the system
