Abstract

A drive axle system (10) and a method for adapting a shift schedule of a drive axle system (10) based on an input is provided. The drive axle system (10) comprises a first shaft (18), a first axle assembly (14), a second axle assembly (16), a clutching device (28), a controller (55), and a plurality of sensors (75). The plurality of sensors (75) are in communication with the controller (55) for sensing at least one of an environmental condition and at least one operating condition the drive axle system (10). Based on the information from the plurality of sensors (75) the controller (55) selects one of a plurality of shift schedules and places the clutching device (28) in one of a first position and a second position.
