Abstract:
A control system for controlling an axle clutch between two half-axles in a motor vehicle is provided. The control system includes two solenoids and a pressure sensor in communication with a controller and a valve assembly. One of the solenoids provides a flow of fluid to engage the axle clutch. The valve assembly cooperates with another of the solenoids to disengage the axle clutch under certain conditions.
