基于深度学习的生态驾驶行为判别模型及矫正方法研究

Eco-driving is a primary countermeasure for solving the fuel consumption and gas emission problem. To establish the ‘classification-diagnosis-optimization’ process of driving behavior eco-characteristics, it is critical to uncover the hidden-relationships between exterior factors of traffic system, driving behavior and fuel consumption and gas emission. Therefore, in order to optimize eco-driving behavior, the key of this study is to build the driving behavior eco-characteristics identification and diagnosis model based on Deep Belief Networks (DBNs), through mining multi-dimensions and multi-causal eco-driving behavior recessive characteristics, on the basis of quantitatively analysis of big data of micro driving behavior. This study mainly aims to: 1) plot the specific chromatogram expression of the time-space evolving pattern of eco-driving; 2) establish the DBNs identification model, optimizing the critical parameters of behavior characteristics, and reaching the precise diagnosis of eco-driving behavior, by the means of the causality of input characteristics variables, network structure parameters and results of eco-driving identification; 3) build individualized correction and optimization model, and finally form an optimization theory and methodology, considering the whole process of identification-diagnosis-optimization of eco-driving behavior and the differences of drivers’ individual value and target orientation. This theory and methodology will lay the foundation of the popularization and application of eco-driving, and further deductively explore a method system of micro-driving behavior delicacy management, facing safe transport, green transport and smooth transport in big data era.
