1. A driveline operating method, comprising:
adjusting a boost pressure supplied to a driveline disconnect clutch via a controller responsive to detecting a driveline disconnect clutch pressure error, wherein the driveline disconnect clutch pressure error is detected based on a difference between an expected driveline disconnect clutch pressure and an observed driveline disconnect clutch pressure, where adjusting the boost pressure includes adjusting the boost pressure according to a value of a weighting factor for the driveline disconnect clutch pressure error, the value of the weighting factor for the driveline disconnect clutch pressure error determined based on a function of a transmission fluid temperature and a magnitude of the driveline disconnect clutch pressure error.
