This paper presented a new type of integrated EHB system. The EHB consisted of a compact three-chamber structure of master cylinder and mode switching valves. This allowed for the easy implementation of three different modes: normal mode, failsafe mode and ABS mode. In normal mode, a PWM control method was proposed for pressure regulation that took into account overshoot and hysteresis. To provide a favorable pedal feeling, a pedal stroke simulator was designed and integrated with the master cylinder. The failsafe and ABS modes were verified and the performance of the EHB in the three modes was evaluated using co-simulation and a bench test.
