    Abstract: The accuracy of safety speed is insufficient because the grandeur of a vehicle is oversimplified by the curve-safety-speed calculation method, which plays a core decision-making role in the current curve-speed warning control system. Based on the nonlinear characteristic of tire and dynamic stiffness of suspension, the vehicle dynamic model with TruckSim was built by using an 8-meter-long full-load bus as the research object. The orthogonal simulation experiment of driving speed to different radii was conducted, and the mathematical response surface model of safety speed to curve radius was established. Finally, the critical speeds of the mathematical model calculation and the simulation test were compared under the same bend radius. Results show that the mathematical response surface model is a reasonable and accurate calculation method for calculating the safety speed of a vehicle that is turning on a curve. This model benefits the enhancement of vehicle active safety control technology.
