The invention discloses a curved road safe speed calculating method and caution system based on vehicle infrastructure cooperation. The method includes the following steps of calculating the sideslip critical speed of a vehicle; calculating the rollover critical speed of the vehicle; comparing the small values of the two critical speeds and determining the safe speed when the vehicle runs into the curve; and calculating the safe vehicle speed when the vehicle runs into the curve after considering the behavior characteristics of a driver. The invention provides a method for accurately calculating the safe vehicle speed when the vehicle runs into the curve on the basis of fully considering the influences of people, vehicles and roads. Through the comprehensive considering of the vehicle motion characteristics and driver behavior characteristics, the safe vehicle speed of the vehicle at the curved road is analyzed by means of a vehicle dynamics theory. The method has the advantages of simple calculation, fast operation speed, and high reliability, and provides the theoretical method support for the design and development of a curved road safe driving caution system.
