摘要： A suspension system (30) for a mobile machine (12) is disclosed. The suspension system may have a seat (26) operatively connected to a cabin floor (28) of the mobile machine, a cylinder (44) connected between the seat and the cabin floor, and a spring (46) associated with the cylinder. The suspension system may also have at least one valve (52) configured to regulate fluid flow into and out of the cylinder, and a controller in communication with the at least one valve. The controller (54) may be configured to detect a failure condition of the suspension system. In response to detection of the failure condition, the controller may be further configured to cause the at least one valve to move to a default position at which fluid flow into and out of the cylinder is restricted by an amount that still allows fluid flow through the at least one valve.

摘要： A suspension system (30) for a mobile machine (12) is disclosed. The suspension system may have at least one sensor (68) configured to detect a performance parameter of the mobile machine, and a seat (26) operatively connected to a cabin floor (28) of the mobile machine. The suspension system may also have a cylinder (44) connected between the seat and the cabin floor, and a spring (46) associated with the cylinder. The suspension system may additionally have a controller (54) in communication with the at least one sensor. The controller may be configured to make a classification of an operation currently being performed by the mobile machine based on input from the at least one sensor, and to select for use in controlling movement of at least one of the cylinder and the spring one of a plurality of available maps stored in the memory of the controller based on the classification.
