车辆操纵稳定性的半主动控制策略

Semi-active Control Strategy for Vehicle Handling Stability

为了有效的加强汽车转向行驶、变向行驶的稳定性,应对车辆操纵稳定性存在的问题,引入了半主动控制模型并以此为基础创造了控制的模型。通过对设定的参数的改变来达到修改车辆行驶路况的作用,可以适当的改变阻尼的大小、车身倾翻的程度,对于车辆行驶操纵的实际情况进行模拟。模拟实验的结果让我们了解到半主动控制有效的提高了车辆操纵的稳定性,减少了车辆变向行驶过程中倾角,也使得加速度缩小了一般,不稳定因素下降了35.2%。所以说半主动控制系统能够增强车辆操纵的稳定性,极大的减少车辆变向行驶侧倾的角度。

In order to effectively enhance the stability of vehicle steering and variable steering, and to deal with the problems of vehicle handling stability, a semi-active control model is introduced and a control model is creat- ed based on it. Through the change of the set parameters to modify the role of vehicle traffic conditions, you can change the size of the damping, the extent of the body tipping, the actual situation for vehicle driving simulation. The results of the simulation experiment let us understand that semi-active control effectively improves the stabili- ty of vehicle handling, reduces the inclination of the vehicle in the process of variable direction, also makes the acceleration reduced in general, unstable factors decreased by 35.2%. So that semi-active control system can en- hance the stability of vehicle handling, greatly reducing the direction of the vehicle to roll the roll.
