Patent ID: 8348350

Claim:
An electromechanically controlled braking system, for multi-axle road vehicles, comprising for each axle a pneumatic braking module ( 6 ) connected to a feed reservoir ( 8 ) containing brake-actuating gas and comprising brake actuation elements ( 7 ), the braking system comprising: a manual element ( 13 ) with two operating stages corresponding to a service braking mode and to an emergency braking mode, which is manually actuated to initiate a braking process and a position of the manual element ( 13 ) determines an intensity of the braking required; a proportional solenoid valve (EVP 9 ) for each braking module ( 6 ) which, when the manual element ( 13 ) is actuated, receives at least one of an electric braking command and a pneumatic braking command, and an opening of the proportional solenoid valve (EVP 9 ), which is proportional to the at least one of the electric and the pneumatic braking commands received, brings the brake actuation elements ( 7 ) into communication with the feed reservoir ( 8 ) so as to produce a required braking force; at least one deceleration control unit (UCD 12 ), which receives information of the position of the manual element ( 13 ) and, from that received information when the manual element ( 13 ) has been actuated, generates the electric braking command for controlling opening of the proportional solenoid valves (EVP 9 ) electrically; an electric control line ( 11 ) for each braking module ( 6 ), which forms an electric connection between the deceleration control unit (UCD 12 ) and each of the proportional solenoid valves (EVP 9 ) and enables transmission of the electric braking command; a pneumatic control line ( 10 ), which forms a pneumatic connection between the manual element ( 13 ) and the proportional solenoid valves (EVP 9 ) and enables transmission of the pneumatic braking command generated by the manual element ( 13 ), only during the emergency braking mode; and a deceleration control unit output inhibitor (ISU 33 ), which enables at least one output of the deceleration control unit (UCD 12 ) to be blocked when at least one of the manual element ( 13 ) is in a rest position and in the event of a safety braking command ( 35 ).
