ABSTRACT:
A method of calibrating the control current startup threshold in a proportionally controlled drive system for a work vehicle is disclosed. To determine a current threshold value for use in the system a control current exhibiting a relatively low value is first applied to the system. Subsequently, the steps of repetitively increasing the control current to a control current start value at which system motion starts and decreasing the control current to a control current stop value at which system motion substantially stops are repetitively conducted. The resultant control current start values and control current stop values are stored in a memory. The stored control current start values and control current stop values are is then averaged to determine a control current threshold value for use in controlling the system.
