Abstract: 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.

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.

Abstract: An underbody trim for the rear-end region of a motor vehicle conceals a rear exhaust muffler. For the purposes of cooling the rear exhaust muffler, an air inlet is provided in the underbody trim.
