“…In the current research on brake energy recovery at home and abroad, according to whether the brake pedal force is decoupled from the hydraulic braking force or not, the brake energy recovery system can be categorized into iterative regenerative braking system (RBS) and collaborative regenerative braking system (CRBS), and by comparing these two types of regenerative braking systems, a more e cient and concise brake energy recovery system is selected [11] .…”

Aiming at the problem that underground mine cars need to brake frequently in the mine and cause a large amount of energy waste, we analyzed the working characteristics of underground mine cars and put forward the idea of energy consumption optimization based on braking energy recovery; we designed a braking energy recovery device suitable for underground mine cars; we calculated the comparison of energy consumption before and after installing the energy recovery system in mine car locomotives through mathematical modeling, and estimated the energy recovery benefit in the operating conditions of the underground mines. The results show that in the operation process, the energy recovery system can be used to recover energy from the brakes. The results show that the braking energy recovery system can successfully recover more than 50% of the braking energy during operation, increase the range of the mine car motorcar by about 20%, significantly improve the energy utilization efficiency of the coal mine tram, and reduce the system energy consumption and CO2 emissions.

“…Most of the regenerative brake systems of EV are composed of electrical systems, such as motor, power inverters, and battery, but Ma proposed a new combined brake system structure, including power coordinate module, electro-hydraulic brake system, and hydraulic regenerative braking system, and designed a simple fuzzy control method to coordinate the high-pressure and low-pressure accumulators. The simulation found that the liquid capacity and initial SOC of the energy storage accumulator are the key factors affecting the energy recovery efficiency, and the initial braking velocity is the determining factor of the total recovery energy [102]. A conventional regenerative brake system needs to store the recovered energy in a energy storage device, such as battery or super capacitor, and then the storage device supplies the electric energy to other electric equipment.…”

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)...

“…Laaleh Durali [8] designed a braking system for a cam-driven mechanism that maximizes the characteristics of the motor torque by combining electrical and hydraulic components, which can be fitted to each wheel and can be independently controlled for individual wheels, resulting in better stability of the vehicle during rapid acceleration or emergency braking. Ma [9] proposed a novel structure of a combined braking system based on regenerative braking energy, built a simulation model through Simulink to analyze the dynamic parameters such as the initial braking speed and the maximum braking pressure of the vehicle, and concluded that the initial braking speed of the vehicle is the key to affecting the total efficiency of braking energy recovery. The precise control of the hydraulic pressure of the wheel cylinder is a key technology of the linear control system.…”

With the development of the brake-by-wire system, more and more advanced driver assistance systems have been applied to automobiles. The brake-by-wire system can collect the driver’s braking intention through the displacement sensor and thus realize accurate braking by the motor. Based on the brake-by-wire system, we design an algorithm that can realize the vehicle Comfort Stop Technology (CST) in this paper. The CST can control the drop and rise of brake fluid pressure during the braking stop of the vehicle, and therefore reduce the sharp feeling of front and back pitching during the braking stop. Finally, through real car verification, the functional algorithm designed in this paper can improve the nodding feeling of the vehicle by reducing the deceleration of the vehicle during braking.
