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.
本发明公开了一种基于车路协同的危化品运输车高速公路弯道防侧翻预警系统,包括车路信息交互系统、车辆侧翻判断系统、车‑路报警系统、车速主动控制系统。车路信息交互系统中路侧单元将前方弯道路况传输至车载单元;车辆侧翻判断系统通过建立临界车速计算公式,计算安全车速;车辆车速传感器将采集到的车速由物理变量转变为电信号输送至车载单元,车载单元将获取的车速与预警系统计算的车速阈值进行比对;车‑路报警系统在车辆速度大于或者等于车速阈值时,车路警报装置通过显示器对驾驶员进行车速过快预警。其可以提高危化品运输车进行侧翻预警的准确性和稳定性。
