Automobile intelligent safety protection and escape system and method based on elastic wave sensor

Abstract

The invention provides an automobile intelligent safety protection and escape system and method based on an elastic wave sensor, and belongs to the field of automobile electronic technology and active safety, the automobile intelligent safety protection and escape system comprises a risk sensing layer, an intelligent decision-making layer and a collaborative execution layer which are connected in sequence; the risk sensing layer comprises an elastic wave sensor network arranged at key parts of a vehicle and is used for collecting elastic wave signals in real time; the intelligent decision-making layer comprises a signal processing unit used for preprocessing the elastic wave signals and extracting feature information representing event types and intensity; the data fusion unit is used for fusing the feature information with data of other environment sensing sensors on the vehicle to generate a comprehensive environment sensing result; the decision control unit is used for identifying a risk event according to the comprehensive environment perception result and generating a corresponding grading response instruction; and the collaborative execution layer comprises one or more execution mechanisms and is used for responding to the grading response instruction and executing corresponding safety protection or emergency escape actions.
