In general, this disclosure relates to a system and method of control for driveline actuators (DLAs) in the powertrain of an electric vehicle to perform shifting between two-wheel drive (2WD) and four-wheel drive (4WD) configurations. Sequential and overlapping shift process is used. The first disconnect is instructed by a vehicle control system to begin its shift, which takes approximately 100 milliseconds to complete. A short period of time after the first disconnect is instructed to begin its shift, but before it has completed the shift, the second disconnect is instructed to begin.
