The thesis has been completely developed at Center for Automotive Re-
search (CAR), The Ohio State University. The work has been focused on
modeling and sizing an Electro-Hydraulic Brake system (EHB) for a hy-
brid electric SUV equipped with axle motors. Within the target of this
study, an optimal regenerative braking strategy which utilizes a two-level
split of braking action has been investigated. The braking torque is first
distributed to front and rear axles in order to track the ideal brake force
distribution factor. Then, the regenerative braking strategy optimally splits
the torque between friction brakes and electric motors with the aim of max-
imizing energy recuperation. The regenerative braking strategy is applied
to the hybrid SUV vehicle simulator developed at CAR. Simulation results
show the effectiveness of the control strategy for different braking maneu-
vers. Finally, a comparative simulation study has been performed to assess
the performance of the strategy proposed against other two braking strate-
gies for three different driving cycles: urban (FUDS), highway (FHDS) and
aggressive (SMTP).
