Abstract:

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.
