Methods and system for operating a hybrid vehicle in cruise control mode

摘要

Systems and methods for reducing driveline mode change busyness for a hybrid vehicle are presented. The systems and methods may delay a driveline mode change in response to a time since a change from a first desired vehicle speed to a second vehicle speed, or alternatively, driveline mode changes may be initiated in response to an estimated time to change from the first desired vehicle speed to the second desired vehicle speed.

1. A method for a controller, comprising:
during a closed-loop vehicle speed control mode, delaying a change in propulsion sources providing torque to a driveline of a vehicle or absorbing torque from the driveline via the controller in response to a determined amount of time since a change in a desired vehicle speed of the vehicle, where the propulsion sources include an engine of the vehicle and a driveline integrated starter generator (DISG) of the vehicle.
