In the dynamic realm of automotive engineering, the efficacy of a vehicle hinges on its array of functions, available through the Feature Architecture developed for each function. Consequently, whether pertaining to propulsion, maneuverability, or occupant safety, these functions are pivotal in defining a vehicle’s design. Embedded within its architecture, each Feature delineates the vehicle’s behavior, components, and performance. Therefore, crafting these Feature Architectures requires meticulous planning, encompassing system definitions, subsystem responsibilities, and performance validation. Engineers drive automotive innovation by mastering this process, yielding vehicles that excel in functionality and performance. 

Vehicle Feature definition: It is a collaboration of the Vehicle mechanical, electrical and software elements – belonging to different subsystems with a specific goal to perform a defined vehicle level function(s).  Example: Front Collision Feature – Provide Occupant protection during Collision.
