Actuator system and operating method for an actuator system

An actuator system for a service or parking brake, comprising:

• at least one electronically controlled electromotive actuator;
• and
• at least one electronic control unit, which is connected via at least one electric supply line to the actuator, and wherein the control unit is connected to at least one of one or a plurality of switches, senders, sensors S and electric actuating elements and comprises at least one microprocessor with implemented software for performing a regulation strategy for controlled or regulated electrical supply of the actuator, and wherein the actuator system is an electromechanically operated motor vehicle brake system comprising an electrically operated wheel brake for generating a defined application force between friction partners, wherein one or a plurality of items of information is/are supplied to the control unit as input variables, which enable the controller unit to determine the application force exerted by the electromotive actuator and to compare the determined application force with a specified minimum application force, and wherein the control unit emits at least one item of information, signal or similar for demanding a boosting actuation to peripheral systems, components and/or electronic control units, after the target-actual value comparison has shown that the determined application force set by the actuator is smaller than the specified minimum application force.
