ABSTRACT:
A control for determining the state of adjustment or misadjustment of a master friction clutch (14) in a vehicular automated mechanical transmission system (10). A system controller (24) receives input signals (26) indicative of the engaged or disengaged condition of the master clutch, the rotational speed of the transmission input shaft (IS) and the engaged or disengaged condition of the mechanical transmission (16). When the master clutch and the transmission both are disengaged, the rate of change of input shaft speed (dIS/dt) is compared to a predetermined reference value, and if the rate of deceleration of the input shaft speed is less than said reference value, significant master clutch misadjustment is determined and corrective action is initiated. Corrective action may include causing a display (48) to signal the operator that the master clutch is improperly adjusted and/or operating an input shaft brake (50) in a fault-tolerant mode.
