Abstract: Among other things, methods and apparatus for automatically controlling hydraulic dampers are described. The apparatus can automatically sense the magnitude of at least one electrical input signal, automatically process each input signal through a microprocessor and associated software algorithm to determine an optimum damping rate, and automatically generate an electrical output signal corresponding to the optimum damping rate. The output signal is configured for communication with a hydraulic damper having means for automatically controlling the damping rate according to an electrical signal. Electrical input signals correspond to variables including engine speed, wheel speed, throttle position, vehicle operator position, and suspension position.
