基于OBD技术的驾驶习惯的参数化指标研究

目的驾驶员行为习惯的参数化研究对于评价驾驶员的驾驶水平有很重要的意义。本文根据驾驶习惯具有长期稳定的特点,基于车载诊断系统(OBD)技术分析驾驶参数并获得可靠的驾驶习惯评价指标。方法通过对各驾驶相关的参数进行时序稳定性检验,表明OBD提供的一些指标能作为驾驶习惯的参数化评估指标。结果通过OBD技术提取的一些参数具有时序稳定性,可以作为驾驶习惯的参数化指标。结论驾驶参数的稳定性是很多驾驶行为因果分析的隐含前提,本研究结论不仅能在一定程度上表征驾驶行为习惯,也为驾驶行为的因果研究提供了理论依据。

Study on the Parameterization Index of Driving Habits Based on OBD Technology

Objective To better evaluate different levels of drivers' ability, it is significant meaningful to dig deeper a lot of objective parameterization index of driving habits.According to the stability of driving habits, our research was based on OBD technology, an approach to get vehicle's self-diagnostic information, and to obtain the relative accurate evaluation indicator of driving habits.Methods First, we extracted the raw data including operation type, drive mile, acceleration, speed, engine speed and so on, which recorded by the OBD, and reduced the dimension of these raw data.Then, take these reduced dimension data into time-series stability test and extract some stable indicators which meeting our requirements to as the driving ability evaluation index.Results The result of stability test demonstrate that some parameterization indexes recorded by OBD can be used as a potential parameter for evaluating driving habits.Conclusion Our study can give a responsible evaluation of driving habits to a certain extent, but also provide a theory evidence for drive habits causal analysis.
