Embodiments herein are directed to an emulator assembly. The assembly includes a housing with a cavity, a pedal arm, an elongated member, a carrier, an end plate and a compressible member. The pedal arm is at least partially received in the cavity and has a pedal pad on one end. The elongated member extends and couples to the pedal arm on one end and couples to a carrier on an opposite other end. The end plate is spaced apart from the carrier. The compressible member is positioned in the space between the carrier and the end plate. When the pedal pad is depressed, the elongated member moves the carrier in a direction towards the end plate which drives the carrier into the compressible member such that the compressible material compresses to generate a force feedback onto a foot positioned on the pedal pad.

An electronically controllable pneumatic brake system includes a service brake control module for controlling a first and a second service brake circuit, and a trailer control module with a trailer brake pressure connection point for connection to a trailer brake pressure coupling head. The trailer control module outputs a trailer brake pressure via the trailer brake pressure connection point. Upon a malfunction of the first and/or second service brake circuit, the first service brake pressure is controlled depending on the trailer brake pressure; and the second service brake pressure is controlled depending on the trailer brake pressure specified by the trailer control module; and/or the parking brake pressure is controlled directly or depending on the trailer brake pressure specified by the trailer control module. Upon a malfunction of the trailer control module, the trailer brake pressure is controlled depending on the first service brake pressure.

A method for controlling a brake system. The brake system includes an actuating device, a master brake cylinder, a brake circuit, a wheel brake, and a brake pressure generator. The brake pressure generator and the master brake cylinder are capable of being contacted, parallel to one another, to the brake circuit. A pressure generator control valve controls a first pressure medium connection between the brake pressure generator and the brake circuit. A brake circuit control valve controls a second pressure medium connection between the brake circuit and the master brake cylinder. The brake system is operated in an operating state during which the pressure generator control valve assumes an open position without a brake pressure prevailing in the brake circuit and without a buildup of brake pressure being carried out. During this operating state, the brake circuit control valve is controlled to assume an open position.
