System provides the ability of Autonomous Steering with an override capability to allow Normal Control of the vehicle. Motivation for project – Proximity Sensors, Torque Sensors, Interpolation Table, and various system checks. – Traffic Jam Assist, Park Assist, Lane Correction Assist, and Emergency Object Avoidance Assist. Project Overview

Ramp down Autonomous Control upon the driver applying torque. Override Autonomous Control. Ability to update software. Secure data transfer through CAN bus. Alert user up upon failure. Overview of Features

Investigated CAN bus and power steering controller Needed to apply domain knowledge on ECU communications and how a power steering system operates Project Constraints –Safety override –System security –Communication Speed Domain Research
