Work vehicle including start-up control current calibration mechanism for proportional control systems |
摘要 |
A method of calibrating the control current start-up threshold in a proportionally controlled drive system (11) for a work vehicle (10) is disclosed. To determine a current threshold value for use in the system (11) a control current (IC1/IC2) 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 (117). The stored control current start values and control current stop values are then averaged to determine a control current threshold value for use in controlling the system. |
