Modular operator interface system for a work vehicle

A work vehicle, comprising:

• an operator's cab;
• a steering assembly positioned within the cab;
• a first interface module installed within the cab along a left side of the steering assembly, the first interface module including a first module housing and a plurality of first interface elements supported by the first module housing, the plurality of first interface elements including one or more first EH-related interface elements configured to provide one or more operator inputs associated with one or more first EH-based control functions for the work vehicle;
• and
• a second interface module configured to be installed within the cab along a right side of the steering assembly, the second interface module including a second module housing and a plurality of second interface elements supported by the second module housing, the plurality of second interface elements including one or more second EH-related interface elements configured to provide one or more operator inputs associated with one or more second EH-based control functions for the work vehicle;
• a plurality of electro-hydraulic valves, each of the plurality of electro-hydraulic valves being associated with an EH-based control function of the one or more first and second EH-based control functions;
• and
• a controller communicatively coupled to the first and second interface elements and the plurality of electro-hydraulic valves, the controller being configured to control an operation of a respective valve of the plurality of electro-hydraulic valves based on an input received from one of the one or more first and second EH-related interface elements.
