Driving state analysis method using neural network algorithm and computer equipment

Abstract

The invention provides a driving state analysis method using a neural network algorithm and computer equipment, and the method comprises the steps: carrying out the repeated collection of the acceleration of a tested person and the seat pressure data of the back of the tested person in each driving state through employing a collection device, obtaining a plurality of groups of data, and each groupof data comprises acceleration data and pressure data; inputting a plurality of groups of data acquired for multiple times in each state into a pre-established model in batches to obtain a pluralityof training output values, and forming an output value interval set corresponding to the current state; and acquiring tested acceleration data and pressure data at one moment in the driving process, inputting the tested acceleration data and pressure data into the model to obtain a measured output value, comparing the measured output value with the output value interval set obtained in the training stage, and determining the tested driving state based on the output value interval set to which the measured output value belongs. The driving behavior of the driver is quantitatively analyzed by judging the driving behavior of the tested person and analyzing the driving behavior after the driving behavior, and a more scientific analysis method is provided.

Description

technical field [0001] The invention relates to the field of driving behavior data analysis research, in particular to a driving state analysis method and computer equipment using a neural network algorithm. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the speed of the number of vehicles per capita is increasing. Since vehicle driving has become an important behavior in daily life, and driving behavior is closely related to vehicle design, 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 after-the-fact analysis or judgment on driver behavior, and it is impossible to analyze and judge driver behavior by means of pressure and acceleration. state. [0004] Therefore, it is ...
