Electronic control system for adjustable shock absorbers

摘要

An improved control system for electrically adjustable shock absorbers features a fault detector, a system-stop unit, and optional indicators and voltage-supply stabilization systems. The fault detector times the interval between an adjustment command from the operator and completion of the requested shock absorber adjustment, which is itself controlled by a feed-back system. If the adjustment is not completed within a predetermined period of time, the fault detector shuts down the control system via the system-stop unit and may illuminate the optional indicators. A stabilized power supply allows reliable use of the control system in hostile environments such as vehicles, and power-supply current limiting unit prevents electrical overloads in case of short-circuits or the like while facilitating detection of such electrical faults by the fault detector.
