Driving state analysis method and computer equipment using neural network algorithm

Abstract

The invention provides a driving state analysis method and computer equipment using a neural network algorithm. The method includes: using an acquisition device to collect data on the acceleration of the subject and the pressure of the seat on the back of the tester for multiple times in each driving state, and obtain multiple Groups of data, each group of data includes acceleration data and pressure data; multiple sets of data collected multiple times in each state are input into the pre-established model in batches to obtain multiple training output values ​​to form the output value range corresponding to the current state Set; collect the acceleration data and pressure data of the test subject at a moment in the driving process, input the model, and obtain the measured output value, compare the measured output value with the output value interval set obtained in the training stage, and based on the output value to which the measured output value belongs The set of value intervals determines the state of the test drive. Through the judgment and post-event analysis of the driving behavior of the test subjects, there is a quantitative data analysis method for the driver's driving behavior, which provides a more scientific analysis method.

Description

Technical field [0001] The present invention relates to the research field of driving behavior data analysis, in particular to a driving state analysis method using a neural network algorithm and a computer apparatus. Background [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the number of vehicles per capita is growing. Since vehicle driving has become an important behavior in daily life, and driving behavior is closely related to vehicle design, etc., the recognition of driving behavior also highlights its importance. [0003] In the prior art, there is a stress test system for testing the waist through the analysis of driving behavior in the traffic field, but it is limited to measurement, and there is no post-mortem analysis or judgment of the driver's behavior, and it is impossible to judge the driver's behavior state by means of pressure and acceleration. [0004] Therefore, judging the driving status of t...
