The different sensors (1 to 5) monitor the dynamics of the vehicle and their read-outs are processed to determine the road conditions. The control system adjusts the suspension response to provide a comfortable ride, as well as improved vehicle handling and control. The reaction of the suspension changes are monitored to adjust the processor control.The system includes different filter frequencies to monitor the amplitudes for the different vibrations and to characterise the road effect. Accelerometers monitor the vertical movement of the vehicle and suspension
