Abstract: A system according to the present disclosure includes an engine speed module and a damper control module. The engine speed module is configured to determine a speed of an engine. The damper control module is configured to (i) fully engage a damper bypass clutch of a damper assembly to fully bypass a damper of the damper assembly when the engine is starting and the engine speed is less than a first speed, and (ii) partially engage the damper bypass clutch to partially bypass the damper when the engine speed is greater than or equal to the first speed. The engine is connected to a transmission through the damper when the damper bypass clutch is at least partially disengaged. The damper bypass clutch connects the engine and the transmission to one another independent of the damper when the damper bypass clutch is fully engaged.

Abstract: An anti-roll system for wheeled vehicles has one selective, unidirectionally lockable device per each independent suspension assembly having telescoping members connected between the sprung and unsprung masses that are free to extend or contract during vehicle operation which results in minimal lateral acceleration of the vehicle's sprung mass as when traveling down a straight roadway. The telescoping members include a piston that partially defines first and second chambers interconnected through valves to one another and to a common reservoir. The valves are activated, by a control system signal, when the sprung mass is subjected to a lateral acceleration which exceeds a preset threshold as when rounding a curve, blocking flow from one or the other of the first or second chambers so as to lock the outboard device, with respect to the curve, only against contraction and to lock the inboard device only against extension.
