Abstract

The invention discloses a vehicle state estimation method and device, electronic equipment, a storage medium and a vehicle. The vehicle state estimation method comprises the following steps: obtainingan image and identifying vehicle position information; and performing state estimation on the vehicle according to a fusion filter unit and the vehicle position information. The vehicle state estimation method solves the technical problem that the vehicle state estimation method is not good in effect. An improved vehicle speed and track estimation method is realized based on the fusion filter according to the characteristic that noise and measured noise statistic characteristics continuously change in a vehicle travelling process. Accuracy and robustness of vehicle state estimation are improved in a noise statistical signal conversion environment.

Description

Technical field [0001] This application relates to the field of estimation algorithms and signal processing, and in particular to a vehicle state estimation method and device, electronic equipment, storage medium, and vehicle. Background technique [0002] The speed and trajectory estimation of vehicles have a wide range of applications in the field of Internet of Vehicles systems and autonomous driving. [0003] The inventor found that the existing filters suitable for random estimation have poor effect on vehicle state estimation. Further, it affects the safety of driving. [0004] Aiming at the problem of poor effectiveness of vehicle state estimation methods in related technologies, no effective solutions have yet been proposed. Summary of the invention [0005] The main purpose of the present application is to provide a vehicle state estimation method and device, electronic equipment, storage medium, and vehicle, so as to solve the problem of poor effect of the vehicle state es...
