Реферат: An inching system (100) for a vehicle (10) having a hydrostatic transmission (16) and an engine (12) that drives the transmission (16). The transmission (16) has a pilot pressure port (40) with a pressure of hydraulic fluid at the pilot pressure port (40) controlling a level of power from the transmission (16), a beginning of draining of the hydraulic fluid from the pilot pressure port (40) defining an inching starting point (ISP). The system including a brake pedal (28); and an electrohydraulic valve (34) coupled to the pilot pressure port (40) of the transmission (16), the valve (34) being configured to drain the hydraulic fluid at the pilot pressure port (40). A sensor (104 or 106) is coupled to the pedal (28) to detect an input from the operator, the sensor (104 or 106) producing a signal (108) indicative of the input from the operator. A controller (102) receives the signal (108) and a speed of the engine (12). The controller (102) controlling the electrohydraulic valve (34) dependent upon the signal (108) and the engine (12) speed so that the inching starting point (ISP) is unchanged regardless of the speed of the engine (12).
