  • Inching system for a construction vehicle
    Patent number: 11685374
    Abstract: An inching system for a vehicle having a hydrostatic transmission and an engine that drives the transmission. The transmission has a pilot pressure port with a pressure of hydraulic fluid at the pilot pressure port controlling a level of power from the transmission, a beginning of draining of the hydraulic fluid from the pilot pressure port defining an inching starting point. The system includes a brake pedal and an electrohydraulic valve coupled to the pilot pressure port of the transmission, the valve being configured to drain the hydraulic fluid at the pilot pressure port. A sensor is coupled to the pedal to detect an input from the operator, the sensor producing a signal indicative of the input from the operator. A controller receives the signal and a speed of the engine. The controller controls the electrohydraulic valve dependent upon the signal and the engine speed so that the inching starting point is unchanged regardless of the speed of the engine.
