[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0047] Such as figure 1 As shown, the method for calculating the safe vehicle speed in a curve is for lateral instability events such as rollover and side slip that occur in the curve. Based on the road system technology, it is assumed that information interaction between the vehicle and the road is possible, and the vehicle has passed the calibration On the basis of fully considering the influence of people, cars and roads, a method for accurately calculating the safe speed of a vehicle entering a turn is established on the basis of the characteristic parameters of driving behavior. The method mainly includes the followi...
