ABSTRACT:
A control (42) and method for controlling an AMT system (10) is provided including sensing vehicle start from stop operation, determining a target engine speed value (A) based upon the operator setting of the throttle pedal (THL) and modulating the fuel supplied to the engine (FC) to cause the engine speed (N) to rapidly equal and then be maintained at said target engine speed value. The clutch (16) is engaged at a relatively slow first rate (106, 120), a relatively rapid second rate (126) or maintained at its current state of engagement (116) depending upon the value of engine speed (N) relative to the target value (A) and upon the amount and/or the rate of change of the amount of fuel supplied to the engine and/or the value of the difference between engine and input shaft speed.
