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,...
