“…Furthermore, gear reduction can be implemented between the motor and the wheel satisfying high torque requirements at the wheel. 1,10 However, with such a drivetrain architecture, the torsional vibration of the side shafts need to be addressed exclusively, as mentioned above. This is simply because the torque command by the electric motors do not reach the wheel directly as in hub motors; they pass through the elastic half shafts.…”

“…Studies in literature that utilize electric motors for active safety can be classified from a vehicle drivetrain perspective: in-wheel motors at each corner, 3,[5][6][7][8] axle motors prior to the differential, and on-board motor drives with side shafts that are capable of commanding separate torques to right and left wheels. 1,4,10 These combinations are illustrated in Figure 1. The architecture that is observed in today's mass produced hybrid and/or electric vehicles is the first one: axle motor prior to the differential.…”

“…This communication involves torque commands and sensor signals (such as vehicle yaw rate and wheel speed) as well. It is reported in previous works 1,10 that time-varying delays of signals due to network communication between different modules could degrade the control performance of the entire system or even make the system unstable. Therefore, the motor-hydraulic brake torque blending strategy should mitigate the adverse effects of these signal delays.…”

“…Recently, there has been an increasing volume of research carried out on experimental setups and prototype vehicles to target performance improvement of vehicle's active safety features using electric motors. These studies consider motor braking/traction working either solely or in tandem with the hydraulic brake within an anti-lock braking system (ABS), [1][2][3][4] tractioncontrol system (TCS), 5,6 and/or vehicle-stability controller (VSC) [7][8][9] scheme. The general idea here is that by utilizing the electric motor actuation, some important performance criteria can be improved, such as a lower stopping distance during ABS braking, or better reference yaw rate tracking and lower vehicle sideslip angle during active VSC.…”

“…Rosenberger et al 1 analyzed a drivetrain topology named as ''on-board'' motor with side-shafts architecture. The rear-wheel brake torques commanded by a production ABS algorithm pass through the electric Orta Dogu Teknik Universitesi, Ankara, Turkey motor torque-control module first, so that the torque commands can be overwritten.…”

Recent electric vehicle studies in literature utilize electric motors within an anti-lock braking system, traction-control system, and/or vehicle-stability controller scheme. Electric motors are used as hub motors, on-board motors, or axle motors prior to the differential. This has led to the need for comparing these different drivetrain architectures with each other from a vehicle dynamics standpoint. With this background in place, using MATLAB simulations, these three drivetrain architectures are compared with each other in this study. In anti-lock braking system and vehicle-stability controller simulations, different control approaches are utilized to blend the electric motor torque with hydraulic brake torque; motor ABS, torque decomposition, and optimal slip-tracking control strategies. The results for the anti-lock braking system simulations can be summarized as follows: (1) Motor ABS strategy improves the stopping distance compared to the standard anti-lock braking system. (2) In case the motors are not solely capable of providing the required braking torque, torque decomposition strategy becomes a good solution. (3) Optimal slip-tracking control strategy improves the stopping distance remarkably compared to the standard anti-lock braking system, motor anti-lock braking system, and torque decomposition strategies for all architectures. The vehicle-stability controller simulation results can be summarized as follows: (1) higher affective wheel inertia of the on-board and hub motor architecture dictates a higher need of wheel torque in order to generate the tire force required for the desired yaw rate tracking. A higher level of torque causes a higher level of tire slip. (2) Optimal slip-tracking control strategy reduces the tire slip trends drastically and distributes the traction/braking action to each tire with the control-allocation algorithm specifying the reference slip values. This reduces reference tire slip-tracking error and reduces vehicle sideslip angle. (3) Tire slip trends are lower with the hub motor architecture, compared to the other architectures, due to more precise slip control.

Summary Vehicle technology advances and the world shifts towards E‐mobility, improving the performance of electric vehicles (EVs) and HEVs, which are becoming the prominent focus. One of the prime topics of EV development is increasing the driving range, which is the fundamental requirement. Apart from increasing the battery capacity, retrieving the wasted energy during conventional braking, also called as regenerative braking, is a hot topic. In this context, numerous control architectures and major braking approaches are considered to examine in this study in order to create an efficient regenerative braking system (RBS). This review article intends to provide an overview of major subsystems in the RBS such as motor control system and hydraulic braking system and how it affects the braking performance is also well discussed. Additionally, it complies with some of the recent research applications and systematically reviews the several braking control strategies implied. The prominent ones are fuzzy logic control, neural network, MPC, sliding mode, and adaptive control modelling approaches. These control strategies are used to enhance energy regeneration without affecting vehicle performance. Further, this article discusses the RBS design process and its calibration variables, such as speed of the vehicle and brake force estimation, which can be used to improve braking performance. Moreover, challenges on RBS improvements are effectively addressed, coupled with brief suggestions and discussions for the growth of future RBS development. Finally, this article will hopefully help the reader to critically analyse the working of RBS and encourage to design of an efficient RBS for electro‐mobility application. Highlights A holistic overview of the RBS control system architecture and its various control systems is reviewed. Various brake energy control strategies like Fuzzy, MPC, NN, SMC, Adaptive and learning‐based controls are critically evaluated. The discussion of necessary calibration process and its associated parameters are elucidated. Representation of real‐time design and development process of an efficient RBS in EV. Some of the prominent challenges faced during design and development of RBS and scope of future improvement is suggested.
