Methods and systems are provided for adjusting a state of a driveline disconnect clutch (DCC) of a hybrid vehicle to either maximize fuel efficiency or reduce time to engine start, when the hybrid vehicle is being operated under engine-off conditions. In one embodiment, a controller of the vehicle estimates a modified driver demand power at an upcoming location on a route of the vehicle, and adjusts the DCC to a fully depressurized state to maximize the fuel efficiency when the modified driver demand power is lower, and pressurizes the DCC to a touch point to reduce the time to engine start when the modified driver demand power is higher. The modified driver demand power may be estimated by the controller by applying multiplication factors to a vehicle-weight-based baseline driver demand power, where the multiplication factors are calculated based on vehicle density of traffic and route characteristics.
