“…The slider beam, which enables forward and back movements, will initiate the inner wedges to move tangential to the slider beam movement, hence clamping the brake disc. The FIXEWB dynamic model is derived as Equation (1) 20 and the brake torque calculations used in this study are as Equations (2)-(4) in Rahman et al, 10 while the actuator mathematical model (DC motor) is as the equation derived by Roberts et al 13 :…”

“…Along with IBS, several braking systems have been invented, such as the electro-hydraulic brake (EHB), 1,2 electro pneumatic brake (EPB), 3 electromechanical brake (EMB), 4,5 and lately the electronic wedge brake (EWB). 6–12 Among them, the EWB is the possible platform and effective to be used as an IBS because of its ability to provide higher braking torque and faster response by using the standard 12 V power supplies system. 11 Furthermore, the EWB system is a class of hydraulic free braking system, so that the problems with leakage, vaporization of oil as in the hydraulic brake, can be totally avoided, and thus it is easier to control and there is less complexity in the system model compared with the electro-hydraulic/pneumatic brake system.…”

This paper presents an investigation into the performance of a fixed caliper based electronic wedge brake (FIXEWB) in a vehicle braking system. Two techniques were used as assessment methods, which are simulation via MATLAB Simulink software and experimental study through hardware-in-the-loop-simulation (HILS). In the simulation study, the vehicle braking system was simulated by using a validated quarter vehicle traction model with a validated FIXEWB model as the brake actuator. A proportional-integral-derivative controller was utilized as the brake torque control, whereas proportional-integral and proportional controllers were used as the position and speed control of the actuator, respectively. To study the effectiveness of the FIXEWB, the response of the vehicle using the FIXEWB is compared with the responses of a vehicle using a conventional hydraulic brake. A dynamic test, namely braking in the sudden braking at constant speeds of 40 and 60 km/h was then used as the testing method. The simulation results show that the usage of the FIXEWB with an appropriate control strategy produces similar behavior to that of a hydraulic brake in terms of the produced desired braking torque but with faster time response. To study the performance of the FIXEWB when implemented on a real vehicle, an experimental rig using HILS was designed and the results are analyzed using the same dynamic tests. The performance areas evaluated are vehicle body speed, wheel speed, tire longitudinal slip, and the stopping distance experienced by the vehicle. The outcomes from this study can be considered in the design optimization of an antilock braking system control in a real car in the future.

“…Aside from that, a number of researchers continue to use DC motors in the EWB design by incorporating additional features, such as a pushrod non-self-locking screw to activate push and release [10], a roller bearing as the abutment [9], and a worm gearing system to activate the wedge mechanism [22,29]. Based on the results of the conducted journal.ump.edu.my/ijame ◄ experiments, these extra features are very effective at preventing wedge mechanism jamming; consequently, they have become a common feature of the EWB design [19][20][21]23,[28][29][30].…”

This paper describes a new design of an electronic wedge brake (EWB) system called the Cone Wedge Shape Based Electronic Wedge Brake (CW-EWB). The CW-EWB brake is made up of two cone wedges, one female and one male, stacked on top of each other. The CW-EWB is powered by the linear movement of a roller screw caused by the rotation of an electric motor through the roller screw, which causes the lower wedge to move tangentially to the disc brake, creating braking torque as the wheel rotates. A dynamic model of the CW-EWB that creates braking torque was built in this study, utilising a physical parametric estimate method. A torque tracking controller based on the proportional integral derivative (PID) control scheme is presented to ensure the CW-EWB model performs properly. The resulting mathematical model and control method were then experimentally tested using a braking test rig outfitted with multiple sensors and input-output (IO) devices. The performance of the brake mechanism is analysed in terms of actuator voltage, current, wedge position, wheel speed, and brake torque. Consequently, comparisons are made between experimental outcomes and simulated model responses. There are comparable trends between simulation results and experimental data, with an acceptable level of error.

“…It was reported that the controller focusing on controlling the variable ratio by using hydraulic actuation (Wang et al, 2011;Cholis et al, 2015;Jinchun and Changzhou, 2008;Han et al, 2006). Due to the drawbacks of hydraulic system such as leakage and vaporisation of hydraulic fluid, it is difficult to accurately control the system (Abd Rahman, 2013;Aparow et al, 2014;Ahmad et al, 2015). A new class of free hydraulic CVT system is proposed which replacing the internal hydraulic circuit with an electronic actuation system.…”

Vehicle transmission system transfers torque and speed from the power source to drive wheels. Continuously variable transmission (CVT) system offers smooth ratio transition where it improves acceleration performance and reduces fuel consumption. Currently, most of the CVT system is actuated by the internal hydraulic circuit where compressibility of oil introduces non-linearity to the system causing difficulty in controlling CVT response. Therefore, a new free-hydraulic CVT system is developed to overcome the shortcomings in existing CVT. The proposed CVT system is designed based on belt-driven type which consists of two sets of variable pulley. Each set of variable pulleys is actuated by an electric motor using slider crank mechanism. The mathematical modelling of CVT mechanism is developed by using Lagrange formulation. The results from this study show that the simulation model of CVT mechanism can produce good performance behaviour in following desired radius position of the real CVT mechanism.
