The Aft Collision Assist (ACA) is an Advanced Driver Assistance System (ADAS)
that is added to a vehicle and integrates with the native systems of that
vehicle. The ACA is used to monitor and reengage a distracted driver of an
approaching vehicle that the ACA system calculates will imminently rear-end the
host vehicle. This work provides a brief overview of existing ADAS that perform
similar functions, the regulatory statutes and requirements that impact the ACA
functionality, and Model-Based System Engineering (MBSE) model diagrams of the
ACA. The MBSE model diagrams presented are State Machine, Conceptual Data Model,
Use Case, System Requirements, and Regulatory Requirements for the entire ACA
system. The MBSE models and regulatory constraints presented within are used to
refine and specify the ACA method of attracting a distracted driver’s
attention.
