Systems and methods for improving vehicle driveline operation

Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, pressures applied to two different clutches are coordinated such that a pressure boost phase of a driveline disconnect clutch does not occur at a same time as a pressure boost phase of a transmis...

Zusammenfassung:	Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, pressures applied to two different clutches are coordinated such that a pressure boost phase of a driveline disconnect clutch does not occur at a same time as a pressure boost phase of a transmission shifting clutch.
