Functional design of a parallel pneumatic drive train for regenerative braking

This paper presents the conceptual design and development of a Pneumatic Regenerative Braking System (PRBS) which specifically targets small to medium sized vehicles powered by petroleum fuels. The idea revolves around recovering energy that is normally lost during the braking process and putting it to better use, such as helping the vehicle accelerate. By lessening the burden of an Internal Combustion Engine (ICE), it is hoped that air pollution can be controlled. A Hardware-in-the-Loop test rig was also designed to simulate and test the concept. Analysis of the test results validates the concept and promises a feasible hybrid technology alternative.
