Abstract:
1. An electric drive module for driving a pair of wheels in a vehicle, comprising: a pair of axleshafts adapted for connection to the pair of wheels; an electric motor having a rotor shaft; a differential unit connected to said pair of axleshafts; a geared reduction unit driven by said rotor shaft; a disconnect mechanism for selectively coupling and uncoupling said geared reduction unit and said differential unit, said disconnect mechanism including a clutch and a power-operated actuator for actuating said clutch, wherein said clutch is operably disposed between said geared reduction unit and said differential unit and is operable in a first mode to establish a drive connection between said geared reduction unit and said differential unit and in a second mode to release said drive connection between said geared reduction unit and said differential unit, and wherein said power-operated actuator is operable for shifting said clutch between its first and second modes; and a disconnect control module for controlling actuation of said power-operated actuation in response to a sensor signal associated with an operational characteristic of the vehicle, wherein said sensor signal is an ABS status signal, and wherein said disconnect control module commands said power-operated actuator to shift said clutch into its first mode when said ABS status signal indicates an inactive status and commands said power-operated actuator to shift said clutch into its second mode when said ABS status signal indicates an active status.
