“…It is because the electromagnetic field produced by eddy current influences the external magnetic field [12]. Hence, when rotor speed surpasses the critical speed, the eddy current brake torque can be expressed as where V, V , , , and represent the speed of brake disk, critical speed, scale factor, scale coefficient, and resistivity of brake disk [13][14][15].…”

“…All of the research work, such as mathematical model building, controls strategy designing, and the hardware in the loop testing bench constructing, discusses about the structure of Figure 1. As illustrated in Figure 1, the hybrid system is composed of an eddy current braking system (ECB) and an electro-hydraulic braking system (EHB); the main parts of the system are hybrid brake disk (1), electromagnetic coil (14), copper layer (17), permanent magnet generator (4-stator coil, 6-permanent magnet, and 16-generator shell), bracket (9), hydraulic piston (8), and friction pad (7). Since the brake disk material is different for ECB and EHB, the brake disk of EHB should have good wear resistance; however, the brake disk of ECB should have good conductivity.…”

This paper introduces an eddy current and electro-hydraulic hybrid brake system to solve problems such as wear, thermal failure, and slow response of traditional vehicle brake system. Mathematical model was built to calculate the torque of the eddy current brake system and hydraulic brake system and analyze the braking force distribution between two types of brake systems. A fuzzy controller on personal computer based on LabVIEW and Matlab was designed and a set of hardware in the loop system was constructed to validate and analyze the performance of the hybrid brake system. Through lots of experiments on dry and wet asphalt roads, the hybrid brake system achieves perfect performance on the experimental bench, the hybrid system reduces abrasion and temperature of the brake disk, response speed is enhanced obviously, fuzzy controller keeps high utilization coefficient due to the optimal slip ratio regulation, and the total brake time has a smaller decrease than traditional hydraulic brake system.

Eddy current brake (ECB) is an attractive contactless brake whereas it suffers from braking torque attenuation when the rotating speed increases. To stabilize the ECB's torque generation property, this paper introduces the concept of anti-magneto-motive force to develop the ECB model on the fundamental of magnetic circles. In the developed model, the eddy current demagnetization and the influence of temperature which make the braking torque attenuation are clearly presented. Using the developed model of ECB, the external and internal characteristics of the ECB are simulated through programming by MATLAB. To find the sensibility of the influences on ECB's torque generation stability, the stability indexes are defined and followed by a sensibility analysis on the internal parameters of an ECB. Finally, this paper indicates that (i) the stability of ECB's torque generating property could be enhanced by obtaining the optimal combination of "demagnetization speed point and the nominal maximum braking torque. " (ii) The most remarkable influencing factor on the shifting the demagnetization speed point of ECB was the thickness of the air-gap. (iii) The radius of pole shoe's cross section area and the distance from the pole shoe center to the rotation center are both the most significant influences on the nominal maximum braking torque.

“…Therefore, there are a lot of researches have been pursue d on the brake energy recycling, ranging from cooperative control [1][2][3][4] of regenerative brake and friction brake to the dynamic performance analysis in brake process [5][6][7]. However, the common trait of these existing hybrid electric vehicle brake control strategies is to use mechanical friction brake instead of electrical brake completely in the highintensity brake or high battery state of charge (SOC) and high battery voltage conditions in order to ensure the safety of the driving and charging.…”

For the sake of high-efficiency energy recycling and brake security for series-parallel hybrid electric vehicle, an integrated brake system with an electric consuming brake subsystem and advanced strategy is proposed. The specific structure of electric consuming brake subsystem is introduced. The brake processes in different brake conditions are analyzed. A brake control strategy relying on the brake condition is applied in the series-parallel hybrid electric vehicle. In view of the complexity and dynamic characteristics, a coupled whole vehicle model which combined the driveline model and the thermal management system model is proposed to study the energy flow and utilization in the different electrical brake processes. A simulation of the whole vehicle under an UDDS driving cycle is studied. According to the simulation result, the integrated brake system and control strategy are effective for the series-parallel hybrid electric vehicle. It not only can ensure the security of the vehicle driving and battery energy storage, but also can enhance the energy utilization and prolong the life of mechanical brake device in the brake process.
