DIRECTION SWITCHING OF HYDROSTATIC DRIVE WORK MACHINE

PROBLEM TO BE SOLVED: To provide a direction switching means for a hydrostatic drive work machine. SOLUTION: A method of performing direction switching event in the hydrostatic drive work machine and the hydrostatic drive work machine are provided. This method includes a step of adjusting the pump displacement of a variable displacement pump 14 coupled with an engine 12 and a hydraulic motor 16 of the work machine at a rate at least partially based on one or both of a predetermined acceleration limit and a predetermined jerk limit of the work machine. The work machine is provided with an electronic control module 20 having a computer readable medium with directional shifting control algorithm recorded thereon. The control algorithm includes a means for adjusting pump displacement in a hydrostatic drive of the work machine at a rate at least partially based on one or both of the predetermined acceleration limit and the predetermined jerk limit of the work machine.
