Anti-stall system for open circuit systems

An anti-stall system, comprising:

• a work machine having an engine with an engine speed sensor, a hydraulic system, a command control, and a control system;
• the hydraulic system comprising a pump and a valve stack having a pressure sensor;
• the control system comprising:
• a proactive block configured to issue a first valve command to the hydraulic system based upon a first torque threshold being crossed, wherein the first torque threshold is below a current estimated torque load put on the engine based on operational parameters of the anti-stall system and operational variables of the work machine.

An anti-stall system, comprising:

• a work machine having an engine with an engine speed sensor, a hydraulic system, a command control, and a control system;
• the hydraulic system comprising a pump and a valve stack having a pressure sensor;
• the control system comprising:
• an engine set speed determination configured to set an engine speed at a current engine speed when an estimated torque load put on the engine based on operational variables of the work machine, crosses a torque threshold based on operational parameters of the anti-stall system,
• wherein the operational variables of the work machine comprise a total flow of the hydraulic system, a pressure of the hydraulic system, and a detected engine speed by the engine speed sensor, and the operational parameters of the anti-stall system comprise a torque curve stored in a database of the control system;
• and
• wherein the torque curve provides a predefined torque availability of the engine at a predefined engine speed.
