A control method for preventing vehicle overturning comprises the following steps: a, the vehicle overturning critical angle alpha(0) of an existing railway is calculated; b, the vehicle frame inclination angle alpha(x) is measured; c, the vehicle frame inclination angle alpha(x) and the vehicle overturning critical angle alpha(0) are compared; d, a vehicle rotation working device can continue rotating if the vehicle frame inclination angle alpha(x) is smaller than the vehicle overturning critical angle alpha(0); the vehicle rotation working device stops rotating if the vehicle frame inclination angle alpha(x) is equal to the vehicle overturning critical angle alpha(0); and the vehicle rotation working device rotates back if the vehicle frame inclination angle alpha(x) is larger than the vehicle overturning critical angle alpha(0). According to the control method for preventing vehicle overturning provided by the invention, on the basis of a control system composed of a programmable logic controller (PLC for short), hardware transformation can be completed by adding an angle sensor and simple wiring only. A control device for preventing vehicle overturning provided by the invention in another aspect can simply prevent vehicle overturning on a large ultrahigh railway.
