Abstract
An electrically controllable pneumatic brake system has a front and a rear axle brake circuit, and a manually actuable brake signal transmitter which, upon actuation, outputs a first front brake control pressure and a first rear brake control pressure. A front axle brake pressure is produced based on a front axle braking demand pressure and a rear axle brake pressure is produced based on a rear braking demand pressure. A two-channel pressure modulator system is configured to receive a braking demand signal from an autonomous driving unit and, in response thereto, output the front and rear braking demand pressure, and is further configured to receive the first front and rear brake control pressure and, at least in an error situation, to output the front braking demand pressure depending on the first front brake control pressure and/or the rear braking demand pressure depending on the first rear brake control pressure.
