Enhanced computer optimized adaptive suspension system and method

A method of controlling one or more suspension control units, each suspension control unit comprising a body coupled to a damper shaft coupled to a wheel, and at least one sensor generating signals, the at least one sensor selected from the group of sensors consisting of sensors sensing damper shaft position, sensors sensing the degree of wheel turning, and sensors sensing brake application and sensing speed, the method comprising:

• preconditioning the signals provided by the at least one sensor to generate a plurality of preconditioned signals;
• processing the preconditioned signals to determine at least one independent parameter for each suspension control unit;
• determining, in response to the at least one independent parameter, a desired independent response for each of a plurality of states of motion for each of the control units;
• generating compression and rebound control signals for each of the suspension control units based on the desired independent response corresponding to each control unit;
• modifying the compression and rebound control signals to account for vehicle loading conditions;
• and
• providing the modified control signals to their corresponding control units, for causing the damper shaft of each control unit to apply damping force to its coupled wheel.
