The Kinetic H2/CES system is a new advanced suspension system that combines the advantages of a passive hydraulic anti-roll system with added electronic intelligence through semi-active damping and adjustable roll stiffness. The Kinetic H2 anti-roll system replaces the standard dampers and anti-roll bars on the vehicle with actuators linked together by hydraulic lines. The removal of the antiroll bars leads to less weight and easier packaging of the suspension. The system concept includes the modal decoupling between the roll and the articulation stiffness of the vehicles. Improvements in tire force variation and related vehicle traction and stability are demonstrated in the article. Building further on this new suspension concept, mechatronic components are added. These include a small pump unit to adapt the roll stiffness and fast servovalves for real-time damping control and roll stiffness decoupling. To control these mechatronic components, sensors and a controller are added. Bringing together advanced mechanical and hydraulic systems with the intelligence of electronics leads to a new suspension concept that improves vehicle dynamics while using less energy compared with the active anti-roll systems available on the market today. In this paper, the authors explain how the CES and Kinetic. H2 systems are combined in one package, called the Kinetic. H2 CES suspension system. This interconnected passive-reactive system provides continuously controlled damping and high roll stiffness with reduced warp and articulation stiffness. Vertical tire loads are more equalized, resulting in significantly improved road traction and performance. The continuously controlled damping works with the skyhook principle for body control with added algorithms for wheel hop control, steering, braking and acceleration.
