Set To Role

Set To Role (STR)

The Set To Role functional area (F6) provides vehicle-specific role configuration and functionality. This is one of the three extensible screens that support third-party external applications.

Overview

The STR screen allows the vehicle to be configured for its assigned operational role. Different vehicle platforms have different role-specific functionality that can be presented through this screen. When no external application is connected, the screen displays "Waiting for External Application".

External Application Integration

Third-party role-specific applications can render to this screen via the Display Extension Service. This allows vehicle platform integrators to deliver role-specific interfaces within the GVA HMI framework.
