A compressed air operable wheeled trailer braking system includes an electronic braking control unit (ECU) 26 having an electronically operable control valve 22 which derives suitably proportioned load and vehicle speed dependent service brake pressure for brake chambers 23, 24, 25 of the trailer wheeled. The ECU 26 has a data memory storing specific braking parameters normally installed therein prior to commissioning the trailer and the trailer has a further diagnostic ECU 27 responsive to vehicle operational sensors, the further ECU also having memory capacity wherein said specific braking parameters are stored via a communication link consequent upon installation thereof to the braking ECU and means which recognizes installation of a replacement braking control unit 26 to install said parameters herein from said further ECU.
A vehicle braking system including means operable to produce a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a parameterisable electronic braking control unit with a main configuration memory for storing braking parameters particular to the vehicle for control of vehicle brake force according to vehicle loading wherein said system includes a further electronic storage memory wherein said braking parameters particular to the vehicle are permanently retainable and means operable to effect entry of said parameters from said further memory to the main configuration memory of an unparamneterised electronic braking control unit.
A trailer vehicle braking system including means operable to produce a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a main parameterisable electronic braking control unit with a main configuration memory for storing braking parameters particular to the vehicle for control of vehicle brake force according to vehicle loading a further electronic control unit including a configuration memory storing parameters particular to management of the vehicle and also a further electronic storage memory wherein said braking parameters particular to the vehicle are also permanently retainable and means operable to effect entry of said parameters from said further electronic memory to the main configuration memory of another unparameterised electronic braking control unit when substituted for said main unit.
A trailer vehicle braking system including means operable to produce a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a main parameterisable electronic braking control unit with a main configuration memory for storing braking parameters particular to the vehicle for control of vehicle brake force according to vehicle loading a further electronic vehicle management control unit including a further configuration memory for storing management parameters particular to management of the vehicle and wherein said main control unit includes additional electronic storage memory wherein said parameters particular to management of the vehicle are also retainable and means operable to effect entry of said management parameters from said additional memory to a configuration memory of an unparameterised electronic control unit when substituted for said vehicle management control unit.
