将美国预估实际车速的 LAMM法与中国实际相结合提出了预估中国的 V85的方法 ,同时根据曲线上汽车制动时的受力特征 ,证明了径向摩擦力所能提供给车辆的最大径向加速度并非ψ· g,而是随 v2 / R的增大而减小 ,得出了计算最大径向加速度 amax的方法 ,并结合 V85和 amax指出曲线极限视距的计算方法。
The United States estimated the actual speed of the LAMM method and the actual situation in China put forward to predict China’s V85 method, at the same time based on the curve of the vehicle braking force characteristics prove that the radial friction can provide the maximum vehicle The radial acceleration is not ψ · g, but decreases with the increase of v2 / R. The method of calculating the maximum radial acceleration amax is obtained. The calculation method of the limit of line-of-sight of the curve is given in combination with V85 and amax.
