Abstract

The embodiment of the invention provides a method and system for predicting the state of an obstacle vehicle and belongs to the field of automatic driving. The method for predicting the state of the obstacle vehicle comprises the steps that state information of the obstacle vehicle at the current time is estimated; state information of the obstacle vehicle at the next time is estimated according to the state information at the current time; and driving behavior of the obstacle vehicle is judged according to the state information of the next time.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to a method and system for predicting the state of an obstacle vehicle. Background technique [0002] In recent years, unmanned driving-related technologies have received widespread attention. Among them, during the driving process of unmanned vehicles, it is necessary to use the state information of obstacle vehicles as constraints to plan the driving trajectory of unmanned vehicles. Usually, for the obstacle vehicle in front, we usually need to use it after a period of time instead of the current state as the constraint condition of the path planning algorithm, and the specific time depends on the driving state of the vehicle. Therefore, it is necessary to predict the state information of the obstacle vehicle in the future according to the current state information of the obstacle vehicle. [0003] In the process of implementing the present invention, the inventors of the...
