The invention discloses a tank truck curve sideslip and rollover prevention speed limiting system based on vehicle-road cooperation. The system comprises a road side unit used for collecting curve information data, a vehicle-mounted unit used for collecting vehicle basic information data, a central processing unit, an alarm unit and a vehicle speed control unit, the road side unit and the vehicle-mounted unit are in communication connection with the central processing unit, and the central processing unit is in communication connection with the alarm unit and the vehicle speed control unit. The invention further discloses a tank truck curve sideslip and rollover prevention speed limiting method based on vehicle-road cooperation, the central processing unit calculates the critical vehicle speed of vehicle turning according to the road side unit and the vehicle-mounted unit, and calculates the safe vehicle speed of no sideslip or rollover when the vehicle enters the curve based on the critical vehicle speed; the central processing unit judges the sideslip or rollover risk level of the vehicle according to the real-time vehicle speed of the vehicle and carries out early warning or vehicle speed control. According to the invention, potential rollover danger can be predicted, pre-warning is carried out and active control is carried out, so that safe driving of the vehicle is ensured.

    本发明公开了一种基于车路协同的液罐车弯道防侧滑侧翻限速系统,包括用于采集弯道信息数据的路侧单元、用于采集车辆基本信息数据的车载单元、中央处理单元报警单元和车速控制单元,路侧单元和车载单元与中央处理单元通讯连接,中央处理单元与报警单元和车速控制单元通讯连接;本发明还公开一种基于车路协同的液罐车弯道防侧滑侧翻限速方法,中央处理单元根据路侧单元和车载单元计算车辆转弯的临界车速,并基于临界车速计算车辆进入弯道时不发生侧滑或侧翻的安全车速;中央处理单元根据车辆的实时车速判断其侧滑或侧翻风险等级并进行预警或车速控制。本发明能够预测潜在的侧翻危险,进行事前预警并主动进行控制,以保证车辆安全行驶。
