Hydraulic clutch state diagnostic and control
Clutch engagement is preferably determined in accordance with monitored pressure conditions within a clutch control chamber. Clutch slip is monitored and information respecting clutch engagement inferred therefrom is stored for subsequent retrieval and use in a redundant slip based clutch engagement determination. Clutch slip is also monitored for information respecting clutch disengagement for use in a redundant slip based clutch disengagement determination.
