To the condition of deviation from side path when vehicles are turning and braking, according to the deviation distance, the control strategies and control algorithms of vehicle braking stability by two control methods, yaw moment and active steering, are determined. The fuzzy controller are designed whose outputs can be adjusted online according to the variation of slip rate and dynamic proportionality factor. The simulation results prove that the method of fuzzy control which is based on the yaw meoment and front wheel active steering can improve vehicle braking stability and ability of path tracking.

针对汽车在转弯制动时出现的侧向路径偏离状况，根据偏离量大小，利用横摆力矩和主动转向两种控制模式分别进行汽车制动稳定性控制，确立了两种控制模式下的控制策略和控制算法，设计了模糊控制器，根据轮胎最优滑移率变化状况，对模糊输出变量论域的大小按照动态比例系数进行实时在线调整，仿真实验验证了所提出的基于横摆力矩和前轮主动转向的模糊控制方法能提高汽车制动稳定性和路径跟踪能力。

The large deviation theory,which is a more classical direction,seeks to control the probability of deviation of a random variable X from its mean M,i.e.one looks for upper bounds on Prob.

大偏差理论是一个更经典的方向，它是用来研究随机变量X与它均值偏差的概率，即寻找Prob的上界。

Thus when random fluctuations result in a deviation of the allele frequency between the parent and offspring generations, that deviation establishes new expected values for the allele distributions in the next generation to follow.

因此，当随机波动导致父母和子代之间产生等位基因频率出现偏差，这种偏差为紧接着的下一代的等位基因分布建立了新的预期值。

As a result, the mass matrix, the stiffness matrix, the damping matrix and the excitation coefficient matrices of the dynamics differential equations are random parameter matrices. According to the minimum deviation rule of the mean squares between the random parameter system and the deterministic parameter system, the random mean square deviation vector function between the two systems has been set up and the deterministic parameter system has been solved.

应用Newton-Euler矢量法对挂接车辆系统建立了质量阵、刚度阵、阻尼阵和激励系数阵皆为随机参数阵的八自由度随机参数系统动力学微分方程，并按照随机参数系统与确定性参数系统之间的均方值偏差最小的原则，建立了两系统之间的随机均方偏差矢量函数，由此解出了相应的确定性参数系统
