Abstract

The invention discloses a driving behavior analysis and driving assistance system based on OBD. The vehicle driving data and failure information are acquired through an OBD diagnostic link, a GPS and an acceleration sensor are arranged additionally, a vehicle is monitored completely, the data are transmitted to a data center in a GPRS / 3G / 4G manner, the center classifies and summarizes the data before performing corresponded processing and feeds back the corresponded information including vehicle routine data flow, driving behavior analysis and other warning information to a vehicle user in a manner of the webpage or mobile communication so as to assist a driver, and the driver can drive safely and economically in an environment-friendly manner.

Description

technical field [0001] The invention relates to the technical field of passenger flow statistics, in particular to an OBD-based driving behavior analysis and driving assistance system. Background technique [0002] The rapid development of Internet of Vehicles technology and industry has made it possible to monitor vehicle operation, obtain and analyze real-time vehicle parameters, and assist and diagnose travel distances, thereby promoting the advancement of OBD (On-Board Diagnostics, vehicle fault diagnosis) technology. The traditional OBD has two main functions: one is to monitor the running status of the vehicle and display various car-related data in real time; the other is to call the police in time when the system fails, and give the cause of the failure and maintenance advice. [0003] At present, driving behavior analysis and driving assistance systems are divided into two categories: one is based on image recognition systems, such as fatigue driving warning system,...
