“…The initial investigation of the wedge brake concept is described in [1]. The concept was then further developed by eStop, which introduced the alpha-prototype, with the ability to realize the full braking force expected from a modern disc brake system [2,3]. At the center of the alpha prototype design is the brake heart, which realized the wedge braking principle, and the dual motor concept, which removed backlash in the transmission (Figure 1).…”

“…The cascaded controller concept for the single motor solution is structurally simpler than the control for the Beta prototype which had two motors. In the Beta solution, which was used in the references [2] and [3], a preload control had to be added to prevent backlash effects disturbing the control quality. Since the new prototype is designed such that the freeplay can be neglected over the lifetime of the brake, a preload control is no longer required and the controller has a pure cascaded structure, as depicted in Fig.…”

Siemens VDO is currently developing a brake-by-wire solution called the Electronic Wedge Brake (EWB). Earlier prototypes used a two-motor concept inside the brake actuator to drive the wedge. In this paper, a new prototype generation is presented where only one motor is needed. This is more efficient in terms of cost, and actuator weight, and also reduces the complexity of the control strategy. A state-space model is derived for the new actuator and two controller structures are explained. Simulations and experimental results from a roller test bench are shown.

In this work, laboratory tests have been carried out to investigate the influence of the presence of water and oil film, as well as the existence of wet dust between the disc and brake pads on the performance characteristics of conventional and wedge disc brakes are examined. The number of brake application and its influence on friction at dry and wet conditions are also investigated. The results indicated that the presence of a water layer between brake pads and disc led to increased friction coefficient and therefore increased the brake shoe factor. The presence of oil film between the friction surfaces lead to obvious reduction in the coefficient of friction. The influence of the presence of wet dust between the friction surfaces has a negligible influence on both conventional and wedge disc brakes.

“…The electromechanical brake (EMB) solution does not have the hydraulic part but there is an electric motor as actuator that provides the braking torque [12]- [14]. A particular EMB technology is known as wedge brake, where an electric motor controls the force on a wedge that pushes backward and forward the braking pads [15], [16]. In this paper, we consider a modified EHB solution first presented in [17]- [19]: an electromechanical actuator that pushes backward and forward the piston of a master cylinder connected to a traditional hydraulic brake.…”

In this paper, a cascade control architecture for a brake-by-wire system suitable for motor racing applications is described. The system is composed of an electromechanical actuator, i.e., an electric motor, a transmission, a master cylinder, and a traditional hydraulic brake (pipe and caliper). Starting from a control-oriented model, a cascade control is proposed. An inner-loop controls the position; an outer the pressure. The outer loop features an adaptation mechanism to cope with the intrinsic time-varying nonlinearity of the position–pressure relationship. The stability and robustness of the pressure loop are proven. Extensive experimental validation, conducted on an instrumented motorbike on a test circuit by a professional rider, shows the performance of the system
