• 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
