A brake-by-wire braking system for a vehicle having at least two wheels which are able to be braked is described. The braking system comprises at least two brake actuator units, each of which can be associated with one of the wheels of the vehicle which are able to be braked. The braking system further comprises a brake actuation unit for actuation by the driver for braking, having at least one sensor for detecting an activation of the brake actuation unit by the driver, an acceleration actuation unit having at least one sensor for detecting the activation of the acceleration actuation unit by the driver, and at least one electronic control unit which is adapted to operate one or both of the brake actuator units in order to bring about a braking force at an associated wheel. The control unit is adapted to operate the brake actuator units on the basis of an activation of the acceleration activation unit in the event of a fault or failure of the brake actuation unit.

Brake-by-wire braking system

The disclosure relates to a braking device having an actuatable member, an electromagnetic coil having at least two coil windings, which can be energized independently of one another and which are each designed to generate a magnetic force for the actuatable member in an actuating direction in an energized state, and a resetting element, which exerts a force on the actuatable member in a resetting direction opposite to the actuating direction. The at least two coil windings and the resetting element are designed in such a way that the magnitude of the total magnetic force of all the coil windings exceeds the magnitude of the force of the resetting element only when all the coil windings are energized simultaneously. The disclosure further relates to a method for operating a braking device.
