Adjustable damping system

An expandable and adjustable damping system in which a driver of an automotive vehicle having a plurality of wheels is able to manually adjust the suspension system to provide at least three ride characteristics, said adjustable damping system comprising:

• means for permitting said driver to select one of said at least three ride characteristics and generating a plurality of electrical control signals in response to said selection, said means for permitting said driver to select one of said at least three ride characteristics having a plurality of channels for propagating said electrical control signals;
• a plurality of distributed dampers each being operatively associated with one of said wheels of said automotive vehicle;
• and
• a plurality of control modules equal in number to said plurality of distributed dampers, each control module being operable to control a respective damper and electrically communicating with said respective damper and one of said channels, wherein at least one of said control modules comprises
• (a) a driver transistor electrically coupled to one of said dampers, said driver transistor coupled to one operable to selectively deliver current to said one damper to thereby cause the damping characteristics of said one damper to change,
• (b) a first gate transistor for controlling the current delivered to the base of said driver transistor in response to whether a first input from said one damper is substantially different from a first input from said means for generating a plurality of electrical control signals, and
• (c) a second gate transistor for controlling the current delivered to the base of said driver transistor in response to whether a second input from said one damper is substantially different than a second input from said means for generating a plurality of electrical control signals.
