Abstract: In a method and a device for vehicle brake actuation, braking can be actuated as a function of a driver's default value, which can be set by the driver of the vehicle.

A limit value for the braking force is determined as a function of the driver's default value, and braking during execution of the automatic braking sequence is actuated independently of the driver in such a way that the modified braking force generated does not quantitatively exceed the limit value determined.
