Problems solved by technology

[0002] Although the development of modern transportation has brought endless convenience to people, it has also increased many potential safety hazards, especially the rapid development of expressways in my country. While it is convenient for people to travel, vehicle safety issues also follow. Not only is the route long, but the road conditions are complex and changeable. In addition to straight-line driving sections, there are also various driving environments such as tunnels, bridges, bends, ramps, and ramps. , constantly adjust the vehicle running state to adapt to a variety of road environments to ensure driving safety, but the driver's driving skills are limited after all, and some safety problems are difficult to avoid, requiring the driver to obtain information in advance to adjust the vehicle state, these The problem of vehicle safety not only causes great losses to people's lives and property, but also is not conducive to the development of my country's traffic safety cause.

Abstract

The invention discloses a vehicle monitoring and early warning system and method based on the Beidou navigation technology. The system comprises a transverse state monitoring unit, a longitudinal state monitoring unit, a steering wheel corner monitoring module, a ramp length monitoring unit, a correction parameter monitoring unit, a Beidou positioning module, a data storage module and a vehicle-mounted early warning prompt module which are all connected with a vehicle-mounted data processing unit. Based on the Beidou navigation technology, for driving states of a vehicle under different road conditions and in combination with the vehicle state information, the road environment information and navigation system information, the system is divided into a plurality of control modes according to a certain control strategy and algorithm to improve the adaptability and the pertinence of the system to different road conditions, and the control data is output to the vehicle-mounted early warning prompt module in real time, so that a driver is reminded to adjust the vehicle running state in time according to the difference of the driving environment, the road alignment and the vehicle running state, the driving safety is guaranteed, the overall response of the system is rapid through modular design, and the real-time performance is greatly improved.
