An electropneumatic trailer control module () includes a trailer control connection () configured to deliver a trailer control pressure (pTC), an electropneumatic trailer control valve arrangement () configured to receive a supply pressure (pS) and to provide the trailer control pressure (pTC) and an electronic trailer control connection () for providing trailer braking control signals (STB) such that the trailer control pressure (pTC) can be modulated. The electropneumatic trailer control module () is characterized by a protection connection () for receiving a pneumatic protection pressure (pPR), and a tractor protection unit () configured to switch between a supply state () and a protection state (). The invention further relates to an electropneumatic braking system (), a vehicle () and a method () for controlling a trailer supply function of an electropneumatic braking system ().

Electropneumatic trailer control module

A control valve for applying a spring-loaded brake pressure to spring-loaded parts of a rear-axle wheel brake is pneumatically activated as a function of a parking-brake braking demand and a service-brake braking demand. A first control chamber is connected via a first control piston to a control arrangement in the control valve. During an adjustment of the first control chamber via the service-brake control pressure, the spring-loaded brake pressure at the working output is a function of the service-brake control pressure or of the parking-brake control pressure. The first control piston is connected to a third control chamber, wherein the pressure in the first control chamber acts on the first control piston in one direction, and the pressure in the third control chamber acts on the first control piston in the opposite direction. The first control chamber is selectively connectable to the third control chamber via a switchable bypass valve.
