Abstract
A braking method for a vehicle is proposed as a safety measure and replacement function if the brake system fails, in particular the X-by-wire brake system of a motor vehicle, in which the vehicle is braked with the help of the transmission by a defined engagement of frictional shift elements until the vehicle comes to rest, such that the combination of frictional shift elements actuated when the vehicle's working brake system fails does not correspond to the shift logic of a gear during normal driving operation of the vehicle.
