Abstract
A hydraulic system includes a hydraulic mechanism that includes a first and a second chamber. The hydraulic system includes a control valve fluidly connected to the first chamber and a pressure sensor that is configured to measure the fluid pressure in the first chamber. The hydraulic system includes a processing unit connected to the control valve. The processing unit is configured to control a hydraulic fluid flow rate to and from the first chamber of the hydraulic mechanism via the control valve to provide a shock absorption response. The hydraulic fluid flow rate is based at least in part on a pressure measurement received from the pressure sensor. The shock absorption response is based on a simulated hydraulic accumulator.
