Abstract

La invención se refiere a un método para operar un sistema de frenos de vehículo, que comprende un servofreno y un dispositivo de control de deslizamiento electrónico, que se utiliza como un nivel de reserva en el caso de un mal funcionamiento del servofreno. De acuerdo con la invención, si se detecta un mal funcionamiento del servofreno, se determina la posición de un pedal de acelerador y, siempre que se libere el pedal de acelerador, se acumula una presión inicial predefinida en una cámara de presión de un cilindro de freno maestro del sistema de frenos de vehículo con la ayuda del dispositivo de control de deslizamiento, provocando de esta manera una desaceleración del vehículo. La invención se refiere además a una unidad de control que se configura para ejecutar el método, y un vehículo que tiene un sistema de frenos de vehículo y una unidad de control de acuerdo con la invención.
