Device and method for braking a vehicle

A braking apparatus for a vehicle, having a first braking control device (6, 8, 9, 10, 15, 27) and a second braking control device (7, 16, 17, 18), in which case

• the vehicle can be braked both by operation of the first braking control device and by operation of the second braking control device, wherein
• in order to carry out an automatic emergency braking process for the vehicle, the first braking control device interacts with a first evaluation unit (19), and the second braking control device interacts with a second evaluation unit (21), and wherein
• the first evaluation unit (19) and the second evaluation unit (21) determine independently of one another whether the automatic emergency braking process should be carried out by operation of the respective braking control device, and the second evaluation unit (21) initiates the automatic emergency braking process when the first evaluation unit (19) and/or the first braking control device have/has a malfunction during operation,
• characterized
• in that the first evaluation unit (19) initiates the automatic emergency braking process only when the second evaluation unit (21) additionally determines that a predetermined additional initiation condition is satisfied.
