This paper reviews and summarizes the development, key technologies, and application of brake-by-wire (BBW) actuators. BBW is the technology orientation of future vehicle brake system. The main feature of BBW is to replace some of the mechanical and hydraulic components of traditional brake system with electronic control components, and use cables and wires to transmit energy and signals. BBW actuators have outstanding advantages, such as fast response, accurate control, and compact structure. They are easy to integrate with active safety functions and they are easily matched with the regenerative braking systems of electric vehicle. First, this paper summarizes the classification, characteristics, performance, and architecture of BBW actuators. Subsequently, the braking process regulation of vehicle is considered to be the main target, which is summarized from two aspects of actuator regulation and braking force distribution. The state estimation algorithm and control algorithm applied to these actuators are summarized and analyzed, and the development trend, challenges, and schemes of the braking force distribution are proposed. The development and research trend of braking force match strategies between the regenerative brake system and BBW system are also analyzed and summarized. The further electrification and intelligence of vehicle demand BBW's braking force control method and distribution method must have higher control accuracy, stronger robustness, and wider adaptability, and the effects on braking comfort and handling stability must be further discussed.Actuators 2020, 9, 15 2 of 24 new features [2,3]. The additional functions, such as ABS and ESP, require additional devices, such as high-speed solenoid valves, oil return pumps, and return lines. Therefore, the structure of hydraulic brake system is becoming increasingly complex, and the maintenance is also becoming more and more difficult [4,5]. At present, new energy vehicles, such as electric vehicles (EV), hybrid electric vehicles (HEV), and fuel cell electric vehicles (FCEV), are developing rapidly and are highly concerned by major automotive manufacturers. However, most electric vehicles still use hydraulic brake system. On the one hand, the electric vehicles cannot use vacuum boosters to provide auxiliary force. The electric hydraulic pump must first be used to increase the hydraulic pressure, and then delivers the high pressure to each wheel. The electric energy needs to be converted and then transmitted multiple times in this process, so the energy utilization efficiency is not high, and there is the potential danger of brake fluid leakage. On the other hand, the hydraulic brake system cannot accurately and independently regulate the braking force, so it cannot be well matched with the regenerative brake system of EV and HEV [6].Actuators 2020, 9, 15 2 of 24 hydraulic brake system is becoming increasingly complex, and the maintenance is also becoming more and more difficult [4,5]. At present, new energy vehicles, such as electric vehicles (EV)...

Abstract:We have developed a battery hardware-in-the-loop (HIL) setup, which can facilitate the process of design and evaluation of power management controllers for hybrid electric vehicles (HEVs) in a novel cost-and time-effective manner. Since the dynamics of the battery greatly affects the HEV power management controller design, and because such dynamic behavior is difficult to model, physical batteries and a real-time battery cycler are included in the setup for greater simulation fidelity. The setup employs a scaled-down battery HIL that reduces the development and testing efforts, while, by using Buckingham's Pi Theorem, maintains the required flexibility and enhances the control loop fidelity.In this article, the application of the setup in integrating the development and the evaluation processes is shown. First, the setup is used for parameter identification of a simple control-oriented model of the battery, which is then used in the power management controller design. Finally, the real-time performance of the designed controller, programmed into an electronic control unit (ECU), is tested with the same setup in the realistic control environment. Furthermore, the battery HIL simulation results show that the designed controller is able to accurately capture the dynamics of the real system, by which the assumptions made in its design process can be confidently justified.
