There are the entire vehicle mass, the position of mass center, cornering stiffness coefficients, steering - system stiffness and steeringratio.
这些基本参数包括整车质量、质心位置、前后轮侧偏刚度、后轴侧倾转向系数以及转向系刚度和传动比等。

According to vehicle driving conditions active front steering can achieve the desired steeringratio, which meets the flexibility at low speed and stability at high speed.
主动前轮转向可以根据汽车行驶状态实现理想转向传动比，能同时满足低速时的灵活性与高速时的稳定性要求。
