Construction machine with active ride control

A construction machine comprising:

• a variable displacement pump;
• a boom cylinder including a rod operable to extend and retract to move a boom of the construction machine, wherein a first chamber of the boom cylinder is configured to be supplied with fluid from the pump during rod extension while fluid is removed from a second chamber of the boom cylinder, and wherein the second chamber of the boom cylinder is configured to be supplied with fluid from the pump during rod retraction while fluid is removed from the first chamber of the boom cylinder;
• a valve between the boom cylinder and the pump, the valve configured to selectively control fluid flow to and from the boom cylinder;
• and
• an active ride control mode in which the valve between the boom cylinder and the pump is set to a predefined open position and disabled from switching from the predefined open position throughout operation in the active ride control mode, and the pump is configured to actively damp pressure fluctuations in the boom cylinder by variation of a displacement setting.
