ABSTRACT:
The present invention discloses a hydraulic cylinder suspension method for actively controlling shock-induced vibration when a hydraulic cylinder in a construction vehicle makes a sudden stop, the method comprising the steps of: determining whether the hydraulic cylinder makes a sudden stop; receiving a pressure signal; determining an operational direction of the hydraulic cylinder during a sudden stop of the hydraulic cylinder; and supplying hydraulic fluid to large and small chambers of the hydraulic cylinder or returning to a tank.
