Problems solved by technology

The disadvantages are also obvious. Since only the position information of each obstacle is used, the effect of obstacle avoidance and path selection is poor.
[0005] Moreover, the impact of different road condition information at each moment is not considered, for example, the impact of changes in the number of roads, the impact of vehicle types, etc.
The existing method to determine the movement strategy of unmanned vehicles is not flexible and accurate enough

Abstract

The invention discloses a method and device for determining movement strategy of an unmanned vehicle. The unmanned vehicle collects images continuously in the driving process, and thus, an image collected at present time can be determined, the image is input to the coding end of a pre-trained decision model to obtain a road condition characteristic vector corresponding to the present time, and road condition characteristic vectors, obtained by the coding end of the pre-trained decision model historically, corresponding to different historical time, the road condition characteristic vector corresponding to the present time and a motion strategy of the unmanned vehicle at the present time are input to the decoding end of the decision model, and a motion strategy of next time of the unmannedvehicle is obtained.

Description

technical field [0001] The present application relates to the technical field of unmanned vehicles, in particular to a method and device for determining a movement strategy of an unmanned vehicle. Background technique [0002] An unmanned vehicle refers to an intelligent vehicle that senses the surrounding road environment through its own sensor system, automatically plans a driving route, and controls the vehicle to reach a predetermined target. [0003] In the prior art, a path planning method for unmanned vehicles uses an encoder-decoder structure based on a long-short-term memory network (LongShort-Term Memory, LSTM), by inputting the actual coordinates of obstacles at M moments in history , output the predicted coordinates of obstacles at N moments in the future, and control the driving of the unmanned vehicle according to the preset obstacle avoidance method. [0004] The biggest advantage of this method is that the model is simple and at the same time determine the w...
