Claim Text:
1. A brake module for a hydraulically braked towing vehicle, the towing vehicle being coupleable to a pneumatically braked trailer vehicle, the towing vehicle including a hydraulically actuated service brake having at least one brake master cylinder actuatable by a brake actuator to generate a hydraulic pressure in at least one wheel brake cylinder of at least one wheel of the towing vehicle, the at least one brake master cylinder having a hydraulic pressure line emanating therefrom and connected to at least one pressure sensor configured to detect the hydraulic pressure, the brake module comprising: an electropneumatic pressure regulating module having an electronic controller configured to receive pressure signals from the at least one pressure sensor and convert them into control pulses for electromagnetic control valves arranged in the electropneumatic pressure regulating module, the control valves being configured to connect (i) on an inlet side via a pneumatic supply pressure inlet to a compressed air reservoir and (ii) on an outlet side via a pneumatic control pressure outlet to a control pressure coupling head; a hydraulic connection to the hydraulic pressure line; a pneumatic connection to the compressed air reservoir; and a redundancy valve arrangement having a pneumatic outlet, the pneumatic outlet being configured to connect to the control pressure coupling head when an electrical or electronic component failure of at least one component relevant to operation of the brake module exists, the pneumatic outlet being configured to disconnect from the control pressure coupling head when no electrical or electronic component failure of the at least one component relevant to operation of the brake module exists; wherein the electropneumatic pressure regulating module and the redundancy valve arrangement are connected pneumatically in parallel o one another, the pneumatic outlet of the redundancy valve arrangement being exclusively connectable to the control pressure coupling head.
