This paper presents a fundamental vehicle suspension system using real time computer control. This Computer Optimized Adaptive Suspension Technology (called COAST) consists of a microprocessor controlled, fully integrated, adaptive suspension system. COAST is capable of providing near optimum performance for any land surface vehicle in any environment and can be implemented in a relatively simple and cost effective manner. Each COAST suspension unit consists of a patented electronically controlled damping device and air spring. The damping device incorporates a novel valve that operates in conjunction with two solenoids to provide almost instant and infinitely variable compression and rebound damping forces that are predominately independent of piston velocity. In addition, each unit incorporates a novel position sensor that provides the required inputs to the microprocessor to optimally control the vehicle. Beyond the conventional load leveling capabilities of the air spring, the COAST utilization of a microprocessor will automatically adjust the height to accommodate varying road surfaces, forming an adaptive load leveling function.
