In this study, we analyzed the regenerative braking characteristics of a fuel cell electric vehicle (FCEV) equipped with electronic wedge brakes (EWB) on the front wheels. To analyze the regenerative braking characteristics of the FCEV with EWB, a regenerative braking control algorithm was proposed for the regenerative braking and friction braking for front wheels and friction braking for rear wheels, and a powertrain model of an FCEV composed of a motor, fuel cells, and batteries and a MATLAB model of the control algorithm were developed. They were linked to the CarSim-RT (real time) model of the vehicle under study, whereas the braking hardware in the loop simulator (HILS) of the FCEV was built using the EWB hardware. This HILS was used to examine dynamic response of the regenerative motor torque and the EWB clamping force corresponding to the driver’s braking demand.
