An electro-hydraulic braking system includes a main casing. A hydraulic unit brake master cylinder is provided in the main casing. An outer end of a piston rod of the brake master cylinder is connected to an output top rod. Another end of the output top rod is provided with an input rod. The input rod is slidably connected in the main casing along only a length direction of the input rod, and another end of the input rod is provided with a push rod that is configured to transmit a brake pedal force. The main casing is further provided therein with a reset member configured to push the push rod away from the brake master cylinder to reset and a displacement sensor configured to sense a displacement of the push rod. The input rod and the output top rod include a spacing state and an abutment state.

An electro-pneumatic service and emergency braking control system is described, comprising: a switching device arranged to allow the connection of a first group of control and feedback signals from an emergency braking control module to an electro-pneumatic emergency braking module when a monitoring device determines the correct operation of the emergency braking control module and to allow the connection of a third group of control and feedback signals from the service braking control module to the electro-pneumatic emergency braking module when the monitoring device determines the incorrect operation of the emergency braking control module.

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.
