Technology showcase active ride control system

In totally passive suspension systems, soft springs used to obtain a comfortable ride result in poor handling during cornering manoeuvres. If hard springs are used for good handling, ride quality surfers. This article describes the use of controlled hydraulic suspension systems to improve both ride and handling of on-and off-road vehicles. By incorporating inertial valve controls, multiple interconnected valves, and pressurized gas springs in the suspension system, a combination of good ride and handling is achieved without the large power consumption of a fully active suspension system. The mechanical features and operation of these recently developed suspension systems, and their application in a number of commercial, military, and agricultural vehicles are discussed.
