Electronic brake controller with selectable display

An electronic brake controller for an electropneumatic brake system comprising:

• a housing;
• first and second brake operators mounted to the housing and whose positions dictate desired brake actions when the first and second brake operators are in acceptable positions;
• a display on said housing;
• a signal output provided in the housing;
• and
• a controller unit in said housing determining the positions of said first and second brake operators,
• wherein, when the first and second brake operators are in acceptable combinations of positions said controller unit drives the display to display the desired brake action as a function of the determined positions of the first and second brake operators, and
• wherein, when the first and second brake operators are in don't care combinations of positions, the controller unit drives the display to display one of a plurality of brake system variables based on a position of a multiple position switch.

A method of driving a display on an electronic brake controller, the brake controller having at least one brake operator having a position that dictates a desired brake action, and a multiple position switch on a housing having positions each associated with one of a plurality of brake system variables other than the desired brake action, the method comprising:

• determining positions of the at least one brake operator and the multiple position switch;
• for acceptable positions of the at least one brake operator, driving the display to display desired brake action as a function of the determined position of the at least one brake operator;
• and
• for don't care positions of the at least one brake operator, driving the display with one of a plurality of brake system variables and adjusting the displayed one of the plurality of brake system variables as a function of the position of the multiple position switch for don't care positions of the at least one brake operator.
