20150035375 | WAKE-UP DEVICE FOR A BRAKE SYSTEM COMPONENT OF A VEHICLE AND METHOD FOR EXCITING AT LEAST ONE BRAKE SYSTEM COMPONENT OF A VEHICLE - A wake-up device for a brake system component of a vehicle includes a magnet that is arranged to be set, via a transmission device, in rotational motion jointly with a shifting of a driver brake force transmission component, thereby effecting a relative motion between the magnet and an electrical conductor. The relative motion induces an induction voltage. An output device outputs the induction voltage or a wake-up signal generated based on the induction voltage to the brake system component, thereby controlling the brake system component to transition from a first energy use mode to a second energy use mode. A method includes controlling the brake system component to transition from the first energy use mode to the second energy use mode by outputting the induction voltage or wake-up signal generated as described above. | 02-05-2015 |
