Abstract

The invention discloses a dangerous chemical transport vehicle highway curve anti-rollover early warning system based on vehicle-road cooperation. The dangerous chemical transport vehicle highway curve anti-rollover early warning system comprises a vehicle-road information interaction system, a vehicle rollover judgment system, a vehicle-road alarm system and a vehicle speed active control system.A road side unit in the vehicle-road information interaction system transmits the front curve road condition to a vehicle-mounted unit; the vehicle rollover judgment system calculates a safe vehiclespeed by establishing a critical vehicle speed calculation formula; a vehicle speed sensor converts the collected vehicle speed into an electric signal from a physical variable and transmits the electric signal to the vehicle-mounted unit, and the vehicle-mounted unit compares the obtained vehicle speed with a vehicle speed threshold value calculated by the early warning system; when the vehicle speed is larger than or equal to the vehicle speed threshold value, a vehicle road alarm device carries out vehicle overspeed early warning on a driver through a displayer. The system can improve the rollover early warning accuracy and stability of a hazardous chemical substance transport vehicle.

Description

technical field

[0001] The invention relates to the technical field of vehicle transportation safety, in particular to a roadway system-based rollover warning system for dangerous chemical transport vehicles on highway curves. Background technique

[0002] Vehicle-road coordination technology applies wireless communication technology and advanced sensor technology to vehicles to realize vehicle-road and vehicle-vehicle information interaction. Vehicle-road coordination technology is mainly composed of vehicle-mounted units, roadside units, and wireless communication technologies. The vehicle-mounted unit obtains the working condition information of the vehicle through the information equipment of the vehicle system, and the roadside unit can receive the information of the vehicle-mounted unit, share the collected road condition information with the vehicle through wireless communication technology, and provide security for the safe driving of the vehicle by adding an alarm d...
