“…On this basis, Yuan Ji et al [41] added the motor current slow sine experiment and obtained the kinetic friction and static friction curves. They found that the kinetic friction and static friction are asymmetrical with respect to the motor speed direction, and have a linear relationship with the load.…”

With the development of automobile electrification and intelligence, new requirements have been put forward for automotive braking technologies. Under this background, the One-box EHB (Electro-Hydraulic Braking system) brake-by-wire technology has emerged, which combines the electric booster and wheel-cylinder control module into one box and can realize vehicle stability and comfort functions such as service brake, pedal feel simulation, brake decoupling, failure backup, active braking, and wheel-cylinder pressure control. This article reviews the current research of key technologies of One-box EHB, including system architecture design and applications under high-level autonomous driving, master cylinder pressure control algorithm design, wheel-cylinder pressure control algorithm design, and electro-hydraulic composite braking control algorithm design. Finally, this article summarizes the current research status of One-box EHB key technologies and puts forward suggestions for future research directions.

Currently, the main solution for braking systems for underground electric trackless rubber-tired vehicles (UETRVs) is traditional hydraulic braking systems, which have the disadvantages of hydraulic pressure crawling, the risk of oil leakage and a high maintenance cost. An electro-mechanical-braking (EMB) system, as a type of novel brake-by-wire (BBW) system, can eliminate the above shortcomings and play a significant role in enhancing the intelligence level of the braking system in order to meet the motion control requirements of unmanned UETRVs. Among these requirements, the accurate control of clamping force is a key technology in controlling performance and the practical implementation of EMB systems. In order to achieve an adaptive clamping force control performance of an EMB system, an optimized fuzzy proportional-integral-differential (PID) controller is proposed, where the improved fuzzy algorithm is utilized to adaptively adjust the gain parameters of classic PID. In order to compensate for the deficiency of single-close-loop control and adjusting the brake gap automatically, a cascaded three-closed-loop control architecture with force/position switch technology is established, where a contact point detection method utilizing motor rotor angle displacement is proposed via experiments. The results of the simulation and experiments indicate that the clamping force response of the proposed multi-close-loop Variable Universe Fuzzy–PID (VUF-PID) controller is faster than the multi-closed-loop Fuzzy–PID and cascaded three-close-loop PID controllers. In addition, the chattering of braking force can be suppressed by 17%. This EMB system may rapidly and automatically finish the operation of the overall braking process, including gap elimination, clamping force tracking and gap recovery, which can obviously enhance the precision of the longitudinal motion control of UETRVs. It can thus serve as a BBW actuator of mine autonomous driving electric vehicles, especially in the stage of braking control.

“…The pressure control for the ABU system is relative mature as many control methods have been studied in this problems. [24][25][26][27] Limited by the structure of the HDU valves, brake pressure control during slip regulation lies in the on/off valve control under the cooperation of a plunger pump. However, the valve control research is typically based on a constant or a gradually changing pump backpressure, while little is known regarding the influence of a backpressure jitter.…”

Slip ratio control of current passenger vehicles is achieved by the traditional hydraulic distributed unit through its pump-valve structure, such as the antilock brake system module. This type of hardware largely limits the essential braking pressure regulating ability due to the pump’s jittering backpressure and valves’ poor controllability and further deteriorates the slip ratio control performance. This study proposes a novel electrohydraulic brake-by-wire system based on distributed boosters (Dbooster) as new slip ratio regulating actuators. The Dbooster’s dynamics are modeled and combined with slip braking dynamics into an integrated slip ratio control scheme. Based on this, a finite-time prescribed performance control method with a finite-time disturbance observer is designed to achieve constraint slip ratio regulating performance. Validations are conducted in simulation and hardware-in-the-loop tests. Furthermore, the results show that this study provides a practical solution for more accurate slip ratio regulation.
