Abstract: A system and method configured to select a control configuration for a hydraulic drive assembly (206). The assembly (206) includes a controller (124) having at least one sensor and a processor (302). The controller (124) is configured to sense a feed pressure and a return pressure of a fluid within the hydraulic drive assembly (206) and a speed of a driven set of wheels (122) and a speed of an idle set of wheels (120). The driven set of wheels (120) are drivingly coupled to an engine (202), and the idle set of wheels (120) are drivingly coupled to the hydraulic drive assembly (206). The controller (124) is further configured to select a control configuration for the hydraulic drive assembly (206) based on a ratio between the feed pressure and the return pressure, and further based on a ratio between the speed of the driven set of wheels (122) and the speed of the idle set of wheels (120).

Abstract: A machine control system (34) may include an input receiving portion configured to receive torque inputs related to a hydrostatic transmission (22). The input receiving portion may also receive an operator request for actuating the hydrostatic transmission. The machine control system may also include a processor configured to determine a factor based at least in part on the torque inputs, for adjusting the operator request. The processor may also be configured to determine a command for actuating the hydrostatic transmission based on the adjusted operator request, such that a torque load to be exerted on a power source by the hydrostatic transmission is within a desired range. The machine control system may further include an output sending portion configured to send the command to the hydrostatic transmission.
