Problems solved by technology
In related technologies, it is impossible to automatically locate failure scenarios that do not match the actual road test, that is to say, it is impossible to effectively locate the problem (bad case) and pick it out
If the problem cannot be located, the vehicle’s lane change decision will be inaccurate, and the lane change accuracy rate will decrease when the vehicle’s lane change decision is made based on the vehicle’s lane change decision, making it difficult to guarantee the feasibility and accuracy of the lane change results in the actual driving process. safety

Embodiments of the present invention provide an information processing method, device, and storage medium, wherein the method includes: obtaining a second sample set according to the sample extraction strategy and the first sample set; In the case of obtaining at least two clustering information, the at least two clustering information is compared with at least two first data obtained in the actual driving of the vehicle, and the first data is obtained according to the comparison result. A feedback sample; according to the first feedback sample, locate a failure scenario that does not match the road test of the actual driving of the vehicle; modify the existing evaluation regression model according to the failure scenario located by the first feedback sample , according to the modified evaluation regression model for lane change selection. Adopting the embodiment of the present invention can improve the accuracy of lane changing.
Description
technical field [0001] The present invention relates to the technical field of information processing, in particular to an information processing method, device and storage medium. Background technique [0002] An application scenario of information processing is in the automatic driving of a vehicle. In order to realize the motion planning of the automatic driving of the vehicle, it is necessary to evaluate the trajectory of the vehicle. Vehicle lane change is an important part of motion trajectory. In the related art, it is impossible to automatically locate failure scenarios that do not match the actual road test, that is to say, it is impossible to effectively locate the problem (bad case) and pick it out. If the problem cannot be located, the vehicle’s lane change decision will be inaccurate, and the lane change accuracy rate will decrease when the vehicle’s lane change decision is made based on the vehicle’s lane change decision, making it difficult to guarantee the f...
