Abstract

Described is a process for conditioning of sensor signals for at least one of undercarriage regulation and control. The objective of this process is to superimpose on processed first signals which represent the acceleration of the vehicle body the low-frequency information absent from the signal of a vehicle body acceleration sensor by a circuit of simple design through a defined superimposition with the sensor signals corresponding to at least one of the spring deflection path and the spring deflection velocity. For that purpose, the sensor signals to be superimposed are processed in filter units whose transfer functions show a specific functional correlation.
