A method for changing a driving height position of a motor vehicle using an actively adjustable chassis, the chassis comprising a plurality of spring damper units and associated spring travel sensors, the respective spring damper units being arranged between a vehicle superstructure of the motor vehicle and associated wheels of the motor vehicle, the spring travel sensor is used for measuring the corresponding relative distance between the superstructure of the vehicle and the corresponding wheel, the spring travel sensor transmits a corresponding spring travel signal to an electronic open-loop and closed-loop control device of the motor vehicle, and the spring travel signal is filtered by frequency in the electronic open-loop and closed-loop control device. The frequency filtering first comprises band-pass filtering which divides the spring travel signal into a signal component excited by the wheel and a signal component excited by the vehicle superstructure and filters out the signal components excited by the vehicle superstructure, the frequency filtering then includes absolute value conversion of the band-pass filtered spring travel signal and subsequently includes low-pass filtering.

    一种用于使用可主动调节底盘改变机动车辆的行驶高度位置的方法,底盘包括多个弹簧阻尼器单元与相关联的弹簧行程传感器,这些相应的弹簧阻尼器单元布置在机动车辆的车辆上部结构与机动车辆的分配的车轮之间,弹簧行程传感器用于测量车辆上部结构距对应车轮的相应相对距离,弹簧行程传感器将相应的弹簧行程信号传输到机动车辆的电子开环与闭环控制装置,弹簧行程信号通过电子开环与闭环控制装置中的频率滤波,频率滤波首先包括带通滤波,带通滤波将弹簧行程信号分成由车轮激励的信号分量和由车辆上部结构激励的信号分量,并且滤除由车辆上部结构激励的信号分量,频率滤波然后包括对带通滤波后的弹簧行程信号的绝对值转换并且随后包括低通滤波。
