Wireless vehicle management system and method based on active safety platform

Abstract

The invention provides a wireless vehicle management system and method based on an active safety platform. A vehicle active safety technology and a wireless communication technology are combined, safety warnings can be provided for a driver, meanwhile, vehicle active safety data are collected, recorded and analyzed, and the driving habits of the driver are effectively fed back. The system is composed of an embedded processor, a sensing module, a data storage module, a power module, a vehicle information collecting module, an alerter, a wireless communication module, a server and the like. Road image information is collected through a camera arranged behind a vehicle windshield, and the embedded processor processes image data and extracts lane line deviation information and front vehicle distance information. When the vehicle deviates from a lane line, or the front vehicle distance is too short, or speed reduction is too large, alarm prompts are provided for the driver, meanwhile, the warning record function is triggered, and warning information is sent to the background server through a wireless network to be recorded and analyzed. The system and method have the advantages of being high in integration level and high in expandability, achieving visual self-learning and the like, and can improve the vehicle intellectualization level and effectively reduce the accident rate.

Description

technical field [0001] The present invention relates to the fields of automobile active safety and Internet of Vehicles. It is a system and method for providing safety warnings to drivers and performing driving analysis and decision-making to the background through a wireless network. It involves technologies such as image processing, embedded processing, wireless communication, and satellite positioning. . Background technique [0002] Road traffic accidents have become a common global safety problem. Taking the data of 2005 as an example, 43,443 people died in road collision accidents in the United States, 44,295 in Europe, and 97,864 in China, exceeding the sum of the United States, Europe, Japan and South Korea. Traffic accidents are the biggest cause of death among the 4-34-year-old group. Passive safety systems have been greatly developed and widely used in the past 10 years. Rearview mirrors, seat belts, and airbags have become standard equipment for many vehicles, bu...

Problems solved by technology

However, in practical applications, the vehicle ahead may not be equipped with the same vehicle forward collision avoidance warning system based on Internet of Vehicles technology. At the same time, most of the highways with the most severe forward collision consequences are in non-urban areas, and there are blind spots in wireless network coverage.

And the satellite positioning module determines the latitude and longitude information, uploads it to the background data center, and the background data center extracts and calculates the security information and sends the alarm information to the vehicle. The delay time of the entire loop will affect the real-time alarm

[0007] The application number is 201320165704.5, and the name is "Passenger Car Safety Early Warning System Based on Visual Perception and Internet of Vehicles", which extracts the driver's fatigue status and passenger abnormal status in the car through visual perception, and sends the data to the checkpoint through RFID. This method does not have Active safety functions such as lane departure warning and forward collision warning, vehicle safety driving data cannot be recorded
