“…Eiji Nakamura [7] has developed an EHB system named "Electronically Controlled Brake System" (ECB). The ECB they presented integrates brake control functions such as the cooperative control between the regenerative brakes of the front/rear motors and the hydraulic brakes, ABS (Antilock Brake System), VSC (Vehicle Stability Control), TRC (Traction Control), etc.…”

A new X-by-wire system named Electronic Hydraulic Brake (EHB) System is designed in this paper, which can establish for smooth control of wheel cylinder hydraulic pressure. In this new EHB system, the electronic unit can supply flexible control, and at the same time, the hydraulic unit provides high power needed by the brake system. This brake system has high potential to add functional enhancements with proper modifications of software, such as ABS, VSC, TRC and ESP. This brake system is expected to become the core technology for further improving the vehicle stability.

“…Most manufactured electrified vehicles, including the Toyota Prius, Nissan Leaf and Tesla Model S, are now equipped with regenerative braking. [9][10][11] Control strategies have also been widely investigated by researchers around the world. [12][13][14] However, the introduction of regenerative braking into deceleration operations not only provides great potential for improving the vehicle's energy efficiency but also poses tremendous challenges to existing brake theories and control methods.…”

Regenerative braking provided by an electric powertrain is very different from conventional friction braking with respect to the system dynamics. During regenerative decelerations, the powertrain backlash and flexibility excite driveline oscillations, causing the vehicle driveability and the blended brake performance to deteriorate. In this article, system models, including a powertrain model with non-linear backlash and flexibility, and a hydraulic brake system model, are developed. The effects of the powertrain backlash and the flexibility on the vehicle driveability during regenerative deceleration are analysed. To improve the driveability and the blended braking performance of an electric vehicle further, a mode-switching-based active control algorithm with a hierarchical architecture is developed providing compensation for the backlash and the flexibility. The proposed control algorithms are simulated and compared with the baseline strategy under the regeneration braking process. The simulation results show that the vehicle driveability and the blended braking performance can be significantly enhanced by the developed active control algorithm.

“…They are able to eliminate the large vacuum booster found in conventional systems, which helps to simplify production of right-and left-hand drive vehicle variants. When compared to conventional braking systems, EMB systems offer increased flexibility for components placement by totally eliminating the hydraulic system (Nakamura et al, 2002). Figure 2 shows the comparison of EMB and EHB (Electro-Hydraulic Brake) systems.…”
