Control Modes

Manages multiple input mapping profiles that change how physical controls are interpreted. Each mode can remap, scale, and smooth input axes differently — useful for vehicles with multiple operating modes (e.g., crane vs. drive mode on utility vehicles).

Drive Modes

Manages vehicle-wide driving profiles (e.g., Comfort, Sport, Eco) that simultaneously adjust multiple systems including engine response, transmission behavior, steering weight, exhaust sound, and suspension stiffness. Provides a unified interface for switching between pre-configured vehicle personalities.
