Active automotive suspension systems have been under development for a number of years with recent introductions of various versions. A suspension system can be considered 'active' when an outside power source is used to alter its characteristics, and these systems can be placed into one of three (3) different categories: semiactive damping, fully active, and low frequency active. A regenerative pump concept can minimize the power requirement for the low frequency active system. It utilizes four (4) independent variable displacement pump/motor combinations on a common shaft to actuate each individual suspension unit. This paper overviews the system configuration, describes the power and energy-saving features of the system, and discusses possible pump configurations and control strategies.
