Abstract

A method and system for controlling a brake for motor vehicles. The present invention relates to a method as well as a system for controlling a brake for motor vehicles, which can be electromechanically actuated by means of an actuator, consisting of an electric motor as well as a drive mechanism positioned downstream of the electric motor. In order to be able to increase motor speed under certain operating conditions, i.e. according to demand, without reducing the available torque, the invention provides for the slope of the speed-torque characteristic curve of the electric motor (4) to be modified by weakening components of the electromagnetic field of said electric motor (4), which affect the dynamics of same, in such a way that a higher speed (&ohgr;′1) is obtained at the same torque (M1).
