MODELING AND CONTROL OF REGENERATIVE BRAKING IN A MULTI-MODE PLUG-IN HYBRID ELECTRIC VEHICLE

In this study, the authors used a systematic design methodology to design a regenerative braking system. The parallel brake systems were tested for their ability to deliver the optimum stopping distance and energy conserved while braking. The model of the vehicle was tested by utilizing this regenerative system in a model of a flexible plug-in hybrid electric vehicle that was modeled for a multi-mode plug-in hybrid vehicle using MATLAB and Simulink. In addition to improving the overall efficiency of the vehicle, regenerative braking also extends the life of the brake pads, since the energy recapture process reduces the use of friction brakes. Implementing regenerative braking requires a control algorithm to determine the usage of both hydraulic brakes and regenerative brakes, and optimizing energy conservation during braking while ensuring the safety and stability of the vehicle by considering the dynamics of braking. The model created in this project was tested for different city driving cycles and integrated all components of a multi-mode hybrid electric vehicle and regenerative braking system to obtain maximum energy restoration out of each brake
