Mechanism of Electronic Suspension and Suspension Energy Capture (05-Jun-2009)
Electric cars and hybrid cars are becoming more popular. Current suspension on these vehicles and other vehicles employs a system that is virtually unchanged for decades. This invention describes a system of electronic suspension used for the purposes of: 1) Capturing the energy from the suspension of a vehicle to be stored and/or used by the vehicle; 2) The further use of the above to "dial-a-ride" - adjust the amount of regenerative feedback to make the ride smoother or harsher, and/or slightly optimize and/or decrease power use (electric and/or gas mileage); and 3) The further use of the above to "spoof" anyone looking at the dynamics of the car's ride and payload, to use a different ride/payload parameters. This could be used for security to hide or disguise suspension characteristics so that a vehicle could carry a heavy payload without appearing to be carrying such.

Benefits: This system would allow for possibly fewer moving parts and a higher MTBF for a suspension mechanism than traditional mechanical mechanisms. Also, this mechanism would allow for an alternative suspension mechanism based on electricity. With the advent of more electric vehicles, the may contribute to pursuit of this new technology. Another benefit is the availability of power from the undulation of the apparatus to be injected back into the system. The ability to adjust the "ride" by changing the algorithm/circuitry would also be an asset.
Description of how it works: The suspension mechanism is comprised of an internal "piston" (made of a rod or cylinder) with permanent magnets that is surrounded by on outside cylinder with a series of independent electromagnets. The cylinder would also contain a sensor that detects the position of the inside piston relative to the outside cylinder and the dynamic load placed on the mechanism. According to the amount of load and position of the two parts relative to each other, a circuit (or microprocessor) would adjust the amount of electricity applied...
