Abstract:
1. A method for actuating a self-energizing brake having an electric actuator, comprising the acts of: amplifying an activation force applied by the electric actuator using a self-energizing device arranged between the actuator and brake lining; coupling the actuator to one of an open-loop and closed-loop control device configured to actuate the actuator; setting a position of the brake lining unit with a brake application unit actuated by an electromotive drive of the electric actuator; performing the closed-loop control process on the basis of braking system parameters for a vehicle controlled variable “braking or deceleration”, an actuator manipulated variable “current or actuator position”; compensating tolerance-conditioned braking force differences among the wheel brakes using a third controlled variable; and before activating the brake actuator, overcoming a venting play with an adjustment device, to remove the venting play as a fault source when beginning application of the brake by the brake actuator.
