Title: Apparatus and method for coupling a disconnectable stabilizer bar system

Abstract: Improvements for a vehicle stabilizer bar assembly having a pair of stabilizer bar members that are selectively uncoupled via a clutch assembly to provide a vehicle with improved traction. A first improvement concerns a reserve powering apparatus for powering the clutch assembly in the event of an electrical failure that prevents the vehicle power source from transmitting electrical power to the clutch assembly. A second improvement concerns a speed sensing apparatus for inhibiting the operation of the stabilizer bar assembly in a disengaged condition if the speed of the vehicle is greater than or equal to a predetermined speed threshold. A third improvement concerns a logic for controlling the engagement and disengagement of a pair of stabilizer bar assemblies.
