A smart prediction method and device for unmanned vehicle power supply in extreme rainstorm environment

Abstract

The invention discloses an intelligent predicting method and device for a power supply of a driverless vehicle under the extreme rainstorm environment. The intelligent predicting method adopts varioussensors, various environmental information of the driverless vehicle under the extreme rainstorm environment can be considered comprehensively, the rainfall resistance of a vehicle body is measured through force sensors, and data fusion is conducted through a hierarchical dispersion fusion algorithm; image collection is conducted through a Kinect camera, grey processing is conducted, thus an obtained accumulated water detecting image is concise and clear, and the detecting precision is high; the electrical quantity of the driverless vehicle under the extreme rainstorm environment is predictedin real time through a two-layer neural network, the use of the neural network takes full account of various quantitative and qualitative variable factors under the nonlinear environment, thus compared with a general SOC battery electrical quantity predicting method, the obtained electrical quantity predicting result is more intelligent, and the predicting result is more precise.
