Abstract
An exemplary power management system may include a power source and a transmission. The transmission may include a drive member and at least two shift ranges. The drive member may be driveably engaged with the power source. The power management system may also include a control system in communication with the power source and the transmission. The control system may be operative to cause a shift transition between the at least two shift ranges in response to a shift command. The control system may also be operative, during at least a portion of the shift transition, to modify at least one of a speed of the drive member and a speed of the power source based on at least one of a load condition of the power source, a speed of the power source, and the at least two shift ranges.
