Abstract

The embodiment of the invention discloses an autonomous prediction lane information model training method and device, and the method comprises the steps: obtaining historical vehicle state information and historical lane information, enabling the historical lane information to correspond to the historical vehicle state information, and enabling the historical vehicle state information to comprise historical vehicle high-precision positioning information and historical vehicle motion information; the historical lane information is position information of a lane through which the vehicle passes; according to the historical vehicle state information, the historical lane information and a first loss function, a first model is trained, the first model is a long-short-term memory recurrent neural network model, the first model is used for autonomously predicting the position information of a lane where the vehicle is about to pass, and the first model is trained by using a time-based back propagation algorithm; the first loss function is a minimum mean square error loss function. The problem that the lane cannot be matched due to the lack of the lane information is solved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a training method and device for an autonomous prediction lane information model. Background technique [0002] In automatic driving or vehicle-road coordination systems, many vehicle-side application models require smart vehicles or smart vehicle terminals to clarify the lane in which the vehicle is located, so that the real-time lane position of the vehicle can be used as the starting point for subsequent models. The vehicle-side application models, for example, vehicle Acceleration and deceleration control model, vehicle lane change model, etc. [0003] The basic idea of ​​vehicle lane matching is to match the high-precision positioning of the vehicle itself with the high-precision map information of the vehicle, because the data volume of high-precision map data is much larger than the existing map data, and there are many differences in the driving po...
