    • In a height regulation system for a vehicle having an air spring suspension, the actual value (h) of the height of the vehicle body (10) is filtered with a short time constant (t1) to produce a first signal (NIV1) which is compared with a desired height (ho). The actual value (h) is also filtered with a longer time constant (t2) to produce a second (delayed) signal (NIV2) which can be compared with the desired value (ho). The selection of the first signal (NIV1) or the second signal (NIV2) is effected by an electronic switch (46) under the control of a velocity comparator (50). When the vehicle is at rest or moving at a relatively slow speed (below vo) at which large oscillations are not expected, the filter (40) with the shorter time constant (t1) is connected to the comparator (48) for comparison with the desired height (ho) whereas, at higher velocities (v>vo) the second filter (42) with the longer time constant (t2) is brought into use.
    • 在具有空气弹簧悬架的车辆的高度调节系统中,以短时间常数(t1)对车体(10)的高度的实际值(h)进行滤波,以产生第一信号(NIV1),其为 与期望的高度(ho)相比。 实际值(h)也用较长的时间常数(t2)滤波以产生可与期望值(ho)进行比较的第二(延迟)信号(NIV2)。 第一信号(NIV1)或第二信号(NIV2)的选择由电子开关(46)在速度比较器(50)的控制下实现。 当车辆静止或以不期望大的振荡的相对较慢的速度(低于vo)移动时,具有较短时间常数(t1)的滤波器(40)连接到比较器(48)以与 期望高度(ho),而在较高速度(v> vo)下,具有较长时间常数(t2)的第二过滤器(42)被使用。
