  • HYDRAULIC BRAKING ENERGY UTILIZATION FOR EMERGENCY STEERING, BRAKING, CHARGING ACCUMULATOR(S), AND/OR WORK FUNCTIONS TO REDUCE OR PREVENT ENGINE FROM OVERSPEED, ASSIST ACCELERATION AND/OR UNLIMITED TOWING
    Publication number: 20230287907
    Abstract: A system and method configured to direct the braking energy from a high-pressure port at the motor side of a hydraulic circuit to emergency steering, braking, accumulator(s) charging, and/or various work functions. The system and method are also configured to return hydraulic fluid back to the same high-pressure port when the motor is running as a pump.
    Type: Application

    Inventors: Wenling Babbitt, W. E. Hoffner, III
  • FAN SPEED CONTROL SYSTEM FOR ENGINE COOLING
    Publication number: 20230235694
    Abstract: A control system that uses an algorithm to control the fan speed in a cooling system for an engine is disclosed. The algorithm is adapted to maintain a cooling medium at a set temperature instead of an operating temperature range of the cooling medium. The algorithm is also adapted to maintain a cooling medium at a set temperature and to build a cooling safety margin in response to an engine output torque percentage that is below an output torque percentage setpoint.
