Problems solved by technology

In practice, it is found that during the automatic driving process of the unmanned vehicle according to the preset route, when the unmanned vehicle encounters pedestrians or vehicles and the unmanned vehicle cannot continue to move, due to the lack of interaction with the surrounding pedestrians or vehicles, the surrounding pedestrians or vehicles Vehicles cannot obtain the driving intention of unmanned vehicles, so that pedestrians or vehicles will always be blocked on the automatic driving route, and effective avoidance between unmanned vehicles and obstacles cannot be achieved, resulting in road congestion
It can be seen that the existing unmanned vehicles cannot effectively interact with the surrounding environment when encountering obstacles during automatic driving, and the driving efficiency is low.

Abstract

The embodiment of the invention provides a driving prompting method and device for an unmanned vehicle, and relates to the field of automatic driving equipment. The method comprises the steps of judging whether the unmanned vehicle encounters an obstacle or not when the unmanned vehicle carries out automatic driving; if yes, acquiring obstacle information of the obstacle; and determining obstacleavoidance trajectory projection information according to the obstacle information. By implementing the implementation mode, unmanned vehicles (such as an unmanned vehicle and an automatic driving vehicle) can effectively interact with the surrounding environment in the automatic driving process, so that the driving efficiency can be improved.

Description

technical field [0001] The present application relates to the field of automatic driving equipment, in particular, to a driving prompt method for unmanned vehicles. Background technique [0002] At present, the application of unmanned vehicles is becoming more and more extensive, and is often used in delivery, express delivery, retail and other delivery fields. In practice, it is found that during the automatic driving process of the unmanned vehicle according to the preset route, when the unmanned vehicle encounters pedestrians or vehicles and the unmanned vehicle cannot continue to move, due to the lack of interaction with the surrounding pedestrians or vehicles, the surrounding pedestrians or vehicles Vehicles cannot obtain the driving intention of unmanned vehicles, so that pedestrians or vehicles will always be blocked on the automatic driving route, and effective avoidance between unmanned vehicles and obstacles cannot be achieved, resulting in road congestion. It can...
