This document describes a motorized smart steering mechanism for large connected vehicles like trucks and buses. It consists of a motorized front cart frame connected to a trailing cart frame through interconnected connecting rods. A single turning motor rotates the front frame, involuntarily turning the trailing frame to follow the same path. Driving motors power the front cart for smooth motion. The mechanism allows efficient turning for long vehicles with a smaller turning radius. Potential applications include parallel parking, high-speed lane changing, and navigating narrow roads with tight bends. The design aims to improve maneuverability at high speeds while combating issues with sharp turns for long vehicles.
