Problems solved by technology

If the target vehicle actually turns left and is predicted to go straight, the ego vehicle 11 may decelerate in advance, reducing traffic efficiency and frequent acceleration and deceleration will bring a bad riding experience

Embodiment Construction

[0063] As used in this application, the terms "component," "module," "system" and the like are intended to refer to a computer-related entity, which may be hardware, firmware, a combination of hardware and software, software, or an operating system. software. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. As an example, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution and a component can be localized on one computer and / or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures thereon. These components can be communicated through, for example, according to having one or more packets of data (e.g., data from a component ...

Abstract

A method and device for predicting the exit of a vehicle, relating to the field of automatic driving, and used for realizing the prediction of the exit of a target vehicle at a target intersection. The method for predicting the exit of the vehicle includes: obtaining the first position of the target vehicle in the target intersection and the driving direction of the target vehicle (step S401); obtaining N reference points associated with the N exits of the target intersection, where N is positive Integer (step S402); According to the first position, the direction of travel of the target vehicle and N reference points, obtain the respective likelihoods corresponding to N exits, the likelihood represents that the target vehicle leaves the target intersection from its corresponding exits probability (step S403); obtain the exit with the highest likelihood corresponding to the N exits as the exit of the target vehicle (step S404).

Description

technical field [0001] The present application relates to the field of automatic driving, and in particular to a method and device for predicting exits of vehicles. Background technique [0002] Predicting the driving behavior of other vehicles is a very important technology in the field of autonomous driving, especially at intersections, it is very important to accurately predict the driving behavior of other vehicles. Due to the complex traffic flow and lack of lane markings at the intersection, it is very difficult to predict which exit other vehicles will take at the intersection. [0003] Exemplary, such as figure 1 As shown, assuming that the vehicle 11 will turn left at the intersection, the target vehicle 12 may turn left at the intersection and leave the intersection from the right exit, or may go straight to leave the intersection from the bottom exit. If the target vehicle 12 is actually going straight and is If it is predicted to turn left, the own vehicle 11 m...
