Abstract: This paper proposes the use of Electromechanical Brakes (EMB) in combination with regenerative braking in PHEV so braking force can be distributed to front and rear axles according to an optimal curve instead of a linear line. Therefore, more braking force will be distributed to front axle, which will offer more kinetic energy for regenerative braking. Fuzzy logic control is used to allocate braking force between regenerative braking and electromechanical braking. The paper also studies antilock braking control of EMB to maintain safety and stability of a vehicle using sliding-mode control with switching gain fuzzy adjusting.

Keywords: plug-in HEVs; hybrid electric vehicles; EMB; electromechanical brakes; regenerative braking; frictional braking; sliding mode control; SMC; fuzzy logic; fuzzy control; braking force; vehicle design; antilock braking control; vehicle safety; vehicle stability.
