用该方法不必进行复杂的识别分析，即可准确、简单、快速地测得实际汽车的非簧载质量。

By this way the unsprung mass of an actual motor vehicle is able to be accurately, simply and quickly measured, so that any complicated identification can be avoided.

该控制律在簧载质量和非簧载质量的速度反馈上引入了时变的反馈增益，该反馈增益随路面激励主导频率的变化而实时调整。

The control gains which are tuned according to road frequency are used to the velocity feedback of the sprung mass and the unsprung mass.
