Title:
METHOD AND DEVICE FOR RECOGNIZING DRIVING BEHAVIOR OF VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/196879
Kind Code:
A1
Abstract:
A method and device for recognizing the driving behavior of a vehicle. The recognition method comprises: acquiring high-precision map information and feedback data of a target vehicle as collected by a sensor; acquiring target features of the target vehicle according to the feedback data and the high-precision map information; obtaining a probability value of the target vehicle according to the target characteristics and a Bayesian network, the probability value of the target vehicle being used to indicate the probability of occurrence of a behavioral state of the target vehicle, the behavioral state comprising a lane change cut-in driving behavior of the target vehicle, and the lane change cut-in driving behavior referring to a driving behavior in which the target vehicle changes lanes and cuts into the lane in which a self-driving vehicle is located; and recognizing a behavioral intent of the target vehicle according to the probability value of the target vehicle, the behavioral intent comprising the intent of the driving behavior in which the target vehicle changes lanes and cuts into the lane in which the autonomous vehicle is located. The method enables the automated driving vehicle to accurately recognize the behavioral intents of other vehicles.
